New Notification, Other

🔖 Feature description

If you have a monitor and it is down, it might be interesting to see a change of the message / Problem.

Example 1: Push monitor, changes the error message
Example 2: HTTPS monitor, changes from DNS Problem to Status 50X problem

✔️ Solution

I would like to have an option to be notified during down status when the message changes.
It might even be interesting to be notified on a message change during up status for example for some push monitors.

❓ Alternatives

An alternative for the push notification option would be to have multiple monitors that only look at on problem at a time.

📝 Additional Context

• If you have a timeout notification for a monitor you might think it will be responsive again without the need to interact. If the error changes (e.g. to Error 500 on page), there will be no notification, due to the consistent down status, but it still would be good to know the change.
• If a push monitor sends "Problem x" as message and then the message changes to "Problem x and Problem y" it might be important to get an additional notification.

This is in some extend related to #1605 which promotes some kind of "info" or "warning" status option and the possibility to push changes in the message to the log without changing the status.

👍 +1 upvoting this as well. I, however, need it for up as well. I use push monitors as a way to send bits of data periodically. Something might trigger the hook, causing the monitor to be up. But I don't know what caused the trigger from uptime-kuma's perspective, so including the msg field and triggering updates would provide this to me "at a glance."

I was just coming to request this myself - I have a cronjob that updates my DDNS, if it fails, it sends an notification via Push monitoring - But I'd also like to be able send a notification if the IP has changed, so the service is still up, but has changed..

I would also like the MSG parameter to be logged/notified when it is different from the previous one, even if status remains up.
