NRDP

[kboeckx]

Hi,

I want to move from NSCA to NRDP. I found the NRDP_overview document http://assets.nagios.com/downloads/nagi ... erview.pdf but this is oviously not enough explenation to get it working.

Does anyone have a working NRDP configuration and is there a way to debug NRDP so I can learn what' going wrong ?

Thanks !

NRPD is PHP based, and runs from the public web server. Can you post some more information as to what you've done so far and where it appears to be failing?

I followed the installation procedure that I found in http://assets.nagios.com/downloads/nagi ... erview.pdf (except that I use "cp nrdp.conf /etc/apache2/conf.d" as the place for the webconfig)

Code: Select all

Download and unpack the NRDP package in the /tmp directory:
  cd /tmp
  wget http://assets.nagios.com/downloads/nrdp/nrdp.zip
  unzip nrdp.zip

Create an installation directory for NRDP:
  mkdir /usr/local/nrdp

Copy the NRDP files to the installation directory:
  cd nrdp
  cp -r * /usr/local/nrdp

Set permissions on NRDP directory/files:
  chown -R nagios.nagios /usr/local/nrdp

Edit the NRDP server config file:
  nano -w /usr/local/nrdp/server/config.inc.php

And add at least one token string to the $cfg['authorized_tokens'] variable. Example:
  $cfg['authorized_tokens'] = array(
  "asd7fjk3l34",
  "df23m7jadI34",
  );

Copy the Apache configuration file for NRDP. Optionally edit the /etc/httpd/conf.d/nrdp.conf file to configure settings as you need to
restrict access by address or enable SSL or basic authentication.
  cp nrdp.conf /etc/apache2/conf.d

Restart Apache
  /etc/init.d/httpd restart

The NRDP server has now been installed!

Then I opened the URL http://<ipaddress>/nrdp

I'm getting the screen like the attachement.
I'm able to use the first part of this interface (submit nagios command).
I'm not able to use the second part of the interface (with altered data that exists in the nagios config of course)

The next step is using the php client. I'm able to run this client with all the proper parameters but nagios is not getting anything ...

If I was able to debug the NRDP process, I would get some more details where it's going wrong. Is this possible ?

Thanks,
Kris

When you submit data with the "Submit Check Data" what is returned?

Do you already have the cfg for the host/service you are submitting?

I'm actually seeing the exact same behavior. I followed the document to the letter, and I'm testing with a brand new server and install of nagios core.

The "Submit Nagios Command" works perfectly, but the "Submit Check Data" it never seems to hit nagios.
The output on the webpage is:
<result>
<status>0</status>
<message>OK</message>
−
<meta>
<output>2 checks processed.</output>
</meta>
</result>

But monitoring the nagios log file and the nagios.debug file with it set to debug external commands nothing displays.

I do have the configurations for the host/services already defined.

Anyone have any suggestions, after lots of searching I find many people reporting the same problem but unfortunately no solutions.

Would I be better to use NSCA?

Got anything showing up in the apache log when these commands get submitted? I'm wondering if there's a PHP error somewhere.

Here are my access and html logs. I hadn't noticed the timezone error before, it doesn't occur when I use the "Submit Nagios Command" section:

I replaced my IP's with x's and y's.

I updated my php.ini file and have resolved that error, now the logs aren't showing anything when I submit but it's still not working.

Should I increase the logging level of httpd?

***Update*** I increased the log level to dubug, and still did not see any errors.

Looking around some more I see it's creating files in my /tmp directory:


-rw-r--r--. 1 apache apache 0 Apr 16 08:26 cy8wSSw.ok
-rwxrwx---. 1 apache nagcmd 238 Mar 30 16:41 cYNHIQs
-rw-r--r--. 1 apache apache 0 Mar 30 16:41 cYNHIQs.ok
-rwxrwx---. 1 apache nagcmd 238 Apr 10 08:41 czGG3iA
-rw-r--r--. 1 apache apache 0 Apr 10 08:41 czGG3iA.ok
-rwxrwx---. 1 apache nagcmd 236 Apr 17 13:09 czUKjvG
-rw-r--r--. 1 apache apache 0 Apr 17 13:09 czUKjvG.ok


It looks like when nrpd is done it creates the *.ok file so the nagios core can pick it up and process it.

This is either not happening or happening too fast for me to catch it with the nagios command
