Requirements for private Synthetic locations
Make sure the host you want to 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.
- As Chromium development for Ubuntu 16.04 stopped at version 90, we can no longer assure a high enough level of stability and security for synthetic monitor execution on Ubuntu 16. We have discontinued our support for installing Synthetic-enabled ActiveGate on Ubuntu 16 after ActiveGate version 1.251. That is, ActiveGate version 1.251 is the last Synthetic-enabled ActiveGate supported on Ubuntu 16. With Dynatrace version 1.254, Synthetic-enabled ActiveGates on Ubuntu 16 can no longer be updated.
- 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, 2022 |
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 |
|---|---|
| 1.261 | 109 |
| 1.257 to 1.259 | 108 |
| 1.255 | 107 |
| 1.253 | 106 |
| 1.251 | 105 |
| 1.245 to 1.249 | 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 | 7.9, 8.4, 8.6 |
| Ubuntu | 16.04, 18.04, 20.04, 22.04 |
| CentOS | 7.9 |
| Amazon Linux 2 |
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. For example, if the latest supported Chromium version is 103, Dynatrace supports up to Chromium version 101. If the provided Chromium version is significantly older for a specific OS, we support only the provided version. 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.
When installing ActiveGate and Chromium from a custom, local repository, you need to resolve all dependencies and enable repositories as required; the custom repository can be used only for Chromium packages, not their dependencies. Place the Chromium package archive and the signature file in the custom repository for installation. If your package archive file is https://synthetic-packages.s3.amazonaws.com/Chromium/snap/chromium-107.0.5304.87-2168.tgz (Chromium 107 for Ubuntu 20 and 22 on ActiveGate version 1.255), you can find the signature file by appending .sig to the URL: https://synthetic-packages.s3.amazonaws.com/Chromium/snap/chromium-107.0.5304.87-2168.tgz.sig.
Note
Chromium development for Ubuntu 16.04 stopped at version 90.

1 Version not provided by Dynatrace. This means that the Chromium version is not available at the time of the ActiveGate release but will be provided by Dynatrace as soon as an official release of the version is available. Dynatrace includes the latest available version from the official distribution. In such cases, Chromium can be autoupdated to the latest version provided by Dynatrace. The specified ActiveGate version will work with the latest supported Chromium version if installed outside of an autoupdate. |
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 because of increased hardware requirements for Chromium. 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. |
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.
