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:<o:p></o:p> <o:p></o:p> /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -p 5666 -n -c service_control -a "spooler" start<o:p></o:p> <o:p></o:p> 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.<o:p></o:p> <o:p></o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center> </div> From: Fernando Rocha [mailto:fernando.rocha@opservices.com.br] > Sent: Tuesday, July 15, 2008 4:38 AM > To: Jonathan Williams > Cc: Nagios Users Mailinglist > Subject: Re: [Nagios-users] Help - I am unable to get the NSClient++ to restart services<o:p></o:p> </div> <o:p></o:p> <div> <div> Jonathan, > > make sure that you have the xinetd installed and check if there is the following directory: > > [root@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@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!<o:p></o:p> <div> Fernando Rocha > OpServices Tecnologia da Informação<o:p></o:p> </div> > ----- Original Message ----- > From: "Jonathan Williams" <jonathan.williams@us.g4s.com> > To: "Fernando Rocha" <fernando.rocha@opservices.com.br> > Sent: Monday, July 14, 2008 7:07:57 PM (GMT-0300) Auto-Detected > Subject: RE: [Nagios-users] Help - I am unable to get the NSClient++ to restart services<o:p></o:p> <div> I was able to compile that without ssl and was able to install the pugin’s using the following<o:p></o:p> <o:p></o:p> Make install-plugin<o:p></o:p> Make install-daemon<o:p></o:p> Make install-daemon-config<o:p></o:p> <o:p></o:p> Those worked finer however the next step says:<o:p></o:p> <o:p></o:p> Install the NRPE daemon as a service under xinetd<o:p></o:p> Make install-xinetd<o:p></o:p> <o:p></o:p> I run that command and get:<o:p></o:p> root@nagiosserver:- /downloads/nrpe-2.8# cannot create regular file ‘/ect/xinetd.d/nrpe’ No such file or directory<o:p></o:p> make: *** [install-xinetd] Error 1<o:p></o:p> <o:p></o:p> Any thoughts??<o:p></o:p> <o:p></o:p> Thanks,<o:p></o:p> <o:p></o:p> Jon<o:p></o:p> <o:p></o:p> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center> </div> From: Fernando Rocha [mailto:fernando.rocha@opservices.com.br] > Sent: Monday, July 14, 2008 11:49 AM > To: Jonathan Williams > Subject: Re: [Nagios-users] Help - I am unable to get the NSClient++ to restart services<o:p></o:p> </div> <o:p></o:p> <div> Hi Jonathan! > > try to use the option --disable-ssl when you run ./configure<o:p></o:p> <div> Fernando Rocha > OpServices Tecnologia da Informação<o:p></o:p> </div> > > ----- Original Message ----- > From: "Jonathan Williams" <jonathan.williams@us.g4s.com> > To: "Paulo Ribas" <paulo.ribas@opservices.com.br> > Cc: nagios-users@lists.sourceforge.net > Sent: Monday, July 14, 2008 11:52:48 AM (GMT-0300) Auto-Detected > Subject: Re: [Nagios-users] Help - I am unable to get the NSClient++ to restart services<o:p></o:p> I am having a little trouble installing the NRPE 2.8 plug in Ubuntu.
