Empty graphs in cacti 0.8.8a

Post by ute »

Hi guys.

I've got a problem with a new instalation of cacti.

S.O. Debian 7 kernel 3.2.81-1 x86_64
cacti and cacti-spine via apt-get.

The problem is that the graphs are empty with nan values.
This is a list of the things that I did:

1- chown -R www-data /var/lib/cacti/rrra
2- chmod 777 www-data /var/lib/cacti/rra
After the step 2 the graphs apear but with nan values.

crontab -e
*/5 * * * * /usr/bin/php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

but the command
php poller.php it has no output ???

This is the output of php -m

bcmath

In some moment it seems that the poller get some information cause the graphs have some valueas but then has no data.

this is the output of php cmd.php

Do you mean to say that that directory was owned and secured differently? Any idea how that happened, as the Debian package should do that by itself.

Why didn't you use the provided cron job in /etc/cron.d/cacti?

Seems like you ran cacti with your own credentials resulting in numbers and the standard polling doesn't work...

I believe there is a bug open about this.

And this looks like a failing device, script or query.

I suggest you read the debugging documentation in my signature, and come back which specific questions.

Before i have installed a cacti version for 0.88a and 0.88b and i got the same problem with you, the graph is not showing, after that i tried to downgrade with version 0.88 and the graph is showing.
i check all like poller.php out, time server etc is no problem.

I've got 2 other instalation of cacti installed on debian 7 same version, and cacti 0.88a installed via apt-get and It works perfect with no problem.
On last friday I left the cacti working when I went home there was no data in graphs but today I found this

It seems to be ok but now the time is 9:51am. I've got no data between 7:50am and 9:50am. No data in the last 2 hours in all graphs. Using the plugin realtime I can check that there is data.

Are your timezones OK in THREE places: system, php and mysql?

Thanks everybody. The problem has been resolved.
I've unistalled everything and then I've installed all.
Then I changed the permisions in /var/lib/cacti/rrr to 777 , cause RRD can't generate the graphs.

Then verything works ok.

Thanks
