RRD

This library relies upon rrdtool being installed an available. It can be used to create, destroy, update, fetch, dump, and restore an RRD database. It's a work in progress, and pull-requests are welcomed (with tests, please).

Examples

Creating a database

RRD = require('rrd').RRD
rrd = new RRD('valid.rrd')
rrd.create ["DS:temperature:GAUGE:600:U:U", "RRA:AVERAGE:0.5:1:300"], {}, (err) ->
  if err
    console.log "error: #{err}"

Updating a database

RRD = require('rrd').RRD
rrd = new RRD('valid.rrd')
rrd.update new Date, [100], (err) ->
  if err
    console.log "error: #{err}"

Querying the database

rrdTime = (date) ->
  return Math.round(date.valueOf() / 1000)

RRD = require('rrd').RRD
rrd = new RRD('valid.rrd')
rrd.fetch rrdTime(rrdStartTime), rrdTime(new Date), (err, results) ->
  if err
    console.log "error: #{err}"
  else
    console.log results
