    The PATROL Knowledge Module for UNIX and Linux monitors and manages processes through the PROCESS and PROCESS_PRESENCE applications and the Process KM Configuration Plug-in for the PATROL Configuration Manager (PCM). 

    With these application classes, you can

    1. Designate specific processes for monitoring
    2. Review the overall status of processes on the system such as
      • Total number of processes
      • Total number of zombie processes
      • List of all zombie processes
      • List of all processes consuming excessive CPU
      • Total number of processes waiting for resources
      • Total number of user (nonroot) processes
      • Average number of processes per user
    3. Reprioritize process by
      • Individual process
      • User ownership
      • Process group membership 
    4. You can use the PROCESS_PRESENCE application class to monitor
      • A single process on a single computer
      • A local process across multiple computers within a process host group (this feature is helpful when you are monitoring processes in a clustered environment)
      • Several running instances of a process on a single computer
      • Several running instances of a process across multiple computers within a process host group (this feature is helpful when you are monitoring processes in a clustered environment)
    5. You can manage a process by way of its PROCESS_PRESENCE instance to

      • Restart a process that has stopped
      • Stop a process
      • Alarm when an unauthorized User ID owns a process
      • Alarm when the number of processes running in a host group drops below a specified minimum number
      • Alarm when the number of processes running in a host group exceeds a specified maximum number
      • Alarm when a process does not have a parent process ID (PPID) of 1 (a PPID of 1 indicates that a process is owned by init)
    6. You can use the plug-in for PCM to configure process monitoring without using a console. See Using the PATROL Configuration Manager to Configure the PATROL KM for UNIX for details.
