api: creates versioned package for prometheus v1 api
This commit creates a new package to hold the prometheus
v1 API interface. This interface will contain all the funcionality
exposed by Prometheus v1 HTTP API.

The underlying http client is kept on the api package since it
may be reused across diferent API versions and also by the Alertmanager
api package (to come.)

Tobias Schmidt ae77d82d88 Fix invalid Timer (gauge) example
The example method is assumed to be used as main() function. As a main()
function doesn't have any return values, the example doesn't compile and
is invalid.

beorn7 9c4b7780d7 Allow Summaries with empty objectives and deprecate DefObjectives
This also updates all tests and examples to use explicitly set
objectives.

In v0.10, DefObjectives will be completely removed, and the default
Summary will have no objectives then.

beorn7 6bff9dc5a4 Make heap_released_bytes a Gauge.
It's not a counter after all.

Also, remove a misleading part of the sys_bytes help string.

beorn7 89ca0458cb Change the Timer API
This finally makes the (presumably) common simple case as simple as it
gets.

The still quite common (but less common) case of using a Gauge is
slightly more verbose now, but not needing to provide a separate
constructor is totally worth it.

Finally, the advanced use case is not really more verbose as in my
original suggestion. However, the logic to decide which Observer to
use is now all in the ObserverFunc handed in at construction
time. This is deliberate and desired. It makes sure the selection
mechanism is all spelled out there. No surprises buried deep in the
function code somewhere.

Bring Gauges and Counters in line with client library guidelines
2016-11-18 19:33:10 +01:00
beorn7 606b8f85e5 - Point from Inc and Dec to Add and Sub in doc comments.
- Deprecate Untyped for direct instrumentation.

- Add a SetToCurrentTime method to Gauge

Note that adding the SetToCurrentTime method is not really following
Go's principle of lean interfaces. However, the Gauge interface is
already quite fat. (The only methods really required are Set and
Add. Everything else could be expressed in terms of those two.) So we
have already quite a few "convenience" methods traditionally, so I
think we should stay consistent here.

The alternatives would be:

- Not support SetToCurrentTime at all (it's only a SHOULD in the
  guidelines).

- A top level function `SetToCurrentTime(Gauge)`.

- Just a helper `CurrentTime()` that returns the curent unix time in
  seconds as a float (which is pretty verbose using the standard
  library, see code in this commit). This would allow
  `myGauge.Set(CurrentTime)`.

Weighing all circumstances, I believe the way in this commit is the
least evil. Issue #223 could be used to rework interfaces more
fundamentally in a breaking change if feasible.
