Try

 

define command {
        command_name                    check_s1
        command_line                    $USER1$/check_http -H

the nagios newb re: socket error

 

I haven't installed anything on the webservers (yet), but I do wish to
via snmp do load, cpu, etc. or if there is a better way like a client
daemon, feel free to let me know. I am still reading/understanding what
each is used for (service.cfg, commands.cfg, etc.) but I have the
following all for that check;

services.cfg
define service {
        service_description             check_s1
        use                             generic-service
        hostgroup_name                  s1_WebServers
        check_command                   check_s1!3!5
}

check_commands.cfg
define command {
        command_name                    check_s1
        command_line                    $USER1$/check_http -H
www.site1.com -w "$ARG1$" -c "$ARG2$"
}

command.cfg has;
command[check_s1]=/usr/local/groundwork/nagios/libexec/check_http -H
www.site1.com -I $HOSTADDRESS$

As for where the local command was run, yes it was local to the
groundwork (nagios) server from the following location;

root at groundwork:/usr/local/groundwork/nagios/libexec/check_http -H
www.site1.com -I 192.168.50.101
HTTP OK HTTP/1.1 200 OK - 14351 bytes in 0.249 seconds
|time=0.249456s;;;0.000000 size=14351B;;;0

I am not sure what the NRPE plugin is but just looking at the options,
it looks like it's run on the client as there is no spot for IP, when
run local it simply says connection refused by host for the site1.com
domain.

Thanks.

Hi,

 

Where did you define the check_s1 command? On which host? It looks like
an NRPE config so is this on one of the web servers or on your Nagios
host?

 

Where did you try running the command from the shell? On the Nagios host
or the web server?

 

Please show the command definition from Nagios for check_s1 as well.

 

Make sure that you've edited the correct NRPE config file, reloaded
nrped if you're not using inetd. To check that the check works from the
command line, run the check_nrpe command from Nagios, not check_http
from Nagios or the webserver.

 

Regards,

Martin Melin

	Hi all, well I am running GroundWork open source and really
happy with the layout, etc. and now comes the nagios things.  My goal is
to setup things neatly, organized and learn as I go rather than asking
stupid q's along the way.  So with that, the 1st task;
	
	I have 8 webservers all host numerous sites, a few host only
select.  So I have created some hostgroups, adding the servers that
belong to each, and wonderfully it works.  I can select a server, see
the group, click the group, see the servers (did I mention I'm good)  :)
	
	Anyway, I want to setup 2 seperate checks one for each website,
then associate them with the groups, so for example;
	ws1 (site1, site2)
	ws2 (site1)
	ws3 (site1, site2)
	ws4 (site2)
	
	Pretty simple.  So I copied the check_http command where I saw
it used and have the following;
	
	
command[check_http]=/usr/local/groundwork/nagios/libexec/check_http -H
$HOSTADDRESS$ -I $HOSTADDRESS$
	
command[check_s1]=/usr/local/groundwork/nagios/libexec/check_http -H
www.site1.com -I $HOSTADDRESS$
	
command[check_s2]=/usr/local/groundwork/nagios/libexec/check_http -H
www.site2.com -I $HOSTADDRESS$
	
	The services.cfg has the following (will only show 1 for space)
	
	define service {
	        service_description      check_s1
	        use                            generic-service
	        hostgroup_name         s1_WebServers
	        check_command        check_s1!3!5
	}
	
	Now after the above setup and a restart, I have happy to see the
check_s1 listed but it's showing critical with the following error;
	CRITICAL - Socket timeout after 10 seconds 
	
	At the command line check it does work;
	 ./check_http -H www.site1.com -I 192.168.50.101
	HTTP OK HTTP/1.1 200 OK - 14398 bytes in 0.090 seconds
|time=0.089949s;;;0.000000 size=14398B;;;0
	
	I am looking through where people are increasing the timeout,
but the response time is not even a second, so there must be something
else I am missing.  So I am looking forward to learning more, welcome
any ideas, suggestions, or anything else I should know about using
nagios under groundwork.
	
	This is running under ubuntu-8.10 server, Program Version:3.0.6,
let me know what else I can or need to provide on this.
