This patch added the support of unavailable metrics in the metric weigher. Based on the configuration, if an unavailable metric is met, the metric weigher might either throw an exception, or return an configurable weight value. This is part of the blueprint utilization-aware-scheduling. DocImpact: Added support of unavailable metrics. 2 new config options are added, 1) 'required' is a boolean option indicating whether all the metrics set by 'weight_setting' are needed to be available when calculating the weight. 2) 'weight_of_unavailable' is a float option specifying the value to be returned if the metrics is unavailable. See etc/nova/nova.conf.sample for details. Change-Id: Icb951605aae28487b00a12d172a3ac4dafda2cdb |
