From 725ce9dfa32f2beb1f44dc21841bceed0bc10e13 Mon Sep 17 00:00:00 2001 From: Boris Pavlovic Date: Mon, 18 Aug 2014 14:59:05 +0400 Subject: [PATCH] Improve Glance profiling Put osprofiler middleware as a almost first middleware. This allows us to: 1) Get more preciese duration. We are measuring duration of all middlewares. 2) authenticate middleware is requesting keystone, so if we init osprofiler before this middleware, we will get trace infomration from keystone as well.
