How do you add an entry to the Nagios Event Log?
I have an Event Handler script that creates tickets in Service Now and would like to record the details in the Event Log.

thanks.... Fred

I think adding a service comment would be the easiest way.

Look at the "Adding Comments Locally From Nagios Host" examples.

Otherwise you could just echo "xxxx" >> /usr/local/nagios/var/nagios.log but that doesn't feel nice.

Thanks Troy - I really wanted the message to appear in the Nagios Event Log as an "Information" entry. That way I can see the progress of a event from Soft to Hard, who was notified and when the event handler was triggered. This is the info needed for investigations/post-mortems.

Not sure where the details for the Event Log are stored - they look completely different to what is stored in /usr/local/nagios/var/nagios.log

As far as I understand, what appears in the Nagios XI Event Log is being pulled from a database.

When a command is submitted to the nagios command pipe it enters nagios and then the NDO2DB module stores it in the database (as well as being written to nagios.log). Hence simply echoing something into the nagios.log means it's not going to be detected by NDO2DB.

This page shows you all the external commands that can be submitted, hence I can't find a general "information" type of command.

I'll get the USA techs to follow up.

From one of our devs:

I would advise against editing the event log, since it's a copy of the nagios.log - plus there are set commands that add things to the log and it won't just show up properly elsewhere just by adding it into the DB... troy's suggestion for adding a comment is probably the best way to do it.

I tend to agree, adding a comment is the way to go. I can add in a feature request for the sort of functionality you are looking for, but I cannot guarantee it would make it in.

Thanks All - Since Global Host/Service Event Handler entries are in the Event Log, I would have expected (hoped) that the normal Host/Service Event handlers would also appear in the Event Log or we would have some mechanism to add this info to the event log so that we can display it in a Nagios screen when they get triggered . Not really wanting to give people server logins so they can trawl through a log file.

One thing to note is that you can set log_event_handlers=1 in your /usr/local/nagios/etc/nagios.cfg file if you just want to see if the event handler is being fired.

Brilliant - this is good enough for what I need
Thanks.... Fred

Great, are we okay to mark this as resolved and lock the topic?

yes - please close
