Advanced WLM usage: Using performance metrics
Supplying data to WLM
Appendix H482
Supplying data to WLM
You supply data to WLM so it can manage SLOs that have performance
goals, shares-per-metric allocations, or condition/exception
statements with metric expressions. You gather this data with collectors
provided by WLM or ones you develop yourself. Data collectors are
specified in the WLM configuration file. WLM spawns the collectors
when the configuration is activated.
Sources for data include:
• ARM (Application Response Measurement) metrics
• GlancePlus metrics
• Oracle database metrics
• Various third-party applications
Metrics can be easily obtained for a number of third-party
applications through the WLM Toolkits (WLMTK). In addition to the
toolkit for Oracle databases, WLMTK provides toolkits for Apache,
BEA WebLogic Server, and SAS.
• Existing application and system metrics you already track
Once this data is collected, it can be sent to WLM in one of two ways:
•WLM wlmrcvdc and wlmsend utilities (which provide a
command-line, shell script, and perl program interface)
•WLM C language API
This chapter covers these topics from two views:
• Data-centric:
I have this type of data. How do I get it to WLM?
• Transport-centric:
I want to get data to WLM this way. What data is available for that
transport method?
