Tandem Performance Data Collector (TPDC)
Tandem Performance Data Collector (TPDC)
The TPDC main component collects performance data and creates the consolidated
performance data file. The unstructured consolidated performance data file contains all
the data you need for subsequent analysis and reporting.
The general layout of the consolidated performance data file is:
A version header that contains the version date, index entry count, length, and
other identifiers
Index entries that contain the entity name, type, count, and length
Entity entries that contain the performance data
Tandem Performance System File Label (TPSFL)
The TPSFL component interrogates all disk directories on a system and records label
information. TPDC conditionally invokes TPSFL during its execution, or you can invoke
TPSFL as a standalone facility to create data files with file label information. (Due to
processing demands, TPSFL should only be run once per day, when system resources
are in less demand.) TPSFL can generate these reports:
Volume Label Report
Device Distribution Report
Logical Device Report
Disk Report
Tandem Performance File Label (TPFL)
The TPFL component obtains this label information for open files from the files created
by TPSFL:
Disk file labels (FLABEL file)
Alternate keyfile labels (ALTKFILE file)
Partition file labels (PARTFILE file)
If (as an exception) TPSFL files do not have label information, TPFL reads the disk
directory for the information directly.
You cannot execute TPFL directly. TPFL is run automatically by TPDC.
Tandem Performance Load Measure (TPLM)
The TPLM component loads the consolidated data and creates Measure entities, from
which you can generate optional reports using GPA and other programs.
