Hi everyone,

In our company, we use nagios to do our monitoring of our servers. I have about 6 windows 2003 servers. I don't monitor very much on them, just ping, and hard drive space primarily.

The other nite, I get woken up at 330am, because nagios can't get anything from the hard drive monitors. But it can ping, because it doesn't need the windows client to do that.

So I get on the server, and nagios isn't running. Okay, maybe I didn't have the service on as automatic start. Nope, that looks fine. So I restart it.

I thought maybe I got stuck by the windows DEP protection. It was back to the original configuration, so I set it to not block nagios.

Okay, maybe a firewall got turned on or something. Nope that looks the same too.

Perhaps something is blocking port 5666 from listening. Nope that shows up when i do a netstat -an.

I reinstalled the nagios plugin, and made sure it was configured correctly. The service is running. The port is listening. Still, no monitoring from the hard drives.

I know we had a security update on the windows machines. And slowly thru the week, the rest of the machines all came down with the same problem.

We are currently running NSclient. I know its outdated, as there hasn't been an update since 2004. Is there any new updated solutions to this? I haven't found anything that works, installs easy, or does this job that I need.

Thanks,

Messing with it some more today, found this in the event viewer.

NSClient CollectData: Call to retrieve counter value for \Processor(_total)\% Processor Time failed, returning status code 2147485654.

Charlie,

I'm in the same situation with one of the couple of hundred Windows servers I'm monitoring with Cacti, using the Nagios agent for collection.
Judging by the date this thread was last updated, either you didn't get any response, or worked out what was happening...?
