CentOS - Feb 2009 - Nagios: Error: Service check command ... not defined anywhere!

Hello CentOS users,

I have problems posting the question below
to the Nagios mailing list (my subscription is
not accepted for some reason). Has anybody
of you already had this probably frequent
problem with Nagios in CentOS? I can''t use
check_squid from command-plugins.cfg (s. below)

Thank you for any hints
Alex

Dear Nagios users,

I''m using:

# cat /etc/*release
CentOS release 5.2 (Final) <-- compatible to RHEL 5.2

# rpm -qa|grep nagios
nagios-3.0.6-1.el5.rf
nagios-plugins-1.4.13-1.el5.rf

and have successfully added monitoring
of 20 other Linux-servers by replicating the
entries from /etc/nagios/objects/localhost.cfg

But now I''m trying to add 2 more things:

1) monitoring Squid
2) monitoring Apache at ports 8080 and 8090

I have found the following 3 lines:

command[check_http]=/usr/lib/nagios/plugins/check_http -H
$HOSTADDRESS$ -I $HOSTADDRESS$
command[check_http2]=/usr/lib/nagios/plugins/check_http -H $ARG1$ -I
$HOSTADDRESS$ -w $ARG2$ -c $ARG3$
.......
command[check_squid]=/usr/lib/nagios/plugins/check_http -H
$HOSTADDRESS$ -p $ARG1$  -u $ARG2$  -e ''HTTP/1.0 200 OK''

in the file /etc/nagios/command-plugins.cfg
and have added 1 more line:

command[check_http3]=/usr/lib/nagios/plugins/check_http -p $ARG1$ -I
$HOSTADDRESS$

(after reading "check_http --help").

In my config files I''ve added:

define host{
       use                     linux-server
       host_name               ablpdm01
       alias                   ablpdm01
       address                 10.121.42.100
       }
define service{
       use                             local-service
       host_name                       ablpdm01
       service_description             HTTP
       check_command                   check_http3!8090
       notifications_enabled           0
       }
..........
define host{
       use                     linux-server
       host_name               ablprx01
       alias                   ablprx01
       address                 10.121.42.32
       }
define service{
       use                             local-service
       host_name                       ablprx01
       service_description             Proxy
       check_command                   check_squid!8080
       }

Unfortunately I get errors now:

    Check your configuration file(s) to ensure that they contain valid
    directives and data defintions.  If you are upgrading from a previous
    version of Nagios, you should be aware that some variables/definitions
    may have been removed or modified in this version.  Make sure to read
    the HTML documentation regarding the config files, as well as the
    ''Whats New'' section to find out what has changed.

Does anybody have an idea what''s wrong?

Isn''t adding command[check_XXX]=YYY
to command-plugins.cfg enough?

I''m especially perplexed by check_squid being
not found even though it''s there from the start

Thank you
Alex

You should complain to the administrators of that mailing-list.

I still think my question isn''t offtopic here -
seeing how people discuss procmail/logrotate/etc.

Still using 2.x here but, isn''t there a commands.cfg file with some
check_http definition?
In doubt, take a working check_xyz and grep it in all the conf files and see if
you missed any...

thanks - yes, I always "grep -ri" for commands.

That is what perplexes me - the file

  # rpm -qf /etc/nagios/command-plugins.cfg
  nagios-plugins-1.4.13-1.el5.rf

contains both check_http and (few lines below) check_squid:

  # grep check_http /etc/nagios/command-plugins.cfg
  command[check_http]=/usr/lib/nagios/plugins/check_http -H
$HOSTADDRESS$ -I $HOSTADDRESS$
  command[check_http2]=/usr/lib/nagios/plugins/check_http -H $ARG1$ -I
  $HOSTADDRESS$ -w $ARG2$ -c $ARG3$
  command[check_squid]=/usr/lib/nagios/plugins/check_http -H
$HOSTADDRESS$ -p $ARG1$  -u $ARG2$  -e ''HTTP/1.0 200 OK''

And still I can use check_http, but can''t use check_squid:

  Error: Service check command ''check_squid'' specified in
service
  ''Proxy'' for host ''ablprx01'' not defined
anywhere!

Alex

What I meant was that there should also be a definition in the commands.cfg file
(if it is like 2.x)...

# grep check_http *
command-plugins.cfg:command[check_http]=/usr/lib/nagios/plugins/check_http -H
$HOSTADDRESS$ -I $HOSTADDRESS$
command-plugins.cfg:command[check_http2]=/usr/lib/nagios/plugins/check_http -H
$ARG1$ -I $HOSTADDRESS$ -w $ARG2$ -c $ARG3$
command-plugins.cfg:# Using check_http will allow verification of authenticated
proxies
command-plugins.cfg:command[check_squid]=/usr/lib/nagios/plugins/check_http -H
$HOSTADDRESS$ -p $ARG1$  -u $ARG2$  -e ''HTTP/1.0 200 OK''
commands.cfg:# ''check_http'' command definition
commands.cfg:        command_name    check_http
commands.cfg:        command_line    $USER1$/check_http -H $HOSTADDRESS$
commands.cfg:                command_line    $USER1$/check_http -H $ARG1$ -u
$ARG2$

Allright - that was it:

I should have added the commands
to the /etc/nagios/objects/commands.cfg
and not to the  /etc/nagios/command-plugins.cfg

Thanks

Well, you can include those, too (I think in nagios.cfg).

I had (like you) assumed, you already included that file.
Always check if the file you use is actually included in the
main-configuration...

unfortunately you can''t put
   cfg_file=/etc/nagios/objects/commands.cfg
into /etc/nagios/nagios.cfg -
it will bail out with an error message.

IMHO it''s a bug in nagios-plugins-1.4.13-1.el5.rf

I think he was just referring to your nagios mailing list problems...
