During evaluation of the migration of a customer’s Nagios installation to the Shinken monitoring system, i encountered a strange problem. Reading the configuration from a few files (hosts.cfg, services.cfg, etc) took a reasonable amount of time. But as soon as i divided the configuration into lots of smaller files (one directory for each host with several services files within), it took nearly an hour. What happened?
Während des Bootens von Proliant-Servern wird eine umfangreiche Prüfung der verbauten Speichermodule durchgeführt. Entdeckt das Bios dabei Ungereimtheiten oder schadhafte DIMMs, so werden diese auskonfiguriert und der Bootvorgang fortgesetzt. Ob dies bei einem Server vorgekommen ist, zeigt ein Blick ins Integrated Management Log. Dort erscheint dann folgende Meldung:
Event: 26 Added: 03/08/2011 21:01 CAUTION: POST Messages - POST Error: 207-Memory initialization error on Processor 1 DIMM 6. The operating system may not have access to all of the memory installed in the system..
The developer team of OMD (Open Monitoring Distribution) released the version 0.50 today. This version contains bugfixes and lots of updated packages including Shinken, Thruk, PNP4Nagios, Mod-Gearman, check_oracle_health and check_mysql_health.
Jolokia and Jmx4Perl will go on tour this autumn. Roland Huss will talk about both projects in November at Devoxx, Antwerp, which is the biggest independent Java community conference in the world and at the Open Source Monitoring Conference, Nuremberg.
The summer break is over and Jolokia is one step closer to
1.0. Germans might reasonably argue, ‘ehm, what summer do you talk
about ?’ but at least 0.95 is now a fact and introduces two new
features. Very cool features, IMO.
Thruk 1.0.9 has just been released and contains a couple of cool new features. This version will also be in the next OMD release. Besides the release itself, new documentation about plugins and themes has been published.
