F5 BIG-IP Troubleshooting
Troubleshooting Principles
Define the problem -- What exactly is broken? Who reported it? What is the expected vs actual behavior?
Gather facts -- List objects, check stats, read logs. Never assume.
Consider possibilities -- Based on facts, list likely root causes
Create action plan -- Test one variable at a time
Implement and verify -- Make one change, verify, document
Document -- Record what was found and what fixed it
