Example Configuration File
for nova
This sample configuration file demonstrates how the OpenStack compute service (nova) might be configured.
nova_sample.conf
Two logger nodes are set up, root and
nova.
nova_sample.conf
Several handlers are created, to send messages to different outputs.
nova_sample.conf
And two formatters are created to be used based on whether the logging location will have OpenStack request context information available or not. A Fluentd formatter is also shown.
nova_sample.conf
The root logger is configured to send messages to the
null handler, silencing most messages that are not part of
the nova application code namespace.
nova_sample.conf
The nova logger is configured to send messages marked as
INFO and higher level to the standard error stream.
nova_sample.conf
The amqp and amqplib loggers, used by the
module that connects the application to the message bus, are configured
to emit warning messages to the standard error stream.
nova_sample.conf
The sqlalchemy logger, used by the module that connects
the application to the database, is configured to emit warning messages
to the standard error stream.
nova_sample.conf
Similarly, boto, suds, and
eventlet.wsgi.server are configured to send warnings to the
standard error stream.
nova_sample.conf
The stderr handler, being used by most of the loggers
above, is configured to write to the standard error stream on the
console.
nova_sample.conf
The stderr handler uses the context
formatter, which takes its configuration settings from
oslo.config.
nova_sample.conf
The stdout and syslog handlers are defined,
but not used.
The fluent handler is useful to send logs to
fluentd. It is a part of fluent-logger-python and you can
install it as following.
$ pip install fluent-loggerThis handler is configured to use fluent formatter.
