Custom Nagios check works on CLI but not properly on web UI
Posted: Mon Apr 17, 2017 9:46 am
Hi all,
I am trying to create a custom nagios check plugin using Bash Script which reads data from a file and accordingly returns the exit code to the Nagios.
The Script works perfectly on the Nagios Command Line and returns the accurate output and the exit code.
Also, note that this plugin has been installed on the localhost itself and I am running the script from Nagios localhost CLI only.
The problem arrives when I run the script on the web UI, it always returns the exit code as 0 along with the following message:
I am guessing I am going somewhere wrong with file handling. Any help/leads would be really appreciated.

Code: Select all
#!/bin/bash
# script will check for the value of 'calculatedstatus' from the file
cat output | grep -A 1 -i "calculatedStatus" >> test.txt
if [ "$(cat test.txt | head -2 | tail -1 | cut -d " " -f2)" == "\"critical\"," ]; then
echo "exit 0"
exit 0
elif [ "$(cat test.txt | head -2 | tail -1 | cut -d " " -f2)" == "\"major\"," ]; then
echo "exit 1"
exit 1
elif [ "$(cat test.txt | head -2 | tail -1 | cut -d " " -f2)" == "\"minor\"," ]; then
echo "output is 2"
exit 2
elif [ "$(cat test.txt | head -2 | tail -1 | cut -d " " -f2)" == "\"operable\"," ]; then
echo "exit 3"
exit 3
fi
rm -rf test.txt

The problem arrives when I run the script on the web UI, it always returns the exit code as 0 along with the following message:
The plugin has been configured correctly as it gives the correct output on the UI for basic code such as "hello world" etc.(No output on stdout) stderr: cat: output: No such file or directory
I am guessing I am going somewhere wrong with file handling. Any help/leads would be really appreciated.
