nrdp and vmw_sender

[lkrzeminski]

Hello,

I am having a problem with NRDP with Nagios and just thought some of you guys have more experience and can help me out.

We want to monitor alerts from the Vcentre. I already found a plugin that runs on the vcentre and sends data to nrdp. Everything seems to be working ok but nrdp is not sending data over to nagios. How do I get those alerts in the nagios itself ? Do I need to set up specific checks for that or is nrdp supposed to automatically inject them to the nagios i.e. Cpu usage on the ESXi host. Sending commands from nrdp gui seems to be working fine. I can see them in the nagios log. I am not entirely clear how it works so if anyone can help I will really appreciate.

Thank you.

How did you install NRDP on that server? Did you point it's data to your nagios xi server and supply a valid token? This document should be able to get you off the ground and on the right path:

Hello Slansing

We've got nagios core and I followed this doc http://assets.nagios.com/downloads/nrdp ... erview.pdf to install NRDP.

Can you share the following file from the remote NRDP system? You can remove sensitive information:

/usr/local/nrdp/server/config.inc.php

It looks like you did not finish the documentation you cited, I'd start at the top of page two and work your way down. I'm not sure what was missed but it's good to double check, including adding a token:

http://assets.nagios.com/downloads/nrdp ... erview.pdf

[lkrzeminski]

I went thrugh that again and I am confident everything has been added. "OURTOKEN" in the config file is the token we used. I can successfully send requests from NRDP WebGUI and they do appear in the nagios.log.

It looks like you were running those commands from the nagios server as your terminal shows, you need to install NRDS on the system you intend to use that plugin on, not the Nagios server. As NRDS is a passive agent it must be placed at the location you would like to send data from.

[lkrzeminski]

I am using plugin - http://exchange.nagios.org/directory/Tu ... os/details

I've been talking to developer and he said nrdp need to be installed on the nagios. Plugin sends data to nrdp just fine, I don't seem to be able to get that data into nagios.

Many thanks for all your help.

If the plugin sends back to nrdp reciever on the nagios server and you seem to be seeing them in the logs, is the hostname being sent the same as the hostname for the nagios object you have a passive nrdp check setup for? The service name must also match.
