Have you at least run the poller one time?

The rrd files that are used to graph are created/updated by the poller. If the poller hasn't run, then no graphs.

[ramax]

thanks for your reply

i run the poller.php manualy ( not on root )

i type in cacti directory : php poller.php ( i see this in manual of cacti )

the graph is not broken now but empty ...

i continous to follow the manualy with my bad english lol but i afraid to make an bad error

[ramax]

i have file in RRA directory and your manual say to type : ls -al rra/

same probleme , gfx is empty

i run the graph debug mode in graph management , gfx is already empty


do you have an idea ?

Are you running the poller every 5 minutes from cron/scheduler? This important, as you will not see data in the graphs until at least to polls in a row. That is the way RRDtool works.

yes i think, i edit the etc/crontab file

Code: Select all

[cacti@ns1 etc]$ cat crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

*/5 * * * * cacti_db php /home/cacti/domains/cacti.cledunet.com/public_html/cacti/poller.php > /dev/null 2>&1

[cacti@ns1 etc]$

do you see an error ?

[rony]

Yep, problem.... Is php in the path defined in the crontab? I would suggest that you put the full path to php in cron.

Also, you can confirm this by checking the cron logs.

i modify /etc/crontab with the complet URL for php

Code: Select all

[root@ns1 etc]# cat crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

*/5 * * * * cacti_db /usr/local/bin/php /home/cacti/domains/cacti.cledunet.com/public_html/cacti/poller.php > /dev/null 2>&1

graph is empty

and when i type php poller.php i have some error :

Ton utilisateur qui execute le script 'pooler.php' ne devrait il pas être plutot le user de Apache. Je serais etonné que ton user Apache soit 'cacti_db'. En fait l'utilisateur qui execute le script, pour toi cacti_db, doit avoir les droits d'ecriture dans les repertoires 'cacti/log' & 'cacti/rra' sans cela ca ne fonctionnera jamais.

Translation ala google:

Your user who execute script ' pooler.php' should not it not be rather to use it of Apache. I would be astonished that your to use Apache is ' cacti_db '. In fact the user who execute script, for you cacti_db, must have the rights of writing in the repertoires ' cacti/log' & ' cacti/rra' without that Ca will never function.

Good point.
