Peter Bourgon a6f3300b8d s/ext/pbutil/g
The dependency matttproud/golang_protobuf_extensions changed its package
layout and thereby broke the Prometheus client_golang build. This fixes
it.

Julius Volz 2b9d181f5b Merge process_collector{,procfs}.go files into one. 2015-03-31 18:24:46 +02:00
Julius Volz 21b7c6b048 Always build the procfs collector.
The cgo dependency in the "procfs" package is being removed in:

  https://github.com/prometheus/procfs/pull/4

So now it should be fine to always import the "procfs" package and have
it determine dynamically at runtime whether the proc filesystem is
actually there.

This fixes a problem for users which were vendoring client_golang on
MacOS X, but building the result on Linux (the procfs package was
missing in the vendored packages).

beorn7 f3cda15667 Add functions to push individual collectors to a Pushgateway.

2015-03-15 19:29:57 +01:00
beorn7 a762e0612e Allow the metric family injection hook to merge with existing metric families.
If a metric family returned by the injection hook already exists (with
the same name), then its metrics are simply merged into that metric
family. With enabled collect-time checks, even uniqueness is checked,
but in general, things stay the same that the caller is responsible to
ensure metric consistency.

This fixes https://github.com/prometheus/pushgateway/issues/27 .

Björn Rabenstein e5098ac1ff Merge pull request #91 from prometheus/beorn7/license-cleanup
Add licenses of vendored code left out by godep.
2015-03-04 17:00:14 +01:00
beorn7 4aa58b9029 Add licenses of vendored code left out by godep.
As it looks, `godep update ...` will preserve the files.

Obviously, if you blow away everything and run a `godep save ...` from
scratch, those files will be missing again. A `godep save` to add new
dependencies without blowing away the `Godeps` directory should work
fine, though.

beorn7 cbe221c969 Switch to sync.Pool.
sync.Pool is after all faster than the home-made free list. Especially
under contention. To prove that, this commit also adds a benchmark for
concurrent fingerprint calculation.

Benchmark results:
(Run with -cpu=1,2,4. x-y -> x goroutines with GOMAXPROCS=y.)

Unify fingerprinting aka signature calculation.
2015-03-03 18:03:08 +01:00
beorn7 af21d456db Unify fingerprinting aka signature calculation.
This fixes https://github.com/prometheus/client_golang/issues/74 .

IT CHANGES THE FINGERPRINTING AND THEREFORE INVALIDATES EACH AND EVERY
PERSISTED FINGERPRINT (I.E. YOU HAVE TO WIPE THE STORAGE TO USE THIS).

This commit removes the LabelValuesToSignature function as it is used
nowhere (and broken in the way it is implemented right now).

Also, remove one more golint warning.
