+
+## Introduction
+
+Show processes that consume the most memory or cpu.
+You get a list with usage, process id and process
+
+## Requirements
+
+Nothing special.

+SYNTAX:
+
+  check_proc_ressources -m METHOD [-w WARNLIMIT] [-c CRITICALLIMIT]
+  
+EXAMPLE:
+
+  -h, --help
+      show help
+
+  -c, --critical VALUE
+      critical value; defaults: 
+        * cpu 90
+        * mem 90
+
+  -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 70
+        * mem 70
+
+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.
+
+```
+
+## Examples
+
+### CPU check
+
+`./check_proc_ressources -m cpu -w 50 -c 70` returns
+
+```txt
+OK: all processes below warning limit 200 % Cpu .. (and critical limit 280 %)
+
+Cpus detected: 4
+```
+
+### Memory check
+
+`./check_proc_ressources -m mem -w 10 -c 70` returns
+
+```txt
+WARNING: 1 processes use 10 % .. 70 % Memory
+
+Level       Usage        process id  process
