Hello Adrian, if the host for which you send gmetrics is not a gmond "client", you need to also spoof a "heartbeat" metric, else the collector will think the host is down :
HOST=ups.example.com
IP=$(getent hosts $HOST | cut -d" " -f1)
GMON=/etc/ganglia/gmond.UPS.conf
T=$(ping -qn -c 1 -w 6 $IP | grep rtt | cut -d/ -f 5 | sed s/\\.//)
if [ "$T" ] ; then
gmetric -c $GMON -n ping_time -t uint32 -u us -x 600 -d 7200 -g network -T
"ping avg time" -H -S ${IP}:${HOST} -v ${T}
....
(your custom gmetrics follow here)
and of course in the gmond.UPS.conf you put your separate "collector" gmond
host and port.
For the collector host, I run separate "client" gmond and multiple "collector"
gmond. The latter have separate config files with no "udp_send_channel", in
this way they don't send to themselves their own host metrics.
I think I posted on the list my "gmondsrv" init.d script last year or so...
mail me if you don't find it.
Cheers,
Sergio
