How do I define tags in a host based configuration file?

Within dynamic or large environments, manual host tagging can be impractical. For dynamic deployments that include frequently changing host instances and names (for example, AWS or MS Azure), you can use a dedicated configuration file to programmatically apply tags to your hosts.

Edit the host tag configuration file

During Dynatrace OneAgent installation, the installer creates a simple hostautotag.conf configuration file on the monitored host. On Windows, the file is located in %ProgramData%\dynatrace\oneagent\agent\config, and on Linux in /var/lib/dynatrace/oneagent/agent/config. The file should contain a list of strings or key/value pairs that will be reported to the server with every file change. New lines or spaces are used to separate tag values. For example:

TestHost Gdansk role=fallback

The tags defined in this example result in the following host tagging:

Configuration file-based tags behave similarly to automated, rule-based tags and environment variable-based tags. Configuration file-based tags can't be removed manually from a host. They can only be removed through a hostautotag.conf file change.

Other options for automated tagging

You can also set up automated tagging of the hosts in your environment using:
