Go-metrics Exporters

Export go-metrics to multiple upstreams with Emitter, and gracefully close it.

Features

• Gracefully report last metrics when shutting down
• Report to multiple upstreams simultaneously
• Builtin influx v1 and v2 support
• Implement Emitter to support in-house upstreams

Usage Examples

Report to stdout:

reg := metrics.NewRegistry()
stdout := emitters.NewStdoutEmitter()
rep, err := exporters.NewReporter(reg, 1*time.Second).WithEmitter(stdout).Start()

// Should close it when shutting down application
rep.Close()

Report to stdout and influx v2:

inf, _ := influx.NewV2Emitter(influxUrl, "bucket")
rep, err := exporters.NewReporter(reg, 1*time.Second).
	WithEmitter(stdout).
	WithEmitter(inf).
	Start()
// Should close it when shutting down application
rep.Close()
