New SB driver for commodity servers
Monitoring enhanced with timing stats
Copy constructors for Rx filter values
Driver is updated to provide port statistics to the REST SB controller
Drastic changes to make the driver ONOS compliant. NIC statistics have become 100% compliant with PortStatistics
CPU statistics also compatible with the ONOS approach
Separated timing statistics
Style fix
NIC is included
Proper representation of a CPU. Also some refactoring
Removed unused import and added important comment
CPU vendor has become a class and the servers are now reporting more detailed CPU info
Fixed port statistics' counters for servers
Various fixes that lead to more stable behavior
Additional checks to avoid null pointer exception
Fixed potential casting issues
Updated pom with affiliation information
Updated pom with URL
Bumped rivers to version 1.12
Updated BUCK for version 1.12
NIC speed has become long and NICs are retrieved in a sorted fashion
Fixed warning
Timing statistics contain autoscale measurements
Fixed CPU vendor ID for Intel
Bumped Metron's drivers to version 1.13. Fixed origin and URL in pom.xml
Updated RestServerSBDevice to comply with the extended ONOS RestSBDevice
Total refactoring of the driver to become more generic (NFV -> Server).
Also properly separated the statistics API from implementation.
Refactored server driver and bug fix that occured when port statistics
were called before a device is properly discovered.
Statistics API and implementation are grouped again.
Removed unnecessary stuff from pom and BUCK files
Fixed checkstyle warning
Added short readme to pom.xml
New ControllerConfig behavior added
This patch adds an new ControllerConfig behavior to the server
driver, allowing external applications to get, set, and remove
a server's controller configuration.
Common functions and variables are also shared between the
two basic modules of the driver.
Fixed checkstyle warnings
Refactored controller configuration module
Consistent values returned by the methods of the driver
Unit tests for ServerControllerConfig behavior
Fixed preconditions for NULL and arguments
Improved documentation
Updated pom and BUCK
Addressed comments about sharing some more methods
Refactored the Common.java to become a base class
that extends AbstractHandlerBehaviour and can share
a unique instance of the RestSBController with child
classes. Also, after the removal of some deprecated
methods of the HTTP SB controller, I had to perform
some compatibility changes in the respective methods
of this driver.
The only problem is that my tests are now broken(??)
and I had to remove their code for now until I fix
the issues.
Expose some members and methods of BasicDriver
Renamed BasicDriver to BasicServerDriver
