Maintenance windows
Maintenance windows tell HostAtlas “expect noise here — don’t page anyone.” Monitoring keeps running; alerts and notifications are suppressed for the scope you choose, then automatically resume when the window closes.
What you see
Section titled “What you see”Under Alerts → Maintenance (or /maintenance) you get a table of windows:
- Title and optional description.
- Scope: a single server, a group of servers by tag, or the entire fleet.
- Start / end times (UTC and local).
- Status badge: scheduled, active, or ended.
- On / off toggle.
Active windows are highlighted; the servers they cover show a small “under maintenance” chip on the Servers list and on the server detail page.
What you can do
Section titled “What you can do”- New window — pick scope, start, end, title. Optional: a note for the audit log.
- Edit — reschedule or change scope on an existing window.
- Toggle — flip a window off without deleting it (useful for one that’s on the calendar but no longer needed).
- Delete — removes the window; any suppression it was providing ends immediately.
How it works
Section titled “How it works”- While a window is active, every alert rule that would target a server inside its scope is silenced. The rule still evaluates, an event may still be recorded internally for context, but no notification goes out and no incident is opened.
- Suppression starts and stops automatically at the window’s timestamps — you do not need to press anything at start or end.
- Maintenance status is visible everywhere the affected servers appear, so operators can see at a glance why a normally-loud host is quiet.
- Scope options:
- Server — one host.
- Tag — every server carrying a given tag.
- Global — every server in the workspace (use sparingly).
