Data Generator

This module generates test data from JSON. The output can be used to test proof of concepts etc.

Settings

Name	Requirements	Purpose	Default
Interval	0 seconds - 24 hours	How often to produce output	1 second
Run on start	true/false	If true output will be produced without delay	true
Number of samples	1 - 100.000	How many unique items to use	10
Add timestamp	true/false	If true a property `timestamp` with the current time is added to each item	false
Output strategy	Random, Ordered, Array	Format and selection of output	Random
JSON	Valid JSON string	The template to produce test-data from	Tip: click on the label to generate a sample

The module will automatically use properties named id as a key if they are of type Integer or Guid.

Examples

Creates 3 objects to be used samples data. The output will be in the same order all the time (1,2,3...1,2,3). The name property will be an identifier to get unique names for each object. data.temp (integer) and data.rpm (double) will be random values.

# Settings:
Interval = 1 second
Number of samples = 3
Output strategy = Ordered
JSON = {
    "id":1,
    "name": "machine",
    "data" : {
        "temp": 67.5,
        "rpm": 4600
    }
}

Set 'name' to be an identifier
Set 'data.temp' to be random between 55.5-80.5
Set 'data.rpm' to be random between 3000-6000
