Ubuntu: Measuring Agent manual install

Wed, 19 Jun 2024 00:00:00 +0000

Prerequisites

Supported Hardware

Amazon EC2 Cloud instances, or
Own hosted Servers with any Intel or AMD CPU, or
Own hosted Raspberry Pi 4 Model B / 8 GB (ARM CPU) / Ubuntu 20 only / for weak load tests up to max. 100 concurrent users (with loop iteration delay = 1000 ms)

Minimum Requirements

Minimum required CPU Cores of Processor: 4
Minimum required Memory: 8 GB
Minimum required Disk: 64 GB
Minimum required Network Speed: 100 Mbps (1000 Mbps or faster strongly recommended)

Usual Requirements

Suggested Hardware for performing load tests up to 500 concurrent users: Intel CPU i3 / 16 GB Memory / Disk: 256 GB
Suggested Hardware for performing load tests up to 1000 concurrent users: Intel CPU i5 / 16 GB Memory / Disk: 512 GB
Suggested Hardware for performing load tests up to 5000 concurrent users: Intel CPU i7 / 64 GB Memory / Disk: 1024 GB

Rule of Thumb for Amazon EC2 Instances

Per EC2 vCPU, 100 virtual users can simulated
Required Memory: 5 GB + (1 GB per 100 virtual users)

Environment and Location

Tests performed from ‘Measuring Agents’ which are virtualized or which run in a container environment measure often incorrect results. Because additional CPU and Network delays occur at virtualization/container level. It’s recommended that you use BARE-METAL-SERVERS to perform your tests. Alternatively you can also use Amazon EC2 Cloud instances.

Ubuntu: Measuring Agent Controller manual install

Fri, 23 Jan 2026 00:00:00 +0000

Measuring Agent Controllers are required to connect outbound connected “Measuring Agents” to the Portal Server. Each Measuring Agent Controller can handle many “outbound” connected Measuring Agents.

The advantage of “outbound” connected Measuring Agents is that they do not require an inbound firewall rule. This makes them relatively easy to install without any administrative effort. However, they must be able to open an “outbound” connection to a “Measuring Agent Controller”.

Outbound connected Measuring Agents support all product features and functionalities as inbound connected Measuring Agents, with the only exception that they cannot be a member of a “Cluster Controller”.

Ubuntu: Cluster Controller manual install

Wed, 19 Jun 2024 00:00:00 +0000

Prerequisites

Supported Hardware

Amazon EC2 Cloud instance, or
Own hosted server with any Intel or AMD CPU

Minimum Requirements

Minimum required CPU Cores of Processor: 2
Minimum required Memory: 8 GB
Minimum required Disk: 64 GB
Minimum required Network Speed: 100 Mbps (1000 Mbps or faster strongly recommended)

Environment and Location

In terms of network technology, the cluster controller should be as close as possible to the cluster members.

The simultaneous operation of a cluster controller together with one or more measuring agents on the same machine is possible, although not recommended. This means that the cluster controller should be operated on its own machine - especially if a cluster contains more than 100 members.

Ubuntu: Remote Proxy Recorder manual install

Sun, 06 Feb 2022 00:00:00 +0000

Prerequisites

Supported Hardware

Amazon EC2 Cloud instance, or
Own hosted server with any Intel or AMD CPU

Minimum Requirements

Minimum required CPU Cores of Processor: 2
Minimum required Memory: 8 GB
Minimum required Disk: 32 GB
Minimum required Network Speed: 100 Mbps (1000 Mbps or faster strongly recommended)

Environment and Location

The Remote Proxy Recorder can be placed at any network location, but the control port must be reachable from the Portal Server.

Ubuntu: Alert Processor manual install

Fri, 08 May 2026 00:00:00 +0000

Prerequisites

The Alert Processor can be installed on any Linux (and Windows) system and requires about 550 MB of physical memory.

JavaScript Processor

The Alert Processor requires a JavaScript Processor which is installed on the same machine.

Email Server

The Alert Processor sends its emails via SMTP. You need an email server which receive and forward these SMTP messages.

Twilio SMS Gateway

The Alert Processor sends its SMS via the Twilio service provider.
You need a customer account for the Twilio SMS Gateway www.twilio.com/docs/sms

Windows: OSHI Daemon installation

Sun, 16 Feb 2025 00:00:00 +0000

Overview

If you have to monitor a Windows based system using the RealLoad OSHI Daemon follow the instructions on this page to install the agent as a service and have it started on boot.

Requirements

The software can be installed on any recent x64 and ARM Windows system.
It requires about 300 MB of physical memory.
You’ll need to execute the installation script mentioned on this page using a Windows privileged account (Administrator).
You’ll need some familiarity with Powershell.

The installation script will:

Install the Microsoft build of OpenJRE 11, without setting any Java environment variables.
Deploy the ReaLoad OSHI Daemon as a Windows service and start it.
Optionally install the RealLoad JavaScript Processor.
Print the Unique Daemon ID at the end of the process.
Set a random AuthTokenValue for the OSHI Daemon.
If the JavaScript Processor is also to be installed, then a random LocalJavaScriptProcessorAuthTokenValue is generated and configured.

The uninstallation script will:

Stop the OSHI and JSP services.
Remove the base installation folder. This will remove all software (including JRE) and config files.
Set the environment variables uniqueDaemonId, installLocalJSP and oshiAlertProcessorHosts. This allows for a simple re-installation.

Installation
