no graph for cacti 0.8.7.d on lenny 64b

[cali]

Hi everybody.

i've just installed cacti (by apt-get) and upgrade from 0.8.7.b to 0.8.7.d in copying the files in /usr/cacti/site/ copying the content of old config file to the new and running installer.

ps: my setting is on rrdtool 1.3 and i have already test with 1.2

unfortunatly all my graphs are not. i've only there descriptions.

one thing to know is thgat i'm running debian lenny web server with DTC control panel and dtc-sbox.
the particularity is my apache user is not www-data but dtc and the group is not www-data but dtcgrp.

then i made to try to correct it:

Code: Select all

chown dtc:dtcgrp /etc/cacti/debian.php
chown -R dtc:dtcgrp /var/log/cacti/
chown -R dtc:dtcgrp /var/lib/cacti/rra

and because of the update i also made a:

Code: Select all

chmod +x /usr/share/site/cacti/poller.php

and change the cron user in /etc/cron.d/cacti
from

Code: Select all

*/5 * * * * www-data php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

to

Code: Select all

*/5 * * * * dtc php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

ps: note that the /var/log/cacti/poller-error.log file is empty

everything else should run corectly. if someone have an idea i'll read it carrefully.

I would suggest you go into graph debug and see what the errors are. Also, there are some recent patches at the Cacti Web site that are important.

ok it seem that the problem is that the rra folder is empty.
i have errors like:

ERROR: opening '/usr/share/cacti/site/rra/localhost_load_1min_5.rrd': No such file or directory

i'll search why and how to correct this issue

Edit: i didn't have (i really don't know why) the folder rra in usr/cacti/site/
very strange.
I create it and chmod777 on it. this chmod is quite large/open but ...
now i have the graph. i'll wait to know if they will be filled or not. the debug mode don't show any errors, just RRDTool Says: OK witch is quite good i think

[TheWitness]

How long does your poller run for? What does the cacti log say?

[cali]

hi, hey what i quick answer thanks a lot

then my log don't say many thing interesting (i think):

and the poller is running since yesterday. The poller error and rrd error log are empty.

and when i'm running poller by hand i have:

root@nux:/usr/share/cacti/site# php poller.php
03/07/2009 02:08:13 PM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '300' seconds, with a maximum of a '300' second Cron, but 1028 seconds have passed since the last poll!

and it add there lines in the log:

03/07/2009 02:08:13 PM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '300' seconds, with a maximum of a '300' second Cron, but 1028 seconds have passed since the last poll!

i notice that (for example) in the memory using graph it's define there files:

Code: Select all

DEF:a="/usr/share/cacti/site/rra/localhost_mem_buffers_3.rrd":mem_buffers:AVERAGE \
DEF:b="/usr/share/cacti/site/rra/localhost_mem_swap_4.rrd":mem_swap:AVERAGE \

but my rra folder is empty. And then my graphs are empty too.

[cali]

perhaps my chown is not good on /usr/cacti/site/rra folder.

when i create a new graph, and go to debug mode of this one i have a message that the rrd file does'nt exist in the folder.
witch is wrong, but the chown value of the new files are not the same:

-rw-r--r-- 1 dtc dtcgrp 47992 mar 7 14:50 new_graph_files_created_mem_buffers_10.rrd
-rw-r--r-- 1 dtc dtcgrp 47992 mar 7 14:50 new_graph_files_created_mem_swap_11.rrd
-rw-r--r-- 1 root root 141640 mar 7 14:48 localhost_load_1min_5.rrd
-rw-r--r-- 1 root root 47992 mar 7 14:36 localhost_mem_buffers_3.rrd
-rw-r--r-- 1 root root 47992 mar 7 14:36 localhost_mem_swap_4.rrd
-rw-r--r-- 1 root root 47992 mar 7 14:36 localhost_proc_7.rrd
-rw-r--r-- 1 root root 47992 mar 7 14:36 localhost_users_6.rrd

and the debug mod says:

RRDTool Says:
ERROR: opening '/usr/share/cacti/site/rra/new_graph_files_created_mem_buffers_10.rrd': No such file or directory

[TheWitness]

Your cron is not working. Please seek out the install guide for more assistance.

TheWitness

[cali]

ok i have replace by root the user in the cron and all is ok my graphs are coming.

now i'm looking to know why some templates are working and why others don't create the rrd file in /usr/share/cacti/site/rra/ folder.

[cali]

then everything is working well except when i would add a new graph.
the .rrd file is not created.

and my cacti log only have lines like:

other logs are completly empty.

if someone have an idea i'll read it carrefully

here is what i have when i test with debug option:

[TheWitness]

Looks good to me.

[cali]

Hi Witness yes it look good for the cron and task executed, but when i want to create new graphs cacti do not create the rrd files in the rra folder.

for exemple if i create new graphs with regular template as the one created by default it's work.
but if i would use other template like my one, the ones of tools plugins or any other it do not work.
the rrd file are not created.

to know: it's a rpm based cacti version for lenny upgraded to the last release and patched with the official patch.

if you need any informations don't hesitate to ask.

i have search on the forums, google, and cactiusers forums and don't find any solution

[TheWitness]

Again, this is all about permissions. If you force the poller manually as root, you may get the RRDfiles created. This is how you will know, when that problem goes away.

TheWitness

[cali]

i think so that's a permission isue, but my poller is already running as root in the cron:

Code: Select all

*/5 * * * * root php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

i try to run it as roon in the shell like:

Code: Select all

php -q /usr/share/cacti/site/poller.php --force --debug

and

Code: Select all

cd /usr/share/cacti/site && php poller.php

there is no error, but no rrd file created for all new graphs and templates.

it's very strange and i don't know as well cacti to know where to search/look to found how to resolve this issue.

[TheWitness]

Goto the poller cache and make sure the entries are there. Then edit the Data Source, turn on debug, and past that inside your shell, post any error messages.

TheWitness

[cali]

i went to the poller cache and the new graphs def are not here.
