Nagios Support Forum

I installed ncpa agent on a windows server 2012 R2 box and see the following messages in the ncpa_listener.log.
What could be the issue? The service starts but netstat -ab doesnt show the port number 5693.
IIS was running on that machine on port 80. Could that be an issue?

tried a different port number to start ncpa (15693) still no success. Same message as below.

Change the port # in the ncpa.cfg to the default one:
save and exit. Make sure your firewall is not blocking the port. Restart the service and try accessing the API in a browser:
Click on the API menu and check if you can see any disks listed. You can try:

Thanks for your prompt response
yes the port was default when i first tried it and firewall is off on my machine.
I see this error on a physical machine with WS2012R2. On a physical box with WS2012 it works. Makes me wonder whether 2012 r2 is supported or not by the NCPA agent

I'm not 100% sure if this would matter (I'm more of a Linux guy), but did you run the installer as Admin? It could be that due to a group policy setting the service cannot detect the disks.

I ran it as admin and the machine is not joined to the domain.
from a windows machine.. all i need is to collect Windows Event Logs, Check network utilization, CPU and Memory. Is there a way I can do it without Nagios agent on the client machine?
Can I do the same for a Linux machine also without an agent?

Absolutely, I'd recommend taking a look at the WMI Monitoring Wizard:

If you have any questions let us know!

Thanks i'll take a look. Does a agentless monitoring exist for Linux also?

i am bumping my post.

Thanks

That depends on what you mean by "agentless". If you mean exposing the internal metrics of a Linux machine with no prior configuration, then no this is not possible. *Something* needs to be running on the machine in order to query it, however it does not necessarily need to be a Nagios solution. NCPA does work on Linux, but as for a non-Nagios solution I am not aware of one that we would have a plugin for.

And as a side note for the future, we answer older posts before newer ones, so bumping your post, especially if you do it frequently, will possibly delay us getting to you.

Thanks for your reply. Sorry for bumping the post.

Basically I want to use Nagios XI for monitoring linux servers but not install any agent on it. Is that possible?


Secondly
I am in the evaluation phase of Nagios XI. Coming back to windows. Does it allow me to export all the Windows event logs? Currently I can see the windows events only when the system is up. I want to export logs even when the system is down.
Is that supported?
