Avoiding Slowness

  • Don't exaust resources
    • find ways to free up 
    • don't use in parallel unless have enough resources
  • Don't repeat a slow action if result can be stored for faster access
  • Avoid expensive actions
    • if needed do once and store before using in loop
    • keep only what is needed
      • ex: last 5 users who logged on
    • break out of loop when found what is needed

Monitoring Tools

  Most or all tools mentioned from Google Automation: Trouble Shooting & Debugging Coursera course. Resources include: CPU  top shows % cpu used;  system usage; Total should not be more than the # of cores time <call to script or pgm> the memory  memcached the disk IO topio the network connection iftop - monitors bandwidth the graphics card multiple ab -n <times> to get the average timing of <times> requests code profilers profilers are specific to each programming language. So we would use: gprof to analyze a C program c-Profile module to analyze a Python program.   pprofile3 for example: pprofile3 -f callgrind -o profile.out   < call to script or pgm> kcachegrind   a graphical interface for looking into pprofile 3 output files used to see  which functions are called by our program,  how many times each function was called and  how much time are programs spent on each of them. Where and what is the ...

Trouble Shooting & Debugging - Terms & Steps

Notes and basics from Google Automation: Trouble Shooting & Debugging Coursera course Trouble shooting - fixing system Debugging - fixing program code Cache stores data in a form that's faster to access than its original form.   M emory leak -  when memory which is no longer needed is not getting released.  WEEK 2 Videos - review for terms and steps! Debugging Process figuring out the problem and its solution require some creativity.  We need to come up with new ideas of what could be failing, and ways to check for that.  And once we know what's failing, we need to imagine how to solve it.  To take it a step further, once we've solved a problem, we can start thinking about how to prevent it from happening again Steps to solve a problem Gather information super important resource to solve a problem is the reproduction case , which is a clear description of how and when the problem appears Finding the root cause most difficult step.  key: ...
