@hongkailiu how can we get the jb and gojsontoyaml in go.mod correctly?

I would exclude the commit "These files got updated with make install".

@cjwagner @hongkailiu PTAL

One weirdness is what happens when we have data for a configmap from multiple hook replicas ... I can't find a "newest" aggregation operator, could use max or average i guess and get a reasonable approximation, WDYT?

I think we should figure out why the newest data are not available.
I would start with our own production (i did saw the same thing yesterday there) and check if prometheus give the right answer. I would give us an idea that it is prometheus or grafana to blame. :)
