Overview

After removing a Custom Property that was previously used in the All Active Alerts dashboard (including Global Filters), the dashboard query may fail and not regenerate automatically.

Users may experience:

  • Dashboard table not loading

  • Global Filter not working

  • Error in Alerts & Activity → Alerts (New UI)

  • RunQuery failure referencing a missing Custom Property (e.g., ResponsibleTeam)

Cause

When a Custom Property is deleted:

  • The underlying SWQL query used by the All Active Alerts dashboard still references the removed property.

  • The widget configuration retains stale metadata.

  • The query engine cannot resolve the property from Orion.AlertConfigurationsCustomProperties.

  • The dashboard does not automatically regenerate its query schema.

Resolution

A fix for this issue is planned for a future release of the SolarWinds Platform. Watch this article for updates. In the meantime, use one of the workarounds below.

WORKAROUNDS:

Option 1: Recreate the Custom Property

  • Recreate the deleted Custom Property (same name and type:Alert).
  • This allows the existing query to resolve successfully.

Option 2: Use Legacy Alerts UI

Switch to the Legacy Alerts View as a temporary workaround if the New UI continues to fail.
