Hi, just to report my issue I had, maybe could be useful to others.
I saw that the "Health" section (graphics) were not working anymore, so I suspected some packages were corrupted. After an health audit (Firmware, status, audit) I found:
Error 2 occurred. etc/sysctl.conf:
(I have installed Zenarmor plugin)
Then I found this https://www.reddit.com/r/opnsense/comments/tpi1yk/health_check_error_after_installing_and/ (https://www.reddit.com/r/opnsense/comments/tpi1yk/health_check_error_after_installing_and/) , and after reinstalling the base package, reboot system, health audit was good, also graphics in Health section are working good now.
I had this issue after upgrading to 24.7_9 as well. However I have never used Zenarmor. I ran the Health Audit and everything came back clean, no errors, so I don't think I am running into this specific issue. At this point every graphic that I see in the Health Check is missing data. This feels like a bug. Can someone confirm or let me know how to fix? Here is a screenshot of what I am seeing.
Looks similar for me on apu2. Lots of holes in the data. For all metrics. As if the gathering process pauses or something.
