> > I am not sure if it appropriate to introduce more metrics about the apis.
>
> I thought we may easily recognize retrying cases by comparing two api
metrics, whether apis succeeds or not. This approach doesn't break anything. It
gives us more accurate metrics, and users can pick metrics which they want to
collect, if they don't want both.
On a long running metastore instance, the two different metrics may be
almost the same, it may bring some ambiguities and memory pressure. Just my
thought, Thank you!

> We can see that a metastore api count increments twice for one RPC, because a
> metastore server makes two timers with same name for one RPC. one for a
> retrying proxy handler and another for a hms handler. It will make api
> metrics more inaccurate, especially during retrying.
> I think new metrics for retrying proxy will be helpful to make each metric
> accurate.
