Troubleshooting performance issues
When you encounter performance issues such as slowness, several tools can help you to target the areas that are causing the issues.
About this task
You can do a performance log analysis by enabling Platform Logging in the IBM® TRIRIGA® Administrator Console. When the logs are generated, you can then analyze the results in a spreadsheet application or SQL table queries.
- Performance Analyzer
- The Performance Analyzer provides a more streamlined approach to troubleshooting performance
issues than the traditional performance log analysis. The Performance Analyzer helps you to better
isolate and analyze the causes of performance issues.
You access the Performance Analyzer in IBM TRIRIGA under Tools. You can generate a log from the Performance Analyzer that is more targeted at the problem area. When you select the performance timings that you want and start a performance run, the analyzer writes to the performance log while you do the process or actions that cause the slowness.
When you stop the performance run, the analyzer automatically loads the performance data and does a high-level analysis that shows the most time consuming events of each category type in the performance run. A result summary of the performance run shows the top events that took the longest time to run. You can further analyze the data by reviewing the result details. You can also upload an existing performance log to the analyzer and the analyzer does the same analysis of the data.

- Workflow Analysis Utility
- You can analyze workflow performance and process execution by using the IBM
TRIRIGA Workflow Analysis Utility. The utility
reads IBM
TRIRIGA performance logs and
displays performance analytics for workflow, which includes workflow execution time and process
flow. The Workflow Analysis Utility is available as a separate utility from the product.
