    DEPRECATED: cubed

    This module has been deprecated as of November 9, 2015. It will be removed from npm on November 1, 2016.

    A udp-based, cube backend for statsd


    from your statsd directory

    npm install cubed

    Add the cubed backend configuration to your statsd configuration file.

        cubeHost: 'localhost',
        cubePort: 1180,
        backends: ['./node_modules/cubed/index.js'],
        deleteIdleStats: true

    pro tip: although not required, you probably want to set deleteIdleStats to true in the cubed configuration block. cube's evaluator automatically populates sparse data with 0 values. thus, there is no need to send null stats to the collector.


    • cubeHost: localhost
    • cubePort: 1180


    once the cubed backend is installed and statsd is restarted, data will automatically be sent to cube at each statsd flush. the cube event data object is generated based on the type of statsd event received.

    for example, the statsd event:


    would generate (at flush time) the following cube event:

      "type": "keiju",
      "time": "2013-07-12T17:10:00Z",
      "data": {
        "c": 3

    cube, in turn, would generate a new document in the keiju_events collection:

      "_id": ObjectId("..."),
      "t": ISODate("2013-07-12T17:10:0Z"),
      "d": {
        "c": 3

    cube's data keys are based on the default type keys in statsd events:

    • c for counters
    • ms for timers
    • g for guages
    • s for sets

    cube automatically manages the related keiju_metrics colleciton. the following evaluator request would sum the received counts at 1 minute intervals (remember: cube's evaluator uses fixed resolution times).


    which would respond with:

            "time": "2013-07-12T17:10:00Z",
            "value": 3

    pro tip: do not use cube's evaluator at time resolutions smaller than your statsd flush interval (the resulting data will include inaccurate 0 values which do not reflect observed behavior). we have found that it is helpful to include the available time resolutions within internal metrics analysis docs.


    • statsd internal statistics (e.g. counters.statsd.packets_received) are not sent to cube.
    • raw timer data is not provided to cube; cube only receives the summary timer statistics (mean, upper count, sum, etc).
    • statsd is designed to collect data in (nearly) real time. as a result, there is currently no good way to pass a timestamp for a previously recorded event to cube from statsd. all events are timestamped by cube's collector when they are received by cube.

    namespacing statsd → cube

    in statsd, periods are used to namespace events. unfortunately, cube does not (yet) support periods in event names though they are valid collection names. (hopefully this is patched soon...)

    for now, all periods (and spaces) are converted to underscores. then, all non-alphanumeric or non-underscore characters are removed.


    work in progress. use with caution.

    npm test

    no tcp?

    cubed uses udp to communicate with the cube instance. although tcp is supported by cube, it is not supported by statsd. statsd is designed to be "fire and forget". so too is cubed. if you are looking for guaranteed data persistence, consider using cube's tcp interface directly rather than through statsd and cubed.
