Hi @KevinRathgeber1,
It is highly encouraged to take time to customize the alert threshold rules to meet the needs of your organization. The defaults are by no means a "one size fits all" solution.
You can edit metrics individually by navigating to the component overview page and clicking "Edit alert rules" for the metric you want to edit:
...or in bulk via the Metrics table:
If you would like to set default alert threshold rules for metrics, you can do so in Administration > Metrics, which can then be applied to existing metrics in bulk using the "Apply rules to all instances" option:
With any of these options, you will be presented with the menu pictured below where you can customize the values for opening alerts:
Please let me know if there is anything I can clarify.
