What Do I Do If ICAgent Restarts Repeatedly After Being Installed?

Background

ICAgent restarts repeatedly after being installed.

Impact on the System

ICAgent metrics/logs cannot be collected.

Possible Causes

• The resource usage exceeds the limit of ICAgent.
• ICAgent is abnormal.

Fault Locating

1. Log in to the ECS where ICAgent is installed.
2. Run the cd /var/ICAgent command to go to the ICAgent log directory.
3. Query the current log file to check whether the resource usage is abnormal.

   cat oss.icAgent.trace| grep 'icagent exit'

   • If any command output is displayed, there is a resource abnormality. Troubleshoot it.
   • If no command output is displayed, the resource usage is normal.

4. Query historical log files to check whether the resource usage is abnormal.

   zgrep 'icagent exit' *.zip

   • If any command output is displayed, there is a resource abnormality. Troubleshoot it.
   • If no command output is displayed, the resource usage is normal.

5. Query the ICAgent startup log file to check whether ICAgent is abnormal.

   cat oss.script.trace | grep runtime

   • If any command output is displayed, there is a ICAgent abnormality. Troubleshoot it.
   • If no command output is displayed, ICAgent is running properly.

6. Query the historical ICAgent startup log files to check whether ICAgent is abnormal.

   zgrep runtime oss.script.*.zip

   • If any command output is displayed, there is a ICAgent abnormality. Troubleshoot it.
   • If no command output is displayed, ICAgent is running properly.
