      No problem, i need it for a pfSense 2.1-RELEASE

      BTW: Anyone knows this package? https://exchange.nagios.org/directory/Plugins/Software/check_squid/details

      check_squid

      teorically it must be installed on Nagios Server (in my case, is a Ubuntu 14.04)

      idk if this works properly because i can't run it. It says

      Can't locate Nagios/Plugin.pm in @INC (you may need to install the Nagios::Plugin module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .)Can't locate Nagios/Plugin.pm in @INC (you may need to install the Nagios::Plugin module) (@INC contains: /etc/perl /usr/local/lib/perl/5.18.2 /usr/local/share/perl/5.18.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.18 /usr/share/perl/5.18 /usr/local/lib/site_perl .)

      I know this isn't a Nagios forum, but just for share the experience

            For your Nagios issue I think you miss the perl lib that has been written as a "template" for creating nagios plugins (https://exchange.nagios.org/directory/Plugins/*-Plugin-Development-Tools/Nagios-3A-3APlugin/details).

              i guess i need some more dependencies because when i run perl Makefile.PL this is what it shows:

              Warning: prerequisite Config::Tiny 0 not found.
Warning: prerequisite Math::Calc::Units 0 not found.
Warning: prerequisite Params::Validate 0 not found.
Writing Makefile for Nagios::Plugin
Writing MYMETA.yml and MYMETA.json

              i'll take a look to your file and follow your instructions to check squid & squidguard status for my pfsense

              Thank you for your attention

                  i've done all the configurations on pfsense side

                  now i'm on my Nagios Server and i don't know how to add this checks on my status monitor

                  here's my 'pfsense22.cg" file

                  
# A simple configuration file for monitoring the local host

# Custom services specific to this host are added here, but services

        }

# Define a service to check the number of currently running procs
# on the local machine.  Warning if > 250 processes, critical if

define service{

                    You can add the following to your file according you have setup a command named "check_squid_svc" in the NRPE package.

                    define service {
                            use                            generic-service
                            host_name                      pfsense22
                            service_description            Squid service
                            check_command                  check_nrpe!check_squid_svc
                    }

                      thanks!

                      it shows me an UNKNOWN state

send the plugin output and return code back to *this* plugin. This allows you
to execute plugins on remote hosts and 'fake' the results to make Nagios think
the plugin is being run locally.

                            Hi,

                            I'm trying to use your script on my pfsense 2.2.6.
                            In shell, it's working.
                            in nrpe, my remote server give me : Could not read output.
                            Another check on the pfsense using nrpe (check_load, …) are working as fine.

                            Any suggestions to fix this issue ?

                            Thanks,
                            Yannick

                              No sorry I've had the same problem when I have upgraded my pfSense and I haven't found a way to resolve this issue. :(

                                a short test with a bash script works as fine.
                                so it seems that the nagios account use by nrpe don't have rights to execute the php interpreter (/usr/local/bin/php).

                                  I agree it seems to be a security constraint somewhere but I don't know Freebsd and I haven't found why…

                                  If you try to launch
                                  su -m nagios -c "/usr/pbi/nrpe-amd64/libexec/nagios/check_pfsvc squid"
                                  it will work.

                                  But if you launch it throught the nrpe daemon it won't work.
                                  If edit the file to write dumb content (echo 'ok'; exit(0);) it will work.

                                  From my tests it's the call to '/usr/local/sbin/pfSsh.php' that is blocked.

                                  I've tried to launch /usr/local/sbin/pfSsh.php via a shell script configured as a nrpe command and it returns the error code 127 (http://tldp.org/LDP/abs/html/exitcodes.html ?).

                                  I don't know how to debug further...

                                    Yes, I have rewrite the script in shell and I have an error about "/usr/local/sbin/pfSsh.php not found".
                                    so the user nagios has no sufficent right to invoke this command.

                                      If you call your script
                                      sudo -m nagios -c "/path/to/your/script"
                                      I think it will work so it's more like if the nrpe service has not access to this file (may be it is jailed or there something else).

                                        I think nagios account is jailed.
