Liquid Web’s Heroic Support team closely monitors the load on your servers with Sonar® proactive monitoring and service restoration. That said, it’s always wise to glance at what processes are running on your server to assure your services are running as expected. Check-out our tutorial on Monitoring Server Processes with Top for Linux.
Be sure to verify that all of your necessary services are configured to start when the server boots up. For CentOS users, you can follow this tutorial: chkconfig Command Examples for Red Hat and CentOS.
