_nowhere_ Today [Thruk][1] has released version 2.00 wich is a great milestone and a huge step forward. Instead of adding lots of things, we tried to remove unnecessary dependencies. Version 2.00 comes without the Catalyst framework and many performance improvements, especcially on larger setups.

One of the most often requested features is the possibility to place hosts, services and host/servicegroups on a geomap.
Now with release 1.88 Thruk made a major change in its panorama dashboard to support this kind of map too.

fritzdect200-smallIm Februar bestellt und in der letzten Mai-Woche eingetroffen. Die intelligenten Steckdosen von AVM scheinen heiss begehrt zu sein. Jedenfalls kann ich jetzt über meine FRITZ!BOX aufzeichnen, wieviel Strom gewisse Geräte momentan oder aber über einen langen Zeitraum verbrauchen.
Von Berufs wegen juckt's mich natürlich jedesmal in den Fingern, wenn irgendwo Messwerte anfallen. Mein Plugin check_nwc_health kann ja bereits CPU, Speicher und Interfaces einer FRITZ!BOX 7390 abfragen, also war klar, daß die Überwachung der FRITZ!DECT 200 bzw. des gemessenen Energieverbrauchs unbedingt dazugehört.

Die fünfte Ausgabe der ConSol Monitoring Minutes, die sich mit diesem Thema befasst, ist heute ebenfalls entstanden.

Soeben erschienen: die zweite Folge der ConSol Monitoring Minutes. Getreu unserem Motto “aus der Praxis für die Praxis” zeigen wir darin live, wie die Checks einer großen Nagios-Installation (hier: einer OMD-Site) mit Mod-Gearman an Worker delegiert werden können.

Beim “Schweizer Taschenmesser” OMD (erhältlich über das ConSol-Repository) ist Mod-Gearman bereits integriert.

Since Version 1.46 of Thruk the number of problems can be dynamically viewed in Thruks favicon. This is quite handy for creating a pinned app tab in Firefox.

Thruk uses the mod_fcgid apache module which makes Thruk start on the first request. The user then gets a “waiting” page till the fastcgi server has started. When using Thruk all the time, there is no reason to wait till someone makes the first request and you can just fire up the init script after apache starts.

In normal installations there is an rc script in /etc/init.d/thruk which fakes a request and makes the fastcgi server start.

 root@mo:~ #> /etc/init.d/thruk start
 Starting thruk.........(10492) OK

In OMD its even easier, latest snapshots have so called ‘init-hooks’ which are executed after the rc script. You
need to create two files in your site:

  • etc/init-hooks.d/apache-start-post
  • etc/init-hooks.d/apache-reload-post

One of them can be a symlink, because both files will have the same content:

 #!/bin/sh
 # check return code of apache start
 if [ $4 = 0 ]; then
   ./etc/init.d/thruk start
 fi

So when ever your apache starts / reloads, for example after logfile rotation, thruk will immediatly start too.

Every now and then some of our 7x24 hosts / services need a daily or weekly maintmode for regular restarts. Normally you would have to create 2 new timeperiods because you don’t want both hosts in a cluster to be restarted at the same time. This is not just way to much work, it also adds unnecessary complexity because
nobody can see the maintmode unless you look into the config files.

Thats where recurring downtimes will become handy and latest Thruk Version includes this new feature.

One of my bigger OMD installations consists of 13 sites. The visualization layer uses the Thruk interface. This alternative web ui can read data from multiple livestatus backends and display the host and service objects in one unified view. For this purpose i have one extra site called gui which only starts an apache process. I then point my browser to http://…./gui/thruk

The addresses of the livestatus backends have to be written into a config file, thruk_local.cfg. Now what if my list of 13 sites would be constantly changing? What if new OMD sites would be created, others deleted on a daily basis? I would have to edit the config file every time. With the new init-hook-feature, OMD will do this automatically for me.
