Nagios Support Forum

Hi,

We are running
NagiosXI 5.5.9 as a vmware image

We use nrpe for all our linux monitoring. Wanted to tryout ncpa.
https://assets.nagios.com/downloads/ncp ... g-NCPA.pdf
followed this document and installed NCPA on a SUSE 12 linux box
<hostname>:~ # rpm -qa | grep ncpa
ncpa-2.1.7-1.x86_64
<hostname>:~ #

Was able to use the NCPA wizard and configure the server for monitoring the basic default cpu, memory and all that and it works fine. but if i run the command from the NagiosXI server on command line it does not work.

Hello @sampaths,

Typically, if there's a timeout issue it is network related, especially since the commands are working from the Nagios web interface.

Try testing from the command line again but increase timeout value to more than 60 seconds, and add the verbose option to print additional error messages. Post any error messages to the thread.

Getting timeout even after increasing the time

Are you sure that you are using the same hostname in the command line as the one used in the GUI? Have you tried using an ip address instead of a hostname (FQDM)? Do you see any errors in the "ncpa_listener.log"?

Hi lmiltchev, sent a PM to you with the actual hostnames and stuff.

Replied via PM.

Thank you @lmiltchev for helping us fix the issue.

There was a proxy setup in the env, unsetting them fixed the issue.

unset {http,https,ftp}_proxy
unset {HTTP,HTTPS,FTP}_PROXY

Now it works in command line.

Hello @sampths,

Great. Thanks for the update and solution.

We'll go ahead and close this out but feel free to open another if you have any new questions.
