You can create a Safeguard on one or multiple targeting rules within a Feature Gate. To create a Safeguard on a rule, follow the steps below:
  1. Go to a Feature Gate’s Setup tab
  2. Pick a targeting rule for which you want to monitor regressions
  3. Click the three-dot (…) menu and choose ‘Safeguard Rule’
    Create Safeguard on a rule
  4. Choose the action to take when alerts fire:
    • Rollback to 0% - Assign Default value to all users
    • Roll out to 100% - Assign Pass value to all users
    • Pause Rollout - Stop scheduled rollout progression (only available with active Schedule Rollout policy)
    Select an action
  5. (Optional) Set how long to monitor alerts for safeguarding the rule:
    Alert typeEvaluation periodEvaluation start time
    Topline alertChoose your ownStarts when the safeguard is created
    Rollout alertFixed (90 days)Starts whenever targeting rule’s pass % changes
    Set evaluation period
    Recommended: Ideally you want to monitor topline alerts for crashes, errors, latency, etc. for a few days after a Feature Gate rollout to make sure things are stable. We recommend starting with a 14-day evaluation period.
  6. Select one or more alerts to monitor:
    • Rollout alerts - For feature-specific regression detection
    • Topline alerts - For system-wide health monitoring
    Add alerts for your Safeguard
  7. Click Save
