3.4Mute and snooze

To mute a monitor is to keep it checking but hold its "down" alert. Mute it while you fix a problem you already know about. To snooze is to mute until a set time. A snooze ends on its own.

Mute or snooze a monitor#

1. Open the monitor and select Mute ▾.
2. Choose Mute for 1 hour, Mute for 4 hours, Mute for 24 hours or Mute indefinitely.
3. A badge appears next to the monitor's name. A snooze shows the time left, for example muted 4h. Hover over it to see when it ends. An indefinite mute shows muted.
4. To end a snooze early, select Unmute now. To end an indefinite mute, select Unmute.

While a monitor is muted:

• Checks run and results are recorded as usual.
• An incident still opens and appears in incidents, but the "down" alert is held.
• If the monitor is still down when the mute ends, the held "down" alert is sent. If you select Unmute, it is sent at once. If a snooze runs out, it is sent at the next failed check.
• Reminders are not sent. A reminder that comes due while muted is dropped. It is not sent later.
• No acknowledgement notice is sent when someone acknowledges an incident.
• TLS certificate expiry warnings are recorded but not sent.
• When the monitor recovers, the "resolved" notice is sent. It says the outage was not paged.

A snooze ends at its set time, even if no check runs at that moment.

Mute and snooze with the API#

Call UpdateMonitor with one of these bodies:

muteUntil is a date and time in RFC 3339 format, in UTC. RFC 3339 is the standard YYYY-MM-DDTHH:MM:SSZ form shown above.

• "muted": true on its own keeps any end time that is already set. The dashboard's Mute indefinitely always clears it.
• In the dashboard, a snooze lasts 1, 4 or 24 hours. With the API, you can choose any end time.
• To read the state, look at muted and muteUntil on the monitor. muted: true with no muteUntil means muted until you unmute.
• A monitor can still show muted: true with a muteUntil in the past. Treat it as unmuted.
