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

Code: Select all

tail -f /var/log/cron

Just to verify, from /etc/services:

www-http         80/tcp    # World Wide Web HTTP
www-http         80/udp    # World Wide Web HTTP
Also, I noticed that I don't have the /usr/local/nrdp/plugins folder on this machine. I do have the /usr/local/nrdp/clients folder though.

Does this help?

This all looks correct, can you run the following from the command line

Code: Select all

/usr/local/nrdp/clients/nrds/nrds.pl -H testlane2

this is normal, the plugins are placed in /usr/local/nagios/libexec

When I go to the libexec folder, I see that the plug-ins being called are in nagios:nagios instead of all of the others which are root:root. I imagine this is correct?

Would it be possible for you to zip up and attach the /usr/local/nrdp/clients/send_nrdp.sh off of the remote system

Thanks

Can I have you replace your send_nrdp.sh with the one in this zip file

and then run the following again

Code: Select all

/usr/local/nrdp/clients/nrds/nrds.pl -H testlane2
If all goes well, lets also place this in the same path on your XI server any it will be used to build installers in the future

I copied over the file and adjusted permissions to match the previous version of the file. I have not copied over to the Nagios server just yet.

When I ran it, I see the same results:

Also, just to be sure the file I uploaded was different, I diffed them and see the change made.

You did overwrite the current file right? because the output you are showing makes me believe that /usr/local/nrdp/clients/send_nrdp.sh is still the old file...

*sigh* I see what I did. I've fixed it now.

New output:

Code: Select all

testlane2:/usr/local/nrdp/clients # /usr/local/nrdp/clients/nrds/nrds.pl -H testlane2
ERROR: STDIN must be either 3 or 4 fields long, I found 2
Sent 5 checks to http://xxx.xxx.xxx.xxx/nrdp/
When I check Nagios though, I don't see any unconfigured objects. When I search for the hostname used in the command, I don't find the information I'm expecting. I only show a single service and it's an SSH check that's been configured to run from the Nagios box for some time now.

This is better.

I assume http://xxx.xxx.xxx.xxx/nrdp/ is you XI server...

Also, by any chance have you implimented a RAMDisk on the XI server?

If so you will need to be sure you have your correct check_results_dir in
/usr/local/nrdp/server/config.inc.php

change

Code: Select all

$cfg["check_results_dir"]="/usr/local/nagios/var/spool/checkresults";
To something like this

Code: Select all

$cfg["check_results_dir"]="/var/nagiosramdisk/spool/checkresults";
Finally, you also are getting this

Code: Select all

ERROR: STDIN must be either 3 or 4 fields long, I found 2
which leads me to believe one of the commands is not quite right

YES! I had changed this initially when looking at the config file, but that would have been overwritten when I finally installed it correctly instead of how I was doing it. I've changed this now. Do I need to restart the NRDP server somehow?

I have only used the standard checks that are provided when you go to create a config initially since I wanted to just test this out first. These are the commands that you are referencing, correct?

Code: Select all

command[__HOST__]=/usr/local/nagios/libexec/check_ping -H localhost -w 200.0,40% -c 400.0,80% -p 1
command[Check Users]=/usr/local/nagios/libexec/check_users -w 5 -c 10 
command[Check Load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[Check Disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
command[Check Zombie Procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[Check Total Procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
