Release Notes

4.8.38 | 2024-04-21

• New Features: The User Guide has been completely revised. In this context, the portal’s online documentation was also revised and enhanced, which now refers to the corresponding chapters of the user guide.
• Changes:
  • HTTP Test Wizard ‘Output Files’ are now stored in the in the output directory of the test job.
• Bug Fixes:
  • Compiling the code generated by the HTTP Test Wizard failed if the content of an HTTP request was very large.
• Portal Server version 4.8.38 requires now Measuring Agent and Cluster Controller version 4.5.12

4.8.37 | 2024-03-12

• New Features:
  • New Mobile Companion App released. The Mobile Companion is a small Android App that displays a simplified view of the Synthetic Monitoring Dashboard and can receive and display Synthetic Monitoring Alert Notifications.
    • This App gives you an overview of the status of your Synthetic Monitoring Jobs at any time - without having to sign in to the Portal Server.
    • The App also notifies you immediately if a Monitoring Job detects an error or warning.
    • By installing this App on your mobile device, you are always informed whether the operation of your services and servers is working reliably.
    • Documentation and Installation Instructions
• Announcement: Currently the Mobile Companion App can be installed on Android devices only. Support for Apple iOS will be available in around the next 2 months.

4.8.34 | 2024-02-20

• Synthetic Monitoring API Documentation
  • Full Synthetic Monitoring API documentation is now available to support developers to implement their own version of a real-time dashboard for Synthetic Monitoring that can be displayed on their companies screen.
  • The powerful API also supports receiving data for drawing charts and sparklines. In addition, the API documentation contains helpful information about implementation and runtime behavior.
  • See https://kb.realload.com/docs/api/remoteusermonitoringapi/

4.8.31 | 2024-01-18

• New Features:
  • The Welcome Page that appears after ‘Sign Up’ to the RealLoad Portal now displays 3 ‘Test’ examples, all of which can be run as a Load Test, a Synthetic Monitoring Test, and a Regression Test. These 3 examples are also available in the public documentation:
    • Execution of a Simple HTTP/S Test
    • Converting a Selenium IDE Test to a RealLoad Test
    • Developing a JUnit Monitoring Test

4.8.30 | 2023-12-27

• New Features:
  • Synthetic Monitoring: Added configurable performance alert thresholds for the measured time per loop (= average passed session time). Two performance alert threshold values (in milliseconds) can be configured per monitoring job. One to trigger a warning and another to trigger an error. If one of these thresholds is reached or exceeded, a performance warning or performance error is added to the test result, which has the same effect as measuring a “normal” error with a severity of “Warning” or “Error”.
• Portal Server version 4.8.30 requires now Measuring Agent and Cluster Controller version 4.5.11

4.8.29 | 2023-12-17

• New Features:
  • Synthetic Monitoring: Added real-time Sparklines (microcharts) to the Real Time Dashboard. The sparklines with a time range of the last 24 hours show the measured availability for monitoring groups, and for monitoring jobs the measured availability and the measured response times (milliseconds per loop). The displayed time range of the sparklines can be zoomed by clicking on the chart while holding down the mouse button and panning to the right or left in the chart. After releasing the mouse button, the zoom of the corresponding area appears. If necessary, you can then zoom in again to narrow down the area further.

4.8.28 | 2023-12-14

• New Features:
  • Slightly redesigned Synthetic Monitoring user interface.
    • Real-Time Dashboard: The dashboard supports now to show only monitoring groups or only monitoring jobs - or both of them (as before).
    • Real-Time Dashboard: The displayed availability of Monitoring Groups and Jobs for the last 24 hours is now a hyperlink that, when clicked, displays the corresponding statistical chart.
    • All Synthetic Monitoring menus and popups have been revised to make them more descriptive and user-friendly.
• Bug Fixes:
  • Synthetic Monitoring: Webhook alert calls which return a HTTP status code 202 (instead of 200) are no longer logged as failed.

4.8.27 | 2023-12-07

• New Features:
  • Synthetic Monitoring: Support for delayed alert notifications: Alert notifications can now be triggered immediately (as before) or (new) only after one or several repeats. This means that short-period errors and downtimes can be excluded from alert notifications. This does not affect the measured statistics such as availability and detected errors. Delayed alert notification settings can be configured separately for each “Alert Group”, whereby multiple alerts groups can be assigned to one or multiple “Monitoring Groups” and “Monitoring Jobs”.

4.8.26 | 2023-11-28

• New Features:
  • Synthetic Monitoring: Added support for ‘Monitoring Downtimes’. A Monitoring Downtime is a window of time during which synthetic monitoring is temporarily disabled. Multiple monitoring downtimes can be defined for all monitoring groups, or for specific monitoring groups and also for specific monitoring jobs. In addition, a monitoring downtime can be repeated daily, weekly or monthly.

4.8.24 | 2023-11-12

With this new release we have reached the point where a general load testing tool has been crossed with a monitoring tool and also with a regression testing tool - with both the monitoring tool and the regression testing tool are capable of executing test jobs with hundreds or thousands of concurrent users.

• New Features:
  • Real Load Test Suites
    • Test suites are the grouping of multiple test job templates and are executed as a single “run” with different test scenarios.
    • Due to the universal architecture, test jobs of any kind can be part of a test suite (HTTP Test Wizard Jobs, JUnit Jobs, Selenium Jobs ..).
    • The results of the test suite “runs” are archived and can be compared with each other.
    • In addition, the result of a particular test job of a test suite run can be compared with the result of the same test job executed by other test suite runs.
    • All test jobs of a test suite support the powerful ability to be executed with hundreds or thousands of concurrent users and can even executed on a cluster of measuring agents.
    • The test jobs of a test suite are grouped into “execution groups”, where the test jobs of an execution group can be executed in sequential or parallel order.
    • The execution groups can be nested, whereby a separate measuring agent or measuring agent cluster can be defined for each execution group.
    • A “run” of a test suite can be triggered either interactively or via the Remote User API.
  • The following functions have been added to Remote User API:
    • getTestExecutionSuites
    • getCurrentlyRunningTestExecutionSuiteIds
    • startTestExecutionSuiteTestRun
    • getTestExecutionSuiteTestRunResultDetail
    • getTestExecutionSuiteTestRunTestJobOutputFileContent
    • deleteTestExecutionSuiteTestRun
  • Tests: Delete Test: A warning message will now be displayed if the test is referenced by a Monitoring Job or by a Test Suite.
  • Tests: Option “Delete All Unreferenced Tests” added.
  • Load Test Jobs: The display of load test jobs can now filtered by Project and Resource Set.
• Bug Fixes:
  • Starting a load test job failed in rare cases due to a synchronization problem.
• Portal Server version 4.8.24 requires now Measuring Agent and Cluster Controller version 4.5.10

4.8.23 | 2023-09-18

• New Features:
  • Added support for ‘Test Job Templates’.
  • The following functions have been added to Remote User API:
    • getTestjobTemplates
    • defineNewTestjobFromTemplate
    • submitTestjob
    • makeTestjobReadyToRun
    • startTestjob
    • getMeasuringAgentTestjobs
    • getTestjobOutDirectoryFilesInfo
    • getTestjobOutDirectoryFile
    • saveTestjobOutDirectoryFileToProjectTree
    • deleteTestjob

4.8.21 | 2023-09-13

• New Features:
  • Improved integration of JUnit Test with the Real Load architecture. As already described earlier, any JAR file that contains JUnit test can be uploaded to the portal server and executed directly as a test, i.e. without conversion. However, if you are programming a JUnit test from scratch, you can benefit from the additional enhanced features of the Real Load architecture. These additional features include better log output of the executed JUnit test, support for “User Input Fields” (configurable test input parameters), and the measurement and display of additional statistics obtained during test execution.
  • After logging into the portal server, a new project called “Developer Examples” will appear, which contains an example of a JUnit test and shows how a JUnit test can be fully integrated into the Real Load architecture.

4.8.20 | 2023-09-10

• New Features:
  • Added support for executing Selenium IDE tests with Google Chrome.
  • When a Measuring Agent is pinged at application level, it is displayed whether the Measuring Agent supports the execution of Selenium tests.
• Changes:
  • The Selenium version sent to Measuring Agents is now 4.12.1 instead of 4.10.0. However, this only applies to tests that are newly created.
• Portal Server version 4.8.20 requires now Measuring Agent version 4.5.9 when Selenium IDE tests with Google Chrome are executed.

4.8.19 | 2023-09-04

• New Features:
  • Added support for executing Selenium IDE tests. Selenium IDE tests recorded on your local device can be executed as monitoring job and as load test job - by exporting them in the Selenium IDE as ‘Java JUnit’ test and then importing them into the Real Load portal. The imported tests support also ‘User Input Fields’ (configurable options when starting a test) and take a final screenshot of the (virtual) Web browser display just at the end of each test run - which can then be viewed in the Real Load portal. Currently only tests recorded with Firefox are supported. Support for tests recorded with Chrome and Edge will be added soon.
  • Added support for executing JUnit 4 tests. JAR files which contain ready-to-use JUnit @Test(s) can be uploaded to the Real Load portal and run directly as a monitoring job and as a load test job. The benefit of running JUnit tests on the Real Load infrastructure is firstly that they can be run as a “monitoring job” and secondly that they can be run as a “load test job” with many hundreds of JUnit tests, running concurrently in parallel (or even with many thousands of JUnit tests running in parallel, through the use of a cluster of Real Load Measurement Agents). However, this is usually only useful for JUnit tests which are testing or stressing network services of any kind.
• Portal Server version 4.8.19 requires now Measuring Agent and Cluster Controller version 4.5.8

4.8.17 | 2023-07-29

  • HTTP Test Wizard: The URL HTTP timeout can now specified in milliseconds (instead of seconds).

4.8.14 | 2023-06-29

• New Features:
  • Revised Sign-Up: When sign-up, two shared Measuring Agents are now assigned to the new user account.
  • For customers (user accounts) who do not operate their own HTTP/S Remote Proxy Recorder, a temporary HTTP/S Remote Proxy Recorder from a pool is now assigned each time they sign-in.
  • Synthetic Monitoring: A warning sign is now displayed for Monitoring Groups for which no Measuring Agent have been defined.
• Portal Server version 4.8.14 requires now HTTP/S Remote Proxy Recorder version 1.1.3, and Measuring Agent and Cluster Controller version 4.5.7

4.8.13 | 2023-06-20

• New Features:
  • HTTP Test Wizard ‘URL Plugins’ can now be assigned in one step to multiple or all URLs of a HTTP/S session.
• Changes:
  • Sent SMS messages now have the sender ID ‘RealLoad’ instead of a (technical) phone number.
• Bug Fixes:
  • Synthetic Monitoring: No alert was send at monitoring group level when an execution timeout occurred.

4.8.12 | 2023-06-07

• New Features:
  • Measuring Agents which are shared with other Portal Server user accounts (other customers) are now marked with [P] = ‘partial shared’ or [S] = ‘fully shared’ in the Measuring Agents menu. Measuring Agents that are operated exclusively for a specific customer do not have such a mark.
  • The ‘My Account -> Price Plan’ menu shows now the number of sent SMS monitoring alerts of the current month, and also of the last 12 months.
  • Price Plan limits for Synthetic Monitoring have been implemented and are now shown in the ‘My Account -> Price Plan’ menu.
• Changes:
  • The primary Mobile Number for main user accounts and team member accounts no longer needs to be unique across all Real Load accounts.
  • Measuring Agent Housekeeping: The data of executed jobs older than 30 days are now deleted on Measuring Agents (monitoring jobs + load test jobs).
• Bug Fixes:
  • Team member accounts with read/only privileges could make changes to the Synthetic Monitoring configuration.

4.8.10 | 2023-05-11

• New Features:
  • HTTP Test Wizard
    • ‘Conditional Jump’ session element added. For example, this new session element allows a webpage to be called in a loop until the received content contains a certain value, or until a maximum number of conditional jumps is exceeded. Adding multiple conditional jumps per session is supported, with the ability to jump backwards or forwards. The condition of whether to jump and where to jump can be determined by variable values.
    • Java JVM warm-up before starting a test. Tests that run with only one or a few users and loops are now more accurately measuring URL response times by performing a Java JVM warm-up before starting the test.
    • The log-data of measured errors have been improved (less but more meaningful data).
  • Projects Menu
    • The preview of the test results shows now additionally the ‘Avg. Passed Session Time’.
  • Load Test Jobs Menu
    • A new delete option ‘All Completed Jobs - Except the Last Ones’ has been added.
  • Test Results Menu
    • The ‘Avg. Passed Session Time’ is now show in the Summary Statistic.
    • Searching for Text values in an Error Detail ‘Log’ and in an Error Detail ‘Context’ is now supported.

    • Errors reported at URL level are no longer additional reported at Measurement Group level.
  • Test Execution
    • The number of stored errors is now limited to 2000 fully stored errors plus 8000 partial stored errors (partial stored: without error log and without error context).
• Portal Server version 4.8.10 requires now Measuring Agent and Cluster Controller version 4.5.6
• To take advantage of the new features you have to re-generate and re-compile the Java source code in the HTTP Test Wizard.

4.8.8 | 2023-04-05

• New Features:
  • Menu Measuring Agents
    • Measuring Agent Log File: The log file is displayed faster in the browser and supports now searching for text fragments. The time zone of the log file is now also displayed.
    • List Remote Test Jobs: The display of the Job Type was added (‘Load Test’ or ‘Monitoring’).
• Bug Fixes:
  • In rare cases the start a job failed on Measuring Agents.
  • In rare cases the Synthetic Monitoring Availability Chart did show wrongly a green bar (OK) instead of a red bar (Error).
• Portal Server version 4.8.8 requires now Measuring Agent and Cluster Controller version 4.5.5

4.8.7 | 2023-03-26

• New Features:
  • Synthetic Monitoring
    • “Statistics” Submenu added which shows statistics and charts of monitoring groups and monitoring jobs, such as availability, cumulated error time and performance. The time range can be selected arbitrary. In addition, single, historical measurements can be selected and their details displayed (e.g. to analyze a measured error).
    • The Real Time Dashboard shows now for the monitoring jobs the availability of the last 24 hours in percent.

4.8.4 | 2023-03-03

• New Feature:
  • The Synthetic Monitoring Real Time Dashboard shows now the (average) performance of the last executed monitoring jobs in the unit of milliseconds per passed loop. Background information: A monitoring job can be defined with a strength of up to 5 concurrent users and with up to 5 test-loops per user. This value shows the average execution time of the successful executed test-loops overall concurrent users.

4.8.3 | 2023-02-28

• New Features:
  • Synthetic Monitoring added: The same scripts used for load testing can now also be used to periodically check the uptime and performance of your critical business transactions. This means that a Monitoring Job can be defined from an already existing Test (similar as to define a Load Test Job). The Monitoring Jobs can be combined to Monitoring Groups whereby each Monitoring Group can have its own settings. Multiple Measuring Agents can be assigned to a Monitoring Group in order that the assigned Monitoring Jobs are executed from several, different locations (for example from New York, Berlin and Singapore). Supported Monitoring Alert Devices are Email, SMS and Webhooks.
  • WebSocket API for Synthetic Monitoring added: This WebSocket API enable developers to implement their own version of a Synthetic Monitoring “Real Time Dashboard”.
• Portal Server version 4.8.3 requires now Measuring Agent and Cluster Controller version 4.5.4

4.7.3 | 2022-8-28

• New Features:
  • HTTP Test Wizard: New menu “URL Explorer” added. The URL Explorer shows all the details of the recorded HTTP session data and also supports searching within it. Furthermore, the URL Explorer also contains a “Variables Wizard” which displays all distinct values clearly sent in an HTTP session and makes it much easier to extract and assign session variables.
  • HTTP Test Wizard / Review and Edit URL Settings: This menu has been revised and enhanced. Two new auto-configurations wizards are available with which the content of HTTP responses can be automatically checked for keywords and with which the parallel execution of HTTP calls can be configured automatically.
  • HTTP Test Wizard / Debugger: UI improved.
  • A new “Text Phrase Tool” has added. This tool determines the most meaningful human-readable text phrases or keywords from any given content (HTML/JSON/XML). This tool has also been integrated into the HTTP Test wizard.
  • Remote Proxy Recorder: “URL Filter Quick Setting” menu added.
  • Remote Proxy Recorder: “Convert Recording to HTTP Test Wizard Session” improved and enhanced.
  • Portal Server (all menus): Large screen support has been improved.
  • Admin Menu: Mobile Companion API integrated and “Mobile Companion App - Test & Logs” menu added.
• Bug Fixes:
  • HTTP Test Wizard / Generate Code: The measured statistic IDs of executed load tests have now the same values as the indexes of the HTTP Test Wizard session elements.
  • Load test programs generated by the HTTP Test Wizard did not correctly measure the response time in some cases when an HTTP response had no response content (bug fix in com.dkfqs.tools.jar, new version 2.3.0).
• Portal Server version 4.7.3 requires now Measuring Agent and Cluster Controller version 4.5.0, and Remote Proxy Recorder version 1.0.0

4.6.8 | 2022-5-19

• Bug Fixes:
  • Adding of cluster members to AWS/EC2 ‘Cluster Controller’ instances which have launched by cloud credits did fail.
  • The status of cluster jobs was not updated by the real-time monitor.
  • Deleting of test jobs did fail if the corresponding cluster was no longer defined.
  • Starting of cloud instances is now prevented if the portal’s internal monitoring system is no longer working.

  • AWS/EC2 ‘Remote Proxy Recorders’ can now be started by cloud credits.
  • Preview of ‘Remote Proxy Recorder CA Root Certificate’ added when downloading a remote proxy recorder CA root certificate.
  • 40 seconds countdown to left navigation added when launching EC2 instances by cloud credits.

4.6.5 | 2022-5-10

• New Features:
  • Support for team member accounts added:
    • Depending on the license (price plan), a normal user (main user) can also define sub-users (so-called team member accounts).
    • Team members can login as usual, with their email and password.
    • Team members can either have the same rights as the main user or alternatively only have read rights.
    • The team members (including the main user) can communicate with each other via push messages. The portal also shows which team member is currently online. Offline team members receive an email instead of an online push notification.
    • A list of all team members is provided for each team member (inclusive the main user), which contains the profile text and profile image of each team member.
    • Team member accounts are not portal-wide ‘public users’, and cannot act as public technical expert.
• Bug Fixes:
  • Deleting of test jobs did fail if the corresponding measuring agent was no longer defined.

4.6.4 | 2022-4-18

• New Features:
  • Support of special licenses to top up the amount of ‘Cloud Credits’.
  • License restrictions on the maximum number of Measuring Agents and Remote Proxy Recorders no longer apply when such components are launched by spending Cloud Credits.
  • The Web Browser interface has been optimized to support large screens.

4.6.2 | 2022-4-12

• New Features:
  • Support of ‘Sign in with Microsoft’ added.

4.6.0 | 2022-4-10

• New Features:

  • The additional data transfer costs of AWS/EC2 instances which are started via the Portal Server are now billed via Cloud Credits.
  • A new Measuring Agent version 4.1.0 is available which is able to automatically configure the Java memory of the ‘Data Collector’ and the Java memory of executed Java test programs.
• Portal Server version 4.6.0 supports Measuring Agent version 4.0.4 and version 4.1.0

In order to enable the automatic Java memory configuration of a Measuring Agent 4.1.0, the following Java program arguments must be set in the startup script: -autoAdjustMemory -osReservedMemory 1GB

Furthermore, the Java memory of the Measuring Agent should be set in the startup script as shown in the table below:

Example: sudo -H -u dkfqs bash -c ‘CLASSPATH=/home/dkfqs/agent/bin/bcpkix-jdk15on-160.jar:/home/dkfqs/agent/bin/bcprov-jdk15on-160.jar:/home/dkfqs/agent/bin/bctls-jdk15on-160.jar:/home/dkfqs/agent/bin/DKFQSMeasuringAgent.jar;export CLASSPATH;nohup java -Xmx512m -DdkfqsMeasuringAgentProperties=/home/dkfqs/agent/config/measuringagent.properties -Dnashorn.args="–no-deprecation-warning" com.dkfqs.measuringagent.internal.StartDKFQSMeasuringAgent -autoAdjustMemory -osReservedMemory 1GB 1>/home/dkfqs/agent/log/MeasuringAgent.log 2>&1 &’

4.5.0 | 2022-3-27

• New Features:
  • Amazon AWS/EC2 instances of ‘Measuring Agents’ and ‘Cluster Controllers’ can now be started directly in the Portal Server - without the customer needing an Amazon AWS account. The costs of such started AWS/EC2 instances are charged to the customer via so-called ‘Cloud Credits’, whereby the number of ‘Cloud Credits’ can be purchased as an integral part of a license or can also be purchased separately. For customers who register for the first time at the Portal Server, a free amount of ‘Cloud Credits’ will be credited to allow them try out this functionality. Note: It is still fully supported to launch Amazon AWS/EC2 instances of ‘Measuring Agents’ and ‘Cluster Controllers’ with your own Amazon AWS account by using the standalone tool ‘Desktop Companion’.
  • User Top Navigation: Link to Download Server and to Real Load Store added (both links are manageable by the administrator menu).
  • HTTP Test Wizard: Review and Edit URLs menu added.
  • Launched Cloud Instances menu added.
  • Cloud Credit Statement menu added.
  • Measuring Agents & Cluster Controllers menu: The ‘List of Predefined AWS/EC2 Measuring Agent AMIs’ shows no longer incompatible AMI versions.
  • The following new functions have been added for administrators:
    • User Accounts menu: Cloud Credit Statement menu per user added.
    • Server Settings menu: AWS/EC2 Cloud Provider API Settings section added.
    • Customize Auth Users Navigation menu: Download Components and Shop sections added.
    • Cloud Providers & Instance Type Credit Costs menu added.
    • Inspect AWS/EC2 Cloud Instances menu added.
    • Launched Cloud Instances menu added.
    • Cloud Credit Transactions menu added.

Advantages and disadvantages of ‘Cloud Credits’ versus launching AWS/EC2 instances by the ‘Desktop Companion’:

Benefits of ‘Cloud Credits’:

• Full cost control. Cloud instances are automatically terminated after a selected time.
• Easy to use. Seamless integration with the portal server.
• No Amazon AWS account required and therefore no security issue for unauthorized AWS access.

Advantages of the ‘Desktop Companion’:

• Lower costs for cloud instances compared to ‘Cloud Credits’(AWS self-cost are charged only).
• Suitable for customers who use cloud instances frequently and are aware of AWS/EC2 costs involved.

4.4.4 | 2022-1-30

• New Features:
  • Load-releasing Clusters of Measuring Agents are now supported. In order to operate a cluster, a separate process/component is required (so-called “Cluster Controller”) which is not part of the portal server and is operated by the customer himself. Cluster-Features:
    • Multiple clusters can be registered in the portal server using the UI, and the cluster members (measuring agents) can be assigned to the clusters with simple clicks.
    • Depending on the power of the Cluster Controller, a cluster can have several 100 members, which allows to perform load tests of almost unlimited strength (up to millions of concurrent users).
    • A cluster job can be started as easily as a normal job. The only difference is that a cluster is selected for execution instead of a single measuring agent.
    • Optionally, the content of input files can be automatically divided among the cluster members (e.g. if they contain user account credentials).
    • Cluster jobs support all runtime features like normal jobs: suspend job, resume job, stop job and kill job. Entering annotations at runtime is also supported.
    • The real-time display of cluster jobs is exactly the same as for normal jobs, but the statistics displayed at real time already contain the combined values of all cluster members. In addition, a table about the current operating status of each cluster member is available.
    • After a cluster job has been completed, the test result contains the combined values of all cluster members (analogous to the real-time display). In addition, the individual test results of the cluster members can also be displayed.
  • The following functions have been added to the “Remote User API”:
    • getMinRequiredMeasuringAgentVersion
    • getMinRequiredClusterControllerVersion
    • getMinRequiredProxyRecorderVersion
    • getMeasuringAgentClusters
    • getClusterControllers
    • pingClusterController
    • addMeasuringAgentCluster
    • addMemberToMeasuringAgentCluster
    • removeMemberFromMeasuringAgentCluster
    • pingMeasuringAgentClusterMembers
    • setMeasuringAgentClusterActive
    • deleteMeasuringAgentCluster
  • Portal Server “Measuring Agents” menu: The AWS/EC2 popup highlights now incompatible AMI versions.
  • Portal Server “Test Jobs” menu: The log files of executed jobs can now directly copied to the project tree.
• Bug Fixes:
  • A test job can now also have the state “execution failed”.
• Portal Server version 4.4.4 requires now Measuring Agent version 4.0.4

4.3.23 | 2021-11-13

• New Features:
  • HTTP Test Wizard: New Session Element ‘Outbound IP Address’ added. In order that this element can be used, multiple valid IP addresses must be assigned to the network interface of the Measuring Agent(s).
  • HTTP Test Wizard: Support of specific HTTP processing timeout per URL added.
  • Test Results: Support of annotation and annotation events added. The annotation and annotation events can be added at runtime during the test and are shown in the test result. In addition, annotation events can also be reported via the All Purpose Interface and generated, for example, by HTTP Test Wizard plug-ins.
• Bug Fixes:
  • The cached HTTP Test Wizard Session in the Portal Server UI is now updated when a variable is defined, modified or deleted, and when a variable extractor or a variable assigner is deleted.
  • Invalid Java code was generated by the HTTP Test Wizard if the error handling of URLs was set to ‘Continue as usual’.
  • Performance bottleneck fixed in com.dkfqs.tools.http.HTTPClient (occurred since previous version 4.3.22).
  • An incorrect error exception was thrown in com.dkfqs.tools.crypto.EncryptedSocket when an SSL handshake timeout occurred
  • Realtime charts sometimes showed inexact measurement results.
• Portal Server version 4.3.23 requires now Measuring Agent version 3.9.33 and DKFQS Tools version 2.2.25

4.3.22 | 2021-10-24

• Documentation: All Purpose Interface added.
• The All Purpose Interface has been extended by 3 new statistics types that can be declared at runtime:
  • average-and-current-value : An average and current value
  • efficiency-ratio-percent : An efficiency ratio in percent (0..100%)
  • throughput-time-chart : A chart of a throughput per second
• The measurement results of the HTTP Test Wizard now contain the following additional test-specific values (if the executed HTTP Test Wizard session contains URL session elements):
  • Total Bytes Sent
  • Total Bytes Received
  • Network Throughput in Mbps (real-time: current value, test result: average value and chart)
  • Average TCP Connect Time in milliseconds (real-time: + latest value)
  • Average SSL Handshake Time in milliseconds (real-time: + latest value)
  • HTTP Keep-Alive Efficiency (0..100%)
• Bug fix: The time in the name of the test result files is now always set in the time zone of the portal server, regardless of which time zone the Measuring Agents are operated.
• Portal Server version 4.3.22 requires now Measuring Agent version 3.9.32 and DKFQS Tools version 2.2.24

4.3.21 | 2021-09-18

• Searching for a text in all files of the project tree is now supported.
• Support to upload files by drag and drop added.
• Bug fix for assigning variables to HTTP requests in HTTP Test Wizard debugger.
• Bug fix on real time statistics and test results if the measured unit is other than ms.
• User profile images can now have a max size of 400 KB instead of 200 KB.
• CA Root Certificates of HTTP/S Proxy Recorder(s) can now be downloaded via the Portal Server UI.
• Documentation: User Guide added.
• SNMP Plug-In published at https://portal.realload.com/publicPublishedPlugins

Portal Server Installation / Ubuntu 20: The “fontconfig” package has to be installed in order that the captcha generator is working:

sudo apt-get update
sudo apt-get install fontconfig

4.3.20 | 2021-08-07

• HTTP Test Wizard Plug-Ins can now be published and are then available to other users.
• The following HTTP Test Wizard Plugin fields are now protected by algorithms and cannot be manually modified by the JSON editor:
  • pluginId
  • authorNickname
• A (new) “Resources Library” project is automatically created for each user in the Project Tree which contains by default the following “Resource Sets”:
  • “HTTP Test Wizard Plug-Ins”: by default empty
  • “Java”: contains always the latest version of com.dkfqs.tools.jar
  • “PowerShell”: contains always the latest version of DKFQSLibrary2.psm1
• The “Resources Library” project contains common resources which are used by multiple projects. The users can add additional resource sets and files as needed to this project.
• The file com.dkfqs.tools.jar is no longer copied to the corresponding resource set when a HTTP Test Wizard test is generated. Instead of this the generated test contain now a reference to “Resources Library / Java / com.dkfqs.tools.jar”.
• New created HTTP Test Wizard Plug-Ins contain now by default a reference to the resource file “Resources Library / Java / com.dkfqs.tools.jar”.
• More than 50 minor bugs have been fixed and some improvements have been made to the portal user interface.
• Portal Server version 4.3.20 requires now Measuring Agent version 3.9.31
• Existing tests and plug-ins should be upgraded to use com.dkfqs.tools.jar version 2.2.21 (located at “Resource Sets / Java”). This means that the tests have to be generated and defined once again.
• The tuning parameters of Linux operating systems on which “Measuring Agents” run must be increased:

in /etc/security/limits.conf add or modify:

# TCP/IP Tuning
# =============
* soft     nproc          262140
* hard     nproc          262140
* soft     nofile         262140
* hard     nofile         262140
root soft     nproc          262140
root hard     nproc          262140
root soft     nofile         262140
root hard     nofile         262140

Enter: systemctl show -p TasksMax user-0

output: TasksMax=8966

if you get a value less than 262140 then add in /etc/systemd/system.conf

# System Tuning
# =============
DefaultTasksMax=262140

Reboot the system and verify the settings. Enter: ulimit -n

output: 262140

Enter: systemctl show -p TasksMax user-0

output: TasksMax=262140
