You have been subscribed to a public bug: After release upgrading from 12.04 to 12.10, I remarked that the graphs are not updated anymore and the modify date of the files in /var/lib/cacti/rra was a timestamp before the upgrade.
I had many lines in /var/log/cacti/poller-error.log like this one: PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /usr/share/cacti/site/lib/functions.php on line 486 According to the FAQ page of cacti, I adjusted the php.ini in /etc/php5/cli and /etc/php5/apache2: http://docs.cacti.net/faq#time_zone_warning According to the PHP documentation, the behaviour in PHP 5.4 changed: http://www.php.net/manual/en/function.date-default-timezone-get.php First I thought that it is a bug of the packages php5-cli and libapache2-mod-php5 which do not set the date.timezone in their respective php.ini files. You can see that if you execute the following 2 commands: dpkg-query --control-show libapache2-mod-php5 postinst dpkg-query --control-show php5-cli postinst There is only the default php.ini from the package copied without setting the date.timezone variable or let the user choose one. But then I recognized, that the PHP script is executed to the end, also if the date.timezone variable is not set in php.ini Let me demonstrate this in 3 examples: 1) Ubuntu 11.10 with timezone Europe/Zurich in /etc/timezone, no date.timezone set in php.ini and PHP version 5.3.6-13ubuntu3.9: user@hostname1:~$ echo; lsb_release -a; echo; uname -a; echo; cat /etc/timezone; echo; grep "date\.timezone" /etc/php5/cli/php.ini; echo; php -r 'echo date_default_timezone_get()."\n"; echo phpversion()."\n"; echo date("r")."\n"; echo strtotime("now")."\n"; echo "\nall commands executed with success\n\n";' No LSB modules are available.

IMHO it has to be solved either in the cacti package or the bug should be assigned to php5-cli and libapache2-mod-php5 to let them set the date.timezone variable in the postinstall routine. package versions: user@hostname3:~$ LC_ALL=C apt-cache policy cacti cacti: Installed: 0.8.8a-3 Candidate: 0.8.8a-3 Version table: *** 0.8.8a-3 0 500 http://ch.archive.ubuntu.com/ubuntu/ quantal/universe amd64 Packages 100 /var/lib/dpkg/status user@hostname3:~$ LC_ALL=C apt-cache policy php5-cli php5-cli: Installed: 5.4.6-1ubuntu1 Candidate: 5.4.6-1ubuntu1 Version table: *** 5.4.6-1ubuntu1 0 500 http://ch.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages 100 /var/lib/dpkg/status user@hostname3:~$ LC_ALL=C apt-cache policy libapache2-mod-php5 libapache2-mod-php5: Installed: 5.4.6-1ubuntu1 Candidate: 5.4.6-1ubuntu1 Version table: *** 5.4.6-1ubuntu1 0 500 http://ch.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages 100 /var/lib/dpkg/status user@hostname3:~$ ** Affects: php5 (Ubuntu) Importance: Undecided Status: New ** Tags: quantal -- No graph updates after upgrade to 12.10 because date.timezone not set in php.ini https://bugs.launchpad.net/bugs/1069529 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in Ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
