Dynatrace data is missing. No changes to application.
@Srinivas_Keshava I assume the application is being monitored using OneAgent?
Few things to check..
Is all the data missing or only some type of data not being collected?
Check OneAgent connectivity - OneAgent->ActiveGate->DT . Did something break in between, are the ports still accessible
Check if OneAgent process running ? - Check services
Open OneAgent health overview and check health status and any module errors
Run the diagnostics and look at the logs
Welcome to the community! Adding to what @p_devulapalli covered, here are a few things that often cause data to stop even when the app hasn’t changed:
- Deployment status: Go to Deployment status → OneAgents and check whether the host shows as connected, disconnected, or “no data”. Also look under ActiveGates. If the ActiveGate the agents route through is down, every host behind it goes quiet at once.
- Process restart after an agent update: If OneAgent auto-updated recently, deep monitoring (services, traces) may not resume until the monitored processes are restarted. The host shows up fine, but the service data is missing.
- Monitoring settings: Check that monitoring wasn’t switched off or changed for the host, host group, or process group, e.g. set to infrastructure-only or excluded by a process monitoring rule.
If you can share when the gap started, whether it’s one host or many, and which data types are missing (host metrics vs. services/traces vs. logs), it’ll be much easier to narrow down.
