Monitoring with alarms - Amazon IoT SiteWise Monitor
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Monitoring with alarms

Alarms alert you and your team when equipment or processes perform sub-optimally. Optimal performance of a machine or process means that the values for certain metrics should be within a range of high and low limits. When these metrics are outside their operating range, equipment operators must be notified so that they can fix the issue. Alarms help you quickly identify issues and notify operators to maximize performance of your equipment and processes.

Note

The alarm notifications feature isn't available in the China (Beijing) Region.

Amazon IoT SiteWise Monitor supports two types of alarms:

  • Alarms that detect in the Amazon Cloud – You can view and customize the thresholds and notification settings for these alarms. You can also acknowledge and snooze these alarms.

    Important

    After you enable the alarms feature for your portals, members of your organization can create only Amazon IoT Events alarms in your portals.

  • External alarms – These alarms detect on external equipment and then send the alarm state to the Amazon Cloud. You can't customize, acknowledge, or snooze these alarms. These alarms don't have any information other than their state.

Alarms have the following states:

  • Normal – The alarm is enabled but inactive. The equipment or process operates as expected.

  • Active – The alarm is active. The equipment or process is outside its operating range and needs attention.

  • Acknowledged – An operator acknowledged the state of the alarm.

  • Latched – The alarm returned to normal but was active and no operator acknowledged it. The equipment or process requires attention to reset the alarm to normal.

  • Snoozed – The alarm is inactive because an operator snoozed the alarm. The operator defines the duration for which the alarm snoozes. After that duration, the alarm returns to normal state.

  • Disabled – The alarm is inactive and won't detect any changes.

You can perform the following alarm-related tasks.
