Prev Next

In certain instances, the Sensor stays in bad or uninitialized health state indefinitely. The bad health of the Sensor could be due to signature file download failure, or error while starting the Sensor.

You can perform the following high-level troubleshooting steps to trace the error:

  1. Execute the following commands and check the output for any errors:

    • show

    • status

    • show sensor health

    • show startup stats

  2. Check if the hardware is connected correctly.

  3. Check the InfoCollector tool for logs and the configuration backup.

  4. Check if the issue is due to signature file download failure. If it is due to the aforementioned error, contact Trellix Support for further assistance.

  5. Execute show startup stats debug CLI command and check the output for any errors.

    IntruDbg#> show startup stats
