Did some more investigation and it seems like the if_matched_group is
still only agent dependent, meaning even after rule 100001 records in
alerts.log 10+ times from 5 different agents, the alert doesnt flag
until its 6 times from the same agent (obviously with the same source
ip). Seems like the logic in Ossec is broken.
