process-reporter v2.5.0

process-reporter

Reports information about your node process to statsd. Use it like this:

var ProcessReporter = require('process-reporter');

var processReporter = ProcessReporter({
    statsd: statsdClient
});

processReporter.bootstrap();

It currently reports these stats:

• yourapp.process-reporter.handles number of libuv handles
• yourapp.process-reporter.requests number of libuv requests
• yourapp.process-reporter.memory-usage.rss resident set size of procss
• yourapp.process-reporter.memory-usage.heap-total total size of v8 heap
• yourapp.process-reporter.memory-usage.heap-used amt of v8 heap used
• yourapp.process-reporter.lag-sampler event loop lag
• yourapp.process-reporter.gc.{gc-type}.pause-ms length of GC pauses
• yourapp.process-reporter.gc.{gc-type}.heap-used +/- amount of bytes GCd
• yourapp.process-reporter.gc.{gc-type}.heap-total +/- changes in heap total

To destroy the reporter just call processReporter.destroy();

Docs

The ProcessReporter constructor takes an options dictionary:

• options.statsd, a per-worker statsd to write per-worker stats to
• options.clusterStatsd, a cluster-wide statsd to write cluster-wide stats to

You can pass in an optional clusterStatsd that will be used to emit lag-sampler and gc.{gc-type}.pause-ms stats that are cluster wide so that your statsd aggregation can calculate more accurate P99s
