Hi, I am new to cobbler and I want to use triggers use to do some post install tasks, suck as create a system profile when the system finish the first boot from cobbler . 

I have read the docs at http://cobbler.github.io/manuals/2.6.0/4/4/1_-_Triggers.html. But still do not know how to call the triggers, which url I should  send request to.

Hope somebody can provide detail docs for how triggers work, Thanks.
