Location of Log Files

If you experience any issues with Gremlin not working correctly the best place to start the investigation is the error log files.

Logs can be found under the /var/log/gremlin directory. Agent logs can be found in the daemon.log file. Log entries in this file may indicate events where the Gremlin Agent is not able to communicate with the Control Plane.

Each fault injection performed by the Agent is logged under /var/log/gremlin/executions using its unique attack execution ID. This is useful for troubleshooting attacks that do not complete.

If you're submitting a Support ticket, please include the log files along with additional helpful information such as the attack id (if applicable) for the investigation.
