Hi.
Custom process group detection rules can indeed break out process instances based on command line arguments (though please kindly see my final remark).
Process groups created by custom process group detection rules do not currently automatically appear in Technology Overview. In order to navigate to them, you should go through a specific process group instance on the host screen.
Once you have configured custom process group detection rules, please go to the screen of the host where given process group instance is running. Please note that custom process groups are not displayed on the main host screen. You should navigate to the ‘all processes’ screen. There, you should see your custom process group instance. When you click process group instance in question you will be taken to its screen, from where you can navigate to process group
screen via the ‘View process group’ button.
If on one host you have processes belonging to different custom process groups, you should see their instances as separate entries on the ‘all processes’ screen. At the time of this answer creation there is no additional screen, which allows for side-by-side comparison of custom process groups.
Please note that both on process group instance screen and on the process group screen you will see the command line arguments you have used to distinguish your processes.
Custom process group detection does not require any restarts to monitored processes.
As soon as OneAgent receives new configuration, it will be applied. It shouldn’t take more than a minute before you are able to see result of your configuration changes.
As a final remark, please note that custom process grouping is available only for process types that are not automatically discovered by Dynatrace. If, before your changes, your processes are not of type ‘other’, this method cannot be used to divide processes into multiple process groups.
Please let us know if we may be of further assistance related to custom process grouping or any other Dynatrace functionality.
Best regards,
Lukasz
