Complete CPU and Memory check for UNIX – cperf.sh

This is a plugin that monitors CPU, memory and swap utilization related.
It can monitor cpu and memory for more complex output with swap analysis and blocked processes, alarming as critical only in cases where paging and locked processes exist.
This script is able to get status of CPU, memory and swap
It can monitor cpu and memory for more complex output with swap analysis and blocked processes, alarming as critical only in cases where paging and locked processes exist.
To use the script you need to specify whether to monitor cpu or memory using the cpu or mem flag, and including the thresholds for warning and critical next.
Example:
server: / #./cperf.sh
Invalid parameter.
Use: # cperf.sh mem V1 V2 or
# cperf.sh cpu V1 V2
V1 = warning percentage value
V2 = critical percentage value

server: / #./cperf.sh mem 85 95
OK – MEMORY usage at 62 % – SWAP usage at 22 %

server: / #./cperf.sh cpu 85 95
OK – CPU usage at 1 % – 3 processes running – 0 processes blocked

The idea is to generate fewer alerts and generate critical alerts only when there is really CPU contention or low memory, thus eliminating peak usage alerts.
