[GitHub] wohali opened a new issue #1116: Consider eliminating known-slow requests from request_time stats/histogram

wohali opened a new issue #1116: Consider eliminating known-slow requests from request_time stats/histogram
URL: https://github.com/apache/couchdb/issues/1116
 
 
   Ran into this with a client recently. Here's what we do right now:
   
   https://github.com/apache/couchdb/blob/master/src/chttpd/src/chttpd.erl#L353-L354
   
   But it might be nice to ignore specific types of requests that are known to run long, that will skew the histogram/averages, such as:
   
   * /_replicate
   * any DB and global changes feeds with continuous or longpoll options
   
   We could also relegate these to a separate "long request" histogram stats bucket.
