cacti not displaying graphs

[crycos]

I have installed cacti using yum on a brand new Fedora box using this tutorial : http://docs.cacti.net/node/3 . Cacti runs fine , but it dosen't display any graphs.

Is there something I'm missing ?

I understand that I need to create the graphs for my devices. However the localhost comes preconfigured with the cacti standard installation. , but I can't see any graphs

Am I missing something ?

Hey there, i am currently trying to get cacti to display graphs too. I know what my problem is. I installed it on a debian sarge linux machine, and i got the information about my problem from /var/log/cacti/cacti.log. Perhaps you can look in there and post the messages to see if we can help you out.

I will also be opening a new thread for my current problem, so, if anybody helps me out, maybe you will be indirectly helped too.

Good luck man.

Everything seems fine in this log file

After playing with it for a while I got it to show graps, but only for the locahost, and they are empty . There is no info received from the snmp agent.

I start to hate this SNMP )


Can I get a link of your new thread

I was going thru the cacti manual and I realized that we need to run :
shell> php poller.php

Note that you must be in the cacti directory to do that.


Now I can see the graphs , but it dosen't load up any data. From the manual I understand again that the rra/ folder might be with root restrictions, so I've changed the ownership of rra/ and log/ folder to the cactiuser group and user

shell>chmod -R cactiuser.cactiuser rra/ log/

Still i'm unable to see any data flowing thru the graph .

You'll have to set up crontab to issue the poller.php command every 5 Minutes as described in the installation manual

The probllem was at the rra/ and log/ folder. It looks like I had the wrong permision., since i run "php poller.php " under root user

The folders owner must be cacti

shel>chmod -R cacti.cacti rra/ log/


Everything works fine now:

Hey, glad to know you fixed it.

I got a question for you. That line that you have specied as chmod -R ... and so on, isn't that supposed to be chown -R?

I try to change the owner of rra/ and log/ in /var/www/site/, but when typing ls -al rra/, i still get root as the owner, it doesn't change it to cactiuser. Here's the line i am typing to get this done:
chown -R cactiuser rra/ log/

The shell takes it, but it doesn't change the owner. Why is this happening?

Another thing. I got a rra symbolic link in /var/www/site that point to rra -> /var/lib/cacti/rra. This link i owned by root and chown does not change the ownership to cactiuser. On the other hand, i got the actual rra directory in /var/lib/cacti, and this directory does have cactiuser and www-data when typing ls -al rra. Could this be the problem? I think it's really weird to have it this way, so perhaps i will just remove the sym link and copy the folder over, see what happens.

I also changed user to cactiuser and tried 'php poller.php' and i get the following error:

Code: Select all

Warning: main(/etc/cacti/debian.php): failed to open stream: Permission denied in /usr/share/cacti/site/include/config.php on line 30

Fatal error: main(): Failed opening required '/etc/cacti/debian.php' (include_path='.:/usr/share/php:/usr/share/pear') in /usr/share/cacti/site/include/config.php on line 30

How can you even run poller.php as cacti if it's necessary to be root to use include/ files?

I think the install manual provided no clues.
