Hi,
Does ES expose the "total latency" stats - meaning, the latencies that the
user sees as "took" in responses? The only latency stats I see ES exposing
in the stats API are the latencies from requests between individual nodes,
which can often be much shorter than the total latency and thus misleading.
For example, we had a customer recently whose index was simply poorly
balanced and one of the nodes was a bottleneck. The ES stats all looked
fine, but the "took" in the response was not fine - it was much bigger,
because the response speed was controlled by the slow node, not by the
average speed of responses between individual nodes, which ES Stats API
reports, I believe.
Does ES expose the "real"/total latency?
Thanks,
Otis
