Tobias Schmidt 765c1152ca Rename process_goroutines to go_goroutines
The decision was made to use the language name for language specific
metrics, so go_goroutines is the right names similar to
go_gc_duration_seconds.

The dependency matttproud/golang_protobuf_extensions changed its package
layout and thereby broke the Prometheus client_golang build. This fixes
it.

Julius Volz 738b69e61a Use non-rewritten Godep imports. 2015-02-27 16:49:40 +01:00
Julius Volz 169c8a68e1 Use godep with import rewriting for vendoring.
The new vendoring was produced by running:

    godep save -r ./examples/... ./prometheus/... ./text/... ./model/... ./extraction/...

Two things to note:

- "extraction/processor0_0_{1,2}_test.go" imported a package from
  "github.com/prometheus/prometheus", all for just one tiny testing
  function. To not have to deal with a circular vendoring dependency, I
  simply replaced the usage of the function by some in-line logic.

- godep grouped the rewritten imports slightly differently for some
  reason, but at least the standard library imports are still in a
  separate section. Not sure if it's worth manually keeping our old
  import grouping scheme or if we should simply use that godep-generated
  one.

beorn7 b1e7299877 Turned "le" and "quantile" label names into constants. 2015-02-19 15:54:26 +01:00
beorn7 b37ca982a9 Add support for optionally missing +Inf bucket in protobuf.
Also, clean up style issues in metricfamilyprocessor.go.

Julius Volz 765fdaf37e Update protobuf library package name.
The Golang protocol buffer library has now moved to GitHub:

https://github.com/golang/protobuf

Although "go get"-ing the old package name still works, moving
everything to the new one will make vendoring cleaner.

Brian Brazil 6f2f8f28e8 Add support for histograms to parsers, extraction and creation.
This does not include a histogram metric usable from the go client.

Bjoern Rabenstein 5d40912fd2 Complete rewrite of the exposition library.
This rewrite had may backs and forths. In my git repository, it
consists of 35 commits which I cannot group or merge into reasonable
review buckets. Gerrit breaks fundamental git semantics, so I have to
squash the 35 commits into one for the review.

I'll push this not with refs/for/master, but with refs/for/next so
that we can transition after submission in a controlled fashion.

For the review, I recommend to start with looking at godoc and in
particular the many examples. After that, continue with a line-by-line
detailed review. (The big picture is hopefully as expected after
wrapping up the discussion earlier.)

Bjoern Rabenstein 84dc53148d Enable the Golang client library to create the new text formats.
Most important here is the simple & flat text format, but while I'm on
it, I have also added the text representations for protobufs (which is
purely meant for debugging purposes). I hope my basic idea about
handling those various protocols (and the text package) becomes
clearer now.

Bjoern Rabenstein e5dc0421cd Move signature.go and related tests to the model package.
The LabelsToSignature function is now used outside of the prometheus
package, too. Leaving it in the prometheuos package is misleading
design and will lead to circulat import chains soon.

Bjoern Rabenstein ecac33bed0 Conversion back and forth between MetricFamily protobuf and text format.
The idea here is to always go via the protobufs if dealing with the
text format. That won't always be the most efficient way, but it
avoids the multiplicity of conversion routines required for direct
conversion (e.g. text format -> internal representation in the
Prometheus server). The loss of efficiency is acceptable because the
text format should not be used in high performance (high throughput,
low latency) situations anyway.

In that way, the text format stays perfectly isolated from other parts
of the code. To receive text format, just plug the conversion in
before the code path that normally reads protobufs. Correspondingly,
for sending text format, simply replace the WriteDelimited call by a
text.Create call.

Nevertheless, the conversion code itself is optimized for efficiency
and minimized memory churn (which was one of the reason for handcoding
the parser and not using a lexer/parser code generation tool).
