Check manual page of kernel

Various Linux kernel counters

This check monitors various counters as found in /proc/stat and /proc/vmstat. Examples for those counters are ctxt (the number of process context switches per second), pgmajfault (the number of major page faults per second) and processes (the number of process creations per second).

You can set a critical and warning level on each of those counters or just monitor them without levels in order to collect performance data. Levels you set to None will not be checked.

Item

"Context Switches", "Process Creations", "Major Page Faults" or the name of the kernel counter in question as found in /proc/stat or /proc/vmstat.

Discovery

Per default one check for "Major Page Faults", "Context Switches" and "Process Creations" will be created on each host providing that data. You can override this list globally by setting inventory_kernel_counters to a list of strings with those counters that should be inventorized. Use ignored_services if you need a host-specific configuration of the inventory.
