Nagios Event Broker: event_broker_options
The Nagios Event Broker (NEB) API is very powerful. A large amount of different events in the Nagios Core can be hooked using the NEB modules which are connected to the API. With that many events and type of events there might be a big overhead cause particular modules only need a little group of those events.
There is a default way to control which type of events are forwarded to the NEB modules. The option is called event_broker_options and located in the Nagios configuration file (nagios.cfg).

BlackGlass: My new MediaPortal Skin
Blackglass is the name of the current MediaPortal Skin I use since several months now.
It was important to me to have a well designed and clear look and feel. Since i still use a two screen setup another important argument to choose Blackglass as Mediaportal skin was that it can widely be used with a Touchscreen. The basic home screen (main menu) is the best I can expect for touchscreens.

Thruk – A MKLivestatus webinterface
Thruk is a Webinterface for Nagios. The Nagios Webinterface called Thruk is the second Nagios Addon based on MKLivestatus. You will ask “Why yet another webinterface?”. The difference to all the other new Nagios Webinterfaces is in the focuses and goals of Thruk.
The Thruk Webinterface for Nagios has been created to get a more flexibile and faster Webinterface than the current CGI based Nagios Webinterface. Thruk can combine the status information of several Nagios Servers using them as multiple backends. This is possible when using MKLivestatus with a TCP socket to make it reachable from the Network.

ICINGA
Just one year ago this topic would be totally senseless. But different things happened with the Nagios project that it was just a question of time that a fork of Nagios would become reality.
I wrote some words about ICINGA, the Nagios fork, some time ago so I don’t want to repeat these words. But I [...]
