[cosminb29]

Hello

RRDTool Command:

/usr/local/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="cosmin internet - Traffic" \
--rigid \

RRDTool Says:

ERROR: opening '/usr/local/www/data-dist/cacti/rra/cosmin_internet_traffic_in_50.rrd': No such file or directory


and also rrdtool is installed but wont create the rrd file any ideea how to resolve it?

Lots of possible causes
- wrong permissions. Not likely to be the cause, if other rrd files were created successfully
- host status is not "up". Indicates, that an availabilty test fails
- not waited for the poller to run at least twice after graph generation. The poller will create those files
- perhaps more
See my link on "NaN Debugging". It does not match exactly, but includes some general hints and tips that may show the root cause
