This is being used for some\nexperimentation into whether we can dump all of the timeseries data from\na baseline run of a test and then compare that against a new run to look\nfor anomalies or unexpected behavior.\n\nThere are currently 421 metrics captured for a single server containing\na single store. Samples are taken every 10s which translates into 2.3\nMiB of data per server per hour or 55.5 MiB per server per day. The\nresulting text output is slightly larger, but compresses in excess of\n10:1. So if we want to keep around the baseline metrics for a 10-node\ncluster for a day we're looking at something close to 555 MiB of raw\ndata, or ~50 MiB compressed.\n\nRelease note: None"},"comment":{"url":"https://api.github.com/repos/cockroachdb/cockroach/issues/comments/383564031","html_url":"https://github.com/cockroachdb/cockroach/pull/21833#issuecomment-383564031","issue_url":"https://api.github.com/repos/cockroachdb/cockroach/issues/21833","id":383564031,"user":{"login":"petermattis","id":6201335,"avatar_url":"https://avatars0.githubusercontent.com/u/6201335?v=4","gravatar_id":"","url":"https://api.github.com/users/petermattis","html_url":"https://github.com/petermattis","followers_url":"https://api.github.com/users/petermattis/followers","following_url":"https://api.github.com/users/petermattis/following{/other_user}","gists_url":"https://api.github.com/users/petermattis/gists{/gist_id}","starred_url":"https://api.github.com/users/petermattis/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/petermattis/subscriptions","organizations_url":"https://api.github.com/users/petermattis/orgs","repos_url":"https://api.github.com/users/petermattis/repos","events_url":"https://api.github.com/users/petermattis/events{/privacy}","received_events_url":"https://api.github.com/users/petermattis/received_events","type":"User","site_admin":false},"created_at":"2018-04-23T12:52:13Z","updated_at":"2018-04-23T12:52:13Z","author_association":"CONTRIBUTOR","body":"@mrtracy This is the PR I mentioned last week. I'm not at all tied to the approach done in this PR, though I do have the requirement that we can retrieve all of the raw timeseries data efficiently. I tried using the existing timeseries APIs and retrieving all of the timeseries data was quite slow. Maybe I was just doing something wrong."}}
