EvmEvent(5) EvmEvent(5)
• Each posted event receives an unsigned integer event identification number, with a value greater by
one than that of the previous event posted through the same EVM daemon.
• The event identifier of the first event posted after the daemon is started or restarted is zero.
• The event identifier wraps back to zero after it has reached its maximum value.
• If a daemon receives an event that already contains an identifier, it does not generate a new identifier
for the event.
• New event identifiers are assigned only to events which the daemon validates and accepts for distribu-
tion.
• If an event is accepted and does not already contain an identifier, a new identifier is assigned to it
even if there are no subscribers for the event.
Event Priority
EVM uses an event’s priority value solely for filtering, sorting and presentation purposes - it does not use
it to prioritize the distribution sequence. The priority is an integer value in the range 0-700, with zero
being the least significant priority. This table indicates the event priority, the default action taken by
evmlogger for that priority, and a description of the priority.
