How would one write a rule that checked if say Message has been inserted
into the stream 10 times over the last 30 days?

You can use an accumulate function.

You need
dialect "mvel"
in your rule, or you will have to use Javabean-style code in the RHS,
i.e. $x.setTotalCount( $y ).
This said, the rule is not correct for many reasons:
1) technical: $ticket is scoped within the accumulate, and can't be
accessed externally
2) event semantics: events are immutable and are not supposed to be modified
3) modelling: it does not look right to keep the total counter in (each
individual) ticket.
(also, updating the ticket may cause unwanted recursions)
I'd create another class:
when
$x: TicketStats()
accumulate( $ticket : Ticket() ... )
then
modify ($x) { setTotalCount( $num ); }
end
