Servus allerseits,
heute war ich auf der Suche nach einem fertigen plugin, welches mein qnap nach den gängigen Infos abfragt. Im Nagios-Port fand ich bereits eine Version von Mad-Eye, die allerdings noch die ein oder andere Macke hatte. Dank der super Community habe ich nun eine fertig, funktionierende Version zusammen gebastelt.
Usage: ./check_qnap <hostname> <community> <part> <warning> <critical>
Parts are:  cpu, diskusage, temp, hdstatus and volstatus (volstatus = Raid Info)
Example: ./check_qnap 127.0.0.1 public diskusage 80 95
Download: check_qnap

#!/bin/bash
if [ ! "$#" == "5" ]; then
echo -e "\nWarning: Wrong command line arguments. \nUsage: ./check_qnap <hostname> <community> <part> <warning> <critical>\n \nParts are:  cpu, diskusage, temp, hdstatus and volstatus (volstatus = Raid Info)\nExample: ./check_qnap 127.0.0.1 public diskusage 80 95\n" && exit "3"
