Graphics Issues

[sadzas]

Somebody knows why this happens?

Thanks!!



I turn on the graph debug mode...

RRDTool Command:

/usr/bin/rrdtool graph - \

--end=-300 \

RRDTool Says:

ERROR: opening '/var/www/cacti/rra/localhost_mem_buffers_3.rrd': No such file or directory

Is not a permissions issues.. but /var/www/cacti/rra/ is empty..

This is all what my log say:

Have you verified that the poller runs properly from whichever crontab it's being run from? If the rrd files don't exist, I would suspect that the poller is not running.

How I do that?

I have installed the RRDTOOL twice..

Once I did it from:
$ sudo wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.2.18.tar.gz

After that and seeing the error, I have tried:
$ sudo apt-get install rrdtool

Thanks for the quickly answer..

Which installation guide did you follow?
Are you using cmd.php or spine for your poller?

During your cacti setup, you should have created a user to run cacti under. That users crontab should contain an entry like the following:

*/5 * * * * /usr/local/bin/php /usr/local/share/cacti/poller.php > /dev/null 2>&1

Of course you would need to change the paths to match your setup.
You can look in your cacti.log to see if its being run.

I think do I follow the wrong guide...

Which guide do you recomend ?? under debian distro..

thanks

I'm not sure how up to date this guide is, but it should at least point you in the right direction.

I also have the same problem - we want to resolve

You should manually run:

Code: Select all

php -q poller.php --force

You should be looking for OK's. If the file is still not present, you should check for the name of the RRDfile in the poller cache. If it is not there, attempt to Repopulate the Poller cache. If it magically appears thereafter, I will need to know where you obtained your Cacti install from and how it was installed.

Thanks! Solved!

The secret (Just like the Asterisk) is on Installation !!

There is no secrets...
