well, because my intention was to measure the actual event processor duration, excluding whatever wait time it spends on the pool. The pool wait time is statistically unrelated to the event…
not sure why not to just inline this expression, if it has only one production.
If by "ahh" you mean "I don't like this empty line", I removed it. I wish gofmt would eventually have a say on empty lines, to avoid wasting time discussing them.
I moved it to clearly split the embedded fields from the others, including this one.
You mean that should we just use a single HistogramVec for operations in general? (with a success label). Since it includes a count of the observations as well.
I didn't fully understand what you meant by "In fact, there is an operation that ended with an error or without an error."?
