Detect continuous logs with the same pattern via syslog module

Hello,

Your help to improve the syslog alert module. For example, I have the scenario where is common the customers go down frequently during the day but I need to detect when more than 5 customers go down simultaneously or in a specific time interval, it could be 5 minutes.

Feature like this is very interesting, others monitoring tool doesn't have it.

Thank you in advance for your support.
