Smokeping with Radius

Posted on by Posted in smokeping Leave a comment

So I had the need to monitor latency with Radius.

I added the necessary text into the Probe section and restarted Smokeping to see an error.

 

[....] Starting latency logger daemon: smokepingrequire Smokeping::probes::Radius failed: Can't locate Authen/Radius.pm in @INC (@INC contains: .. /usr/sbin/../lib /usr/sbin/../thirdparty/lib/perl5 /etc/perl /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14 /usr/share/perl/5.14 /usr/local/lib/site_perl .) at /usr/share/perl5/Smokeping/probes/Radius.pm line 19, <File> line 7.
BEGIN failed--compilation aborted at /usr/share/perl5/Smokeping/probes/Radius.pm line 19, <File> line 7.
Compilation failed in require at (eval 20) line 2, <File> line 7.

Just do apt-get install libauthen-radius-perl

There is also libnet-dns-perl, libnet-ldap-perl, and libnet-telnet-perl. These are useful for the other probe types.

Observium Professional edition – Adding smokeping intergration

Posted on by Posted in Observium, smokeping 7 Comments

Updated 11/12/2014 – Added smokeping cgi link at bottom of post.

Update 12/1/2014 – Adjusted smokeping cgi link at bottom due to Mike Hammett’s feedback. Updated from restart to reload in cron job.

Update 3/7/2014 – Added FastCGI info, Apache 2.4 info

 

Lets get smokeping integration going.

apt-get install smokeping libapache2-mod-fcgid

We are going to have to make some changes to both apache2 and Observium.

pico /opt/observium/config.php

Add:

//Smokeping
$config['smokeping']['dir']     = "/var/lib/smokeping";

Observium has scripts which generate the config. Lets run it and see what it generates.

php /opt/observium/scripts/generate-smokeping.php
*** Targets ***
probe = FPing
menu = Top
title = Network Latency Grapher
remark = Welcome to Observium SmokePing
+ Observium
menu = Observium
++ router
host = router

Ok, so lets actually put the config in place.

php /opt/observium/scripts/generate-smokeping.php > /etc/smokeping/config.d/Targets
/etc/init.d/smokeping reload

Let’s get Fast CGI going. Add this to /etc/smokeping/apache2.conf

<Location /smokeping/smokeping.cgi>
 SetHandler fcgid-script
</Location>

Enable CGI

a2enmod cgi

Restart apache

/etc/init.d/apache2 restart

Check back with Observium. Under the device,  a little paper airplane between “Ports” and “Inventory” labeled “Ping” should show up. This tab will now be populated with graphs generated by the same rrd files for which smokeping generates it’s graphs with. The graphs look very different and I’m personally disappointed that they don’t match. Fortunately, you can still get to the smokeping interface by visiting:

http://yourip/smokeping/smokeping.cgi

Be aware – If this server is going to be on the internet, you may want to protect smokeping’s pages using an apache realm. There is no other password protection that I’m aware of. You can remove the file from /etc/apache2/config.d/smokeping if you want to disable this.

If you want to generate the smokeping config file you can add the command to cron, but don’t generate it to often as it can lead to gaps in recorded information. Also, if smokeping doesn’t finish in it’s allotted 300 seconds, it can cause gaps in graphs as well.

I wanted a direct link to the actual smokeping page so I’ve been modifying /opt/observium/html/pages/device/latency.inc.php and adding the following line

echo('<a href=/smokeping/smokeping.cgi?target=Observium.' . str_replace(".","_",$device['hostname']) . ' target="_blank">' . $device['hostname'] . ' on Smokeping<a>' );

right after

echo('<table class="table table-striped">');
