The catalog is the place where you can get detailed information on any of your data assets connected to Sifflet.

Main page

The data assets can be displayed either as icons or list. The desired view can be selected at the top-right corner of the page.

On both views, you will have access to the name of the asset, the source where it is stored as well as the description of the asset, either automatically extracted from your datasource or manually edited by your team.

Finally, if using the icon view, on the top-right corner of every icon, you can see a coloured dot next to your asset name. It represents the monitoring status.

The colour code is the following:

Grey: The table is not being monitored. It applies to any table with less than 3 running data quality rules.
Red: Sifflet detected a critical data quality issue. It applies to any table with 3 or more running rules when the last execution of a critical rule has failed.
Orange: Sifflet detected a data quality issue that requires the user's attention. It applies to any table with 3 or more running rules when at least one rule execution has failed in the last 5 weeks (except when it is the last run of a critical rule, in which case the status is red).
Green: The table contains reliable data. It applies to any table with 3 or more rules when all past executions of all rules in the last 5 weeks have succeeded.
