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.
