CA MICS WEB Analyzer Option (WEB) Queries › WEBMRA - 30 Day Web Server Request Activity › Uses

Uses

This query generates charts showing the most recent 30 days of resource use and performance information for synchronous web requests processed by web servers hosted on z/OS LPARs. At most sites, 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 three 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 30 days of activity to be viewed for each LPAR with a single chart. If unusual behavior is noted, the more granular level charts can be used to isolate the specific web server or synchronous request type responsible.

For a more detailed analysis, the Daily Web Server Request Activity query (WEBDRA) can be used to closely examine request performance and behavior at the hourly level for specific days where anomalous behavior is noted using this 30 day query.

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.
