Monitoring service status

jimp

If you can run a command line check, use:

pfSsh.php playback svc status captiveportal

For example:

: pfSsh.php playback svc status captiveportal thiszone

Starting the pfSense developer shell....

Service captiveportal is running.

rct

Thanks for the reply!

I don't know why but if launch the command I don't have the status.

Example 1.

pfSsh.php playback svc status captiveportal cpzone

Starting the pfSense shell system...............

Attempting to issue status to captiveportal service...

Example 2.

pfSsh.php playback svc status squid

Starting the pfSense shell system...............

Attempting to issue status to squid service...

My pfSenses are 2.1.5 and the services are up.
I tried to shutdown a service but the answer is the same.
The script always exit with error code 0 (echo $?).

Any idea?

I've found that there is no "status" action in /etc/phpshellsessions/svc
Github shows that it has been introduced in 2.2 beta.

Looks like I will have to wait for us to upgrade to 2.2 or do a ugly patch to svc (it should work I think)…

Thank you for showing me the right file.

jimp

Yes, the status action only works on 2.2.

You could take /etc/phpshellsessions/svc from a 2.2 box and use it on 2.1.5 though, the only changes were in that one file and I believe all the necessary supporting functions were there as well. Worth a shot.

rct

Yes but i'm afraid it could break something for the next upgrade to 2.2.

jimp

overwriting that one file won't hurt anything.

rct

OK thank you

I have setup those checks with Nagios and NRPE.

If it can help someone :

Install NRPE via System>Packages
Download the zipfile (http://www.filedropper.com/checkpfsvc). It contains 2 files : "check_pfsvc" which is the nagios plugin used by nrpe to do the services check and "svc" which is a pfSense 2.2 version of the file /etc/phpshellsessions/svc
Transfer "check_pfsvc" in /usr/pbi/nrpe-amd64/libexec/nagios (it should be another location for 32b installations) and do a chmod 555 on it ; chown it to root and set the group to wheel
If your pfSense version is <2.2 backup your /etc/phpshellsessions/svc and replace with the file provided in the archive

After that configure NRPE as you need. See nrpev2.png to see how i've configured it.

Hello,

I'm back because I've upgraded to latest pfsense release and my script does not work through NRPE but it works from root account through SSH.
I've tried to port it to sh script but it does not work. The error I catch from the nrpe launch of my script is /usr/pbi/nrpe-amd64/local/libexec/nagios/check_pfsvc: /usr/local/sbin/pfSsh.php: not found

Does someone has an idea why it does not work anymore?

rct

No idea? I think it's a modification on rights or in the nrpe plugin but I can't find it.

I can't download the zipfile =(

that link redirects me to filedropper.com

It doesn't work anymore on pfSense 2.2.x and I can't find why. Sorry.

rocaembole

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

thanks, [hippie] i love you [/hippie]

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

rct

No problem! I hope it'll do the trick for you :)

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

}

rct

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
}
