Unable to Schedule a synthetic Job in appdynamics

Vikash_Vardhan — Fri, 02 Aug 2024 10:10:57 GMT

I have installed AppDynamics locally with a private Synthetic server + PSA Agent in the same host and Controller, EUM in separate hosts.

Now my issue is that whenever I try to schedule a job in AppDynamics in the User Experience dashboard the agent hits the provided URL with some response. It is displayed on the session tab but only one hit is being registered and showed despite scheduling the job to run in every minute.

We have looked into the scheduler-shepherd logs where we're getting below logs:
