excellent. now I have just started looking at rrd over the last couple of
days, maybe thinking of replacing my mrtg setup with it. there a couple of
questions for now:
first, a simple one, if I have many different objects/processess being
monitored, is it a good ides to segregate them into individual rrd files or
do you just chuck them all in together?
and now one in at the deep end: the tutorial at people.ee.ethz.ch/ gives the
following example:
rrdtool graph speed4.gif \
--start 920804400 --end 920808000 \
--vertical-label km/h \
DEF:myspeed=test.rrd:speed:AVERAGE \
"CDEF:kmh=myspeed,3600,*" \
CDEF:fast=kmh,100,GT,100,0,IF \
CDEF:over=kmh,100,GT,kmh,100,-,0,IF \
CDEF:good=kmh,100,GT,0,kmh,IF \
HRULE:100#0000FF:"Maximum alllowed" \
AREA:good#00FF00:"Good speed" \
AREA:fast#550000:"Too fast" \
STACK:over#FF0000:"Over speed"
the line I am interested in is the CDEF that calculates the 'over' variable.
I have an rrd which stores in and out traffic for eth0 on my development
machine and I graph (from a perl script) it like so:
system("rrdtool graph /var/www/html/rrdtool/eth0.gif \\
--start -43200 --vertical-label bytes/second \\
--title \"eth0 Traffic Monitor\" \\
DEF:inoctets=/var/www/html/rrdtool/eth0.rrd:input:AVERAGE
DEF:outoctets=/var/www/html/rrdtool/eth0.rrd:output:AVERAGE
HRULE:20000#0F0000:\"Limit of Sensible Load\" \\
LINE2:inoctets#00FF00:\"In traffic\" \\
LINE2:outoctets#0000FF:\"Out traffic\"");
I want to be able to do something like the CDEF and STACK from the turorial
example where if the in or outgoing eth0 traffic is above a certain
ammount, then print it in a different color like the example. I have tried
adding the line and jst changing 'kmh' for 'inoctets', but it just makes the
graph go strange. Please can someone explain how that CDEF works so I can
customise it.
Thanks guys
