Sorry I haven't had time to come through with my offered scripts yet... I've got setups for exporting Ganglia XML to Nagios host/hostgroup configs, as well as doing host/service checks from the RRD data as well as directly from the XML ports. This is _very_handy_. I'm trying to get some other things out of the way and clean these for public consumption... It's actually that and the legal part (release) that's holding me up, sorry. I'll do this "real soon now".
As far as pulling data out of the RRD's for reporting, I've had to whip up some things in the past for dumping to CSV to be inclusive with other reports... Doing this for Cacti and Ganglia was quite the learning experience. What I mainly took out of it is a disdain for the format and tools, and new motivation to move to storing everything in a RDBMS and away from RRD entirely. :) /eli On 6/9/06 11:29 AM, "Stackpole, Chris" <[EMAIL PROTECTED]> wrote: > Good day, > > I have two topics I would like to gather opinions on from the Ganglia world. > > The first is that I have been looking at several different aspects of being > able to receive alerts when a node goes down.
