This is a good course on troubleshooting and debugging. I think the subject is so vast that the deeper aspects of performance may not be covered at the hardware level or application level. Scenarios with cloud and on-premise examples would have been great. If there is a broader course covering these concepts of performance in on-premise and cloud would be great.

The course itself was very informative, and you learn really to use cool methods, tools, and get a solid explanation of how to approach troubleshooting and debugging techniques. A downside: Qwiklabs assessments was either too easy, or as in week 4 disconnected material and therefore way too hard for me. Learned a lot, 4 out of 5!

Good class. Take notes and record the commands used in the online exams. Instead of trying to duplicate the programs, debug your own to explore the commands discussed. The section on Linux Performance Observability and Performance Tuning Tools is most useful. I wrote a program to process the video text for important items.

Great course! The only reason im giving 4 stars is because there were many times I wished I could play around with the scripts Amanda was using but I couldn't download it on my pc. Other than that, it was a very informative course, loved learning about the different troubleshooting and debugging techniques.

T​he course provides a good overview on debugging and troubleshooting and in some cases deeper insights into Linux commands that help to pinpoint the root cause of a problem. However, some of the quizzes and especially the labs are too easy and in some cases don't match the course content well.

The content was good and it was presented well. There is very little Python in this course and some is above the specialization (so far) and some is much more approachable. While troubleshooting and debugging are very important, this course seemed focused on such a wide set of potential issues.

The structure of the course is very good, many subjects are treated in a didactic and striking way. There is confusion in the practice exercises, it is recommended to improve them. Otherwise, I think it is a very good course.

there were some elements in the code where based on information given and research asked the praticals required an advanced understanding. Am still deciding if that was a good or bad thing. Otherwise it was brilliant

It is very interesting course, I like the course material, the organisation and the way it was presented.

However, the last lab assessment had some issues and took me more than a week for the issues to be resolved.

A lot of information and tools to fix typical problems in IT environments. The course goes not deep because some subjects would take entire courses, so it's a good big picture course.

Knowledgeable content, but they should show more practical exercises and after taking 2-3 test of students on practical knowledge, they should give him the graded assessment.

All but the last lab were cut and paste, but the last lab was great, getting a hint but having to think about the solution using the tools learned in the course.

It is a helpful course to learn how to debug possible issues in your computer. A must do for a person looking for improving their troubleshooting skills in IT!

Super fun and very interesting. The lessons at the end were very dry, but I could see how they would help those who have trouble managing their time.

This course is interesting and covers a lot of things. The only thing that would be beneficial is to have more homework assignments or quizzes.

Nice course with good instructor. More conceptual than practical, but still gives us good advices for troubleshooting and debugging.

practical exercises doing each week by the host I think should be proper to adapt to the learners to replicate it at the same time

it was more of a theory based course, very less practical things to experience, as well as week 2 lab was not properly explained

Excellent lab. Enjoyed making my script run faster than the original case and learning the power of avoiding expensive loops

a bit hard but challenging, i met some trouble while doing this course such as the quiz seems bugged when i enter my code

please include more detail and feedback on the graded assignments. so it give detail that which part should be improved.

M​uy interesante por mostrar un método consistente a la hora de tomar contacto con los problemas reales en entornos TI.

Could have included more practice exercise and information on the subject. Overall i felt it was small, simple and Fun

The course is very helpful it covers a wide range of troubleshooting concepts, it would be better with more examples

interesting course, good concepts, graded exercises vacillated between being too easy and very challenging
