This is a question for a best known method to send metrics from virtual and bare metal instances through collectd > collectd-gnocchi plugin, to our controller node.
The cluster components are: - One controller node - Two compute nodes - Virtual machines instances - Bare metal instances We are using CentOS, OpenStack version Stein has been installed using PackStack with Telemetry service enabled, and Gnocchi as database. The related packages installed through YUM and their versions are the following: - gnocchi-api.noarch 4.3.2-1.el7 - gnocchi-common.noarch 4.3.2-1.el7 - gnocchi-doc.noarch 4.3.2-1.el7 - gnocchi-metricd.noarch 4.3.2-1.el7 - gnocchi-statsd.noarch 4.3.2-1.el7 - collectd.x86_64 5.8.1-1.el7 - python2-collectd-gnocchi.noarch 1.7.1-1.el7 And our existing Gnocchi authentication method is keystone. We are collecting data through collected > collectd-gnocchi from our controller and compute nodes without any issue, using keystone authentication method: Gnocchi Configuration [keystone_authtoken] www_authenticate_uri=http://10.10.10.6:5000/v3 auth_uri=http://10.10.10.6:5000/v3 auth_type=password auth_version=v3 auth_url=http://10.10.10.6:5000 username=gnocchi password=somepassword user_domain_name=Default project_name=services project_domain_name=Default Collectd configuration :: collectd-gnocchi plugin <Plugin python> <Module collectd_gnocchi> Auth_Mode keystone Auth_Url "http://10.10.10.6:5000"; Username admin Project_Name admin Password somepassword User_Domain_Name default Project_Domain_Name default ResourceType controller_node </Module> </Plugin> The next step is to enable the collection of data through collected plugin in virtual machines and bare metal instances but existing keystone configuration requires us to have the collectd-gnocchi password in plaint text. What is the best know method to enable our virtual machines and bare metal instances to send data from collected without exposing the gnocchi password in plain text? Any other output plugin to send that data and avoid the collectd-gnocchi path that is feasible? Thanks for your support.
