PM/400e Integrated with Workload Estimator (Service Offering)

PM/400e is a personalized tool shipped with OS/400 that gives you easy-to-use reports about
the performance of your systems. You simply turn the tool on and access your reports on the
Web. These reports automate many of the functions associated with capacity planning and
performance analysis. The personalized Web-based reports help identify potential resource
constraints as well as help you plan future growth.
The ability to run PM/400e and Service Agent over TCP/IP using the integrated high-speed
V.90 modem is added as of V4R5. In addition, the ability to inventory multiple systems
hardware and software information is enabled over this connection. You can check the
following Web site for the PTFs that are required to enable these functions:

The Workload Estimator currently helps you size system needs based on estimated
workloads for specific workload types. The Workload Estimator and PM/400e now work with
one another. Through a Web-based application, the enhancements helps you size upgrades
to your existing system based on PM/400e reported utilization, performance, and growth
data. Plan your future system requirements based on existing utilization data.
Sizing for additional workload types supported by the Workload Estimator (for example,
Domino, WebSphere, Java, and others) can also be included in the sizing. With the flexibility
to adjust growth rates and time horizons, the output will include an AS/400 and iSeries
summary level recommendation for your consideration. It includes a suggested upgrade for
your processor, processor features, memory, disk arms, and disk capacity.
PM/400e reports are enhanced to be even more meaningful in today's rapidly changing
system environments and to better reflect usage and trends at a partition level. The
enhancements include changes to:
• The basis on which PM/400e reports are calculated (normalization): The basis
used for all historical and predicted data is the relative Commercial Processing
Workload (CPW). Using CPW to plot workload demand provides a more accurate
reflection of workload changes even if a processor upgrade has taken place. The
workload demand is especially useful to note in a logical partition environment, to
observe the amount of processing power used across partition changes.
• Trending: PM/400e now includes trend lines for processor and disk utilization based
on the previous three and six months of historical data. This allows you to more easily
see rapid changes to utilization over a short period of time and to evaluate your growth
and business needs based on your most recent information
• Actual maximum number of observed jobs: PM/400e now includes the maximum
number of observed jobs at IPL and what level of jobs the system eventually reached.
Along with the system value settings, this can help you tune your system to avoid
periods of high response times immediately after an IPL.
