HP-UX Workload Manager overview

Methods for collecting data include:

• Glanceplus data collectors (included with WLM)

• WLM Oracle® data collector and WLM data collectors for other third-party applications

• Scripted data collectors launching the wlmsend command

• Scripted or binary data collectors providing data on stdout

• Binary data collectors providing data through the native WLM data collection API

The data is available from many sources:

• Glanceplus metrics—You can use these metrics by specifying one of the Glanceplus data collectors

in your configuration file. These data collectors are included with WLM.

• Oracle database metrics—You can retrieve these metrics using the WLM Oracle data collector,

which is part of the WLM Toolkits (WLMTK) that come free with WLM. For more information about

WLMTK, see the white paper, “WLMTK Overview: Using HP-UX Workload Manager most

effectively with your critical applications” at

http://h20338.www2.hp.com/hpux11i/wlm.toolkits.pdf.

• Various third-party applications—You can obtain metrics for a number of third-party applications

through the WLMTK. In addition to the toolkit for Oracle databases, WLMTK provides toolkits for

Apache, BEA WebLogic Server, SAP, and SNMP.

• Existing metrics—If you already maintain application- or system-specific metrics, you can use that

data.

• Dummy transactions—You can use these transactions to give a rough feel for the application

performance. These transactions require the same types of processing as the real transactions of

interest. The process generating the dummy transactions would then report the performance to

WLM.

• ARM-instrumented applications—You can use the wlmrcvdc utility with the glance_tt command

to send WLM any data collected by an ARM agent. ARM

is the Application Response

Measurement standard for application instrumentation.

After the data is collected, it can be sent to WLM in one of two ways:

• WLM wlmrcvdc and wlmsend utilities (which provide command line, shell script, and PERL

program interfaces)

• WLM C language application programming interface (API)
