Absence of data in the Pods tab or some tabs in the Kubernetes monitor
This is a known issue in the older version of Applications Manager, which is fixed in APM v16800. So, we recommend upgrading the Applications Manager to the stable version to properly fix this issue.
To collect data for the Kubernetes Monitor, Applications Manager uses the SSH protocol to connect to the Kubernetes server and execute
kubectl commands. However, a timeout issue may occur while collecting data if the environment has a large number of pods. To resolve this issue, follow the steps given below:
- Use ServerSSHTroubleshoot.bat or sh file from <APM_Home>\bin\troubleshooting to establish an SSH connection with the Kubernetes server.
- Execute the "kubectl get pods -o json --all-namespaces" command and calculate the time taken for the command to complete.
- Edit the Kubernetes Monitor from the Applications Manager GUI.
- Update the Timeout value to the time taken for command execution (in seconds).
- Update the polling interval to twice the Timeout value (in minutes).
For example, if the command execution time is 300 seconds, update the Timeout value to 300 seconds and the polling interval to 10 minutes.
If the issue persists, send an email to appmanager-support@manageengine.com with a screenshot of the "Edit Monitor" page after clicking on the Test credentials option along with the latest Support Information File (SIF) from Applications Manager with print all logs enabled for analysis.
