A common problem performance analysts encounter is high CPU utilization on a server or application without the ability to identify the root cause of the problem quickly and easily.
Without a quick resolution, this CPU usage can become costly, quickly. This video provides an overview of how to navigate, analyze, and monitor your WebSphere processor usage, from the Cell level all the way down to individual applications.
Monitor WAS Processor Usage
In this video we begin our investigation into our WebSphere utilization by noticing that one cell consumes significantly more processor resource than the other cells.
Our investigation then leads us through different cell views, down to the specific URI consuming the most CPU.
Managing any workload on z/OS requires resource consumption data. Monitoring your WebSphere processor usage will help you:
- Understand your workload utilization patterns by time of day, day of week, and more for capacity planning and performance management
- Isolate high utilization issues by system/cell/cluster/node/server/servant/transaction class/URI
- Identify changes to an application by tracking CPU/transaction
- Identify workload eligible for zIIP offload
- Compare different time intervals, to assess the impact of planned or unplanned changes
- Perform trending and statistical analysis for capacity planning
In the video, you will see predefined reports for CPU and zIIP utilization by cell and by URI, along with drill down functionality for more detailed data. Transaction rates and response times are also correlated to resource utilization by time over a busy day.
We also demonstrate some of the ease of use features of IntelliMagic Vision, including chart editing and ways to quickly share information with colleagues such as:
- Links to charts
- Exporting PDF, PowerPoint, CSV or to Splunk
- Collected reports
- Dashboards – both personal and shared
White Paper: Monitor the Performance and Resource Usage of WebSphere Transactions
Download this white paper to see how you can get instant access to key WebSphere metrics and a more detailed look at how to monitor the performance and resource usage of WebSphere transactions.
Monitor WebSphere Data Volumes
This video introduces the topic of transaction reporting based on the SMF 120 subtype 9 record, specifically in terms of data volume per request/response.
Monitor WebSphere Response Times
This video introduces the topic of transaction response time reporting based on the SMF 120 subtype 9 record.
Monitor WebSphere Transactions
Each request that comes into WebSphere is considered a transaction and can be reported down to the level of URI name. These URI’s give you the names of specific resources or applications requested, and each individual request is logged.
