| Description | This object describes and configures the agent's support for
application performance measurement for this application.
There are 3 types of measurements for different types of
applications:
Transaction-Oriented applications have a fairly constant
workload to perform for all transactions. The responsiveness
metric for transaction-oriented applications is application
response time (from first request to final delivery of
service) and is measured in milliseconds. This is
commonly referred to as end-user response time.
Throughput-Oriented applications have widely varying workloads
based on the nature of the client request. In particular,
throughput-oriented applications vary widely in the amount of
data that must be transported to satisfy the request. The
responsiveness metric for throughput-oriented applications is
kilobits per second.
Streaming-Oriented applications deliver data at a constant
metered rate of speed regardless of the responsiveness of the
networking and computing infrastructure. This constant rate of
speed is generally specified to be below (sometimes well
below) the nominal capability of the infrastructure. However,
when the infrastructures cannot deliver data at this speed,
interruption of service or degradation of service can
result. The responsiveness metric for streaming-oriented
applications is the ratio of time that the service is degraded
or interrupted to the total service time. This metric is
measured in parts per million.
Note that for some applications, measuring more than one
responsiveness type may be interesting. For agents that wish
to support more than one measurement for a application, they
will populate this table with multiple entries for that
application, one for each type. |
