Nagios Support Forum

We are monitoring hundreds of servers. in order to ease the deployment we are using nrds.
But WE HAVE A PROBLEM. NRDS client is a scheduled base vb script and some time it fails and stops sending data. And the services are in unknown state
Most of the time I just reinstall the client. But it's becoming annoying. Instead of nagios helping me I am chasing monitoring related issues.

Is there a way to fix this?
Or maybe there is a better simpler way to monitor 300 servers?

NRDS client is a scheduled base vb script and some time it fails and stops sending data.

Did you try to determine why this is happening, instead of reinstalling the client? Is there anything in your environment that prevents the scheduled jobs from running?

You can try the following - open the "Task Scheduler", select the NRDS task, click on the "Action" menu and go to "Properties". Under the "General" tab, select the "Run with highest privileges" checkbox, and click "OK".

Yes I tried in some cases the task wasnt running because of other task. which is understandable.
But in other cases the task would run but the client would just not send the data. The issues is as follows:
At firs at works fine but after some time it just stops sending data. in the scheduled task i see that i had run successfully but in the nagios log i dont see nothing. (I have to point out that it happens to only 5% of the servers most of them work just fine)
This is how the end of log file looks like:

as you can see the last entry is couple of weeks ago.....

What is the size of the "NRDS_Debug.log" on the Windows box and when was the last time it was modified?

its 84 KB it is constantly changes the last mod date. so now its today..... but i dont see any changes in the actual log

but i dont see any changes in the actual log

Do you mean you only see the "old" entries from a couple of weeks ago?

Double click on the scheduled task, go to the "Settings" tab, and see if the "Stop the task if it runs longer than" check-box is selected. I've seen cases when the task stops running after a certain period of time (1 day, 3 days, etc.).

yes

this box is cheked

Have you compared the configs from the Nagios XI server (Admin->NRDS Config Manager) and the Windows box (C:\Program Files\Nagios\NRDS_Win\config.ini)? Any inconsistencies (IP address, token, config name, etc.)?

The version is the same, everything else is ok. its not just this one server its about 10% of all my servers.

I tried using the NCPA client. The host appeared in the unconfigured objects but the never sent any data.

Did you configure the services after you saw it in unconfigured objects? No data will appe4ar until you run the items through the wizard. they appear in unconfigured objects if the XI server doesn't have the checks configured.

If it still appears in unconfigured objects, select the objects and click the blue arrow to configure them
