Global Sources page with data quality tooltip

You can use the global Sources page to review and manage all the sources you have access to in Validio. The page includes a Data Quality graph with incidents histogram and list of 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.

Data Quality Graph

The Data quality over time graph displays the data quality score over the selected time range, a histogram of the severity of the detected incidents, and a count of the incidents for each severity. You can hover over the graph to see more information for each datapoint and bar.

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.
Priority	The importance (Critical, High, Medium, Low, None) of the source. Any incidents detected on this source will inherit this priority if the validator does not have a priority.
Owner	The user responsible for the source.
Latest poll	How long ago data was last polled from the source. Displays an error if the last poll failed.
Latest window	How long ago data was last seen from the source.
Tags	Tags assigned to the source.

Status

Possible statuses are:

Status	Description
Initialized	The Source is created but has never been started.
Running	The Source is activated and able to process data.
Polling	The Source reads data. This is only allowed from a running state.
Idle	The Source is stopped and is in an idle 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.
Resetting	The source is resetting. Resetting a source is equivalent to deleting it, then creating a new source with the same configuration, and finally backfilling all its validators.

Filter and Sort

Filter sources by searching for Name, or picking Type or State. You can sort Sources by clicking on a column, for example Quality.

Manage a Source

Click on ⋮ menu to access options for managing sources:

Options	Descriptions
Start	Start data validation on the source.
Stop	Pause data validation on the source.
Poll	Read data from the source.
Backfill	Validate historical data that has not yet been validated. The amount of historical data is configured for warehouse sources.
Rename	Rename the source.
Reset	Resetting a source is equivalent to deleting it, then creating a new source with the same configuration, and finally backfilling all its validators.
Update Credential	Update the Credential used for the Source.
Update Config	Update the Source configuration.
Delete	Remove the Source from Validio.

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.

Reset

Resetting a source is equivalent to deleting it, then creating a new source with the same configuration, and finally backfilling all its validators.

These are some common scenarios when it can be useful to reset a source:

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