Hi List! We hacked an Icinga module to transfer our performance data into a Cassandra instance. We use an off-the-shelf message queue (0mq) to get the data there. Anybody interested in this solution? I could prepare a release during the weekend.
When looking at an rrd based solution (which we're using now), the deficits are: - changing data retention on the fly is not easily possible - upon a change in the data sources for a check, pnp4nagios will silently stop updating the rrd - in case the database can't keep up with the data written, icinga will not go into coma (happened with our old nagios) We fixed these and got the following advantages for free: - writes to Cassandra are *way* faster than writes to mysql - on the other hand if you're really trying to break your equipment, data will be dropped from the message queue (without stopping Icinga) but can in theory be cached on disk What we're presently planning: - connecting multiple icinga instances: use the message queue over slow links with disk backup, in case the link failes - rewrite check names on the message queue level, to connect various customers to our nagios instance, without allowing them to rewrite our checks (as nsca does) - extends the web interface and the Cassandra writer as to support a limited form of real time analytics for performance data Regards, Mark akquinet outsourcing gem.

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2d-c2 _______________________________________________ icinga-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/icinga-users
