[collectd] Plugin Exec generate no data

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:

#!/bin/bash

HOSTNAME="${COLLECTD_HOSTNAME:-`/bin/hostname -f`}"
INTERVAL="${COLLECTD_INTERVAL:-60}"

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

done

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

Greetings...
