Hi Poh:
There is an old but but very good reference on APM Reporting. After a six year effort, there is a link to it in teh documentation:
Key parts:
What you can get from the report:
One of our transactions has a much lower success rate than the others. What are the factors affecting that success rate which is independent of other monitored transactions?
Definition:
The Success Rate is the percentage of defect-free transactions. Defects include slow transaction times, incomplete transactions, missing components and other problems, though being defective does not necessarily mean that the transaction did not complete. The Success Rate SLA is a target for the defect-free transactions. At the business process level, this is an average success rate for all transactions within the business process.
The results are ranked based on the success rate, with the lowest success rate on top, assuming that is the area of greatest concern
So you can see which transactions are generating the most defects (which may be false positives)
Let me know if there are followup questions
Thanks
Hal German
