Cacti doesn't display graphs

[gardar]

Just installed Cacti yesterday, followed this manual on how to install it:
http://www.ubuntugeek.com/networkserver ... erver.html

I have version 0.8.7d of cacti and rrdtool 1.2.30.

I was able to install everything successfully, but when I'm in Cacti I don't see any graphs.... What could be wrong? How can I diagnose the problem?

Thanks

This is how it appears...

How can I debug cacti?

thats not even a nan, thats just no graph, which usually means, the rrd file wasn't created, or something is wrong with the graph template.


can you go under graph management, select a graph, and turn on debug, and paste the info?

[cigamit]

Yes, it means the RRD was not created. But most of the steps in the NaN documentation also help with figuring out why the graphs are not being created. Until we actually get some useful information so we could diagnose the issue (like his cacti.log) then all we can do is point him to documentation so he can try and debug the issue himself.

If its a fresh install (as he states) then usually it is not a Template issue, unless he was mucking about in places he shouldn't. The Graph Debug won't usually tell you anything useful either. He needs to check the permissions on the rra folder, and to check his cacti log for errors. Both of which are explained in the doc provided.

The cacti log only gives me a list of admin logins

03/06/2009 01:55:02 AM - AUTH LOGIN: User 'admin' Authenticated
03/08/2009 01:23:00 AM - AUTH LOGIN: User 'admin' Authenticated
03/09/2009 06:56:55 PM - AUTH LOGIN: User 'admin' Authenticated

etc.

I turned on debug in the graph management and got this:

ERROR: opening '/var/www/cacti/rra/localhost_5min_cpu_11.rrd': No such file or directory

What could be causing this?

[fragbait]

Same problem I think as you....

Here is what I did HERE

[cigamit]

If you are only getting the admin logins, then mostly likely your cron job is not properly running. Double check that first. You should be getting some poller stats in there.

[gardar]

That seems to be correct, I looked at my crontab and it didn't include a job for the proller.

I added this to my crontab

Code: Select all

*/5 * * * * cactiuser php /var/www/cacti/poller.php > /dev/null 2>&1

But it didn't seem to change anything, so I ran it manually.

Code: Select all

sudo php /var/www/cacti/poller.php

That gave me empty graphs, so I see I'm getting somewhere...

Now my log is like this:

Code: Select all

When running manually, add "--force" to overcome the 300 sec checks. Make sure crond is running and have a look at the /var/log/cron* output
