Requirements for private Synthetic locations

Make sure the host you'll use for your private location complies with the following requirements. Note that a Synthetic-enabled ActiveGate has more demanding hardware and system requirements than a regular Environment or Cluster ActiveGate. Dynatrace strongly recommends that you use a Synthetic-enabled ActiveGate exclusively for synthetic monitoring purposes.

Important

Check the latest ActiveGate release notes for the oldest supported ActiveGate versions.

Operating system requirements

A freshly installed ActiveGate can run your private synthetic monitors (both HTTP and browser monitors) on the following operating systems.

Windows

Windows OS	Versions
Windows Server	2016, 2019

Chromium version on Windows

On Windows, the ActiveGate installer package includes the Chromium browser that's used to run browser monitors. The table below shows the Chromium versions that are bundled with the respective ActiveGate versions.

ActiveGate version	Included Chromium version
1.245	103
1.243	101
1.241	100
1.235 to 1.239	99
1.231	96
1.229	95
1.225 to 1.227	92
1.221 to 1.223	91
1.219	90
1.215 to 1.217	89
1.213	88
1.209 to 1.211	87
1.205 to 1.207	86
1.201 to 1.203	84

Unsupported Windows versions for testing purposes only

If you only want to test private Synthetic locations on a non-production host, for example, your own desktop, you can install a Synthetic-enabled ActiveGate on unsupported Windows versions such as Windows 10 or Windows Server 2012.

Antivirus software on Windows

We do not support Synthetic-enabled ActiveGates on Windows hosts that have antivirus software installed. The antivirus software might block the browser used to run the monitors.

Linux

Linux distribution	Versions
Red Hat Enterprise Linux	7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4
Ubuntu	16.04, 18.04, 20.04
CentOS	7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4

Chromium versions on Linux

We strongly recommend that you keep your Linux-based Synthetic-enabled ActiveGates and Chromium versions updated—Dynatrace supports Chromium versions that are no more than two versions behind the latest Dynatrace-supported version for a specific ActiveGate release. (See information on updating Chromium automatically and manually.)

On Linux, the ActiveGate installer downloads the Chromium dependencies that are required by the Synthetic engine. On Red Hat and CentOS, you need to enable particular repositories from which the installer downloads the dependencies. The Dynatrace web UI provides you with all the required commands. For detailed instructions, see Create a private synthetic location.

Note: Chromium development for Ubuntu 16.04 stopped at version 90.

Hardware requirements

Depending on the number of tests executed per hour, Synthetic-enabled ActiveGates need to meet the following hardware requirements.

	XS¹	S	M	L
Minimum CPUs	2 vCPU	4 vCPU	8 vCPU	16 vCPU
Minimum free disk space	20 GB	25GB	30GB	40GB
Minimum RAM	4GB	8GB	16GB	32GB
Minimum free RAM	3GB	5GB	8GB	12GB
Minimum disk IOPS (Windows)	100	200	400	750
Estimated maximum number of HTTP monitor executions/h²	300k	300k	300k	300k
Estimated maximum number of high-resource HTTP monitor³ executions/h	10k	20k	60k	100k
Estimated maximum number of browser monitor executions/h	300	650	1200	2200
¹ Not recommended for Windows Server-based ActiveGates. This is just a minimal requirement. We recommend at least 25 GB of free disk space and 8 GB RAM because of the enhancements planned for future releases. ² Calculated as 5000 monitor executions (maximum for a single environment) run once every minute (maximum frequency). ³ These are HTTP monitors on private locations with any of: pre- or post-execution scripts, OAuth2 authorization, Kerberos authentication.

Limit values

The estimated limits listed in the table above were determined in our internal tests. The actual values might vary depending on the complexity of your monitors.
