Toward a Graphing Solution

Generaldatalogginggraphinggraphsgraphiterrdtool

For a project that we're too engaged with, students and I are exploring graphing server solutions. We started with rrdtool and quickly found cacti. But a student pointed us toward graphite, and I really didn't want to rediscover how to install every time we wanted to test it. So I've scripted a solution. I suppose they could be build notes toward a TKLPatch. Script on next post.

Graphite docs are here: http://graphite.readthedocs.org/en/0.9.10/.

We like: the API (nicely documented); the RRD alternative is nice and seems very quick and efficient.

Shouldn't matter I don't reckon

I had a quick glance over it and not that I'm any expert in these things but I didn't see anything glaringly Ubuntu specific. If I were you I'd give it a go and see what happens. If it doenss't work then share the errors/log messages and I'm happy to try to help work it out (as time permits at this crazy time of year...)

I think a daemon is needed for started carbon-cache.py

Draft conf script for Graphite

Reply 4

Draft conf script for potential TKLpatch - I can't figure out how to eliminate the interaction it wants when syncing db (typical of django apps?). Any ideas (http://stackoverflow.com/questions/1466827/automatically-create-an-admin...)? Also, this configures Graphite vhost to listen on 8080 with the assumption that people might like to use 80 for other things. Intended to be a patch applied to Core. Here's the script:

#!/bin/bash -ex
