David Kaltschmidt 0a3faee526 Pushed query timings into timings field, added tests 2017-11-17 22:30:59 +01:00
David Kaltschmidt 87c46ea6c3 Renamed TotalEvalTime to EvalTotalTime
* TotalFoo suggested a comprehensive timing, but TotalEvalTime was part
of the Exec timings, together with Queue timings
* The other option was to rename ExecTotalTime to TotalExecTime, but
 there was already ExecQueueTime, suggesting Exec to be some sort of
group

David Kaltschmidt c93e54d240 Adds execution timer stats to the range query
API consumers should be able to get insight into the query run times.
The UI currently measures total roundtrip times. This PR allows for more
fine grained metrics to be exposed.

* adds new timer for total execution time (queue + eval)

* expose new timer, queue timer, and eval timer in stats field of the
 range query response:
```json
{
  "status": "success",
  "data": {
    "resultType": "matrix",
    "result": [],
    "stats": {
      "execQueueTimeNs": 4683,
      "execTotalTimeNs": 2086587,
      "totalEvalTimeNs": 2077851
    }
  }
}
```

* stats field is optional, only set when query parameter `stats` is not
empty

Try it via
```sh
curl 'http://localhost:9090/api/v1/query_range?query=up&start=1486480279&end=1486483879&step=14000&stats=true'
```

Review feedback

* moved query stats json generation to query_stats.go
* use seconds for all query timers
* expose all timers available
* Changed ExecTotalTime string representation from Exec queue total time to Exec total time

Alberto Cortés 2c9739162e utils/stats: remove dead code 2017-09-26 16:32:45 +02:00
Julius Volz 3bfec97d46 Make the storage interface higher-level.
See discussion in
https://groups.google.com/forum/#!topic/prometheus-developers/bkuGbVlvQ9g

The main idea is that the user of a storage shouldn't have to deal with
fingerprints anymore, and should not need to do an individual preload
call for each metric. The storage interface needs to be made more
high-level to not expose these details.

This also makes it easier to reuse the same storage interface for remote
storages later, as fewer roundtrips are required and the fingerprint
concept doesn't work well across the network.

NOTE: this deliberately gets rid of a small optimization in the old
query Analyzer, where we dedupe instants and ranges for the same series.
This should have a minor impact, as most queries do not have multiple
selectors loading the same series (and at the same offset).

beorn7 c740789ce3 Improve predict_linear
Fixes https://github.com/prometheus/prometheus/issues/1401

This remove the last (and in fact bogus) use of BoundaryValues.

Thus, a whole lot of unused (and arguably sub-optimal / ugly) code can
be removed here, too.
