numbat-powered metrics collector & redirector


Numbat-powered metrics system: monitoring, alerting, and historical analysis. The collector sits in front of Numbat-Analyzer and InfluxDB in the same way that statsd sits in front of Graphite. This system, however, does absolutely no aggregation or manipulation of the data at all (yet). It merely multiplexes & buffers when necessary.

See numbat-analyzer for more information on the system.

The collector is a service. You are intended to run it anywhere you like, perhaps many instances of it. You could run one on every hosts where you run services and communicate with it using a socket. Or you could run a few collectors and communicate using TCP or UDP.

Definitely pre 1.0; many error cases unhandled as yet.

> npm install -g numbat-collector
> numbatd configuration.js

The configuration file looks like this:

module.exports =
        name: 'numbat-1',
        console: true,
        path: '/var/log/numbatd'
    listen: { host: 'localhost', port: 3333 },
        { type: 'log', name: 'numbat-1', path: './numbat.log' },
        { type: 'analyzer',  host: 'localhost', port: 5555 },
            type: 'influxdb',
                { host: '',  port: 8086 },
                { host: '',  port: 8086 },
            username: 'numbat',
            password: 'my-top-secret',
            database: 'numbat'

The configuration options are described in more detail below.

  • console: true: output to the console
  • NODE_ENV=dev set in environment: log to console, pretty-printed (no need to pipe to bistre)
  • path: '/path/to/directory': log to a file in the given directory. The file will be named name.log, where 'name' is whatever you specified in that field.
  • listen: { host: '', port: 3333 } -- listen for incoming data over tcp on the given port
  • listen: { host: 'localhost', port: 3333, udp: true } -- listen for udp data
  • listen: { path: '/path/to/foo.sock' } -- connect to the given unix domain socket
  • InfluxDB: a time-series database that can drive interesting dashboards.
  • numbat-analyzer: the alerting & monitoring component of the numbat-powered metrics system.
  • a json-formatted logfile (using bole); in case you want logging for any reason

Sure! Write tests with Lab & must. Use BSD/Allman bracing or I will stare at you funny and not take your pull request.
