I installed Log Sentry and I am mostly pleased with it, however, I am getting an abnormal amount of emails. For example, from Friday morning to Monday morning, I received 220 emails for one server. If I multiple that by six, then I have to review over a thousand emails for a weekend period. I have noticed that most of the entries are acceptable, from IP addresses that are trusted. Is there a way to filter what Log Sentry enters in the log or change the timing of the emails?

Change the cronjob settings. If my memory serves me well the initial setup sends an email every 15 minutes. If you change that to an hour or more you'll see a significant reduction

How about filtering out entries?
