Hey thanks a bunch for sharing. Very nice script!

Hi folks,
to monitor the 5 minute average cpu-speed of your notebook or server
capable of changing its cpu speed you can use the folling bits:
CLIENT:
Place cpuspeed.sh in the clients ext-directory:
cpuspeed.sh (requires bash, awk and loaded cpufreq_stats.ko)
#!/bin/bash
COLUMN=cpuspeed # Name of the column
COLOR=green # By default, everything is OK
MSG=""
STATEFILE="/sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state"
SPEEDS=`awk '{print $1}' $STATEFILE`
for SPEED in $SPEEDS; do
export TICKS$SPEED=`grep $SPEED $STATEFILE | awk '{print $2}'`
done
sleep 300
for SPEED in $SPEEDS; do
export TICKS${SPEED}_2=`grep $SPEED $STATEFILE|awk '{print $2}'`
done
for SPEED in $SPEEDS; do
DIFF=$[TICKS${SPEED}_2 - TICKS$SPEED]
DIFFSUM=$[$DIFFSUM + $DIFF ]
if [ $DIFF -gt 0 ]; then
CLOCKS=$[$CLOCKS + ($DIFF*$SPEED) ]
fi
done
RESULT=$[$CLOCKS/$DIFFSUM/1000]
MSG="Mhz:$RESULT"
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR `date`
${MSG}
"
exit 0
/cpuspeed.sh
Add to clientlaunch.cfg:
[cpuspeed]
ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
CMD $HOBBITCLIENTHOME/ext/cpuspeed.sh
INTERVAL 5m
SERVER:
Add the following lines to hobbitgraph.cfg:
[cpuspeed]
TITLE CPU Speed
YAXIS Mhz
DEF:speed=cpuspeed.rrd:Mhz:AVERAGE
LINE2:speed#000000:AVERAGE
GPRINT:speed:LAST: \: %5.1lf (cur)
GPRINT:speed:MAX: \: %5.1lf (max)
GPRINT:speed:MIN: \: %5.1lf (min)
GPRINT:speed:AVERAGE: \: %5.1lf (avg)\n
Modify/Add hobbitserver.cfg:
TEST2RRD: Add cpuspeed=ncv
Add line: NCV_cpuspeed="Mhz:GAUGE"
Optional: Add cpuspeed to line GRAPHS
The cpuspeed.sh could easily be extended to get values per CPU, but I
have not seen CPUs changing their speeds independently so far.

Those who don't understand UNIX are condemned to reinvent it, poorly.
