Learn about sources and how to manage them.

A source is a unique application, host, container, or instance that emits metrics. The source is explicitly set in the source field of a Wavefront data format metric. For AWS integrations, the source is extracted from AWS service properties or dimensions.

Wavefront Query Language supports filtering by source and filtering by source tags.

To view and manage sources, select Browse > Sources.

Hiding and Unhiding Sources

With more and more companies using dynamic services such as AWS, it’s typical to have sources constantly being spun up and shut down. When applying source filters to the Metrics browser or a ts() expression, this can lead to several sources being included in the autocomplete dropdown even when they are no longer reporting data. After 4 weeks of inactivity we remove those sources from the autocomplete dropdown, but you can also manually hide them from the UI or API.

Note: While hidden sources are removed from the autocomplete dropdown, those sources can still be used in a ts() query when data values are present.

To hide one or more sources:
  1. Select Browse > Sources.
  2. Select one or more sources and click Hide.

To view hidden sources
  1. Select Browse > Sources.
  2. Use the toggle in the top right of the Sources browser.
