icinga2-keepalived is an icinga2 plugin to remotely check the status of keepalived instances.
For the plugin to function correctly you have to add a notification script to the keepalived.conf for each instance that you want to monitor.
-> keepalived_notify.sh
Add the script itself.
-> keepalived_notify.sh
Add the check plugin itself.
-> check_keepalived.conf
Add the service definition.
-> by_ssh_keepalived.conf
Add the command definition.
-> check_by_ssh_keepalived.conf
Restart icinga2 and check for errors.
I'm monitoring remote via ssh. If you need to monitor one instance locally, you need to define a local command and service. If I ever need to monitor one instance locally, I'll ad the command and script... or if I have some time left ;)
