[Xymon] Monitoring multiple values

[Jeremy Laidman]

Ralph's suggestion looks very interesting, and means you can have it apply
to any and all clients without having to make changes to each one.

In case you can't get it working for some reason, I think something
client-side like the following might work:

#!/bin/sh
die() { echo "$@" >&2; exit 1; }
[ "$XYMON" -a "$XYMONSRV" -a "$MACHINE" ] || die "Please run within a Xymon
environment"
VALUES=`get_values`  # gets 5 numbers
set - ""$SAMPLES
[ $# -eq 5 ] || die "Value count $# was not 5: $VALUES"
SLEEP=0
DELAY=60 # 300/5+1
for VALUE in $VALUES; do
    MSG=`printf "data $MACHINE.trends\n[filename.rrd]\nDS:dsname:$DELAY:U:U
$VALUE\n"`
    ( sleep $SLEEP; echo "$MSG" | $XYMON $XYMSRV @ ) &
    let SLEEP=$SLEEP+$DELAY
done

This should fire off 5 background tasks, each waiting a multiple of 60
seconds before sending in their value to the RRD collector, thus staggering
the updates across the next 5 minutes.
