Validation Session Monitor
Overview
The Validation Session Monitor provides real-time and historical visibility into Validation scenario executions. Users can track running validations, review passed and failed sessions, inspect execution logs, and access the full execution summary — all from a single consolidated interface.
Prerequisites
- You are logged in to Data Trust with a Pro-User or Admin Pro-User role.
- At least one Validation scenario has been executed or is currently running.
Steps
Path: Data Trust › Scenario Session Monitor › Validation Session Monitor
Navigate to the Scenario Session Monitor module and select Validation Session Monitor from the left sidebar. The page loads listing all recent validation scenario sessions with their names, statuses, and execution timestamps.
The toolbar provides Refresh to reload sessions, Export to CSV to download the session list, and Search to locate a scenario by name. Export is especially useful for compiling validation run history into compliance or audit reports.
When the session list exceeds the default page size, a Load More button appears at the bottom. Click it to load additional sessions incrementally without resetting the current view or losing scroll position.
Click any scenario name in the session list to open its execution detail. For passed sessions, the detail confirms that all validation rules evaluated successfully within the defined thresholds.
Clicking the Edit icon opens the Validation Scenario Edit page showing the full rule set, data source, and threshold configuration. Use this page to understand the validation logic that was applied during the session you are reviewing.
The Log button in the session detail opens the execution log for that specific validation run. Logs are the fastest way to understand processing flow — they show each rule evaluation step with timestamps and any warning or error messages.
The Log popup displays the complete execution log with step-by-step messages for the selected validation run. Scan for lines marked ERROR or WARNING to pinpoint exactly where the scenario deviated from expected behaviour.
Clicking the Copy icon in the Log popup copies the full log text to the clipboard and displays a Text Copied Successfully confirmation. Paste the copied log into a ticket, email, or support request to provide complete diagnostic context without manual transcription.
The Execution Progress button shows a real-time progress indicator for scenarios that are actively running. Click it to open a progress panel showing the percentage complete and the current processing stage.
The Validation Execution Summary displays a rule-by-rule breakdown of pass, fail, and warning counts for the selected session. Use this summary to identify which specific validation rules triggered failures and prioritise data quality remediation work.
The Running tab filters the session list to show only validation scenarios that are currently executing. Monitor this tab during batch runs to track live validation progress and catch failures as they occur.
The Passed tab shows all validation sessions where every rule evaluated within the defined acceptance criteria. Review this tab periodically to confirm that expected validations are consistently passing over time.
The Failed tab lists validation sessions where one or more rules produced a failure result. This is the primary triage queue for data quality issues — click into each failed session to access the execution summary and identify the failing rules.
The Errored tab shows sessions that could not complete due to a system or configuration error, distinct from a rule-level failure. Check the session log for errored sessions to determine if the issue is a connectivity problem, missing data, or an invalid scenario configuration.
