Presets Time in Cacti 1.2.28 Not Automatically Updating?

[haflinger]

Hi All!

I'm currently using Cacti version 1.2.28 and have noticed something odd regarding the "Presets time" behavior. I expected that when I select a preset time (like "Last 24 hours"), it should display the most recent 24-hour period from the current moment when the page is viewed or refreshed. However, I’ve noticed that the time is only updated at login. After, say, 20 minutes of being logged in, the preset time doesn't refresh to show the most recent 24 hours. I have to log out and back in to get the correct time range again.

Is this expected behavior, or could it be a bug in the software? Has anyone else experienced this? Any advice on how to get the preset time to refresh automatically?

By the way, big thanks to the developers for all their hard work on Cacti! It's a fantastic tool that I’ve been using for a while now, and I really appreciate all the improvements and new features in each release.

Thanks for any insights!

cannot reproduce it. Could you try another browser?
Try to clear browser cache too

[haflinger]

Thanks for your suggestion!

I tried using both Edge and Firefox, but I encountered the same issue in both browsers. Clearing the browser cache didn't resolve the problem either.

One thing I can mention, just in case it's relevant, is that I had previously configured my timezone in the config.php file with the following line:

Code: Select all

date_default_timezone_set('Europe/Warsaw'); // Time-Zone settings

I added this setting back when I was using an older version of Cacti. I'm not sure if it has anything to do with the issue, but I thought it might be worth mentioning.

Any other ideas on what could be causing this?

Thanks again for your help!

Quick update:

I noticed that in the user settings, the auto-refresh interval is set to 5 minutes, and the page does refresh after 5 minutes as expected. However, the time range still remains unchanged (it continues to show the last 24 hours from the time I logged in). The time filter in the graph view doesn't update automatically to reflect the most recent 24-hour period.

Any thoughts on why this might be happening?

Thanks again for your support!

I'm experiencing this as well. I've tried different browsers (FF/Chrome) with the same experience. The graphs load correctly upon login, but then will not refresh. Closing the browser sometimes works, but it's really only resolved by logging out and back into the Cacti UI.

[KevinNoall]

I just confirmed that clearing the cache does not do the trick (in FF at least)
Cleared cache, hit the 'Go' button in Cacti, no change.
Hit refresh the whole page, no change.
Closed the browser and reloaded, no change.
Logged out of Cacti and back in, data refreshed.

Update:
While upgrading another instance of Cacti from version 1.2.27 to 1.2.28, I encountered the same problem where the time in the “Presets” setting does not update correctly when refreshing the page.
What can I check or do?
Thanks in advance for any ideas

[haflinger]

Update: I did test. I have installed version 1.2.27 and and 1.2.28 (fresh installation).
On version 1.2.27 presets time behavior is correct and on the latest version it is wrong - as I described in the thread.

[macan]

any errors or warning in browser developer tools -> console?

[skyjou]

It seems the read_config_option function cannot get a correct value.

I change line 195 in timespan_settings.php from:

Code: Select all

$time = read_config_option('poller_lastrun_1');

to:

Code: Select all

$time = time();

It works again.

[haflinger]

I can confirm that this modification fixed it and now it works properly. Thanks!

[KevinNoall]

This change did work for me as well

[macan]

It was fixed here
https://github.com/Cacti/cacti/commit/8 ... 781dcd89b5

Update to actual 1.2.x branch

[haflinger]

I would like to confirm that the proposed change in line 195 has resolved the issue across all my installations.
Thank you for your support.
