About

edVent is a visualization tool that helps debugging event based software, and more specifically state machines. It is based on enyojs and d3js. Load a dump of yours events formatted as a json array and you can easily see what happened.

Json input format

The input logs are structured in json objects. The log structure is the following one:

{
  "t": "iso8601 date",
  "class":"string",
  "method":"string",
  "obj":"string",
  "type":"string",
  "data_in":{object}
  "data_out":{object}
}

• t : The timestamp of the event
• class : The class name
• method : The method name
• obj : the object identifier
• type : event|entry|exit|link
• data_in : Contains the list of input parameters
• data_out : Contains the list of output parameters (result).

Example:

[
    { "t" : "0", "class" : "hsm1", "obj" : "1", "method" : "state3", "data_in" : {} },
    { "t" : "0", "class" : "hsm1", "obj" : "1", "method" : "state2", "data_in" : {} },
    { "t" : "0", "class" : "hsm1", "obj" : "2", "method" : "state3", "data_in" : {} },
]
