I would like to moniotor some services (ufw, duplicati, …) on linux (debian 10) servers. I have both check_mk and nagios plugins intalled but I don’t know how to monitor a service like NT services with NSClient (by using option to tell what service I want to check). I juste want to know if the service is up or down. The check_service could be fine but there is no -H option so I don’t know how to use it remotely.
As far as I know, all check_mk/nagios plugins on linux are for a specific app/service. Correct me if I’m wrong.
What can I use to do so and if there is doc where can I find it?
King regards and thanks for your help
It’s work great. Maybe few things: no need to put a clear password if you have done an ssh-copy-id with the monitored host before. And no need username if theire is a ssh_config file for librenms user. The script is more secure and shorter with this even if you have to do a bit of preconfiguration before
And exit code WARNING and UNKNOWN are not used
# Author: JP
# Check if service is running on remote machine using systemd
# Nagios exit codes
if [[ -z $HOSTNAME ]];
echo "Hostname is required"
elif [[ -z $SERVICE ]];
echo "Service is required"
ssh -T -q -o ConnectTimeout=10 $HOSTNAME "systemctl is-active $SERVICE" > /dev/null
if [[ $exitstatus -eq 0 ]];
echo "OK: Service $SERVICE is running."
echo "CRITICAL: Service $SERVICE is not running!"
