Fleet indexing
You can use fleet indexing to index, search, and aggregate your devices' data from the following sources: AWS IoT registry, AWS IoT Device Shadow, AWS IoT connectivity, AWS IoT Device Management Software Package Catalog, and AWS IoT Device Defender violations. You can query a group of devices, and aggregate statistics on device records that are based on different combinations of device attributes, including state, connectivity, and device violations. With fleet indexing, you can organize, investigate, and troubleshoot your fleet of devices.
Fleet indexing provides the following capabilities.
Managing index updates
You can set up a fleet index to index updates for your thing groups, thing registries,
device shadows, device connectivity, and device violations. When you activate fleet indexing,
AWS IoT creates an index for your things or thing groups. AWS_Things is the index
created for all of your things. AWS_ThingGroups is the index that contains all of
your thing groups. After fleet indexing is active, you can run queries on your index. For
example, you can find all devices that are handheld and have more than 70 percent battery
life. AWS IoT updates the index continually with your latest data. For more information, see
Managing fleet indexing.
Searching across data sources
You can create a query string based on a query language and use it to search across data sources. You can configure data sources in the fleet indexing setting. The query string describes the things that you want to find. You can create queries by using AWS managed fields, custom fields, and any attributes from your indexed data sources. For more information about data sources that support fleet indexing, see Managing thing indexing.
Querying for aggregate data
You can search your devices for aggregate data and return statistics, percentile, cardinality, or a list of things with search queries about particular fields. You can run aggregations on AWS managed fields or any attributes you configure as custom fields within fleet indexing settings. For more information about aggregation query, see Querying for aggregate data.
Monitoring aggregate data and creating alarms by using fleet metrics
You can use fleet metrics to send aggregate data to CloudWatch automatically, analyze trends, and create alarms to monitor the aggregate state of your fleet based on pre-defined thresholds. For more information about fleet metrics, see Fleet metrics.
