What is an Incident?

A data quality issue captured by Validio is called an Incident. There are different types of incidents. For example, an unexpected value in a table column is a different type of incidents than a schema change. In Validio there are four types of incidents:

• Validator threshold failure - A Validator's threshold has be breached.
• Source error - An error related to the communication between Validio and the data source.
• Schema change - The schema of a Source has changed.
• Segment limit exceeded - A Segmentation has exceeded the allowed number of segments. This limit is 1000 by default.

How to get notified about an Incident?

When an Incident occurs a Notification is sent, depending on the notification settings.

How to triage and troubleshoot Incidents?

The Incidents page aggregates all incidents from every Source. This page allows you to:

• Assign ownership and update the status of incidents during the triage process.
• Sort and filter incidents based on various criteria such as owner, status, and type, helping you monitor the progress of Incident resolution.
• Access detailed information for any incident by clicking on it, which takes you to its Incident details page.

In addition to the Incidents page, it is also possible to overview, triage and troubleshoot Incidents from other pages, such as:

• Incident detail - View and manage a specific Validator threshold failure Incident.
• Sources - Overview all Incidents for all Sources.
• Validators - Overview all Incidents for a specific Source.
• Validator details - Overview all Incidents for a specific Validator.

Note that the Incident details page currently only exists for Incidents of type Validator threshold failure.

Recommended approach

We recommend the following approach to triage and troubleshoot an incident:

1. Make sure to have Notifications set up, so that you are notified when an Incident occurs. Using the link in a Notification, you can navigate straight to the Incident details page.

   You can also navigate to the Incident details page from the Incidents page, or the Validator details page.

2. Assign an Owner and a Status to the Incident, as described on the Incidents page. Make sure to continuously update Owner and Status, according to your ways of working, throughout the whole triaging and troubleshooting process.

3. When troubleshooting an Incident, it is very helpful to view the Debug tab for relevant information. It is also helpful to view the Validator details page page, to get more contextual information about the Incident, such as information about Threshold types, Segmentations and viewing the behavior of adjacent datapoints in the graph.
