CA MICS WEB Analyzer Option (WEB) Queries › WEBDRA– Daily Web Server Request Analysis › Uses

Uses

This query generates charts showing daily resource use and performance information about synchronous web requests processed by web servers hosted on z/OS LPARs. At most installations, the use of synchronous requests is far greater than that for asynchronous requests, so it is critical to monitor their quantity, resource use, and performance.

The six CSV data extracts provided by this query provide the analyst with both highly summarized and very detailed insight into z/OS LPAR hosted web server request activity. The SYSID level charts allow daily activity to be viewed with just a few charts. If unusual behavior is noted, the more granular level charts can be used to isolate the specific web server or synchronous request type responsible.

These charts can be used to evaluate specialty processor (zIIP/zAAP) use.

• If excessive CP processor time is being used to process zIIP or zAAP eligible work, it might indicate the need for additional specialty processors.
• If excessive queue time is observed, it might indicate a need for workload balancing. Or specific web servers might need additional resources to help reduce the time waiting for dispatch.

The WLM Response Goal Met charts can assist in fine tuning your WLM Service Policy to ensure that goals and levels of importance are set appropriately.
