What is a maintenance window (blackout) in NPM?

• A. A period during which alerts are suppressed to avoid noise
• B. A time period when alerts are raised more aggressively
• C. A feature to schedule backups
• D. A dashboard filter

Answer: (D)

A maintenance window (blackout) in NPM is a period when alerts are silenced to prevent noise during planned downtime or changes. This is essential for avoiding a flood of alerts when you’re doing maintenance, updating devices, or performing actions that you know will trigger alerts but are under your control. You can schedule these windows for specific devices, groups, or globally, and they can be one-time or recurring. While data collection continues, the alerting engine does not generate or escalate alerts during the blackout, keeping on-call activity focused on real issues. It’s not about backups or how dashboards are displayed; it’s specifically about suppressing alerts during defined times.
