A server health check is used to determine how healthy a server is. A server health check is usually performed during a system upgrade, maintenance, or troubleshooting.
The steps involved in a server health check depend on the server being checked. For example, a server health checklist includes hardware metrics, reports, alarms, and information about the server’s procurement, usage, and status. In contrast, an application server health check involves testing software components like databases, web applications, and operating systems.
Every server monitoring solution should be a part of checking to see if an application server is behaving differently from similar applications in the same environment.
