How to Use

Import Wavefront metrics reporter

metrics = require('wavefrontmetrics');

Setting up a Wavefront Reporter

A wavefront reporting interface exists for reporting metrics on a recurring interval. Reporters can be found in reporting/.

// Report to wavefront proxy server every 1000ms.
var report = new metrics.Report();
report.addMetric('com.co.thingA', counter);
//Wavefront proxy listens on port 2878 by default
var reporter = new WavefrontReporter(report, "host1", config.address, config.port,{ tag0: "default" }); //key-value pair object to be passed as Global tags
reporter.start(1000);

Reporting different metric types Examples can be found in unit/.

Adding a counter

//adding a counter
var counter = new Counter({ 'tag1-counter': "countertag_helper" });
counter.inc(5);
report.addMetric("basicCount", counter);
//example output - basicCount.count 5 1489188569.547 tag1-counter=countertag_helper tag0=default

Adding a meter

//adding a meter
var meter = new Meter({ 'tag1-meter': "metertag_helper" });
meter.mark(10);
report.addMetric("myapp.Meter", meter);
//example output - host1.myapp.Meter.count  10 1489188568.542 tag1-meter=metertag_helper tag0=default
