Please anyone advice, can I use Google Analytics to calculate how many number of virutual users do I need for my load testing. How long do I want to run my virtual users? Please advice
In fact you can trust both but Google analytics will provide you more details so if you have to choose one i would suggest Google Analytics.
Google Analytics report may help you to calculate the number of users connecting to your web site.
You can also use your web server logs to get such information or if you already monitor your web server/application server you can get such information.
Thanks Nouredine, Which one do you prefer Google Analytics or Server Logs? I have both of them. Can we trust Google Analytics 100% for doing this calculations.
