Data collector issue.

[jantao]

Hi all!
Fresh install: Ubuntu 18.04 + Cacti 1.2.10.

I have an issue that all of my graphs stops drawing when i try to change any parameter of the Main Poller via web interface and click save.
I found that "Last Finished" and "Last update time" shifts +1hr after these Main Poller changes. Cacti log at the same moment shows valid time:

Code: Select all

04/06/2020 10:40:03 - SYSTEM STATS: Time:1.2879 Method:cmd.php Processes:10 Threads:0 Hosts:1 HostsPerProcess:1 DataSources:5 RRDsProcessed:5

My timezone is "Europe/Moscow" within php.ini. Not figured out with that issue yet, think it may be somehow DST related issue.
Any help greatly appreciated.

look in your php.ini file and make sure the timezone is right

Also, update to 1.2.11. It was just released.

Thank for your reply.

Made an upgrade to 1.2.11.
Checked timezone settings:

Code: Select all

root@cacti:~# timedatectl
                      Local time: Tue 2020-04-07 10:12:21 MSK
                  Universal time: Tue 2020-04-07 07:12:21 UTC
                        RTC time: Tue 2020-04-07 07:12:22
                       Time zone: Europe/Moscow (MSK, +0300)
       System clock synchronized: yes
systemd-timesyncd.service active: yes
                 RTC in local TZ: no

root@cacti:~# cat /etc/php/7.2/apache2/php.ini | grep date.timezone
; http://php.net/date.timezone
date.timezone = "Europe/Moscow"

root@cacti:~# cat /etc/php/7.2/cli/php.ini | grep date.timezone
; http://php.net/date.timezone
date.timezone = "Europe/Moscow"

Still Data Collector shows an hour forward than actual time in WebUI.

When you edit the collector, is the timezone set properly?

[jantao]

All worked fine BEFORE i edited collector. Timezone was correct and didn't change since initial install.

I think this might be a bug. Can you log it as such?

[jantao]

Just made fresh cacti 1.2.11 install on Centos 8.1 - same issue. I'll try to debug this and give a clue..

Console > Data Collection > Data Collectors (edit) -> Set the Time Zone.

I have right setting here (Europe/Moscow). Poller uses UTC+4 somehow, while should use UTC+3. It used to be UTC+4 in Moscow during summer season before 2014. Now it is UTC+3 all the time after 2014.

You might have to reload your Timezones into MySQL or into your OS. Governments change timezone stuff all the time, making every programmer hate life except those using MySQL (and who keep things up-to-date).
