2.2.1 CA MICS Capacity Planner Interface

The CA MICS Capacity Planner provides an interface to assist
clients in performing effective workload forecasting of the
WebSphere Application Server.

The WEB Planning Standard Application uses a capacity
planning database file with the data elements required for
usage reporting and forecasting of the WebSphere Application
Server workload.  It uses the Application Unit (CAPAPU)
feature of the CA MICS Capacity Planner to group the
individual WEB servers into logically similar workload groups
for more meaningful analysis and reporting.  The three
methods for grouping WEB servers together are:

  o defining each WEB server as its own workload group
  o combining all WEB servers (no workload group)
  o defining customized workload groupings.

Each WEB server is uniquely identified by a combination of
its TCP/IP address and port number.  The CA MICS Web Analyzer
includes this information in the key structure for all
timespans of the WebSphere Performance file.  The CA MICS Web
Analyzer also provides additional data elements that can be
used to categorize and identify individual web servers, or
groups of web servers, by their association with workloads,
applications, or other meaningful business or installation
related names.  These data elements can be used to populate
keys in the Capacity Planning database, such as the Capacity
Planning Application Unit (CAPAPU), allowing studies and
forecasts that focus on the business views of the web servers
deployed in your environment.  The following data elements
provided by the CA MICS Web Analyzer should be considered as
candidates for development of keys in a Capacity Planning
database:

  WEBSTYPE - Web Server Type
  WEBSYSNM - System Name
  WEBSRVVR - Server Version
  WEBNAME  - Web Server Long Name (User Defined)
  WEBSNAME - Web Server Short Name (User Defined)
  WEBGROUP - Web Group Name (User Defined)

The CA MICS Web Analyzer provides the following additional
data elements from the CA MICS WebSphere Performance file for
the CA MICS Capacity Planner:

   o  Data elements common to all CA MICS Capacity Planner
      database files:

         SYSID
         ZONE or HOUR
         YEAR
         MONTH or WEEK
         DATE

   o  Data elements unique to the WEB Planning Standard
      Application database file:

         WPRREQR  -  Requests Received
         WPRREQS  -  Requests Sent
         WPRBYTR  -  Bytes Received
         WPRBYTS  -  Bytes Sent

Overall, the integration of the CA MICS Web Analyzer and the
CA MICS Capacity Planner provides a set of tools for
addressing capacity management in the WEB application
environment.
