PHP Error with THOLD Cacti Plugin

[msfraticelli]

I've installed the new Cacti 1.2.30 version on a Debian 6.1.135-1 server. The php version installed is 8.2.28. The THOLD plugin installed is the 1.8.2. These packages were downloaded from the latest Github available versions.

I'm observing the threshold plugin gets disabled sporadically. According to the logs, the errors are the following:

2025-06-25 07:18:22 - CMDPHP ERROR: debounce key was truncated from debounce_page_error_thold_graph.php?headercontent=true to debounce_page_error_thold_graph.php?headercontent= Backtrace: (/help.php[43]:debounce_run_notification(), /lib/functions.php[7442]:cacti_debug_backtrace())

Any idea what can cause the errors or why the cacti application disables the plugin?

Thank you,

Please use fixed version from https://github.com/Cacti/plugin_thold/ (develop branch)

Good morning, I believe that is the same version I downloaded a few months ago. Was there a recent change to the same version?

Thank you for your response.

[msfraticelli]

Someone told there's a more stable php version than the 8.2.28 version I have installed. Can this be the case?

[xmacan]

Version is the same but in develop branch are fixes for your problem. Download it and replace files

@xmacan, is it time for a release?

[xmacan]

I don't know about any problems with actual develop.

[msfraticelli]

Thank you for your support. I've downloaded the develop version and replaced the files. I'll monitor the progress.

[msfraticelli]

Good morning, after installing the develop branch version I did notice a more stable behavior but still every 2 or 3 days the plugin gets disabled. Now the problem I have is that I don't see any error messages in the cacti log.

If there's any idea that can help resolve this issue, I'd appreciate some insight.

Thank you.

Search for "DISABLING" in your Cacti logs. When you find the file that includes it, open the file and there will be a ERROR and backtrace just before the DISABLING term. Post that here.

I had to retrieve the information several days back with the backup files.

Thanks for your reply.

Are you running this on top of Cacti 1.3?
