Monitoring processes

The PATROL for Linux monitors and manages processes through the NUK_Process applications.

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. You can use the NUK_Process 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)
4. You can manage a process by way of its  NUK_Process 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)
