Update client-go to v10.0.0 (Kubernetes 1.13) (#2382)
* Update client-go to v10.0.0 (Kubernetes 1.13) This fix updates client-go to v10.0.0 which matches Kubernetes 1.13 (released several days ago). Other changes in Gopkg.yaml: - Updated apimachinary, api, klog, yaml associated with k8s version go dep will not automatically match the version. - Added [prune] field (otherwise go dep will not prune automatically) Signed-off-by: Yong Tang <yong.tang.github@outlook.com> * Updated Gopkg.lock Signed-off-by: Yong Tang <yong.tang.github@outlook.com> * Updated vendor for client-go v10.0.0 Signed-off-by: Yong Tang <yong.tang.github@outlook.com>

go-metrics
|
||||
==========
|
||||
|
||||
|
||||
|
||||
Go port of Coda Hale's Metrics library: <https://github.com/dropwizard/metrics>.
|
||||
|
||||
Documentation: <http://godoc.org/github.com/rcrowley/go-metrics>.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Create and update metrics:
|
||||
|
||||
```go
|
||||
c := metrics.NewCounter()
|
||||
metrics.Register("foo", c)
|
||||
c.Inc(47)
|
||||
|
||||
g := metrics.NewGauge()
|
||||
metrics.Register("bar", g)
|
||||
g.Update(47)
|
||||
|
||||
r := NewRegistry()
|
||||
g := metrics.NewRegisteredFunctionalGauge("cache-evictions", r, func() int64 { return cache.getEvictionsCount() })
|
||||
|
||||
s := metrics.NewExpDecaySample(1028, 0.015) // or metrics.NewUniformSample(1028)
|
||||
h := metrics.NewHistogram(s)
|
||||
metrics.Register("baz", h)
|
||||
h.Update(47)
|
||||
|
||||
m := metrics.NewMeter()
|
||||
metrics.Register("quux", m)
|
||||
m.Mark(47)
|
||||
|
||||
t := metrics.NewTimer()
|
||||
metrics.Register("bang", t)
|
||||
t.Time(func() {})
|
||||
t.Update(47)
|
||||
```
|
||||
|
||||
Register() is not threadsafe. For threadsafe metric registration use
|
||||
GetOrRegister:
|
||||
|
||||
```go
|
||||
t := metrics.GetOrRegisterTimer("account.create.latency", nil)
|
||||
t.Time(func() {})
|
||||
t.Update(47)
|
||||
```
|
||||
|
||||
**NOTE:** Be sure to unregister short-lived meters and timers otherwise they will
|
||||
leak memory:
|
||||
|
||||
```go
|
||||
// Will call Stop() on the Meter to allow for garbage collection
|
||||
metrics.Unregister("quux")
|
||||
// Or similarly for a Timer that embeds a Meter
|
||||
metrics.Unregister("bang")
|
||||
```
|
||||
|
||||
Periodically log every metric in human-readable form to standard error:
|
||||
|
||||
```go
|
||||
go metrics.Log(metrics.DefaultRegistry, 5 * time.Second, log.New(os.Stderr, "metrics: ", log.Lmicroseconds))
|
||||
```
|
||||
|
||||
Periodically log every metric in slightly-more-parseable form to syslog:
|
||||
|
||||
```go
|
||||
w, _ := syslog.Dial("unixgram", "/dev/log", syslog.LOG_INFO, "metrics")
|
||||
go metrics.Syslog(metrics.DefaultRegistry, 60e9, w)
|
||||
```
|
||||
|
||||
Periodically emit every metric to Graphite using the [Graphite client](https://github.com/cyberdelia/go-metrics-graphite):
|
||||
|
||||
```go
|
||||
|
||||
import "github.com/cyberdelia/go-metrics-graphite"
|
||||
|
||||
addr, _ := net.ResolveTCPAddr("tcp", "127.0.0.1:2003")
|
||||
go graphite.Graphite(metrics.DefaultRegistry, 10e9, "metrics", addr)
|
||||
```
|
||||
|
||||
Periodically emit every metric into InfluxDB:
|
||||
|
||||
**NOTE:** this has been pulled out of the library due to constant fluctuations
|
||||
in the InfluxDB API. In fact, all client libraries are on their way out. see
|
||||
issues [#121](https://github.com/rcrowley/go-metrics/issues/121) and
|
||||
[#124](https://github.com/rcrowley/go-metrics/issues/124) for progress and details.
|
||||
|
||||
```go
|
||||
import "github.com/vrischmann/go-metrics-influxdb"
|
||||
|
||||
go influxdb.InfluxDB(metrics.DefaultRegistry,
|
||||
10e9,
|
||||
"127.0.0.1:8086",
|
||||
"database-name",
|
||||
"username",
|
||||
"password"
|
||||
)
|
||||
```
|
||||
|
||||
Periodically upload every metric to Librato using the [Librato client](https://github.com/mihasya/go-metrics-librato):
|
||||
|
||||
**Note**: the client included with this repository under the `librato` package
|
||||
has been deprecated and moved to the repository linked above.
|
||||
|
||||
```go
|
||||
import "github.com/mihasya/go-metrics-librato"
|
||||
|
||||
go librato.Librato(metrics.DefaultRegistry,
|
||||
10e9, // interval
|
||||
"example@example.com", // account owner email address
|
||||
"token", // Librato API token
|
||||
"hostname", // source
|
||||
[]float64{0.95}, // percentiles to send
|
||||
time.Millisecond, // time unit
|
||||
)
|
||||
```
|
||||
|
||||
Periodically emit every metric to StatHat:
|
||||
|
||||
```go
|
||||
import "github.com/rcrowley/go-metrics/stathat"
|
||||
|
||||
go stathat.Stathat(metrics.DefaultRegistry, 10e9, "example@example.com")
|
||||
```
|
||||
|
||||
Maintain all metrics along with expvars at `/debug/metrics`:
|
||||
|
||||
This uses the same mechanism as [the official expvar](http://golang.org/pkg/expvar/)
|
||||
but exposed under `/debug/metrics`, which shows a json representation of all your usual expvars
|
||||
as well as all your go-metrics.
|
||||
|
||||
|
||||
```go
|
||||
import "github.com/rcrowley/go-metrics/exp"
|
||||
|
||||
exp.Exp(metrics.DefaultRegistry)
|
||||
```
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
```sh
|
||||
go get github.com/rcrowley/go-metrics
|
||||
```
|
||||
|
||||
StatHat support additionally requires their Go client:
|
||||
|
||||
```sh
|
||||
go get github.com/stathat/go
|
||||
```
|
||||

||||
