AWS IoT SiteWise Messaging
Messages transport equipment data and computed data to, from, and within AWS IoT SiteWise. Messaging is metered by the number of messages ingested and retrieved by querying or publishing. A message can be ingested through an application programming interface (API)—a method allowing two software applications to exchange information, or generated by a computation over equipment data. A message can be retrieved when a property, such as a measurement of a sensor value, is published to AWS IoT Core as a notification or as a response to a query request.
Messages ingested through the API are metered in 1 KB increments. Messages published to AWS IoT Core are metered in 1 KB increments, and this operation does not incur any additional messaging charges from AWS IoT Core. Messages published in response to an asset property query request are metered for each set of up to 50 property values or every 4 KB of data contained in the message, whichever results in a higher count of messages. An interpolated asset property request is used to estimate and retrieve the values of missing data points in stored time series data. Messages published in response to an interpolated asset property query request are metered based on the number of property values retrieved from storage to compute each interpolated value. For example, when using the API to retrieve hourly linearly interpolated temperature data of a pump or a machine over a day, 48 property values will be retrieved from storage using 48 messages to compute 24 interpolated values.
Additional charges apply for GET requests made against your Amazon S3 bucket when data results are retrieved from your cold tier. For more information about these charges, see Amazon S3 pricing.
AWS IoT SiteWise Data Processing
You can create production metrics such as Operational Equipment Efficiency (OEE) using mathematical and statistical computations in AWS IoT SiteWise. Data Processed is metered by the number of computations run.
Transforms and Metrics: You can use a built-in library of operators and functions in AWS IoT SiteWise to create two different types of custom computations—transforms and metrics. AWS IoT SiteWise continuously computes each transform and metric whenever the underlying data is updated.
Auto-computed Aggregates: AWS IoT SiteWise automatically computes a set of commonly used aggregates such as average, sum, and count over multiple time periods (e.g., one-minute, one-hour) for equipment data, transforms, and metrics. For each message ingested, these aggregates are metered as a single computation.
AWS IoT SiteWise Data Storage
Once data is in the cloud, AWS IoT SiteWise stores equipment and computed data in a managed time series database that automatically scales with your data usage and storage. AWS IoT SiteWise monitors the size of your storage continuously to determine your storage charges.
AWS IoT SiteWise Data Export
You can export data from AWS IoT SiteWise into Amazon Simple Storage Service (Amazon S3). Data from your measurements, metrics, and transforms is exported as Amazon S3 objects periodically from AWS IoT SiteWise to Amazon S3. You will be charged for the number of S3 objects created or updated by AWS IoT SiteWise to export your data.
Additional charges apply for storing exported data in Amazon S3 and for PUT requests made against your Amazon S3 bucket. For more information about these charges, see Amazon S3 pricing.
AWS IoT SiteWise Monitor
SiteWise Monitor provides managed web applications for interacting with operational data from devices and equipment that send data to AWS IoT SiteWise.
AWS IoT SiteWise Edge
SiteWise Edge provides data collection and processing capabilities in the SiteWise gateway for local applications. SiteWise Edge capabilities are offered through packs.
Data Collection Pack: This pack enables data collection from common industrial data sources and transferring it to the AWS Cloud. You can collect data from OPC-UA servers, Modbus servers, and over Ethernet/IP. You can transfer the collected data to Amazon S3, AWS IoT SiteWise, AWS IoT Core, Amazon Timestream, and Amazon Kinesis.
The Data Collection Pack is free.
Data Processing Pack: This pack enables the processing of the computations (transforms and metrics) with AWS IoT SiteWise asset models and visualizing them with SiteWise Monitor web applications on the SiteWise gateway. You can also interact with the data processed locally by the SiteWise gateway using the same REST APIs you use with AWS IoT SiteWise in the cloud.
A Data Processing Pack is charged at $200 per active gateway per month. A gateway is considered active in a month if it connects to the AWS Cloud to receive SiteWise Edge software configuration updates.
Note that you will be charged separately for any other AWS services that you use; refer to specific pricing for those services. You will also be charged separately for AWS IoT Greengrass, which is used by SiteWise Edge.
AWS IoT SiteWise Alarms
The Alarms feature allows you to set up, visualize, and manage rule-based alerts to assess equipment behavior and identify equipment performance issues. Alarms in AWS IoT SiteWise are supported through the Alarms feature of AWS IoT Events. You will incur charges for alarms you create in AWS IoT SiteWise through AWS IoT Events. See AWS IoT Events pricing for details.
You will incur charges in AWS IoT SiteWise for publishing messages to AWS IoT Events that are used to evaluate alarms. You will also incur charges in AWS IoT SiteWise for storing alarm states received from AWS IoT Events.

Example 1
An industrial production line is sending data to AWS IoT SiteWise in the US East (N. Virginia) region. The production line includes 10 pieces of equipment, each of which reports one measurement every second. You configure AWS IoT SiteWise to collect this measurement data and upload to AWS. The monthly AWS IoT SiteWise charges are estimated as follows:Usage SummaryMessagingNumber of measurements per equipment = one measurement per equipment
Frequency of message ingestion = one message per second per measurement
Number of messages ingested in a month = one message / second / measurement * one measurement / equipment * 10 equipment * 86,400 seconds / day * 30 days / month = 25,920,000 messages per month

Storage per month = 25,920,000 messages per month * 150 bytes / message * 1 GB / (1024^3 bytes) = 3.62 GB per month*Auto-computed aggregates
SiteWise stores all auto-computed aggregates. The storage used by auto-computed aggregates depends on the number of aggregates and time intervals over which they are calculated. In the example above, six auto-computed aggregates calculated over three time intervals (one-minute, one-hour, one-day) will result in 0.37 GB per month of data stored. To learn more about how storage used by auto-computed aggregates is estimated, see this calculator.Storage from auto-computed aggregates = 0.37 GB per month*
Total data stored per month = 3.62 GB (from Equipment data) + 0.37 GB (from Auto-computed aggregates) = 3.99 GB per month*

Example 4
To example 3, you also add graphs. Using your custom application, you create a dashboard consisting of two graphs to monitor your equipment performance. On one of these graphs, you are monitoring raw data for your measurement retrieved using the GETAssetPropertyValueHistory API. On the other graph, you are monitoring five-minute linearly interpolated data for another measurement retrieved using the GETInterpolatedAssetPropertyValues API. Your application refreshes these graphs every 30 seconds, and your graphs show data over a one-hour window. The additional monthly usage and charges are estimated as follows:Usage Summary
Messaging
Your SiteWise monitor dashboard automatically refreshes every five seconds to help ensure that you are visualizing data close to real time. Assuming that you are monitoring graphs over a one-hour window, whenever the dashboard refreshes, all data points plotted on that one-hour window get refreshed. So, for each graph showing a one-minute aggregate, 60 total data points get fetched upon every refresh through messages. As each of these messages can carry 50 data points, the total messages retrieved can be estimated as follows:
Number of messages retrieved per refresh per graph = ceiling ((60 data points / refresh / graph) / (50 data points / message)) = two messages per refresh per graph
Number of messages retrieved across all graphs per refresh = two messages / refresh / graph * 10 graphs = 20 messages per refresh
Number of messages retrieved across all users per month = (20 messages / refresh) * (one refresh / five seconds) * 3,600 seconds / hour * eight-hour shift / day / user * 30 days / month * five users = 17,280,000 messages per month

On top of example 3, you also configure AWS IoT SiteWise to export data from measurements, metrics, transforms, and asset definitions to an Amazon S3 bucket in your AWS account. The AWS IoT SiteWise data export charges are estimated as follows:Usage Summary
Data Export
We will first calculate the number of objects that will be exported for measurements, metrics, and transforms. AWS IoT SiteWise creates a new S3 object for each measurement, metric, or transform that has data in the system every six hours.
Number of objects per measurement, metric, or transform per month = 1 object / 6 hours * 24 hours / 1 day * 30 days / month
Number of objects per measurement, metric, or transform per month = 120 objects / monthTotal number of objects for measurements per month = 120 objects / measurement / month * 1 measurement / equipment * 10 equipment = 1,200 objects per month
Total number of objects for metrics per month = 120 objects / metric / month * 1 metric / equipment * 10 equipment = 1,200 objects per month
Total number of objects for transforms per month = 120 objects / transform / month * 1 transform / measurement * 1 measurement / equipment * 10 equipment = 1,200 objects per month
Total objects per month = 1,200 + 1,200 + 1,200 = 3,600 objects per month
Billing SummaryAdditional Monthly Bill for data export
