It's up for a long time but the alert just triggered today.
Please help to spread knowledge on why does this happen and how do we stop or prevent those misfired alerts
Hi
Looks like those alerts triggered more than a year ago and not today. Looking at "active time", thats more than a year.
The alerts should reset if the interfaces are up. Look at the alert rule and the tab "Reset condition". Can it be something there that caused the alert not to reset?
Sometimes I have seen that alerts don't reset at all. Then you can mark the alerts and press "Clear triggered instance of alert", that you have in the menu on you picture. This can happen if you have already triggered alerts and then change the alert rule.
