I have set up LibreNMS from scratch and am beginning to modify some alert rules and templates. However, when I try to detach alert rules from the default alert template to attach them to a newly created one, I cannot see any attached alert rules in the edit window, even though they are still displayed on the informational screen.
- You can refer to the two attached images for a better understanding of my current situation. I would greatly appreciate any assistance or guidance you can provide.
- Here is my validate.php output:
