UserParameter=ntp.peer.stratum,(/usr/bin/ntpq -pn | /usr/bin/awk 'BEGIN { stratum=99 } $1 ~ /\*/ { stratum=$3 } END { print stratum }')
UserParameter=ntp.peer.count,(/usr/bin/ntpq -pn | grep -E -c '^\*|^\+')
UserParameter=ntp.peer.ip,(/usr/bin/ntpq -pn | /usr/bin/awk 'BEGIN { peer=NONE } $1 ~ /\*/ { peer=$1 } END { print substr(peer,2) }')
UserParameter=ntp.time.offset,(/usr/bin/ntpq -pn | /usr/bin/awk 'BEGIN { offset=1000 } $1 ~ /\*/ { offset=$9 } END { print offset }')

So können die items ausschauen

ntp.time.offset	
ntp.peer.stratum
ntp.peer.ip
ntp.peer.count
