How to monitor kubernetes pod status with PRTG

Since there is no official kubernetes support by PRTG, I decided to create something fast and simple by my own. It took 10 minutes to write the script and configure PRTG sensor.

1. Create shell script

touch /var/prtg/scripts/podmon.sh

2. Add the content to the script

#!/bin/bash
serviceIsRunning=false
status=$(kubectl get pods |grep elasticsearch-master-0 |awk '{print $3}')
if [ "$status" == Running ]
then
serviceIsRunning=true
echo "0:200:$status"
fi
if [ $serviceIsRunning == false ]
then
echo "2:404:$status"
fi

3. Save the script and make it executable

chmod +x podmon.sh

Try to run it

./podmon.sh

0:200:Running

Go to the PRTG, and add the SSH Script sensor to the device

In the ‘Script’ field choose podmon.sh and SAVE

Normal response will be “200 Running”

! Make sure your PRTG Server has access to Asterisk Server, if not, add root username and password to the credentials in the BASIC DEVICE SETTINGS

And here’s the result:

I also have telegram notification alerts configured in PRTG, so I get the notifications in telegram group like this:
