Why does Dynatrace process group show wrong values

The application is healthy but the graph related to process group shows dips (see the enclosure) every few hours as if the app is down.  We noticed this kind of trend for several apps.

We are using the following query-

(builtin:pgi.availability:filter(and(or(in("dt.entity.process_group_instance",entitySelector("type("PROCESS_GROUP_INSTANCE"),entityName.contains("na-6y")"))))):splitBy("dt.entity.process_group_instance"))

How many instances of process you have in this PG?

It could be a issue with a process crashing and restarting intermittently or process becoming unresponsive because of resource constraints on server or few other issue

Do you see anything written in the process logs?

Hi @e770144 

You can verify the status of the monitored processes under each host and make sure it's not shown as inactive.

  • in case it's shows "process restart is recommended to get full visibility", proceed with process restart after working hours.
  • this situation is common after oneagent deployments and version updates.
