Blank Graph

[xpreme]

Hi,
I have installed Cacti 0.8.8b on Ubuntu 14.10 x64 (in VMware Workstation 9). I have added a real (physical) PC running on windows 8 in cacti. There is no SNMP error. Everything seems to be OK. But I always get blank graphs. Here is an example:

RRDTool Command:
/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start='-86400' \
--end='-300' \
--title='Mohsen PC - Traffic - ethernet_8' \
--rigid \
--base='1000' \
--height='120' \
--width='500' \
--alt-autoscale-max \
--lower-limit='0' \
--vertical-label='bits per second' \
--slope-mode \
--font TITLE:10: \
--font AXIS:7: \
--font LEGEND:8: \
--font UNIT:7: \
DEF:a='/var/lib/cacti/rra/mohsen_pc_traffic_in_57.rrd':'traffic_in':AVERAGE \
DEF:b='/var/lib/cacti/rra/mohsen_pc_traffic_in_57.rrd':'traffic_out':AVERAGE \
CDEF:cdefa='a,8,*' \
CDEF:cdeff='b,8,*' \
AREA:cdefa#00CF00FF:'Inbound' \
GPRINT:cdefa:LAST:' Current\:%8.2lf %s' \
GPRINT:cdefa:AVERAGE:'Average\:%8.2lf %s' \
GPRINT:cdefa:MAX:'Maximum\:%8.2lf %s\n' \
COMMENT:'Total In\: 0 bytes\n' \

GPRINT:cdeff:LAST:'Current\:%8.2lf %s' \
GPRINT:cdeff:AVERAGE:'Average\:%8.2lf %s' \
GPRINT:cdeff:MAX:'Maximum\:%8.2lf %s\n' \
COMMENT:'Total Out\: 0 bytes\n'
RRDTool Says:
OK



What should I do?

Thanks in advance,

Change the logging to MEDIUM and make sure you are getting actual data back from the device.

I did what you mentioned. But it didn't work

I didnt say it would fix your issue. You need to do that, and then check the log and find the entries where it is pulling data for that host / graph. If its not pulling data, then you have somewhere to start looking / troubleshooting the issue.
