Summary quantiles are not exposed anymore for certain metrics in thanos-query

[bandesz]

Thanos, Prometheus and Golang version used

Thanos version: 0.6.1
Prometheus version: 2.6.1

What happened

prometheus_engine_query_duration_seconds isn't exposed anymore with the {app="thanos-query"} label. (examples/grafana/thanos-query.json refers to this).

Was this metric removed? (I couldn't find anything relevant in the changelogs.)
Can this be a problem of the Prometheus+Thanos version combo we're using?

Edit: The following metrics doesn't have the quantiles reported anymore:

• prometheus_engine_query_duration_seconds
• http_request_size_bytes
• http_response_size_bytes

Hm. I can see it being exposed on our services as summary. Maybe no query was triggered against this Querier that's why?

I can see prometheus_engine_query_duration_seconds_count and prometheus_engine_query_duration_seconds_sum

Indeed, I see those metrics on 0.7.0. Perhaps you need to run at least one query like @bwplotka says.

I still see prometheus_engine_query_duration_seconds_count and prometheus_engine_query_duration_seconds_sum but previously we had the quantiles, e.g.:

prometheus_engine_query_duration_seconds{quantile="0.99",slice="result_sort"}

Where did that go?

[bandesz]

I think this might be caused by #1314 or a similar change.

The following metrics also doesn't have the quantiles reported anymore: http_request_size_bytes and http_response_size_bytes.
