Hi Julius,
Let me explain my use case.
For notices that alert-manger sent by receivers, I'm going to write a
webhook to store them and show them on a website.
Let's say notice-A got sent by a mail-receiver and a wechat-receiver to a
user. What I wanna do is to enable the user to be able to click a link
within the notice-A, to navigate it on the website.
Apparently every notice should have an ID that is generated by the
Prometheus, which evaluate the Alert Expression and send alerts to
alert-manager.
After going through all documents I have, still no luck to find such a
function to generate a GUID for me.
