Check the items to isolate and troubleshoot the issue of high CPU usage on a Deep Security Agent machine.


Isolation Steps

  1. Check which process encounters high CPU utilization:
    • Windows: Task Manager
    • Linux/HPUX: top output
    • Solaris: prstat output
    • AIX: topas output
  2. If ds_agent.exe is encountering high CPU usage, check the version and build of the agent. Make sure that it is the latest version.
  3. The CPU is being used for the cleanup of Integrity Monitoring baselines. This may cause a sudden increase in CPU usage. CPU usage should eventually go down once unused baselines have been purged.

    If the CPU usage continues, try disabling the agent and verify if the issue still occurs. If it does, refer to the information below for the logs to collect.

  4. To control the CPU usage of IM, go to Integrity Monitoring > Advanced.
  5. Under CPU Usage section, set the Integrity Monitoring CPU Usage Level to Low.

  6. Check if there is a recommendation scan being performed. This may also increase CPU usage on target machines.

Logs to Collect for Further Troubleshooting

  • Debug View Log

    5. Launch DebugView.exe and enable the following under Menu > Capture:
      • Capture Win32
      • Capture Kernel
      • Capture Events
    6. Start the Trend Micro Deep Security Agent service.
    7. Check the Task Manager for the CPU usage on the machine. Take a screenshot of the Task Manager.
    8. Export the information in DebugView to a CSV file.
