More flexibility for maintenance mode in Grafana IRM

Maintenance mode in Grafana IRM now gives you finer control during planned work, with three alert behaviors and any custom end time you need.

When you enable Maintenance mode on an integration, choose how IRM handles incoming alerts:

• Silence escalations. Alerts stay visible in IRM, but escalation chains pause. Useful when you’re testing templates or troubleshooting an integration.
• Group alerts. IRM collects every incoming alert into a single maintenance alert group instead of paging individually. Useful for planned windows when you expect a burst of alerts from the same root cause.
• Disable alerts (new). IRM drops incoming alerts at ingestion. Useful for major infrastructure changes where the noise isn’t actionable.

Alongside the existing presets (1, 3, 6, 12, or 24 hours), you can now set any custom end time, so you can cover multi-day migrations and deploy-aligned windows.

Existing maintenance windows continue to work without changes.
