Can I snooze a single check on a monitor?

Yes. Snoozing in Oh Dear is per check, not per monitor. That means you can silence "certificate expires soon" alerts on one monitor without affecting its uptime alerts, or vice versa.

How to snooze a specific check #

1. Open the monitor.
2. Click the check type you want to snooze (Uptime, Certificate Health, Broken Links, etc.).
3. Click Snooze. (The button reads Acknowledge when the check is currently failing, more on that below.)
4. Pick how long: 15 minutes, an hour, four hours, a day, until the next workday, or a week.

While a check is silenced, its runs still happen and its results are still recorded, so your history isn't interrupted. A snooze on a healthy check mutes everything until it expires; an acknowledgement of a failing check mutes the repeated down alerts but still sends the recovery, then clears itself.

Snooze vs. acknowledge #

The button changes with the check's state, and so does the behaviour:

• Snooze (the check is healthy): a preventive, full mute. Nothing fires until the timer runs out.
• Acknowledge (the check is failing): silences the repeat alerts for the incident you're already on, but the recovery still comes through and ends the acknowledgement.

For the full breakdown, including how this compares to maintenance windows, see the difference between snoozing, acknowledging, and maintenance periods.

Snooze vs. maintenance window vs. disable #

Easy to confuse, so here's the short version:

• Snooze / acknowledge: silence alerts on one or more checks for a set duration. Runs still happen, history is intact.
• Maintenance window: silence alerts for all checks on a monitor during a specific time period, and exclude any failures from your uptime percentage.
• Disable: stop the check from running entirely. No runs, no results, no alerts. Use this when you no longer want the check at all.

Rule of thumb:

• Just avoiding a short burst of noise? Snooze.
• Known downtime during a deploy? Maintenance window.
• Permanently not interested in this check? Disable.

Silencing directly from a notification #

Every alert email and Slack message includes a direct link to silence that specific check, picking 15 minutes, an hour, a day, or a week, without having to log into Oh Dear. Because you're acting on a live alert, this acknowledges the incident, so you'll still get the recovery when it clears.
