Note
You can configure these values for AWS IoT Events alarms, but not external alarms.
Responding to alarms
Note
You can respond to AWS IoT Events alarms, but not external alarms.
Note
You must enable the acknowledge flow on the alarm so that you can acknowledge the alarm. This option is enabled by default if you define the alarm from the AWS IoT SiteWise console.
Ingesting external alarm state
Note
If your data source can't report data in this format, or you can't convert your data to this format before you ingest it, you might choose not to use an alarm property. Instead, you can ingest the data as a measurement property with the string data type, for example. For more information, see Defining data streams from equipment (measurements) and Ingesting data to AWS IoT SiteWise.
