The Apache::Processes probe monitors the processes executed on an Apache Web server and collects the following metrics:
Data Transferred Per Child — Records data transfer information only on individual children. A child process is one that is created from the parent process or another process.
Data Transferred Per Slot — The cumulative amount of data transferred by a child process that restarts. The number of slots is configured in the httpd.conf file using the MaxRequestsPerChild setting.
The ExtendedStatus directive in the httpd.conf file of the Web server must be set to On for this probe to function properly.
