public class InvocationPlugin extends DiagnosticsPlugin
DiagnosticsPlugin
that displays all invocations that have been
executing for some time.
It will display the current invocations and the invocation history. For
example, if an entry processor has been running for 5 minutes and the
SAMPLE_PERIOD_SECONDS
is set to 1 minute, then there will be
5 samples for that given invocation. This is useful to track which
operations have been slow over a longer period of time.

If a monitor should run only once, a negative value is returned. This is
useful for 'static' monitors like the SystemPropertiesPlugin
that run at the beginning of a log file but their contents will not
change.
