So I recently upgraded my libreNMS host in OS version, and in turn PHP 8.2 → 8.4, so naturally I had to migrate php.ini/related settings over. In that process I forgot about timezones, and my stats got skewed for a bunch of hours until things “caught up”. That was a few days ago.
To put it more clearly, polling didn’t actually “happen” until the actual time caught up with the last time my devices were polled (when the timezone was not correctly set), as the system observed “I must be in the past, last polled info is before $now”.
Once that caught up, I was getting stats again, yay! That was a fistful of days ago.
However on my dashboard the “Recent Alerts” widget perpetually is “Loading…” and doesn’t actually finish. I suspect this is somehow related and I’m not sure what to do about it. My daily.sh is working reliably and stuff like that, so any advice would be appreciated.
