Unable to view graphs

[spaceman81]

Hi all,

I'm new to Linux and this is my first time setting up cacti. I managed to setup cacti but when I add a device and try to view the graph, below is what I get (in debugging mode). Help pls...

----------------------------------------------------------------------------------
RRDTool Command:

/usr/local/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="WW1-Sw1 - Traffic - Fa0/3" \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bits per second" \
--slope-mode \
DEF:a="/usr/local/cacti/rra/ww1sw1_traffic_in_130.rrd":traffic_in:AVERAGE \
DEF:b="/usr/local/cacti/rra/ww1sw1_traffic_in_130.rrd":traffic_out:AVERAGE \
CDEF:cdefa=a,8,* \
CDEF:cdeff=b,8,* \
AREA:cdefa#00CF00:"Inbound" \
GPRINT:cdefa:LAST:" Current\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdefa:MAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total In\: 0 bytes\n" \
LINE1:cdeff#002A97:"Outbound" \
GPRINT:cdeff:LAST:"Current\:%8.2lf %s" \
GPRINT:cdeff:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:cdeff:MAX:"Maximum\:%8.2lf %s" \
COMMENT:"Total Out\: 0 bytes"
RRDTool Says:

ERROR: opening '/usr/local/cacti/rra/ww1sw1_traffic_in_130.rrd': No such file or directory

Hello!!!
How many time did you wait until posting? because this kind of error is manly due to the fact that the file is created after a first poller, and the first values for this graph are collected to the second one.

The other thing who should look at is the access right one the rra files in cacti. If the user who is set up for the poller didn't have the right to modify or access to the file.

Check this two things and have a look there : http://docs.cacti.net/node/74

Hi. It has been like that for several hours now. I am not very good in linux so I am not quite clear on the instructions in the link you posted earlier. Could you kindly be more specific as to how I may check to see if the correct permissions have already been given to the poller. Thanks.
