In Tanzu Observability by Wavefront, 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 Cloud Watch service properties or dimensions.
- To view and manage sources, select Browse > Sources.
- To filter and group in charts, use the Wavefront query language. You can filter by source and filter and group by source tags.
Examine Sources in the Source Browser
If you don’t see metrics in charts that filter by source, you can examine sources in the Source browser.
Step 1: Find a Source
When you select Browse > Sources the Sources browser offers many options to zoom in on the sources you’re interested in.
Filter sources by status. In contrast to metrics, sources are not excluded after 4 weeks of not reporting metrics, but you can filter sources by status.
Filter sources by tag. In most environments, administrators add source tags. You can add source tags from the UI or programmatically.
In the screenshot on the right, we've fitered by the tag wavefront.aws.billing and selected Recent Metrics (which shows as ok in the search bar).
Step 2: Examine the Source
When you select a source in the Sources browser, you can examinine it in more detail on a second page.
Hide and Unhide 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.
- In the Sources browser, all sources are included unless you explicitly exclude Obsolete sources.
- In the Metrics browser or Query Editor, sources that haven’t sent points for 4 weeks are no longer shown in the autocomplete dropdown. You can also manually hide sources by using the UI or API.
