What is a telemetry chart?

Telemetry charts

A telemetry chart plots historical information if available, then streams real-time data on the same chart.

For example, you can configure a chart to plot data from the last 12 hours, followed by current data. This information can be useful in assessing changes.

Note: Historical data must be available; that is, data must have been collected and retention polices must allow for the data to remain in the database.
