cacti does not create rrd files automatically

[leventkurt]

Hi there,

I used cacti for two years in my old company with no problem at all. I tried to install cacti to my new company but I find my self in trouble

I googled and search forums threads but i couldn' t find my problem's solution.

Let me explain the situation a bit:

- CentOS release 4.6 (Final) is being used.
- rrdtool, mysql, apache and php are intalled from scratch.
- downloaded 0.8.7b version of cacti and installed.

When I add a device, cacti sees all its properties with no problem. I tried localhost (linux) and also a router (cisco) in our system, i've added some active devices.

The problem is that cacti is not creating any rrd files by itself.

I opened one of data source in debug mode, and see this:

Code: Select all

/install/rrdtool/rrdtool-1.3.0/bin/rrdtool create \
/install/apache/apache-2.0.63/htdocs/cacti/rra/<privateinfo>.rrd \
--step 300  \
DS:5min_cpu:GAUGE:600:0:100 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797

When I copy this line and execute, It really does create an rrd file.

First thing you would say this is a cron management problem; but it's not.

When i execute cmd.php it does not create any rrd at all; also i put cmd.php as (i know i should use */5, used everymin to see if cron works or not):

Code: Select all

* * * * * cacti /install/php/php-5.2.6/bin/php /install/apache/apache-2.0.63/htdocs/cacti/cmd.php 1> /tmp/cacti1.log 2> /tmp/cacti2.log

when i check /tmp directory:

Code: Select all

# ls -l /tmp/cacti*
-rw-r--r--  1 cacti cacti 3457 Jul  7 11:12 /tmp/cacti1.log
-rw-r--r--  1 cacti cacti    0 Jul  7 11:12 /tmp/cacti2.log

everythings seems ok, but steel no rrd.

I also used "chmod 777 * -R" and "chown cacti:apache * -R" on cacti root
directory to eliminate permission issues.

This is the output of the cmd.php:

Code: Select all

# /install/php/php-5.2.6/bin/php cmd.php

What I'm missing?

Please see 2nd link of my signature for further debugging. Your post shows, that data gathering is fine, but the HowTo may help you going on further

hi there,

i tried every solution you have one by one but didn't work. i had a look to php.ini to see if there's something wrong about variables:

register_globals = On
register_long_arrays = On
register_argc_argv = On

(I think register_globals is not the problem here, I set it to "On" to be sure.)

The problem remains as the same, I create a device (no problem), it searches for interfaces (np), I add an interface (np) but neither crontab cmd.php nor manually running of cmd.php creates relevant rrd files in rra directory.

But If I look to Data Source in Debug mode, copy/paste and run the rrdtool create ..... It really does create rrd file.

So my question is the following:

Where is the part that cacti understands that it has to create a rrd file and runs "rrdtool create ....." function? I think I can debug easily I have this information and add mine experience to your page as a solution

[gandalf]

See lib/poller.php and search for process_poller_output function

Thanks for your replies, I reconsidered every step from scratch and this time I installed as a cacti newbie. Voila, it solved

The problem is the cron line (also I'm using in command line for trials):

Code: Select all

* * * * * cacti /install/php/php-5.2.6/bin/php /install/apache/apache-2.0.63/htdocs/cacti/[b]cmd.php[/b] 1> /tmp/cacti1.log 2> /tmp/cacti2.log

If I replace cmd.php with poller.php it'ok

This poller.php reads what to use as a poller and uses spine / cmd.php from settings right?

Again thanks for your help man ..

[gandalf]

Shame on me; I did not see this in your first post. Too much work ...
Reinhard

[leventkurt]

No problem mate, I shouldn't be so self-confident and read again whole installation.

By the way, poller.php reads what to use as a poller and uses (forks) spine / cmd.php from settings and executes, right?

Thanks for all the information.

[gandalf]

Yes. And more: spine and cmd.php will store all values in poller_output table. Only poller.php will fetch data from there and update rrd files

Thank you again.
