Sources | VMware Aria Operations for Applications Documentation

Learn about sources and how to manage them.

In VMware Aria Operations for Applications (formerly known as 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 an Operations for Applications 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.

While every user can view sources, you must have the Source Tag permission to manage sources. If you don’t have the permission, the UI menu selections, buttons, and links you use to perform management tasks are not visible.

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.

Note: The Sources browser doesn’t filter out the obsolete sources.

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.

Obsolete—Sources that didn't emit metrics for a certain period of time (obsolescence period). (Maps to ~status.error.)
Note: You can see your current configuration by looking into the Advanced settings of any chart or dashboard. To change this configuration, contact Technical Support.
Recent Metrics—Sources with metrics received in the last 2 days. (Maps to ~status.new and ~status.ok.)
Metrics Stopped—Sources with no metrics received in the last 2 days. (Maps to ~status.stopped.)

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 filtered 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 Show 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 and Query Editor, obsolete sources are no longer shown in the autocomplete dropdown. You can also manually hide sources by using the UI or API.

Note: While hidden sources are removed from the autocomplete dropdown, you can still use these sources in ts() queries when data values are present.

To hide one or more sources:

Select Browse > Sources.
Select one or more sources and click Hide.

To view hidden sources

Select Browse > Sources.
Use the toggle in the top right of the Sources browser.

Add and Edit Source Descriptions

Source descriptions are a great way to add details, such as the role, availability zone, or running applications, to a source.

To add or edit a source description:

Select Browse > Sources.
Select a source.
Click Add a Description.

All users can now view the description.
