SYNTAX:
check_proc_ressources -m METHOD [-w WARNLIMIT] [-c CRITICALLIMIT]
- METHOD string identify what to check; one of cpu|mem
- WARNLIMIT integer optional: value in percent;
- default: $iWarnLimitCpu (cpu) | $iWarnLimitMem (mem)
- CRITICALLIMIT integer optional: value in percent
- default: $iCriticalLimitCpu (cpu) | $iCriticalLimitMem (mem)
- Remark: for cpu the given value is multiplicated with count of cpu
+EXAMPLE:
+
+ -h, --help
+ show help
+
+ -c, --critical VALUE
+ critical value; defaults:
+ * cpu $iCriticalLimitCpu
+ * mem $iCriticalLimitMem
+
+ -m, --mode VALUE
+ identify what to check; one of cpu|mem
+ Remark: for cpu the given limits are multiplicated with count of cpu.
+
+ -w. --warning VALUE
+ warning limit value; defaults:
+ * cpu $iWarnLimitCpu
+ * mem $iWarnLimitMem
EXAMPLE:
check_proc_ressources -m mem -w 50 -c 70
+ Show processes consuming more than 50% of memory; mark as critical
+ when using 70% and more.
