Help with NRDS?

[jbennett]

I've finally been able to look into NRDS some.

It really looks like this might be the best option for us for SNMP checks, NRPE checks, and Traps all in one.

It will make pushing out the changes to all of the hosts a heck of a lot easier.

I suppose I can abandon this thread and start a new one for NRDS? It looks like the component was already installed on the old box and copied over when I moved to the new box.

When I click on the NRDS config manager, I see the following:

Code: Select all

You need to configure the NRDP server 
before you can create a NRDS config.

You must have the version 1.2 or greater of the NRDP Server before you can create a NRDS config.

Apparently, the NRDP server is already installed on this box, but I was getting an error that it wasn't the 1.2 version so I downloaded it and ran through the document here: http://assets.nagios.com/downloads/nrdp ... erview.pdf

I am able to input the token to test the nagios commands and the check data. I get an ok on the commands and the following on the check data:

Code: Select all

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<result>
<status>0</status>
<message>OK</message>
<meta>
<output>2 checks processed.</output>
</meta>
</result>

However, when I click back on the NRDS Config manager link, I get the following:

Code: Select all

You must have the version 1.2 or greater of the NRDP Server before you can create a NRDS config.

I'm guessing there's a better way to update NRDP?

[jbennett]

I just checked the /usr/local/nrdp/server/config.inc.php file to see if there might be something else I needed to configure and I came across this:

Code: Select all

///////// DONT MODIFY ANYTHING BELOW THIS LINE /////////

$cfg['product_name']='nrdp';
$cfg['product_version']='1.0'

Thinking that the file might have been old from the previous install, I downloaded NRDP again (http://assets.nagios.com/downloads/nrdp/nrdp.zip) and checked the config.inc.php file in there to see if it had a newer version.

It still lists 1.0 as the version in that file as well.

NRDS already installed

I had already tried removing the component and uploading it again. WHen I did this, I was presented with the instructions to follow on the Nagios server putty session, which I did. Now, when I go back to the manage components page, I only see the following. The instructions to complete the install are no longer there.

Code: Select all

NRDS Config Manager
This component allows administrators to manage their NRDS config files to be distributed to remote clients. 
Version: 1.2 Date: 02/27/2012 Author: Scott Wilkerson. Nagios Enterprises, LLC

For measure, I tried removing the component and uploading once more. Upon uploading again, I get the install instructions again:

I realize it tells me auth required, but then it tells me tat the server component installed successfully?

[scottwilkerson]

Ok, the component zip installed but we need to get the package through the proxy

Follow the info here to adjust your /etc/wgetrc proxy settings

Then run

Code: Select all

cd /usr/local/nagiosxi/html/includes/components/nrdsconfigmanager
rm -f installed.nrds
./install.sh

I tried this on our old server. I have more control over this old server and I can get out via proxy via CNTLM without having to submit a ticket to the server guys. If I can get it working here, I will have to submit a ticket to the server guys to have them open up the new server for the installs and I will have to provide them with step-by-step instructions.

Here is what I've been able to do so far on the old server:

Uploaded the nrdsconfigmanager.zip to the 'Manage Components' page and followed the resulting instructions:

Code: Select all

NRDS Server component installed sucessfully

I now have the NRDS Config Manager menu item under the CCM -> Monitoring Config section. I was able to copy the token that is provided here for use in the config.inc.php file for the NRDP server below.

Now to install & configure the NRDP server:

Now, when I go to the NRDP server page and test the checks with the token I entered into the config.inc.php page, I get OKs in return.

However, when I go back to the NRDS Config Manager page, I get the same error message:

Code: Select all

You must have the version 1.2 or greater of the NRDP Server before you can create a NRDS config.

When I check the bottom of the /usr/local/nrdp/server/config.inc.php file, I see the following again:

Code: Select all

///////// DONT MODIFY ANYTHING BELOW THIS LINE /////////

$cfg['product_name']='nrdp';
$cfg['product_version']='1.0'


?>

[scottwilkerson]

Uploaded the nrdsconfigmanager.zip to the 'Manage Components' page and followed the resulting instructions:

This looks good

Now to install & configure the NRDP server:

This is where you are going wrong... NRDP is already installed and when you do this you are rolling back to a previous version that doesn't include the NRDS addons.

To resolve the issue, run this

Code: Select all

cd /usr/local/nagiosxi/html/includes/components/nrdsconfigmanager
rm installed.nrds
./installnrds

[jbennett]

AH HA!

So then, the NRDS document doesn't even come into the picture in this instance?

This makes things a whole lot easier.

[jbennett]

Ok - I was able to get this configured and was able to go through the config manager and create a new config for a Linux machine using the provided sample config.

I then followed the instructions from the client install instructions as the document says:

So close, yet so far...

is cron running on this remote machine?

Do you see any errors, and can you see it running in the cron log
