7.3 Solving Application Performance Problems

• Why is the service response time slow recently?
  
• My back-end services failed, but I don’t know which one.
  
• How many kinds of call paths are in my application?
  
• Why is my global distributed transaction completed slowly?
  
• I want to correlate local transactions with remote transactions.
  
• When does my local domain use the most resources from the remote domain, and how busy is it?
  
• Can I check program request information?
