    concurix-waterfalltransform

    Build Status

    Transform functions that take raw Concurix waterfall trace formats and transform them into other useful data structures.

    Install

    npm install --save concurix-waterfalltransform`

    Usage

    var xform = require('concurix-waterfalltransform')

    API

    xform.graph(waterfall)

    Convert a raw waterfall trace into a 'nodes, links' structure with the following schema:

    {
      "nodes": [{
        "id": "some id",
        "duration": "in microseconds",
        "child_duration": "in microseconds",
        "exclusive_duration": "duration - child_duration"
        "num_calls": "number of calls"
      }],
      "links": [{
        "id": "source~target",
        "source": "id",
        "target": "id",
        "num_calls": "number of calls",
        "total_delay": "in microseconds"
      }]
    }

    xform.enhanceWaterfall(waterfall, options)

    Options is an object with the following fields:

    {
        summaryFactor: 1000  // this controls the summarization factor.  Andything smaller than 1/summaryFactor in size will be aggregated
    }

    Performs an inplace enhancement of the waterfall trace data structure. The following fields will be added:

    {
      "waterfalls": [
        "maxEnd":           //the maximum 'end' value in this waterfall
        "summary": {        //a summary view of the waterfall
          "subSegments": [
            {
     
            }
          ]
        },
        "fnSegs": []       //array referencing just the function segments
        "waitSegs": []     //array referencing just the wait segments
        "segments": [
          {
            "id":          //a synthetic id for the segment
            ...
            "subSegments": [
              {
                "id":      //a synthethic id for the subsegment
                "start": 0
                "end": 0
                "exclusive": 0
                "parent":   //points back to the parent segment
              }
            ]
          }
        ]
      ]
    }
