OK.. I am getting somewhere now.  I manually ran this command from the Nagios server terminal:

 

/usr/local/nagios/libexec/check_nrpe -H 10.10.113.51 -p 5666 -n -c service_control -a "spooler" start

 

And it worked!!  Meaning the OpMonagent works!  Now I jst need to find out why it will not work as an event_handler like so:

 

Define service{

      Use                     generic service

      Host_name               jwilliamspc

      Service_description     PrintSpooler

      Check_command           check_nt!SERVICESTATE!-d SHOWALL -l Spooler

      Event_handler           restart_Spooler

      }

 

define command{

command_name         restart-Spooler

command_line         PATH/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c service_control -a "Spooler" start

OK.  OpMon is running on the test server and my define_command for spooler restart reads exactly as you posted, still no service restart.  I am still missing something.  I am not sure if I need to edit anything in the OpMonagent.ini or service_control.cmd.

Jonathan,

The client installed on the host doesn't matter if both of them have support to nrpe. They will have a configuration file where you'll define the commands to run over check_nrpe.

NSClient++ uses NSC.ini
OpMonAgent uses opmonagent.ini

But to make it easy, the OpMonAgent has a command to restart services built-in his configuration file.

So, if you have the OpMonAgent running on host, you just need run the following command from your nagios server:

/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c service_control -a "spooler" start

But, if you are using NSClient++ you need define a command into the configuration file first, then you'll use this command in the check_nrpe.

Subject: RE: [Nagios-users] Help - I am unable to get the NSClient++ to restart services

I feel like I am back at square one.  It seems like a simple task to get Nagios to restart a service.  I have NRPE now running on the server under xinedt, and switched the client back to NSClient++ from OpMon Agent.  Both support NRPE.  I am not sure if I am supposed to get a service restarted with a NRPE_Check command like:

 

/usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c service_control -a "spooler" start

      

Or am is supposed to create scripts on the host that will restart a service like a .bat file with a "net start spooler" command and than get an event_handler set up to call that script.  It seems there are different ways to do it and I am being pulled both directions.  I am new to Nagios as well as Linux and have been able to scrap my way thus far while learning a lot about both, but am about ready to call it quits.  I was pointed to the NakedNuns website to the section on CheckExternalScripts, but honestly could not make much sense of it.

Jonathan,

make sure that you have the xinetd installed and check if there is the following directory:

[root at fernando ~]# ls /etc/xinetd.d/
chargen-dgram   daytime-dgram   discard-dgram   echo-dgram   eklogin       gssftp  krb5-telnet  ktalk  rsync          time-dgram
chargen-stream  daytime-stream  discard-stream  echo-stream  ekrb5-telnet  klogin  kshell       nrpe   tcpmux-server  time-stream

if you don't have that, try to install by apt-get!

and then, run the command again

Make install-xinetd

or you can install just writing a file like this:
[root at fernando ~]# cat /etc/xinetd.d/nrpe 
service nrpe
{
        flags = REUSE
        socket_type = stream
        wait = no
        only_from = 127.0.0.1 (PUT YOURS NARIOS SERVER'S IPS HERE)
        user = nagios (PUT THE NAGIOS USER HERE)
        server = /usr/local/nagios/libexec/nrpe (THE NRPE SERVER)
        server_args = -c /usr/local/nagios/libexec/nrpe.cfg --inetd (THE NRPE CONFIG FILE)
        log_on_failure += USERID
        disable = no
}

and then restart xinetd!

I was able to compile that without ssl and was able to install the pugin's using the following

 

Make install-plugin

Make install-daemon

Make install-daemon-config

 

Those worked finer however the next step says:

 

Install the NRPE daemon as a service under xinetd

Make install-xinetd

 

I run that command and get:

root at nagiosserver:- /downloads/nrpe-2.8# cannot create regular file '/ect/xinetd.d/nrpe' No such file or directory

make: *** [install-xinetd] Error 1

 

Any thoughts??

 

Thanks,

 

Jon

Hi Jonathan!

try to use the option --disable-ssl when you run ./configure

I am having a little trouble installing the NRPE 2.8 plug in Ubuntu.  I am able to extract the source code tarball and than I am having issues after that.  Per the instructions I am trying to compile the NRPE add-on by running

 

./configure

make all

 

After I type ./configure I get a message at the end of the compile job saying "configuration error: Cannot find ssl libraries.  Than if I try to go further by installing the plugins by typing make all or the individual make install-pluggin I get an error saying ** No rule to make target 'all'.  Stop.

I found the NRPE add-on (not plug-in) so I will download and install that.  I'll let you know if I run into anything.  You have been more than helpful.

 

Thanks,

 

Jon

check_nrpe is part of the package nrpe, if you use ubuntu, I believe that only an "apt-get install nrpe" solve your problem.

OK.. I do not have check_nrpe so apparently I need to download that plug-in on by Ubuntu box.

The commando must be:

define command{

command_name         restart-Spooler

command_line         PATH/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c service_control -a "Spooler" start
