Use Stream Metrics
When a Data Stream is published, the Stream Metrics becomes visible and allow you to view the amount of data and errors that are being processed per minute in the Data Stream and the number of active Stream Hosts per Collection.
It is recommended that you read the article listed below to improve your understanding of Stream Metrics.

Stream Metrics Components

The Stream Metrics has three parts: Stream Load, Stream Errors, and Stream Hosts per Collection.

Stream Load

Stream Load represents the amount of data that is being processed by the agents in the Data Stream. The left side of the Stream Load card shows the amount of data that has been processed in the last minute and the right side has a sparkline with a 5-minute history. Hovering over the sparkline will display the amount of data that was processed for the selected minute.

Stream Errors

Stream Errors represents the number of errors that are being generated by the agents in the Data Stream. The left side of the Stream Errors card shows the amount of errors that are generated in the last minute and the right side has a sparkline with a 5-minute history. Hovering over the sparkline will display the number of errors that were generated for the selected minute.

Stream Hosts per Collection

The Stream Hosts per Collection card shows the name and the number of active Stream Hosts in each Collection. If the Data Stream has objects that are in different Collections it will show a card for each Collection.
