Hi,
Your connection ${NAME} has changed its state to ${STATE}
on ${HOSTNAME} at ${DATE}.
Following parameters were passed:

device = ${DEVICE}
sourceip = ${SRCIP}
host = ${HOSTNAME}
warn_email = ${WARN_EMAIL}
Packet statuses:
replied = ${REPLIED} packets replied
waiting = ${WAITING} packets waiting for reply
timeout = ${TIMEOUT} packets that have timed out (= packet loss)
reply_late = ${REPLY_LATE} packets that received a reply after timeout
cons_rcvd = ${CONS_RCVD} consecutively received replies in sequence
cons_wait = ${CONS_WAIT} consecutive packets waiting for reply
cons_miss = ${CONS_MISS} consecutive packets that have timed out
min_rtt = ${MIN_RTT} [usec], from received packets
avg_rtt = ${AVG_RTT} average rtt [usec], calculated from received packets
