ptx/PDC V1.5.0 Release Notes


Introduction

ptx®/PDC (Performance Data Collector) is a set of commands and libraries that provide easy access to system performance data on NUMA-Q® systems. The ptx/PDC application programming interface (API) provides a unified method for accessing raw performance data. The ptx/PDC API protects performance measurement products that use the API from changes in the underlying operating system and layered products. It does this by isolating the changes within the PDC itself while maintaining the API used by the products. Products that use the ptx/PDC API will list ptx/PDC as a requirement to run. The ptx/PDC API is currently available for use by third-party application developers, but is not available for general use.

These Release Notes contain the following information:

These release notes do not describe how to use the products that use the ptx/PDC API, such as Datametrics® ViewPointTM. Refer to the documentation for those products for further information.


Compatibility Information

ptx/PDC V1.5.0 is compatible with the following software products running on Symmetry® and NUMA-Q® systems:


Changes Since the Previous Release

This release of ptx/PDC contains bug fixes.


Installation

ptx/PDC must be installed prior to using any products which list ptx/PDC as a requirement.


ATTENTION

If ptx/PDC V1.5.0 is installed on top of a previous version of ptx/PDC using the Delta install and any of the optional layered products (NFS, SVM, EFS and Clusters) are not installed before ptx/PDC installation, the install script will not remove old components corresponding to the layered product. ptx/PDC may not initialize these old components until the corresponding layered products are installed. After installing the layered product, ptx/PDC will initialize the corresponding component properly.


Refer to the DYNIX/ptx and Layered Products Software Installation Release Notes for installation procedures.

Once you have installed ptx/PDC, you can start the data collection daemon (pdcd) by entering the following command:

#/etc/init.d/pdc start

To stop the data collection daemon, enter the following command:

# /etc/init.d/pdc stop

The data collection daemon is automatically started when the system is rebooted and stopped when the system is shut down.


Problem Reports

The number that appears in parentheses in problem report titles is the NUMA-Q Problem Tracking System number assigned to the report.

(251651) PDC Stops Collecting Switch Data if 1 of 2 Switches Fails


Special Instructions for EMC Symmetrix Metrics

ptx/PDC collects EMC Symmetrix metrics through use of a software product from EMC Corporation called the Symmetrix API Runtime and CLI. This product requires additional setup and configuration beyond installation of the ptx/PDC software. The EMC software must be installed and configured prior to using ptx/PDC in order for ptx/PDC to discover and collect EMC metrics.


ATTENTION

The Symmetrix API Runtime and CLI feature that ptx/PDC uses to collect metrics requires a license key from EMC. Please contact EMC for licensing information (http://www.emc.com).


The Symmetrix API Runtime and CLI feature is distributed with EMC's Symmetrix Manager - Base Component product (V4.0.0 and higher) on the Solutions Enabler CD-ROM. The installation process for the software is described in the EMC Solutions Enabler Installation Procedures Product Guide. Use and administration of the software is described in the EMC Solutions Enabler SYMCLI Base Component Product Guide. Contact EMC Corporation to obtain the software and its documentation.
