Support Protocol Buffer Message Decoding
2013-06-27 02:16:27 -07:00
Matt T. Proud 35125cdac0 Implement Protocol Buffer Stream Decoding
This commit introduces protocol buffer telemetric stream decoding.

Matt T. Proud 03369306e0 Provide Discriminator For Protocol Buf. Streams
This commit introduces an incomplete processor that decodes varint
record length-delimited streams of io.prometheus.client.MetricFamily
Protocol Buffer messages.  The Go client presently does not support
generation of said messages, but this will unblock a number of Java
changes.

Matt T. Proud 10dae5d108 Include relevant server model artifacts.
This commit introduces all relevant server-side artifacts such that the
Result streams can be used by external parties for one-off tools and
such.  This will ultimately better enable us to support additional
wireformats with much more ease.

Matt T. Proud d36afbbd8d Merge pull request #18 from prometheus/refactor/decoder-inclusion
Extract core Prometheus value decoders.
2013-06-10 10:36:40 -07:00
Matt T. Proud 85899b3f4a Extract core Prometheus value decoders.
Bernerd had suggested extracting the value decoders and bundling them
into the client library.  After some reflection, I tend to agree with
this, since we can start breaking the onion of Prometheus itself and
localize the protocol management into its own scope.

A couple of major changes since moving:

- Protocol 0.0.2 has moved to a struct{} so that our tests can perform
  value matching, which cannot be done against function literals.

- Processing now acquires options to dictate behavioral changes of
  metrics bodies.

- Processing no longer closes the stream, thusly returning this to the
  hands of the caller.

- Process() has been renamed to ProcessSingle to better convey that it
  works on complete message bodies.  This paves the way for better
  streaming payload support that the next API version will offer.

Bernerd Schaefer d4ff2cc87a Fix race conditions in metric methods
Methods which expect to use a mutex must be defined for the pointer
value, because mutexes are not copyable.

* The schema and version of telemetry data is exposed through the
  Content-Type header instead of through a custom HTTP Header.

Refactor/reduce marshaling complexity
2013-04-19 06:12:13 -07:00
Bernerd Schaefer 71dd60e431 Registry and Metrics implement json.Marshaler
* Drop `AsMarshallable()` from the Metric interface. Use
  `json.Marshaler` and `MarshalJSON()`, and leverage JSON struct tags
  where possible.

* Add `MarshalJSON()` to Registry and remove `dumpToWriter`, which
  makes the registry handler much simpler.

In addition to simplifying some of the marshalling behavior, this also
has the nice side effect of cutting down the number of
`map[string]interface{}` instances.

- Comments are migrated from ``/* */`` to ``//`` per convention.

- ``NewDefaultHistogram`` helper.

- ``Registry.Handler`` and ``Registry.YieldExporter`` deprecation.

- Cleanup of legacy import paths.

- Updating examples to use acknowledged patterns.

- Parameterizing the random parameter namespaces for ``examples/random/main.go``, which is useful for demoing population behaviors.

Update client to reflect new API needs.

Matt T. Proud 0f93b588cd Update client to reflect new API needs.
1. The output format is now versioned per the Semantic Versioning scheme.  Mainline Prometheus will be adapted to use differing consumption methodologies as the generators' formats evolve to support legacy clients.

2. The telemetry outputter now supports GZIP output encoding.  In sample runs, this cuts the output size in half.

3. Basic sanity tests are added for registration with varying levels of pedanticness.

4. We have support for base labels in the registration and emission phases.

5. We have label support for individual metric mutation operations.

6. A number of simplications have been made.

Having to use Bazaar to access gocheck is onerous.  We have simply
forked it at a revision until all tests can be replaced with
table-driven ones.
