Hi,
Disman is evaluating the condition (see for details snmpd.conf man page)
every interval defined there and sends a trap first time the condition is
met (as opposed to first time it is evaluated). Next trap will be sent only
if condition becomes FALSE and then TRUE again. That is the base for
providing "raising" and "falling" functionality. Basically you need to
define two triggers with thresholds to implement both RisingAndFalling. As
you can see, it is not always important if the trigger evaluates conditions
on the agent startup. It becomes even less significant if the intervals are
short (5-10 sec or so).
In some specific cases I could not use disman... Ended up defining special
traps and implementing their specific requirements in special functions (see
send_XXX_trap() function)
Regards,
Alex
