mno , nakoniec som od toho loadavg upustil a rozbehal som zopar skriptov v spolupraci s rrdtool a ide to krasne .. akurat neviem pochopit jednu vec , vyuzitie cpu mam cez load average (priemerna zataz ??) no aj ked som cpu zatazil na 30min na 100% na grafe som videl maximalne 2.0 .. co to teda znamena ?
jedna sa o tento skript :
#!/bin/sh
DATABASE_DIRECTORY="/var/www/load/rrd"
GRAPHS_DIRECTORY="/var/www/load"
create()
{
mkdir -p $DATABASE_DIRECTORY
if [ -f $DATABASE_DIRECTORY/cpu_load.rrd ];then
return
fi
/usr/bin/rrdtool create $DATABASE_DIRECTORY/cpu_load.rrd -s 300 \
DS:load1:GAUGE:600:0:U \
DS:load5:GAUGE:600:0:U \
DS:load15:GAUGE:600:0:U \
RRA:AVERAGE:0.5:1:483840 \
RRA:MIN:0.5:1440:1 \
RRA:MAX:0.5:1440:1 \
RRA:MIN:0.5:10080:1 \
RRA:MAX:0.5:10080:1 \
RRA:MIN:0.5:40320:1 \
RRA:MAX:0.5:40320:1 \
RRA:MIN:0.5:483840:1 \
RRA:MAX:0.5:483840:1
}
graph()
{
RRDB=$DATABASE_DIRECTORY/cpu_load.rrd
NOW=`date +%s`
ONE_DAY_AGO=$(($NOW-86400))
ONE_WEEK_AGO=$(($NOW-604800))
ONE_MONTH_AGO=$(($NOW-2419200))
ONE_YEAR_AGO=$(($NOW-29030400))
TIMESTAMP="Vygenerovane `date|sed 's/:/\\\\:/g'`"
draw_graphic 'cpu_load_last_day.png' $ONE_DAY_AGO $NOW "$HOSTNAME za poslednych 24 hodin" "$TIMESTAMP"
draw_graphic 'cpu_load_last_week.png' $ONE_WEEK_AGO $NOW "$HOSTNAME za posledny tyzden" "$TIMESTAMP"
draw_graphic 'cpu_load_last_month.png' $ONE_MONTH_AGO $NOW "$HOSTNAME za posledny mesiac" "$TIMESTAMP"
draw_graphic 'cpu_load_last_year.png' $ONE_YEAR_AGO $NOW "$HOSTNAME za posledny rok" "$TIMESTAMP"
}
draw_graphic()
{
rrdtool graph $GRAPHS_DIRECTORY/$1 -s $2 -e $3 -a PNG \
-t "Vytazenie procesora pre $4" \
-l 0 -r --units-exponent 0 \
-h 114 -w 500 \
-v "percent" \

COMMENT:"\n" \
COMMENT:"$5\n"
}
update()
{
rrdtool update $DATABASE_DIRECTORY/cpu_load.rrd `cat /proc/loadavg | awk '{ print "N:"$1":"$2":"$3 }'`
}
case $1 in
"create" )
create
;;
"graph" )
graph
;;
* )
update
;;
