Recovering the Virtual Machine

The staros_monitor service is responsible for monitoring the deployed UPF VMs. You can verify the status of the systemd service using the following command:
systemctl status staros_monitor 

You must ping the UPF VFNM interfaces repeatedly until the staros_monitor service recovers an unhealthy UPF VM. Also, the staros_monitor service restarts the UPF in the following conditions:

  • When the UPF VM is stopped.

  • When the UPF VM is running but not responding to the ping command.

Note

For troubleshooting any issues, you can view the logs captured in the /var/log/staros_monitor.log file. Also, you can configure the failure occurrence and Ping interval through /data/upf/monitor/staros_monitor.cfg file. You must restart the staros_monitor service for the changes to take effect.
