Nagios Support Forum

I am facing this issue lately with one of the windows server. I tried reinstalling the client but no success. Any idea

CPU Usage Critical 8d 2h 26m 17s 5/5 2013-05-03 02:36:49 CRITICAL - Socket timeout after 10 seconds
Drive C: Disk Usage Critical 8d 2h 26m 5s 5/5 2013-05-03 02:36:49 CRITICAL - Socket timeout after 10 seconds
Logon Errors Critical 8d 2h 25m 53s 5/5 2013-05-03 02:38:37 CRITICAL - Socket timeout after 10 seconds
Memory Usage Critical 8d 2h 25m 41s 5/5 2013-05-03 02:39:16 CRITICAL - Socket timeout after 10 seconds

-----------------------------------------------
Here is the result of NMAP:
nmap <my ip> -p 12489

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-05-03 04:16 EDT
Interesting ports on <my ip>:
PORT STATE SERVICE
12489/tcp filtered unknown

Nmap finished: 1 IP address (1 host up) scanned in 0.333 seconds

Any idea to get away with this issue?

Thanks!

Filtered could mean that this port is not actually open, either via windows firewall, a proxy or transparent firewall, or that the service is not running. Can you verify that you have created a windows firewall rule to allow 12489 incoming? Also that there is not a firewall, or that it has ports opened to allow communication? If these are not the case, you can also use the -t flag with check_nt to extend the default timeout. -t 30 or -t 60 is fairly common.

@sreinhardt,

This didn't help. Any other suggestions?

Can you confirm that NSClient++ service is running on the remote system and there is NO firewall between these systems?

After comparing the results with 2 different server on different ip, finally figured out that this server hasn't been allowed port 12489 access from Nagios. After allowing the port, everything seems working.

Thanks all!
