I have a custom client running on a z/VM system with the hobbit server

for my host be modified to record and report on that finer interval
without altering the setups for all the other hosts that are being
monitored?
You would have to create a custom RRD file by hand, but once it's been
created Hobbit should update and graph it OK. Check the "rrdcreate"
man-page from RRDtool for details, but a command like this should do
get you started:
rrdtool create la.rrd -s 60 \
DS:la:GAUGE:120:0:U \
RRA:AVERAGE:0.5:1:2880 \
RRA:AVERAGE:0.5:6:2880 \
RRA:AVERAGE:0.5:24:2880 \
RRA:AVERAGE:0.5:288:2880
The "-s 60" means that data arrives every 60 seconds, and the "120" in
the second line means that there cannot be more than 120 seconds between
updates for the data to be valid.
