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

Overview

The WEBDRA query generates a series of data extracts that support the daily analysis of synchronous web server requests, processed by z/OS hosted web servers, at a variety of summarization levels. At the highest level, the overall daily resource use and performance information for each z/OS system in a Central Processing Complex (CPC) can be viewed in a single chart. At an intermediary level, individual charts display the same information at the web server level.

And at the lowest level, individual charts are generated for each type of synchronous request (HTTP, INTERNAL, MBEAN) processed by individual web server for each hour of the day.

Six CSV output files are generated by the query.

• The first, third, and fifth CSV output files generate charts showing the overall daily resource usage and performance information for synchronous web requests at the z/OS system (SYSID), web server, and request type summarization levels, respectively.
• The second, fourth, and sixth CSV output files generate charts at similar summarization levels, but show the resource usage and performance information for each hour of the day.

The six CSV data extracts generated by the WEBWRS query are:

(1)  Daily Web Server Analysis SYSID  Summary
(2)  Daily Web Server Analysis  SYSID by HOUR
(3)  Daily Web Server Analysis  Web Server  Summary
(4)  Daily Web Server Analysis  Web Server by HOUR
(5)  Daily Web Server Analysis Request Type Summary
(6)  Daily Web Server Analysis Request Type by HOUR

Each summary CSV data extract (1, 3, and 5) generates the following four chart views:

• Daily Web Server Summary – granularity Level Requests Processed
• Daily Web Server Summary – granularity Level CPU Use
• Daily Web Server Summary – granularity Level WLM Response Goal Met
• Daily Web Server Summary – granularity Level Response Time

  where granularity is SYSID (CSV–1), Server (CSV–3), and ReqType (CSV–5)

Each "by HOUR" CSV data extract (2, 4, and 6) generates the following four chart views:

• Daily Web Server by HOUR – granularity Level Requests Processed
• Daily Web Server by HOUR – granularity Level CPU Use
• Daily Web Server by HOUR – granularity Level WLM Response Goal Met
• Daily Web Server by HOUR – granularity Level Response Time

  where granularity is SYSID (CSV–2), Server (CSV–4), and ReqType (CSV–6)
