As I've mentioned in my books, if a number of logs decreased drastically, it might not indicate that reportee host got healthier drastically.

Both increasing and decreasing of log amount are supposed to be taken care. I've forgotten the rule, sigh...

Observe how the log message amount changes periodically, so that you can detect a drastic increment or decrement of messages.
