Server status: Is the server on-line?
The server status shows a series of information about the server your services run on: Are the different services accessible, is the server overloaded, is a restart of the server planned, etc, etc.
The monitor module evaluates the results it receives from the server and then marks them as being "OK" (green), "WARNING" (yellow) or "CRITICAL" (red), so that you can quickly determine if everything is running as it should, you can also see what the cause of an alarm is. If a service is "WARNING" or "CRITICAL" an automatic alarm goes to the person responsible for monitoring the system, after which the problem is taken care of as fast as possible. No matter the time.
