Have a way to mute alert until it's resolved to receive a resolved notification once it's fixed

Let's say I have an outage on one of my server I'm monitoring and it's inaccessible but I don't know how long it's gonna take to fix it, so I'm muting it for a really long time.

With this approach, I won't receive any resolved notifications, so to check if the alert is fixed I need to go to my alerts list to see if it's still firing, and given that I've muted it for a long time I also need to remove the mute to know if it's firing again.

What would be nice to have:

• I have a server outage
• an alert is triggered
• I create a new mute and somehow specify that I need it to be active until the alert is resolved
• a server fixes itself
• a resolved alert notification is dispatched
• a mute is removed
• if a server starts misbehaving again and a new alert is triggered, I'm receiving an alert notification again

Pretty sure this would have a lot of cases that'll make it difficult, like if a mute has a lot of active alerts, but still would be really awesome to have.

Do you guys think it's manageable?

Start by reviewing Alertmanager's mute lifecycle and how resolved notifications are dispatched. Define how a mute should end when its alert resolves, including behavior for multiple active alerts, then identify the relevant implementation and tests before proposing a design.
