Björn Rabenstein 86bd077f30 Merge pull request #113 from oliver006/add_gc_metrics 
Add garbage collection stats

beorn7 0e0e6bff80 Rework the signature aka fingerprint functions. 
Move everything over to a more expensive but less collision-prone way.
However, keep the old fingerprinting under the name "FastFingerprint"
to be used in the storage layer (where we need collision detection
anyway).

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. 
Move all Pushgateway related top-level functions to push.go.
 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.)
