NRDS

I have two nagios servers and I want one to send passive checks to the main one, so I used NRDS is this the right way to do it or is there a better way?
I have a few questions about NRDS that weren't answered in the video or pdf file.
Say I have already configured a Host, but I want to change the Hostname. How do I do that?
I tried to re-install by doing
Code: Select all
[root@csvmmon01 clients]# ./installnrds CSFlexdata01.tar.gz 1
nagios group already exists.
nagios user already exists.
Installing NRDS Client
Adding cron jobs for CSFlexdata01 at a 1 minute interval
Crontabs installed OK
Updating config and plugins
basename: extra operand `root'
Try `basename --help' for more information.

Try `basename --help' for more information.
Updated config to version 1.1 ERROR: plugin could not be retrieved from the NRDP server. Check NRDS plugin directory. ERROR: plugin could not be retrieved from the NRDP server. Check NRDS plugin directory. Updated 1 plugins
Installation complete
I thought it was weird that I got an error because I didn't the first time I did it. I looked it up and I ran this command and got this
Code: Select all
[root@csvmmon01 clients]# /usr/local/nrdp/clients/nrds/nrds_updater.sh
-bash: /usr/local/nrdp/clients/nrds/nrds_updater.sh: No such file or directory
what do I do about that?
Can I set up multiple nrds checks for different hosts on the back up server?

You can use inbound/outbound checks to do this.

For NRDS, you can change the hostname by editing the nagios users crontab on the remote system
you will see something like this
Code: Select all
*/5 * * * * /usr/local/nrdp/clients/nrds/nrds.pl -H 'OLD_HOST' 2>&1
change to
*/5 * * * * /usr/local/nrdp/clients/nrds/nrds.pl -H 'NEW_HOST' 2>&1

Just keep an eye on your Unconfigured Objects as I believe a new one will come in under your changed host name.

I actually did what you suggested before this I just didn't know if that was the proper way to do it, but now how do I remove NRDS from the sever since I should be using inbound and outbound transfers?
I have NRDP set up on the two servers but how do I configure services to be sent to the other server?

Did you enter the IP of the "main" Nagios XI server, that you will be sending checks to, and the authentication token in the "Target Hosts" section under the "Outbound Check Transfer Settings" ("NRDP" tab) on the remote box(es)?
If you no longer wish to use NRDS, you can stop clients from sending the checks to the main server, just by deleting the crontab enties on each remote box:
delete the entry, save and exit.

Yes, I entered in the correct information.
I found this file
http://assets.nagios.com/downloads/nrdp ... erview.pdf and was able to use this command on the slave sever
Code: Select all
[root@csvmmon01 clients]# /usr/bin/php /usr/local/nrdp/clients/send_nrdp.php --url=http://10.149.149.38/nrdp --token=v9hq7m04fob2 --host=somehost --service=someservice --state=0 --output="The service looks okay"
I received it in Unconfigured Objects. How do I configure hosts and services to send passive checks to the main server?

To configure forwarding:
Admin > Outbound Transfers > NRDP tab.
Then on the main server Admin > Inbound Transfers > NRDP tab, then they will populate in Admin > Unconfigured Objects.
Edit: NRDS to NRDP, reciting from memory has issues sometimes.

Do you mean NRDP tab?

I believe you are making this more difficult than it is... This functionality is provided in XI and I already sent you links to the two documents you need to use.
On the boxes that are sending traps, follow this document:
http://assets.nagios.com/downloads/nagi ... ith_XI.pdf
On the box, receiving traps, use this one:
http://assets.nagios.com/downloads/nagi ... ith_XI.pdf
Once, you see the checks in the "Unconfigured Objects" on the receiving box, select them all and click on the "Configure" action button.
