Using Scientific Method for Troubleshooting

Efficient and timely troubleshooting skills can be developed through practice of the widely recognized   scientific method . The scientific method is an empirical process for using logic to hypothesize and test theories through observation, refined by experimentation and validation of deductions that are drawn from those hypotheses. With experience, scientific method users acquire knowledge and develop useful conclusions through refinement and elimination of tested hypotheses. The scientific method consists of these steps: Collect relevant information. Create an accurate problem statement. Formulate testable hypotheses. Test each hypothesis. Record and analyze the test results. Fix and verify the problem resolution. Using the Scientific Method In many scenarios, you might repeat the scientific method, either in whole or by iterating on certain steps, to discover and verify the root cause of the problem. Collect relevant information. The first step, before theorizing a problem state...

What to look at when there is an OS Error in Linux

 /var/log folder contains overall system notifications and messages recorded at system boot.
