Post pooler is runnig. folder permission ok. but graph is empty
I ensure my pooler is running.

Code:
tail -f /var/log/cacti/cacti.log

06/30/2009 04:00:03 AM - SYSTEM STATS: Time:2.0192 Method:cmd.php Processes:1 Threads:N/A Hosts:2 HostsPerProcess:2 DataSources:5 RRDsProcessed:0

I ensure my folders permission are OK.

Code:
yanchengclean:/tmp/cacti-0.8.7e# ls -al /var/log/cacti
total 192
drwxr-xr-x 2 cactiuser www-data   4096 Jun 30 03:48 .
drwxr-xr-x 8 root      root       4096 Jun 30 03:13 ..

-rw-r--r-- 1 cactiuser www-data  47840 Jun 30 03:20 localhost_users_6.rrd
yanchengclean:/tmp/cacti-0.8.7e#


If you compare timestamp for localhost_load_1min_5.rrd and cacti.log, localhost_load_1min_5.rrd is not being updated at all.

May I know what else I need to look into it?

Thanks!

Run your poller in medium mode, and see what result the script is returning to the Cacti log.

I turn the logging mode even to DEBUG:

Code:
cactiuser@yanchengclean:/$ php /usr/share/cacti/site/poller.php
07/01/2009 02:54:58 AM - POLLER: Poller[0] DEBUG: About to Spawn a Remote Process [CMD: /usr/bin/php, ARGS: -q /usr/share/cacti/site/cmd.php 0 1]
Waiting on 1/1 pollers.

cactiuser@yanchengclean:/$


Is the poller running correctly? Is this what the output should be?

check you cacti (from the interface or ./log/cacti.log) and see what result the script is returning. Running the poller manually is not going to show the results from cmd.php on the screen, you have to look at the log for that info.

I try your advice :

Code:

yanchengclean:/# su cactiuser


cactiuser@yanchengclean:/$ php /usr/share/cacti/site/poller.php
07/02/2009 07:18:37 AM - POLLER: Poller[0] DEBUG: About to Spawn a Remote Process [CMD: /usr/bin/php, ARGS: -q /usr/share/cacti/site/cmd.php 0 1]

cactiuser@yanchengclean:/$ php -q /usr/share/cacti/site/poller.php --force
07/02/2009 07:18:48 AM - POLLER: Poller[0] DEBUG: About to Spawn a Remote Process [CMD: /usr/bin/php, ARGS: -q /usr/share/cacti/site/cmd.php 0 1]

cactiuser@yanchengclean:/$ vi /var/log/cacti/cacti.log


When I check the log file, I get the following message :

Seem like my SNMP server is not running properly? How can I start my SNMP server?

Change it to MEDIUM instead of debug
