Enables writing to multiple statsite instances for example. -* BlackholeSink : Sinks to nowhere - -In addition to the sinks, the `InmemSignal` can be used to catch a signal, -and dump a formatted output of recent metrics. For example, when a process gets -a SIGUSR1, it can dump to stderr recent performance metrics for debugging. - -Labels ------- - -Most metrics do have an equivalent ending with `WithLabels`, such methods -allow to push metrics with labels and use some features of underlying Sinks -(ex: translated into Prometheus labels). - -Since some of these labels may increase greatly cardinality of metrics, the -library allow to filter labels using a blacklist/whitelist filtering system -which is global to all metrics. - -* If `Config.AllowedLabels` is not nil, then only labels specified in this value will be sent to underlying Sink, otherwise, all labels are sent by default. -* If `Config.BlockedLabels` is not nil, any label specified in this value will not be sent to underlying Sinks. - -By default, both `Config.AllowedLabels` and `Config.BlockedLabels` are nil, meaning that -no tags are filetered at all, but it allow to a user to globally block some tags with high -cardinality at application level. - -Examples --------- - -Here is an example of using the package: - -```go -func SlowMethod() { - // Profiling the runtime of a method - defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now()) -} - -// Configure a statsite sink as the global metrics sink -sink, _ := metrics.NewStatsiteSink("statsite:8125") -metrics.NewGlobal(metrics.DefaultConfig("service-name"), sink) - -// Emit a Key/Value pair -metrics.EmitKey([]string{"questions", "meaning of life"}, 42) -``` - -Here is an example of setting up a signal handler: - -```go -// Setup the inmem sink and signal handler -inm := metrics.NewInmemSink(10*time.Second, time.Minute) -sig := metrics.DefaultInmemSignal(inm) -metrics.NewGlobal(metrics.DefaultConfig("service-name"), inm) - -// Run some code -inm.SetGauge([]string{"foo"}, 42) -inm.EmitKey([]string{"bar"}, 30) - -inm.IncrCounter([]string{"baz"}, 42) -inm.IncrCounter([]string{"baz"}, 1) -inm.IncrCounter([]string{"baz"}, 80) - -inm.AddSample([]string{"method", "wow"}, 42) -inm.AddSample([]string{"method", "wow"}, 100) -inm.AddSample([]string{"method", "wow"}, 22) - -.... -``` - -When a signal comes in, output like the following will be dumped to stderr: - - [2014-01-28 14:57:33.04 -0800 PST][G] 'foo': 42.000 - [2014-01-28 14:57:33.04 -0800 PST][P] 'bar': 30.000 - [2014-01-28 14:57:33.04 -0800 PST][C] 'baz': Count: 3 Min: 1.000 Mean: 41.000 Max: 80.000 Stddev: 39.509 - [2014-01-28 14:57:33.04 -0800 PST][S] 'method.wow': Count: 3 Min: 22.000 Mean: 54.667 Max: 100.000 Stddev: 40.513 \ No newline at end of file diff --git a/vendor/github.com/armon/go-metrics/const_unix.go b/vendor/github.com/armon/go-metrics/const_unix.go deleted file mode 100644 index 31098dd57e5..00000000000 --- a/vendor/github.com/armon/go-metrics/const_unix.go +++ /dev/null @@ -1,12 +0,0 @@ -// +build !windows - -package metrics - -import ( - "syscall" -) - -const ( - // DefaultSignal is used with DefaultInmemSignal - DefaultSignal = syscall.SIGUSR1 -) diff --git a/vendor/github.com/armon/go-metrics/const_windows.go b/vendor/github.com/armon/go-metrics/const_windows.go deleted file mode 100644 index 38136af3e42..00000000000 --- a/vendor/github.com/armon/go-metrics/const_windows.go +++ /dev/null @@ -1,13 +0,0 @@ -// +build windows - -package metrics - -import ( - "syscall" -) - -const ( - // DefaultSignal is used with DefaultInmemSignal - // Windows has no SIGUSR1, use SIGBREAK - DefaultSignal = syscall.Signal(21) -) diff --git a/vendor/github.com/armon/go-metrics/inmem.go b/vendor/github.com/armon/go-metrics/inmem.go deleted file mode 100644 index 7c427aca979..00000000000 --- a/vendor/github.com/armon/go-metrics/inmem.go +++ /dev/null @@ -1,339 +0,0 @@ -package metrics - -import ( - "bytes" - "fmt" - "math" - "net/url" - "strings" - "sync" - "time" -) - -var spaceReplacer = strings.NewReplacer(" ", "_") - -// InmemSink provides a MetricSink that does in-memory aggregation -// without sending metrics over a network.
