com.hp.sdn.adm.log.impl.LogManager
The LogManager component controls the number of log message rows displayed in the
Support Logs display. For more information on support log queue size, see
support log queue size ” (page 55)

com.hp.sdn.adm.metric.impl.MetricManagerComponent
The MetricManagerComponent determines how measurement data is maintained by the
controller.
The controller includes a metering framework that internal components and installed
applications can use to collect various types of data. (Data can be persisted on the controller
from sources external to the controller.) Any metric created with the framework might optionally
be persisted over time or directed to the controller JMX facility for viewing. Data persisted
over time can be viewed using the controller REST API, while data sent to JMX can be
viewed using JConsole or another JMX client. The MetricManagerComponent permits
changing default values for certain aspects of the metering framework operation, such as
how long the controller should retain persisted data, at what time of day persisted data that
is too old should be trimmed, and how often persisted metric values should be saved to disk.
(This value can be overridden for any metric when the metric is created).

com.hp.sdn.dvc.impl.DeviceManager
The DeviceManager component serves as an in memory cache for the persistent devices
known to the controller. It holds information about those devices and whether they are
currently connected to the controller. It provides add, update, remove, and get methods for
its devices.
•
com.hp.sdn.link.impl.LinkServiceComponent
The LinkServiceComponent controls the Link Manager service, which serves as an in memory
cache of the links known to the controller. It provides add, update, remove, and get methods
for its links.
◦
The
cache.size
configurable parameter allows you to specify a maximum number of
links that can be stored by the Link Manager. Default is 20,000.
•
com.hp.teaming.imple.CassandraProcessManager
The CassandraProcessManager component controls configuration parameters of the
Cassandra database.
•
com.hp.sdn.teaming.impl.TeamConfigurationManager
The TeamConfigurationManager component manages the configuration of team
communication. When one of the components’s keys is modified, the administrator must
wait for the new value to be forwarded to the other members of the team (this can be
confirmed by making sure the change appears in the UI of each controller), and then ALL
controllers must be restarted.
