When trying to start analytics agent as a machine agent extension for log analytics, the agent send an eception:

Hi @Sergio.Mandujano ,

Thank you for posting to the community.

Could you please delete the file below and restart the machine agent?

/opt/appdynamics/machine-agent/monitors/analytics-agent/analytics-agent.id

The stale pid file can cause the error.

If this doesn't fix the issue, could you please check errors in analytics-agent.log?

Best Regards,

Hiroki
