I set an alert condition for an IP. The condition is to send alert when there are 3 incidents over 2000ms in the last 6 pings. Max email frequency is 30 min and the duration to wait for worse condition is zero. However, I sometimes received alerts in which the most recent 6 pings, as it showed in the alert email, are below the threshold. What settings did I make it wrong to create this false alerts? <br><br>
