Understanding the Apache Server Status Ubuntu Table

The Apache Server Status Ubuntu table shows information about each Apache process, including:

Column	Description
**PID**	The process ID of the Apache child process.
**Acc**	The number of requests this child process has accepted.
**M**	The mode of the Apache child process.
**CPU**	The CPU usage of the Apache child process.
**SS**	The current status of the Apache child process.
