I come to see no graphs

[ingenious]

Hello,

I've installed Cacti 0.8.7b on a SUSE Linux 10.1 (X86-64) with 2.6.20.21-071108a kernel. Some more system information:

/usr/bin/php5 -v
PHP 5.1.2 with Suhosin-Patch 0.9.6 (cli) (built: Dec 12 2007 02:15:51)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies

/usr/bin/rrdtool -v
RRDtool 1.2.12 Copyright 1997-2005 by Tobias Oetiker <tobi@oetiker.ch>
Compiled May 2 2006 08:52:38

In the cacti graphic interface I get [OK: FILE FOUND] for everything(except for spine of course) in settings > paths. It also displays that Devices > Localhost is up and I see the snmp information about localhost. I'va added couple of graphs I'd like to observe, but I only get e.g. Localhost - Memory Usage, and no image at all.
When I disable polling and run the poller.php mannualy I get the following:
php5 poller.php
07/30/2008 10:16:07 AM - POLLER: Poller[0] NOTE: Poller Int: '300', Cron Int: '300', Time Since Last: '364', Max Runtime '298', Poller Runs: '1'

And I'm pretty much lost. I'd appreciate any help at all

You are either jailed by your hosting company or PHP is running in safe mode. You have to resolve that.

phpinfo() says:
safe_mode Off(local) On(master)

so I guess it's not it. What do you mean "jailed" ?

[TheWitness]

Your messages indicate otherwise. Is this your own server, or are you running on a Hosting Companies hardware? If on someone else's hardware, talk to them about your problem. Let us know how it goes. If it's your own environment, your /etc/php.ini file controls PHP's behavior. Look for the words "safe". Make the appropriate changes and restart Apache.

it's a server of my own more or less... It's a server at the company I work for.

There is a /etc/php5/apache2/php.ini and it says
safe_mode = On
and that's the master value from my phpinfo() ( http://cacti.b-wise.info/phpinfo.php )
But still the safe_mode should've been disabled for the current subdomain... I'll keep poking around for a little while ... probably I'll get the people at the office to agree we should disable safe_mode globally...
anyway, thanks a lot !

I think I've fixed it:

I've added a local php.ini file with

Code: Select all

safe_mode = Off

and an .htaccess with

Code: Select all

php_flag safe_mode off

and now I get
php5 poller.php

So I guess I'll be seeing graphs in just a couple of minutes thanks for the help one more time !
