Request for clarification on Triggered Alerts

Hi Team,

Greetings!

I hope you are all doing well. I have a few questions about active alerts and their working behavior. Please refer to the snapshot below for your reference.

1. In points no.1, 2, 3 & 4 it's showing alert active time is 60d 22h 55m, I want to know why it's showing like this as the issue is already resolved.

2. In Point no. 5 it's showing alert active time is 114d 9h 57m, I want to know why it's showing like this as the issue is already resolved and the alert is also acknowledged.

3. In Point no. 6 it's showing alert active time is 115d 2h 54m, I want to know why it's showing like this as the issue is already resolved and the alert is also acknowledged.

4. Please explain how triggered alerts work and when an active alert is displayed, regardless of whether the issue is resolved.
