Björn Rabenstein 811a3a9dbf Merge pull request #99 from prometheus/beorn7/push-collector 
Add functions to push individual collectors to a Pushgateway.
 2015-03-15 23:16:01 +01:00
beorn7 f3cda15667 Add functions to push individual collectors to a Pushgateway. 
Move all Pushgateway related top-level functions to push.go.

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.)

Björn Rabenstein cbe3ef2442 Merge pull request #87 from prometheus/beorn7/fingerprint 
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.

Julius Volz ea69be23d0 Add newly vendored libraries to NOTICE file. 2015-02-26 14:04:24 +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.

Use binary search to pick bucket.

beorn7 79efd06178 Use binary search to pick bucket. 
With the usual number of buckets, this doesn't really make a
difference, but it should scale... See the added TODO for the precise
numbers.

juliusv 4627d59e8a Merge pull request #77 from prometheus/update-protobuf-pkg 
Update protobuf library package name.
 2015-02-14 00:04:33 +01:00
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.
