When adding procedure to a rule, you can only add http:// links, according to this doc: http://docs.librenms.org/Extensions/Alerting/#rules-procedure I am able to add and save https links to the rule, but when I get an alert and click the procedure box, I get a notification saying "Procedure link does not seem to be valid, please check the rule"

It would be nice if the alert widget box also could support https://

Also I'm not sure how to use %placeholders in the procedure link? If it's currently not possible, this can be seen as a feature request for that aswell :-)
