Alert Manager helps you define your own thresholds for data values and then perform specific actions for each defined threshold. For example, if you’re plotting a real-time temperature chart and you wish to play a sound when the temperature reaches between say 90 and 100 Fahrenheit, you can easily do so using Alert Manager.

Alert Manager allows you to define any number of alert threshold ranges for the chart. The threshold range just shouldn't overlap. For each threshold range, you can specify one of the following actions:

  • Call a JavaScript function and pass parameters to it
  • Show a pre-defined annotation on the chart
  • Play a MP3 sound, which is dynamically loaded.

The angular gauge supports alert manager. You may please see the Alert Manager section on how to implement alert manager in this chart.
