28 Nov – 2 Dec reported from the OSMC while offering tips for windows monitoring without NSClient++, keeping an eye on DNS server activity and a Python solution to a Windows Vista UAC bug.

To begin, Birger saw the OSMC 2011 kick off, with an opening speech by Bernd where our new performance grapher, InGraph was also introduced. He then went off to Christoph Siess’ presentation, which gave a “Performance Comparison of Nagios Monitoring Solutions” (read Nagios, Icinga, Shinken, mod_gearman, Merlin). In short, he noted latency dramatically increases in Nagios 3.2.1 once a certain number of checks is exceeded. Nagios with mod_gearman and Shinken perform significantly better, while latency in Nagios, Icinga and Merlin were similar.

Ronny followed with a tool for statistical analysis of DNS servers. The DSC (DNS Statistics Collector) runs a collector on the server to record traffic flows in the form of a XML file every 60 seconds. This file is then converted by a presenter component for display in a CGI web interface. More information is available on the developer’s homepage.

Bernd then offered his impressions of the second OSMC day. After a big night atop the Nuremberg Christmas Market, almost all attendees made it to the conference rooms for two tracks of presentations on Nagios, Icinga with their related plugins and addons.

In between, Carsten offered an alternative to NSClient++ for windows monitoring – check_wmi_plus. As a plugin, check_wmi_plus offers agentless monitoring of a similar standard, implementing checks with performance data too. He noted that installation requires the WMI client for Linux, and gave some tips for configuring users and service monitoring in the command line with SubInACL. Documentation with more on useful checks is also within reach.

Also, Johannes shared a Python module for Windows Vista’s UAC, which he ported based on a suggested solution made by Aaron Margosis in his blog. Humbler.py resolves a problem similar to the LUA bug, where the user settings are at odds with the registered user.

Finally Pamela bid the OSMC 2011 farewell, thanking all participants, supporters and the Holiday Inn hotel for their contributions to a great event. She shared Jens-Christopf Brendel’s review in Admin Magazin and has since been busy filling the attendee area of the OSMC website with photos and presentation slides from the conference. The date for the next OSMC has been set for 17 – 18 October 2012, but before then, we hope to see you at our next event – the Open Source Data Center Conference on 25 – 26 April!
