We are back again. The ConSol posse enters Devoxx again and will posts some expressions from this largest independent Java conference. Roughly 3500 attendees transform Antwerp into Java’s epicenter for one week.

Business Prozesse in Nagios zu modellieren gehört zu den beinahe täglich anstehenden Aufgaben beim Thema Monitoring. Die neueste
Thruk Version (v1.78) bringt nun ein Business Prozess Addon mit dem sich Prozesse einfach per Gui modellieren lassen.
Tomorrow, I’ll be speaking on Infinispan at the JBoss One Day Talk 2013.
Slides can be found here: http://rawgithub.com/ConSol/reveal.js/2013-jbossOneDayTalk/index.html.
See you tomorrow!

Lange hat’s gedauert, aber seit heute kann man sich das Debian-Paket für OMD-1.00 vom ConSol-Labs-Repository herunterladen.
root@raspberrypi:~# apt-get install omd-1.00
Die Maschinen unserer Kunden, auf denen wir uns tagtäglich bewegen und Monitoring-Systeme betreiben, haben üblicherweise CPUs und Gigabytes im zweistelligen Bereich. Da wird es schon zur Geduldsprobe, wenn ein Build auf dem Raspberry Pi den halben Tag braucht. Ein ARM11 ist eben kein Xeon und SD ist nicht SSD.
Der eine oder andere check_nwc_health-Anwender dürfte --mode walk schon kennen. Damit kann man sich eine Liste von snmpwalk-Anweisungen ausgeben lassen, deren Resultat mir beim Debugging hilft.

Infinispan is included in the JBoss AS 7 distribution as the default second level cache for Hibernate.
For my presentation on the JBoss One Day Talk 2013,
I was looking for the most simple example to be used in a demo.
This post shows how to get Infinispan Hibernate 2nd Level Caching up and running in five minutes.
It should also work with the upcoming WildFly Application Server.

Changing major releases on linux is always a risk, but Debian / Ubuntu dist-upgrades really worked fine the last years. If you are using OMD (Open Monitoring Distribution) for Nagios/Icinga/Shinken, then the release-update would disabled 3rd party repositorys and therefore remove your OMD installations during the update. This is usually not what you want, but with a small trick, updates work smoothly.
Distributed caches have evolved into an independent branch of Big Data solutions: When it comes to fast read and write access, distributed caches are the solution of choice.
Dr. Fabian Stäber gave a talk a JayDay 2013 where he introduced and compared the leading distributed cache implementations:
Based on a simple example application, the basic functionality is presented, and the specific strengths and weaknesses of the different cache architectures are highlighted and compared.
The results of this ‘shootout’ and an executive summary can be found here at /java-caches and the example application is available from GitHub.

The developer team of OMD (Open Monitoring Distribution) released the version 1.00 today. Three years after the project started we decided it was time to show that OMD is no longer under development but is a mature, proven product.
This version contains lots of updated packages including Nagios 3.5.0, Shinken 1.4, Multisite 1.2.2p2, Thruk 1.72, PNP4Nagios 0.6.21, NagVis 1.7.1, check_mk 1.2.2p2 and many more.
Using the OMD Repository installation is as simple as a apt-get install omd. If you have an rpm-based system, it's as simple as yum install omd or zypper install omd.
For those who weren't using OMD yet, now there is no more reason to hesitate.
