numbat-process

Monitor your process with numbat

var numproc = require('numbat-process')

numproc({
    uri: 'tcp://localhost:8000',
    app: 'myapplication',
})

now every 10 seconds your application will emit these metrics!

'myapplication.memory.rss'
'myapplication.memory.heapTotal'
'myapplication.memory.heapUsed'
'myapplication.js.eventloop'
'myapplication.js.handles'
'myapplication.js.requests'
'myapplication.fds.count'
'myapplication.cpu.percent'

API

• var stop = module.exports(options,interval)
  • options, emitter object or config object for numbat-emitter
  • interval, number ms to poll and report stats. default 10000
  • RETURN: stop function. call it to stop emitting metrics.

disk stats!

if you pass true in options.disk numbat process will also emit local disk metrics.

'disk.use./'
'disk.available./'
'disk.inode-use./'
'disk.inode-available./'

the format is disk.[type].[mount point]

by default numbat-process emits one metric for every disk with a filesystem column starting with /dev.

/dev/sda1 for example

you can also pass an array of mount points you would like to track instead. if you only want disk metrics for / set options.disk = ['/'] and df output will be filtered to only emit metrics for /
