I'd use the hobbitdboard query against the server:

DSLGWS="^server[12345]\$"
RESULT=0
bb 127.0.0.1 "hobbitdboard host=${DSLGWS} test=pusers fields=msg" | \
while read L
do
	NBUSERS=...whatever is needed to grab the number...
	RESULT=`expr $RESULT + $NBUSERS`
done

Grabbing data from the checkpoint file suffers from the fact that by
default it is only updated once every 15 minutes, so it takes a long
time for changes to filter through to that file. By using the
hobbitdboard command, you always get the latest data that Hobbit has.
