You can use the Sources page to review and manage all the sources you have access to in Validio. The page include an incidents histogram, which summarizes incidents for all of your sources. You can filter and sort the list of sources, add a new source, manage (such as backfill, reset, update the credential for, and more) a source, or click a source to navigate to its details page.

Incidents Histogram

An incidents histogram summarizing all your Sources. For more information, refer to the Incidents page.

Add a New Source

Click on + New Source to start the source configuration wizard. You can find instructions to connect Validio to each source on their dedicated pages.

List of Sources

Immediately in the source list you see the following information:

Column Name	Description
Name	Source name. Click a Source name to navigate to its Source details .
Status	The current status of the Source, such as Running or Polling. For the full list, see Status.

Quality	Quality is a calculated as number of Windows without incidents / total number of Windows.
Namespace	The namespace assigned to the source.

Status

Possible statuses are:

Running	The Source is activated and able to process data.
Polling	The Source reads data. This is only allowed from a running state.

Pending backfill	User has requested to backfill one or more Validators.
Backfilling	The Source backfills historical records. This is only allowed from a running state.

You have changed sensitivity on a dynamic threshold and want to re-validate all historical data with the new sensitivity.
