logstash queries graphed with graphite.

Operation: Decouple whisper from graphite.

Method: Create a graphite function that does a date histogram facet query against elasticsearch for a given query string for the time period viewed in the current graph.

Reason: graphite has some awesome math functions. Wouldn't it be cool if we could use those on logstash results?

The screenshot below is using logstash to watch the twitter stream of keywords "iphone" "apple" and "samsung" - then I graph them each, so we get an idea of popularity. As a bonus, I also do a movingAverage() on the iphone curve to show you why this is awesome.

This works under Ubuntu 10.10. I tried under 10.04 LTS but the Ubuntu templates are not there. Investigating.

[ Leaving this link here for reference in case I need to do apt-get upgrade. @ohloh recommends it

To make things easy have libvirt installed ie.

sudo apt-get install libvirt-bin

Otherwise you will need to set up bridges, iptables, dnsmasq.
