Various Linux Kernel Counters

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

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), processes (the number of process creations per second), pswpin (the number of written swap pages to disk) and pswpout (the number of read swap pages from disk).

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. For Page Swap In and Page Swap Out both upper and lower levels can be set.


One service is created for "Major Page Faults", "Context Switches", "Process Creations", "Page Swap In" and "Page Swap Out" on each host.
