Neil Conway commented on MESOS-6228:
------------------------------------
If we added a request timeout, the HTTP request would return successfully if
fetching any metric times out. Not clear that this is actually better behavior.
In this situation, we would {{VLOG(1)}} which metric has timed out; we could
perhaps increase the verbosity of that error message and then enable the
request timeout.
> Add timeout to /metrics/snapshot calls in tests

> Components: tests

> Labels: mesosphere, newbie++
>
> In the unit tests, {{Metrics()}} does an {{http::get}} of the
> {{/metrics/snapshot}} endpoint. No {{timeout}} parameter is provided. That
> means if any metric cannot be fetched, the request hangs for 15 seconds and
> then dies with a mysterious / unclear error message. Digging into which
> metric has hung and for what reason requires a lot of time / debugging.
