Flow Map
Flow Map
Flow Map is an application-process flow-diagram generator. Flow Map analyzes data
collected by TPDC and Measure and creates a Microsoft Excel based graphical
representation of the applications running on the system, and their performance on the
system. You can create Flow Map diagrams to:
•
Depict the application’s processes, files, and the connections between them.
•
Monitor the actual flow of message traffic within an application. This can help you
understand the performance of applications or uncover application bottlenecks.
•
Show specific detail about the application, or display a portion of the application.
•
View Measure statistics about entities.
Guardian Performance Analyzer (GPA)
GPA is a system performance-analysis tool that analyzes system performance data
collected by Measure. GPA provides tuning recommendations for improving the overall
performance of the system.
You can use GPA to analyze a running system automatically to determine if the system
is balanced and to observe the predicted effects of a processor failure. GPA can provide
the following information:
•
Steps you can take to rebalance the system
•
Processes that are running without backup
•
Processors that do not have adequate capacity to handle the increased load caused by
a failed processor
Using GPA is an iterative process. You run GPA, implement the recommendations that
you choose, then run GPA again to determine the performance improvement and new
recommendations. This process is repeated as frequently as needed for your particular
system and requirements. For example, when predicting the effects of a processor
failure, you run GPA several times following its recommendations until you are
convinced load balancing cannot be improved, then determine if enough processor
capacity exists to handle failure conditions. If there is not enough capacity, you can
reduce the load by moving noncritical jobs to off-peak periods (such as nights or
weekends). If this is not possible, consider purchasing additional processors.
