#%s DONT_STORE_ZERO_ENTRIES
#%s USE_DAEMON_IP_FILTER
#%s USE_PREPARED_STATEMENTS

Stores average values in the MySQL database as specified in the supplied
configuration file. This file gets reloaded on every write, so you can switch
databases on the fly if you wish.

The configuration file must look like:
  storage_host=HOSTNAME
  storage_port=PORT
  storage_user=USERNAME
  storage_pass=PASSWORD
  storage_dbase=DATABASE

Only counts for IP addresses that are listed in the `ip_range_tbl` table are
stored. Those ranges can be specified on a `node_id` basis if desired. See
the storage.sql CREATE script for more information.

When DONT_STORE_ZERO_ENTRIES is defined, no values with all zeroes are stored.
For calculation purposes no value is the same as all zeroes anyway. But if
you're interested in seeing whether there has been _any_ traffic at all, you'll
want to undefine it.

Define or undefine USE_DAEMON_IP_FILTER to select whether you want to do the
filtering of the IP addresses in ip_range_tbl by the daemon or by the SQL
server respectively. Filtering by SQL is probably only better if you have
really many or very large IP ranges (covering 10+ percent of the entire IP
space).

You can define or undefine USE_PREPARED_STATEMENTS to enable/disable use of
MySQL prepared statements. Using them is recommended as it reduces the amount of
traffic sent to the server and the server only has to parse the query once.
