Time series generator

This issue is a proposal to generate and simulate time serie from a set of sensors.

Time series generator configuration

Simple configuration to generate time serie with a period of 5 seconds from 2012-04-23T18:25:00.000Z to 2012-04-23T18:25:15.000Z.

masks:
  - selector:
      jsonpath : 'timestamp'
      mask: 
        timeserie:
          period: "5s" # 1s by default
          from: "2012-04-23T18:25:00.000Z"  # current time by default
          to: "2012-04-23T18:25:15.000Z" # empty by default that mean endless time serie generator         

The following command generate timeserie dataset

$ echo '{"timestamp": "" }' |  pimo
{"timestamp": "2012-04-23T18:25:00.000Z" }
{"timestamp": "2012-04-23T18:25:05.000Z" }
{"timestamp": "2012-04-23T18:25:10.000Z" }

Multi-Sensors configuration

Timeserie mask is not streamable. It start to generate data after the close of the input stream. Each input line is a sensor configuration and timeserie mask generate data for each sensors.

$ echo '{ "id": 1, "timestamp": "" }\n'{"id": 2, "timestamp": "" }' |  pimo
{"id": 1, "timestamp": "2012-04-23T18:25:00.000Z" }
{"id": 2, "timestamp": "2012-04-23T18:25:00.000Z" }
{"id": 1, "timestamp": "2012-04-23T18:25:05.000Z" }
{"id": 2, "timestamp": "2012-04-23T18:25:05.000Z" }
{"id": 1, "timestamp": "2012-04-23T18:25:10.000Z" }
{"id": 2, "timestamp": "2012-04-23T18:25:10.000Z" }

Time Serie simulation

If the simulate option is activating timeserie wait for the period between each data generation.

masks:
  - selector:
      jsonpath : 'timestamp'
      mask: 
        timeserie:
          period: "5s" # 1s by default
          from: "2012-04-23T18:25:00.000Z"  # current time by default
          to: "2012-04-23T18:25:15.000Z" # empty by default that mean endless time serie generator    
          simulate: true # false by default
