From eefa3f83f5a03a92756bcb8002270a08d684a4d1 Mon Sep 17 00:00:00 2001 From: Alexander Chadin Date: Thu, 1 Mar 2018 23:08:39 +0000 Subject: [PATCH] Tempest Fix This patch set adds gnocchi client to create resources and measures for auditing. Although we use ceilometer to get statistic, ceilometer-compute and ceilometer-central don't have enough time to dispatch metrics to gnocchi. It also adds some fixes to non-scenario tests.
