1 TPDC Overview
The Tandem Performance Data Collector (TPDC) is an HP host-based performance
data collection and relationship product for HP NonStop Kernel systems. TPDC
significantly reduces the expertise and manpower required to collect performance data.
It provides an all-in-one approach to collection and integration of performance
information.
One of the challenges in performance analysis is making sure that you have all the
data necessary to perform the analysis successfully. To correctly evaluate
measurement data, you need several pieces of information. You need to:
•
Know the configuration of software and hardware components on the system.
•
Make sure that no dynamic changes take place during the period measured.
To acquire all this information on a NonStop Kernel system requires the use of several
software tools, which you do not need to access directly with TPDC: Measure, FUP,
PUP, PEEK, SCF, and DSAP.
By carefully coordinating the scheduling and execution of these tools, you can get
accurate information about the running environment and items in the period of interest.
You can defer processing to times when system resources are more available, and you
can measure small intervals within a measuring period for greater levels of detail.
Unfortunately, the data from these different tools is not in a consistent format for
analysis. A lot of the data (from FUP, PUP, PEEK, SCF, and DSAP) is in ASCII report
format instead of data structures, which makes relating the data difficult. Also, report
data formats could change in certain tools, which could further complicate matters.
TPDC collects the data from all these sources and consolidates it into a single,
consistent data source so you can analyze all the information for a measured period
together.
