Forgive me if this is simple. We use many APC UPS devices which send an snmp trap when the batteries are going bad. I want to setup an alert to send an email when this trap is received. I only want to send one email in a 24 hour period. The problem is that the email is sent for the first UPS with a battery issue, the 2nd or 3rd UPS with an issue is suppressed. What I really want is one email per device per 24 hour period. Thoughts?
