Hi

I have the following error when I try to create a Graph
RRDTool Command:

/usr/local/rrdtool/bin/rrdtool graph - \

RRDTool Says:

ERROR: opening '/var/www/html/cacti/rra/router_tenancingo_traffic_in_42.rrd': No such file or directory

I saw the instructions in a past post and I follow it. I check the rra permission and the owner is my cacti user and it has the permission ok

I detect some particular think. Whe I run the following command inside the cacti directory

shell>php poller.php
the rrd file of my divices are created and the box of the graphic apears in the graph manager but I don't have any data.

If I set up a new device I get the error of the top.

Some one can help me with this issue , please???

Thank you

Today, I just find what's problem..
Actually, you should reconfigure connection between php and mysql

Example: dpkg-reconfigure php4-mysql
you should choose YES,in every question. And then,try it again

Thx

Thank you for the comments

I found that my problem was the PHP PATH in the crontab file, I only copy the script of the Manual but I havce another PATH in my computer to the PHP file.

This resolve my problem and now I can see my traffic graphics.

I hope this help someone.

Thank you
