Architecture The overall architecture of the Flow Map application is shown in Figure 1-1. First, the

Tandem Performance Data Collector (TPDC) collects the raw Measure 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.
