now i make a test with some debug informations. The line "echo ...."
exists twice. The second line give his output via ">" to a file. And
this file was written with date, when the daemon run.

and hello Pavel!

The scrist looks now so:


HOSTNAME="${COLLECTD_HOSTNAME:-`/bin/hostname -f`}"

while sleep "$INTERVAL"
        TEMP=$((/usr/bin/sudo /usr/bin/ipmitool sensor get 'System Temp'|/bin/grep Reading|cut -d " " -f 12) 2>/dev/null);
        if [ $? -ne 0 ]
        /bin/echo "PUTVAL $HOSTNAME/exec-ipmi/temperature interval=$INTERVAL N:$TEMP"


But nothing change... no data at the server sided collectd.
