# This script checks for consistency between the event filesystem and
|
||||
# the database. If events are found in one and not the other they are
|
||||
# deleted (optionally). Additionally any monitor event directories that
|
||||
# do not correspond to a database monitor are similarly disposed of.
|
||||
# However monitors in the database that don't have a directory are left
|
||||
# alone as this is valid if they are newly created and have no events
|
||||
# yet.
