Flow Map
Flow Map
The Flow Map product is a performance-analysis tool with two components, Flow Map
Host (FMH) and Flow Map PC (FMP). FMH filters, reduces, and formats performance
data collected by the Tandem Performance Data Collector (TPDC) and Measure
products. FMP is a Windows workstation graphical user interface. It creates a flow
diagram showing how the processes, files, and connections of an application running on
the Tandem system interact.
Using Flow Map for Performance Analysis Tasks
Since Flow Map creates flow diagrams directly from data collected and reduced on the
host, it always gives an up-to-date representation of an application. Flow Map can help
you to:
•
Document a working version of your application
•
Find the actual flow of message traffic within the application
•
Compare the actual flow to what was intended
•
See the interaction of the application with other activities on the system
•
Troubleshoot performance bottlenecks and research performance problems
•
Review performance and optimize application processes and files and the message
flow between them
•
Plan capacity
How Flow Map Works
First TPDC collects the raw Measure data and other performance data from the Tandem
host and puts it into a consolidated data file. Next, FMH filters, formats, and reduces the
data and creates a Flow Map Host Sample. Finally, Flow Map PC receives the Flow Map
Host Sample and creates a diagram from the downloaded data. Figure 9-3 illustrates the
Flow Map architecture.
Where to Find More Information About Flow Map
Flow Map is described in the Flow Map Manual.
Note. Both the TPDC and Measure products are described later in this section.
