Hello, If running the scripts manually the graphs are created successfully then the problem is in your crond daemon, not in Monitorix. Don't show me the contents of these two files after executing the scripts manually since we already know that it works this way. Please, remove these files and let your crond create them, and then read their contents and see if are correct. Besides this, I see some errors in your log file that makes me think that your configuration file is either outdated or you removed a lot of lines from it, which is not recommended. Please, read the FAQ <https://www.monitorix.org/faq.html#Q107> to know how to configure Monitorix properly. Regards.
