> Taskmanager metrics not accessible via REST
> -------------------------------------------
>
> Key: FLINK-5419
> URL: https://issues.apache.org/jira/browse/FLINK-5419
> Project: Flink
> Issue Type: Bug
> Components: Metrics, Webfrontend
> Affects Versions: 1.2.0, 1.3.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Fix For: 1.2.0, 1.3.0
>
>
> There is currently a URL clash between the TaskManagersHandler and
> TaskManagerMetricsHandler, with both being routed to
> {code}
> /taskmanagers/:taskmanagerid/metrics
> {code}
> As a result it is not possible to query the full set of metrics for a
> taskmanager, but only the hard-coded subset that is displayed on the metrics
> tab on the taskmanager page.
> This is a side-effect of 6d53bbc4b92e651786ecc8c2c6dfeb8e450a16a3 making the
> URL's more consistent. The TaskManager page in the web-interface has 3 tabs:
> Metrics, Log and Stdout.
> The URLs for these tabs are
> {code}
> /taskmanager/<tmid>/metrics
> /taskmanager/<tmid>/log
> /taskmanager/<tmid>/stdout
> {code}
> which correspond to the REST URL's used. Previously, the metrics tab used
> {code}/taskmanager/<tmid>{code}
> However, 70704de0c82cbb7b143dd696221e11999feb3600 then exposed the metrics
> gathered by the metrics system through the REST API. The assumption was that
> general information for the taskmanagers are retrieved via
> /taskmanager/<tmid>, similar to how the job-related URL's are structured,
> which sadly isn't the case.
