NRDP doesn't seem to work, and I don't know where to look...

[Johan159]

Hello,

I installed Nagios Log Server a couple days ago and am now trying to set up some alerting to my Nagios Core server. NRDP is already working properly there and is receiving messages from other sources.

I tried to configure a NRDP destination on Nagios Log Server, and associated alerts to it. I manually triggered some alerts but nothing has been received on my Nagios Core server.

And, it's ironic, but I can't find any logs about this action on the Nagios Log Server... Where should I check to see what's wrong?

Thanks in advance for your help!

Run a tcpdump on the Logserver machine then trigger some alerts to see if the traffic is even getting out:

Code: Select all

tcpdump dst host <Nagios Core server ip>

If it is, we might need to run a similar command on the Core server to see if it is getting in:

Code: Select all

tcpdump src host <Logserver ip>

If it is not I would suspect a firewall or other device between the two.

Thank you for your feedback.

I managed to find out what was wrong. It might be considered as a bug (if it is possible to reproduce it) that could be corrected. Here is what I did :

1) I created a NRDP destination called NAGIOS_HOSTNAME.
2) I associated this destination to several alerts
3) I deleted the NAGIOS_HOSTNAME NRDP destination, and recreated it under the same name.
4) The alerts were still pointing to "NAGIOS_HOSTNAME" but it seems that they were pointing to the first definition (which contained errors).
5) I recreated the alerts, ponting to NAGIOS_HOSTNAME, and everything then worked as expected.

That makes sense. They are tied to a unique ID, which after deleting one, you would need to re-select the "NRDP Server" for each of your alerts.
