I have an OpenNMS system configured and up and running.
I have a few Linux (debian) servers and I need to monitor if a specific service is running on them. This must be done using only ssh access. No SNMP or agents. I must configure OpenNMS to log-in on these servers and check if this service is running.
I've read about Polling, but I haven't found instructions on how to configure OpenNMS to access a remote Linux computer and check if a service is running.
Ideally what I'm looking for is a way to specify in OpenNMS, an IP Address, username, password and the name of the process I want to monitor.
How can I do this?
