New question #187391 on Graphite: https://answers.launchpad.net/graphite/+question/187391
I've just installed a basic deployment of Graphite 0.9.9 on an EC2 small instance running Ubuntu 11. Everything looks pretty up to date. It's running in a steady state; "committedPoints" shows an average reading of about 15K (that's per minute, I guess). 15 min Load avg is 0.23, IO is moderate showing an average of 15% utilization. Performance seems fine. But when I perform (what I perceive to be) a basic query, fetching 5 metrics from the last hour (120s resolution) it consistently takes >= 1000ms to fetch the data via HTTP on localhost. THe size of the data set returned is, obviously, quite small. Here's what my test URL looks like: http://statsd/render/?from=-1hour&rawData=true&target=7333.1&target=7333.2&target=7333.3&target=7333.4&target=7333.5 It's running on apache & mod_python. I see the same results when I use the standalone development server. This slowness strikes me as odd. Using whisper-fetch.py to read the relevant .wsp's does so in milliseconds (i.e. it appears to be in the kernel cache). Is this response time considered normal? Any suggestions on where I might look to troubleshoot this? -- You received this question notification because you are a member of graphite-dev, which is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
