From 8dcef88edb5b9883c23510be8a2ab67d9e45b576 Mon Sep 17 00:00:00 2001 From: Thomas Goirand Date: Wed, 7 Apr 2021 18:54:22 +0200 Subject: [PATCH] Add support for gnocchi_api_uwsgi_config in Debian This patch is adding the configuration of the number of workers, threads, and the size of the listen queue in Debian, which uses uwsgi to run Gnocchi API. Therefore, this patch adds a new gnocchi_api_uwsgi_config providers as well as a new gnocchi::wsgi::uwsgi_api class.
