Appendix C. Probes 181• Processes — The number of processes running simultaneously on the machine.Field ValueCritical Maximum ProcessesWarning Maximum ProcessesTable C-70. RHN Satellite Server::Processes settingsC.10.9. RHN Satellite Server::Process HealthThe RHN Satellite Server::Process Health probe monitors customer-specified processes and collectsthe following metrics:• CPU Usage — The CPU usage percent for a given process.• Child Process Groups — The number of child processes spawned from the specified parent process.A child process inherits most of its attributes, such as open files, from its parent.• Threads — The number of running threads for a given process. A thread is the basic unit of CPUutilization, and consists of a program counter, a register set, and a stack space. A thread is alsocalled a lightweight process.• Physical Memory Used — The amount of physical memory in kilobytes being used by the specifiedprocess.• Virtual Memory Used — The amount of virtual memory in kilobytes being used by the specifiedprocess, or the size of the process in real memory plus swap.Specify the process by either command name or process I.D. (PID). Entering a PID will override theentry of a command name. If no command name or PID is entered, the error Command not foundwill be displayed and the probe will be set to a CRITICAL state.Field ValueCommand NameProcess ID (PID) fileTimeout* 15Critical Maximum CPU UsageWarning Maximum CPU UsageCritical Maximum Child Process GroupsWarning Maximum Child Process GroupsCritical Maximum ThreadsWarning Maximum ThreadsCritical Maximum Physical Memory UsedWarning Maximum Physical Memory UsedCritical Maximum Virtual Memory UsedWarning Maximum Virtual Memory Used
