## Check process resources regarding cpu and memory

Script: `check_proc_ressources`

Show processes that consume the most memory or cpu.
You get a list with usage, process id and process

## Requirements

Nothing special.

## Standalone installation

From this repository ypu need next to this script:

* `inc_pluginfunctions` shared function for all IML checks written in bash

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
