new/imported graphs not showing

[filco]

Hello Cacti forum,

This issue seems to be rather persistent in this forum, but no tip or trick has helped me yet. I've been using Linux for less than a week and my boss just made me the Cacti SME. FAQs and Debugging has not helped. I have a Windows server admin background and I don't know how to diagnose Linux problems. I've been instructed to setup my own Cacti server to play around with before I am given admin rights to our production servers, which also run Linux. Today is the third day i've been trying to diagnose this Cacti issue.

I've setup Cacti in a VM running Ubuntu 10.10. Everything seems to be working great, but any new graphs that I either add or import do not display. the standard 4 rrd files are located in the rra folder but new rrd files are not generated. the rra folder has been given 777 permissions (i don't think this would be appropriate for production). between the .ini / crontab / cron.d whatever files, I have no idea where permissions are supposed to be set. I am just presuming that this is a permissions issue.

I'm really looking forward to this career change and working with Cacti permanently, but this has a rather large learning curve. But I learn best by trial and error, so if you're willing to help me through whatever steps, i'd really appreciate it.

Nothing seems to indicate mis-management of newly created rrd files.
Does anything look off?

Yes, I've read it. And even tried executing what I could figure out. But your infamous 2nd link of your sig is not a cure-all. I read the book, too, and it raves about how great of a support forum this is. The book also raves about how easy Cacti is to use. So what do I do if the senior members of this forum point me to a howto that i've already read? How about you re-write it for people that might not know what they're doing, which are probably the majority of the people that use it? I've crawled this forum for this problem and there is nothing that helps.

I surely will do so.
But please accept my apologies that after working 4 years on this topic, I might have some problem understanding the real issues behind those problems. And pointing me to my lack of seeing through your eyes does not help me, indeed. From your words above, I was not able to deduce that you've read my docs; unfortunately, many users do not (sigh).
But, looking forward, we may simply start by rephrasing your question. It might even help telling us which steps you were able to execute and which results you did achieve. For me, it's quite hard to guess which of those steps were not explained well enough.
I often make the offering to adopt any hints enhancing the documentation in case you provide a better wording. In fact, this is a dokuwiki, so you can do so without me.

Concentrating on a single issue from your log file (this will perhaps not cure all problems), let's tackle

Result "U" means, that there was no valid numeric result when running the given command.

Then, run "php -q rebuild_poller_cache.php". More possible issues are, that the user running the poller (e.g. "cactiuser" has insufficient access to "ping.pl" or to commands used therein.
One of the generic issues for rrd files not being created is that the user running the poller has not enough permissions to write to the <path_cacti>/rra foled (whatever this resolves to on your ubuntu system)
R.

[filco]

Thank you for that information. On top of tackling Cacti, my boss is having me write perl scripts using regex and subroutines. It's quite the load for someone brand new to *nix. Anyways...

It seems as though Ubuntu 10.10 uses the www-data user for cacti related functions. When I was setting up cacti, i was literally using "cactiuser" as my user, but i've since modified permissions to use www-data. i've also added:

*/1 * * * * root /usr/bin/php -q /var/www/cacti/poller.php > /var/log/poller.log 2>&1

to my /etc/crontab

for some reason my poller stopped running altogether, then i added that line into crontab.

But now i'm back to my original problem... the built in templates are not getting displayed.
this is my output from: /var/log/cacti/cacti.log:

It is NOT recommended to use rott to run the poller. "cactiuser", or, in your case "www-data" should do. Please take care of permissions of rrd files that have been created by root already!

this is my output from: /var/log/cacti/cacti.log:

This makes me think, that there are two pollers running in parallel. One every 60 sec. and one (the default) every 5 minutes. The last one seems to succed, as he finds data that should be polled.
Please know, that my personal opinion is to not support 1 min polling (it sucks with current cacti, never use it until you consider yourself being an experienced user).
So please see 2nd link of my sig (yes, again) and TRY to find BOTH crontab entries that SEEM to be in effect.

Of course, my assumption may fail

Am I supposed to have setup SNMP (snmp, snmpd or net-snmp)? I ask because i've been trying to setup an SNMP v3 user. There are no guides on the Internet that make sense how to do this. Currently my local device, and the other local test devices are using ping.

Thank you for your continued support. I have not been able to find any evidence for a second cronjob. The only one I can find is in /etc/crontab. Are there any other rocks I should be looking under?
