Pike Series Release Notes¶
16.0.0¶
New Features¶
Capping the default value for the variable
gnocchi_wsgi_processes
to 16 when the user doesn’t configure this variable. Default value is twice the number of vCPUs available on the machine with a capping value of 16.
The
os_gnocchi
role now includes a facility where you can place your own defaultapi-paste.ini
orpolicy.json
file in/etc/openstack_deploy/gnocchi
(by default) and it will be deployed to the target host after being interpreted by the template engine.
New variables have been added to allow a deployer to customize a gnocchi systemd unit file to their liking.
The task dropping the gnocchi systemd unit files now uses the
config_template
action plugin allowing deployers access to customize the unit files as they see fit without having to load extra options into the defaults and polute the generic systemd unit file with jinja2 variables and conditionals.
For the
os_gnocchi
role, the systemd unitTimeoutSec
value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. TheRestartSec
value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using thegnocchi_*_init_config_overrides
variables which use theconfig_template
task to change template defaults.
Several configuration files that were not templated for the
os_gnocchi` role are now retrieved from git. The git repository used can be changed using the ``gnocchi_git_config_lookup_location
variable. By default this points togit.openstack.org
. These files can still be changed using thegnocchi_x_overrides
variables.
Upgrade Notes¶
For the
os_gnocchi
role, the systemd unitTimeoutSec
value which controls the time between sending a SIGTERM signal and a SIGKILL signal when stopping or restarting the service has been reduced from 300 seconds to 120 seconds. This provides 2 minutes for long-lived sessions to drain while preventing new ones from starting before a restart or a stop. TheRestartSec
value which controls the time between the service stop and start when restarting has been reduced from 150 seconds to 2 seconds to make the restart happen faster. These values can be adjusted by using thegnocchi_*_init_config_overrides
variables which use theconfig_template
task to change template defaults.
Gnocchi service endpoint variables were not named correctly. Renamed variables to be consistent with other roles.
Deprecation Notes¶
The
gnocchi_keystone_auth_plugin
variable has been deprecated.gnocchi_keystone_auth_type
should be used instead to configure authentication type.
