If John Dickinson can steal me a 30 minute block at the conference I'll probably be giving a talk about it, but we (Rackspace) started switching to Graphite back in December. We're basically just following the etsy cookbook to "graph all the things!".
We're using https://github.com/pandemicsyn/swift-informant to fire events to statsd. It takes care of answering questions like: How many Object GET 200's are we currently getting per second. How many container ops are we doing per second. What was the average request time of container HEAD's between 4-5PM last tuesday (which always seems to lead to the question of why are they so much slower today…oh look that node is having a weird hw issue)? Swift's also really good about dumping info to the error log. We convert the majority of those log lines to events thats get fired to statsd using https://github.com/pandemicsyn/statsdlog. That lets us track everything from container-replicator timeouts, auth service retries, to OSError's on the object servers (think we're tracking about 25-30 log line patterns at the moment). The last piece is just a hacked version of the swift-recon cli. It's what reports async-pending's, replication times, etc to graphite. Right now it gets tied together by tiny hackish Flask app that generates some tv dashboard's and will probably start doing the monitoring/alerting for the traffic prediction/confidence bands (experimenting with just doing it with an irc bot). -- Florian Hines | @pandemicsyn http://about.me/pandemicsyn On Wednesday, February 22, 2012 at 2:50 AM, Jasper Capel wrote: > I've uploaded the checks we use in production here at Spil Games to > https://github.com/spilgames/swift.
