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.

Polling	The Source reads data. 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.
