When I am started to study watcher , i see lots of keywords in watcher examples . Samples are showing below
But these keywords are I never found in watcher documentation .
From where I can study these terms meaning and its usage ?
For example I want to know what is ctx, payload and how to make this queries combinations ?
Basic intention is i want to create custom watcher for my ML jobs
Now I am using GUI for creating watcher for my ML jobs
