This commit was bulk generated and pushed by the OpenDev sysadmins as a part of the Git hosting and code review systems migration detailed in these mailing list posts: http://lists.openstack.org/pipermail/openstack-discuss/2019-March/003603.html http://lists.openstack.org/pipermail/openstack-discuss/2019-April/004920.html Attempts have been made to correct repository namespaces and hostnames based on simple pattern matching, but it's possible some were updated incorrectly or missed entirely.

python-oneviewclient
Library to use HPE OneView to provide nodes for Ironic
This library adds a communication layer between Ironic and OneView and abstracts the version of OneView in place.

Features
Audit logging
python-oneviewclient is capable of logging method calls
to OneView for auditing. Currently, data about request timing and method
names, parameters and return values, can be recorded to be used in the
auditing process to discover and better understand hotspots, bottlenecks
and to measure how the user code and OneView integration performs.
Enabling audit logging
To enable audit logging, the user code has to set three parameters in
the constructor of the client object. namely:
audit_enabled, audit_map_file and
audit_output_file. audit_map_file and
audit_output_file must be filled with the absolute path to
the audit map file and the audit output file.
The audit map file
The audit map file is composed of two sections, audit
and cases. In the audit section there should
be a case option where one, and just one, of the audit
logging cases needs to be specified. The cases
section needs to be filled with a name for a case followed by the
methods that the user wants to audit logging. The methods that are
allowed for the audit logging are those decorated by
@auditing.audit in python-oneviewclient.
See an example of an audit map file:
[audit]
# Case to be audit logged from those declared in cases section.
case = case_number_one
[cases]
# Possible auditable case name followed by the audit loggable
# methods' names.
case_number_one = first_method,second_method,third_method
case_number_two = first_method,third_method,fifth_methodThe audit output file
The result of the audit logging process is a JSON formatted file that
can be used by auditors, operators and engineers to obtain valuable
information about performance impacts of using
python-oneviewclient to access OneView, and better
understand possible hotspots and bottlenecks in the integration of the
user code and OneView.
See an example of an audit output file:
