Server Processes Section - Server Processes

The Processes table comes pre-loaded to monitor both the Parent Processes and the Total Children processes. The module tracks CPU and memory usage of these processes, as well as making sure that they are running.

An alarm will automatically be generated if the module detects that the number of Total Children is less than the StartServers directive or greater than the MaxClients directive.
