| Description | This table contains information about each resource owner
in the system.
Each resource owner maintains a list of resource users and
performs the following:
a) Accounting and Thresholding
Accounting and thresholding involves accounting of
resources allocated to each resource user and using
threshold limits for notifying resource user(s) and
resource usage monitor(s) about violations. Accounting
is done by each resource owner.
The ERM framework allows user to configure thresholding
values for each resource owner. When resource utilization
of a resource owner exceeds an applied threshold value,
the resource owner will send notification to relevant
resource user(s).
b) Notifications Sent and Actions Taken
In case of system global thresholding, whenever total
resource utilization of a resource owner exceeds an applied
rising threshold value, the resource owner will send an 'up'
notification to the ERM framework. Whenever total resource
utilization of the same resource owner falls below
the corresponding falling threshold value (after crossing
the rising threshold value), the resource owner will sent
a 'down' notification to the ERM framework.
On receiving the 'up' notification, resource user(s)
is(are) expected to take appropriate action by freeing
the resource or limiting the resource consumption.
The resource owner may restrain from allocating
resource to the resource user(s) in case of the
resource user(s) not taking any action. |
