Logging settings¶
Networking components use Python logging module to do logging. Logging configuration can be provided in neutron.conf or as command-line options. Command options override ones in neutron.conf.
To configure logging for Networking components, use one of these methods:
Provide logging settings in a logging configuration file.
See Python logging how-to to learn more about logging.
Provide logging setting in neutron.conf.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
[DEFAULT] # Default log level is WARNING # Show debugging output in logs (sets DEBUG log level output) # debug = False # Show more verbose log output (sets INFO log level output) if debug is False # verbose = False # log_format = %(asctime)s %(levelname)8s [%(name)s] %(message)s # log_date_format = %Y-%m-%d %H:%M:%S # use_syslog = False # syslog_log_facility = LOG_USER # if use_syslog is False, we can set log_file and log_dir. # if use_syslog is False and we do not set log_file, # the log will be printed to stdout. # log_file = # log_dir =
Notifications¶
Notifications can be sent when Networking resources such as network, subnet and port are created, updated or deleted.
Notification options¶
To support DHCP agent, rpc_notifier driver must be set. To set up the notification, edit notification options in neutron.conf:
1 2 3 4 5 6 7 | # Driver or drivers to handle sending notifications. (multi
# valued)
#notification_driver=
# AMQP topic used for OpenStack notifications. (list value)
# Deprecated group/name - [rpc_notifier2]/topics
notification_topics = notifications
|
Setting cases¶
Logging and RPC¶
These options configure the Networking server to send notifications through logging and RPC. The logging options are described in OpenStack Configuration Reference . RPC notifications go to notifications.info queue bound to a topic exchange defined by control_exchange in neutron.conf.

# Notifications can be sent when network/subnet/port are create,
updated or deleted.
# There are three methods of sending notifications: logging
(via the log_file directive), rpc (via a message queue) and
# noop (no notifications sent, the default)
# Notification_driver can be defined multiple times
# Do nothing driver
# notification_driver = neutron.openstack.common.notifier.
no_op_notifier
# Logging driver
notification_driver = neutron.openstack.common.notifier.

# default_notification_level is used to form actual topic
names or to set logging level
default_notification_level = INFO
# default_publisher_id is a part of the notification payload
# host = myhost.com
# default_publisher_id = $host
# Defined in rpc_notifier for rpc way, can be comma-separated values.
# The actual topic names will be %s.%(default_notification_level)s
notification_topics = notifications
# Options defined in oslo.messaging
# The default exchange under which topics are scoped. May be
# overridden by an exchange name specified in the
# transport_url option. (string value)
#control_exchange=openstack
|
Multiple RPC topics¶
These options configure the Networking server to send notifications to multiple RPC topics. RPC notifications go to notifications_one.info and notifications_two.info queues bound to a topic exchange defined by control_exchange in neutron.conf.
