The events table can grow rapidly. Running the table administration program,
rmstbladm, with the -c option removes old entries. This should be done periodically
using a cron script. See Page 5-44 for details. The data-lifetime attribute in the
attributes table (see Section 10.2.3) determines how old the entries must be before
they are removed.
Events are discussed in detail in Chapter 8 (Event Handling).
10.2.7 The Event Handlers Table
The event_handlers shown in Table 10.11, defines the handler scripts that are run in
response to events. Event handling is discussed in detail in Chapter 8 (Event Handling).
