cacti first install, no rra/ files and no graphs

[capitano]

Hi all I am installing cacti on openbsd 3.6.
I've create devices and graphs.
Under console/utilities/view poller cache I can see things like:
....
Data Source: cisco 827 - garagegiaco - 5 Minute CPU
RRD: /var/www/htdocs/cacti-0.8.6b/rra/cisco_827_garagegiaco_5min_cpu_12.rrd
Action: 0, OID: .1.3.6.1.4.1.9.2.1.58.0 (Host: 81.*.*.*, Community: public)
.......

in /var/www/htdocs/cacti/rra/ I've only one file called filename:
$ cat filename
[15-Nov-2004 13:25:08] PHP Notice: Undefined variable: polling_items in /var/www/htdocs/cacti-0.8.6b/cmd.php on line 97

cacti.log is empty

rra/ and log/ are chowned by the user who launch
*/5 * * * * /usr/local/bin/php /var/www/htdocs/cacti/poller.php > dev/null 2>&1

Any advice ?

thanks

Giacomo

Are you running the CGI version of PHP? If you are, make sure you make a separate php-cli version and then schedule using it. Also, change the poller to the cli version of PHP in "Settings->Paths". This should correct your problem. We must have a snippet of code that it not instructing CGI to operate in CLI mode.

To determine if you are running PHP CGI mode, run the following command:

php -v

Post your findings please.

hi

# php -v
PHP 4.3.8 (cli) (built: Nov 14 2004 03:11:01)

Sorry I didn't understand if I need php-cgi or php-cli.

Ok, goto "Settings->General" and set your logging level to DEBUG. Then disable your CRON job and open a shell window on the server. From there, run "php <webroot>/cacti/poller.php" and post your output.

First, you need to run the following from the command line and insure that they function:

perl /var/www/htdocs/cacti-0.8.6b/scripts/linux_memory.pl MemFree

perl /var/www/htdocs/cacti-0.8.6b/scripts/linux_memory.pl SwapFree

perl /var/www/htdocs/cacti-0.8.6b/scripts/unix_users.pl

perl /var/www/htdocs/cacti-0.8.6b/scripts/unix_processes.pl

Then, run poller.php in DEBUG from the command line and post your results.

I don't need localhost graphs, I need only routers graphs.

the rra/ dir continue to be empty, ther is only the file called filename, and in the in side there are those errors:

You need to change the settings in you PHP.INI file to turn OFF Save mode:
