1. Last account update age in hours
2. Account balances
The plugins have been in use for several months now and warn
when the balance of accounts drop below a configurable value,
and when Hibiscus stopped updating data because a TAN needs to
be entered manually after 90 days.
The plugins directly query the MySQL database of a Hibiscus server
instance.
