Host down due to plugins timing out

[Kaplan, Andrew H.]

Hi there --
 
The command_timeout option in the client's nrpe.cfg file is set to 60. The
syntax of the line is shown below:
 
command_timeout=60

The default timeout for nrpe is 10 seconds.    How long does your plugin take to
run?

Subject: [Nagios-users] Host down due to plugins timing out

 

Hi there -- 

I recently set up a new client to be monitored by our Nagios 3.1.2 server. The
client is running the CentOS 5.4 
operating system, and it has version 2.6 of NRPE as well as version 2.12 of the
plugins installed on it. I made 
sure to deactivate the firewall on the system, disable the SELinux option, and
also modified the /etc/services 
file to include port 5666 with udp and tcp. 

The problem that I am having is that even though everything appears to be
running properly, the requests that 
are sent from the Nagios server to the client are timing out, with the result
being the client appearing as down. 
The client has the nrpe program running with the following configuration: 

/usr/local/nrpe/bin/nrpe -n -c /usr/local/nrpe/etc/nrpe.cfg -d 

I verified the plugins are working on the client, and also confirmed there are
no other clients being reported as 
down. The configuration that I described is not unique to this client. This same
setup is working for other clients 
that are monitored by the server. 

Does anyone have any idea as to why this is occurring, and what I can do to
correct it? Thanks.
