results were achieved. The following monitors are available for drill down in the EWLM
Control Center:
? Performance Index Monitor
? Goal Achievement Monitor
? Transaction Count Monitor
? Transaction Rate Monitor
? Processor Usage Monitor
In addition to monitor drill down, you can also drill down from the service class, transaction
class, or process class to get a server or application topology view. The application topology
view provides a diagram of applications that processed transactions for a particular class. The
server topology view provides a diagram of the managed servers that processed transactions
for the particular class. These views provide a transaction workflow in a heterogeneous
environment.
Detailed reporting provides performance data for domain policy components, for example,
workloads, service classes, transaction classes, process classes, or managed servers. The
following detailed reports are available in the EWLM Control Center:
? Managed server details
? Service class details
? Process class details
? Transaction class details
1.2.4 Domain policy
An EWLM Domain Policy provides a solid context to associate relevance of all other statistics
collected. It is a contract which prescribes how EWLM should treat work within a
management domain. This includes how the work can be classified, prioritized and
monitored. Management of work, meaning taking action based on performance statistics, in
this release is only available in conjunction with Cisco Systems Inc. load balancer.
A Domain Policy is a collection of service policies, applications, transaction classes, service
classes, and optionally platforms and process classes for an EWLM Management Domain.
As you can see in Figure 1-6, a Domain Policy can have an unlimited number of service
policies (in the sample you have Weekend and week day), but only one service policy can be
active at a given time in the domain. You can have multiple service policies which have
performance goals that are specific to a certain time of day or week and these policies can be
activated as needed. Only one Domain Policy is needed for a domain because it contains all
the service policies for the domain.
