-----------------------------
Summary: Improve master metrics/snapshot performace (was: Improve
metrics/snapshot performace)
> Improve master metrics/snapshot performace
> ------------------------------------------

> Key: MESOS-4740
> URL: https://issues.apache.org/jira/browse/MESOS-4740
> Project: Mesos
> Issue Type: Task
> Reporter: Cong Wang
> Assignee: Cong Wang
>
> [~drobinson] noticed retrieving metrics/snapshot statistics could be very
> inefficient.
> {noformat}
> [user@server ~]$ time curl -s localhost:5050/metrics/snapshot
> real 0m35.654s
> user 0m0.019s
> sys 0m0.011s
> {noformat}
> MESOS-1287 introduces a timeout parameter for this query, but for
> metric-collectors like ours they are not aware of such URL-specific
> parameter, so we need:
> 1) We should always have a timeout and set some default value to it
> 2) Investigate why metrics/snapshot could take such a long time to complete
> under load, since we don't use history for these statistics and the values
> are just some atomic read.
