Description of my issue

Since the update of monitorix to the latest version (3.15.0~ynh6) on two YH servers, I have the following error in the monitorix process logs :

mai 04 17:50:07 monitorix[554589]: Sat May  4 17:50:06 2024 - WARNING: inconsitency between '<graph_enable>' and 'graph_name' options; 'redis' doesn't exist.

Do you have any idea on how to fix them ?

Hello,

Thanks for the feedback.

Small question, do you have mysql/mariadb installed and enabled ?

Hi !

Thank you very much for your answer.

I guess so. I don’t know how to check it. On one server I have homeassistant installed & on the other I have OnlyOffice, Nextcloud, OpenSondage, Jirafeau & Pastebin.

For me mysql should be correctly installed because before the monitorix upgrade, all the graphs were displaying correctly. See image bellow :

Hello,

Testing by Josue-T · Pull Request #59 · YunoHost-Apps/monitorix_ynh · GitHub should partially fix your issue.

For the issue with redis I can’t reproduce your issue so I don’t really understand what is happening on your side. Did you customize your config with a file into /etc/monitorix/conf.d/ ?

Thank you for your message and the time spent.

In fact issue with redis was coming from a custom config. I was able to fix it by copying the new problematic conf part from monitorix.conf file.

I will keep you informed if you merge request fix the mysql issue on my side when it will reach the main branch.

Thank you very much for you work @Josue !

Unfortunately, upgrading monitorix from 3.15.0~ynh6 to 3.15.0~ynh7 doesn’t solve issues with MySQL connections.

I still have this error message in the log
