Examining Log Files on an Instance

Use log files to identify what's occurring on an instance to help troubleshoot issues.

Windows Logs

Instance Type	Log File Location
OCI	`/var/lib/oracle-cloud-agent/plugins/oci-osmh/osmh-agent/stateDir/log/osmh-agent.log` `/var/lib/oracle-cloud-agent/plugins/oci-osmh/osmh-agent/stateDir/log/osmh-cmd.log` `/var/log/oracle-cloud-agent/plugins/oci-osmh/oci-osmh.log` `/var/log/oracle-cloud-agent/agent.log`
On-premises or third-party cloud	`/opt/oracle/mgmt_agent/plugins/osmh/stateDir/log/osmh-agent.log` `/opt/oracle/mgmt_agent/plugins/osmh/stateDir/log/osmh-cmd.log`
Management stations	`/var/log/httpd/access_log` `/var/log/httpd/error_log` `/var/log/httpd/ssl_access_log` `/var/log/httpd/ssl_error_log`

Examining the plugin log can be useful if the instance can't communicate, isn't checking in with the service, or isn't picking up jobs.

Linux

Run the following with root permissions. These examples use the OCI instance log location.

To view current log activity:

tail -f /var/lib/oracle-cloud-agent/plugins/oci-osmh/osmh-agent/stateDir/log/osmh-agent.log

To check for errors or failures:

grep -i -e error -e fail /var/lib/oracle-cloud-agent/plugins/oci-osmh/osmh-agent/stateDir/log/*

To check for workrequests:

grep osmhworkrequest /var/lib/oracle-cloud-agent/plugins/oci-osmh/osmh-agent/stateDir/log/*

Windows

To view current log activity, run the following as an administrator:
