Alert check based on date

Hi support,

For some specific ports, I want to be alerted if the "ifLastChange" has been updated.

I have though about creating an alert checker for ports with parameter "ifLastChange" :

• If different from previous check (but seems impossible with an alert checker)
• If ifLastChange date is lower than current date less 5 minutes (same thing seems impossible with an alert checker)

Is there a way to make this possible ?

Thanks
