The Performance Data Collector for HP OpenVMS (TDC) Version 2.3 gathers performance data for Alpha servers running
OpenVMS Version 7.3-2, 8.2, or 8.3 for Integrity servers running OpenVMS Industry
Standard 64 Version 8.2-1, 8.3, or 8.3-1H1. By default, TDC periodically collects and stores data in a file.
Subsequently, user applications can retrieve data from the file.
System managers: The software download link (updated July 2009)
provides a kit to update the Performance Data Collector software (TDC_RT)
installed with OpenVMS Versions 8.2, 8.2-1, 8.3 or 8.3-1H1. You can also use this kit to install Performance Data
Collector software on OpenVMS Version 7.3-2 Alpha systems. Be sure to review the
installation guide before installing the software.
TDC Version 2.3 is primarily a maintenance release of the Performance
Data Collector for OpenVMS software.
The principal goals in providing
this version are to correct defects discovered in TDC Version 2.2 and to provide
the ability to create CSV-formatted (Comma-Separated Values) output files
from TDC data records. This is also the preferred version for developing new performance management applications.
TDC software for OpenVMS Integrity server Version 8.2 is no
longer provided, beginning with the release of TDC Version 2.3.
Therefore, if you are using OpenVMS Integrity server Version 8.2, you should not install this
You can refer the Release Notes Version 2.3-15 that includes a pointer to the software download provided by the Process Software.
The Release Notes Version 2.3-15 can be referred for all versions of TDC starting from Version 2.3.
Software developers: A TDC Software Developers Kit (SDK) is included in the downloadable kit available at the
software download link and can,
optionally, be installed with the TDC software. TDC provides an API that you can use to control all aspects of the
data collection process. This API facilitates integration of your own code with TDC
to perform tasks not handled by TDC out-of-the-box (for example, collecting additional data, utilizing collected
or without first storing it in a file, and analyzing data).
Using the SDK to incorporate TDC into customer applications is supported and encouraged by HP.
The TDC technical overview can help you get started; you can
download it directly, or find it listed along with other programming documentation by following the
software download link. (The documentation is also
included in the SDK.)
