I'm looking to get the execution path (binary path) for a non-Java process in order to properly group my processes together. I 'could' use process naming and process detection rules to properly group these together if I had this value, but I can't see if Dynatrace is capturing it or not. When I do the dropdown for the 'properties and tags' section it's not present.
Does this mean DT isn't capturing it?
Based on my experience, you cannot use the process detection rules for non-instrumented processes. It never worked for me (e.g. - arbitrary binaries).
I highly recommend setting the DT_CLUSTER_ID variable to properly categorize these processes into process groups you want them to be part of.
