Hello AppDynamics Expert,
There is some issue with our AppDynamics DB Agent. It was working fine 2 weeks ago. I can confirm the network is okay for both the AppD controller and AWS database, and the credential of DB is good, too. But agent.log keeps repeating the below log :
[AD Thread-Metric Reporter1] 28 Apr 2021 07:36:05,475 INFO SystemAgentTransientEventChannel - Full certificate chain validation performed using default certificate file
[AD Thread-Metric Reporter1] 28 Apr 2021 07:36:05,498 ERROR MetricService - HTTP Request failed: HTTP/1.1 500 Internal Server Error
[AD Thread-Metric Reporter1] 28 Apr 2021 07:36:05,499 WARN MetricService - Error sending metric data to controller:null
[AD Thread-Metric Reporter1] 28 Apr 2021 07:36:05,499 ERROR MetricService - Error sending metrics - will requeue for later transmission

I see a lot of people have the same issue when I google the issue but no resolution yet. Do you have any idea?
