3 1 Abstract This manual explains step by step how to record HTTP(S) traffic from any iphone and ipad by using an Apica ProxySniffer "Pure Cloud" machine that runs in the Amazon EC2 cloud. After the recording of a Safari Web browser session, or the recording of HTTP/S traffic generated by any ios application, has been done the captured data can be automatically converted into a load test program. Such a load test program can then be executed from cloud-based load generators that are able to simulate 200,000 virtual users or even more. You need: - An iphone or an ipad connected to the Internet (by any provider, WLAN or 3G/4G), from which the HTTP(S) traffic will be recorded. - An Amazon AWS Account (register at aws.amazon.com if you don t have such an account). - A notebook or a desktop computer running Windows or Mac OS X, connected to the internet, used to start and access an Apica ProxySniffer "Pure Cloud" machine on Amazon EC2. Note that your notebook or a desktop computer is only used to start and access the "Pure Cloud" machine. All other tasks like recording and postprocessing of load tests, starting of load generators and performing of load tests can be made from the "Pure Cloud" machine. Even when you stop (terminate) your "Pure Cloud" machine all of your data are safely stored on a cloud-based disk and can be reused when you start later another "Pure Cloud" machine Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 3 of 21

4 1.1 How Much Does It Cost? The recording of HTTP(S) traffic from an iphone or ipad do not require to purchase a ProxySniffer license, and you can also execute small load tests with up to 20 virtual users form a "Pure Cloud" machine for free. This means that you have only to pay for the "basic" Amazon AWS costs that are: Between 1.00 and 1.90 USD * (+ I/O: USD 0.14 per 1 million I/O requests) per month for a cloud-based Data Disk. Between 1.14 and 1.60 USD * per hour for running a "Pure Cloud" machine. * = depending on the geographic location the Amazon data center. The amount is charged by Amazon. Recording of HTTP(S) traffic from an iphone or ipad and executing small load tests is inexpensive. However, keep in mind that you have manually to terminate (stop) your "Pure Cloud" machine after you have performed your load test (in order to avoid unnecessary Amazon AWS costs). Additional costs occur if you wish to rent strong cloud based load generators.

5 2 Step by Step Instructions 2.1 Step 1: Install ProxySniffer on your Notebook or Desktop Computer Download the ProxySniffer installation kit from You require ProxySniffer version 5.0-K dated from November 18, 2012 (or a newer version). After that start on your local notebook or desktop the "ProxySniffer Console" and then start the "ProxySniffer GUI". 2.2 Step 2: Launch (Start) a "Pure Cloud" Machine Click on the "Pure Cloud" icon in the ProxySniffer GUI and follow the instructions described in "Pure Cloud" Manual: If you don t have a "Pure Cloud" data disk you have first to create such one before you can launch a "Pure Cloud" machine. Note: When launching a "Pure Cloud" machine you must enter an arbitrary password used for accessing the machine and you must manually enable the checkbox "Enable Proxy Recorder (port 7999 and HTTP and HTTPS/HTTP Proxy". All other checkboxes should also be enabled: 2012 Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 5 of 21

6 2.3 Step 3: Login into the "Pure Cloud" Machine and Copy the ProxySniffer Root Certificate to D:\MyTests After your "Pure Cloud" machine is started login into the machine by using the user account PrxUser and the password that you have configured when launching the machine. Then copy on the "Pure Cloud" machine the file root.cer from C:\ProxySniffer to D:\MyTests (which is your cloud-based disk). Note: in case if you have created your own root certificate as described in the installation manual you should first upload your files root.cer and privkey.der and replace them in C:\ProxySniffer. After that reboot the "Pure Cloud" machine before you copy the file root.cer to D:\MyTests Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 6 of 21

7 2.4 Step 4: Import the ProxySniffer Root Certificate into your iphone or ipad Start the Safari Web browser on your iphone or ipad and enter name of Pure Cloud Machine>:81/MyTests/root.cer To authenticate yourself against the WebDAV server running on the "Pure Cloud" machine enter the user account PrxUser and the password that you have configured when launching the machine Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 7 of 21

10 2.5 Step 5: Configure the Proxy Settings on your iphone or ipad Configure as Proxy Server the DNS name of your "Pure Cloud" machine and configure the Proxy Port From now on all HTTP(S) traffic of the iphone or ipad flows via the "Pure Cloud" machine, meaning that you are now ready to record such data Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 10 of 21

11 2.6 Step 6: Record HTTP(S) Traffic from the iphone or ipad Logon again into your "Pure Cloud" machine by using Remote Desktop, then start the ProxySniffer GUI on that machine and start the recording by clicking at the icon in the ProxySniffer toolbar: 2012 Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 11 of 21

12 Then switch to your iphone or ipad and perform the steps that you want to record. Note: during recording we recommend that you always insert a "Page Break" at the ProxySniffer GUI on the "Pure Cloud" machine - each time before you record a next step on the iphone or ipad: 2012 Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 12 of 21

14 After that you should save your recorded session on the "Pure Cloud" machine to your attached "Pure Cloud" data-disk: 2012 Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 14 of 21

15 3 Further Steps 3.1 Post-Process the Recorded Data Please to read the Proxy Sniffer User's Guide starting from chapter Normally you have to post-process the recorded data before converting them into a load test program. We recommend that you also take a look at the manual about Handling of Dynamically-Exchanged Session Parameters Verify the Proper Functionality of your Load Test You can perform small load tests directly from the "Pure Cloud" machine for free. This allows you to verify the proper functionality of your load test before you spent money for renting powerful cloud-based load generators. 3.3 Rent Powerful Cloud-based Load Generators and Perform Large Load Tests To rent powerful cloud-based load generators follow the instructions in the Generating Load from the Cloud Handbook. Keep in mind that you should start the cloud-based load generators always from your "Pure Cloud" machine (don't start them from your local notepad or desktop computer) Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 15 of 21

16 4 Reset the Configuration on the iphone or ipad After the recording of a load test has been done you should reset the configuration on the iphone or ipad. A) Disable the Proxy Settings on the iphone or ipad: 2012 Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 16 of 21

17 B) Un-install the ProxySniffer Root Certificate on the iphone or ipad: Note: in case if you have used your own root certificate created as described in the installation manual there is no need to un-install your root certificate. However, if you have installed the generic ProxySniffer root certificate we strongly recommend that you un-install this certificate to keep your iphone or ipad secure Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 17 of 21

18 5 Terminate (Stop) the "Pure Cloud" Machine After the load test has been performed and after you have acquired and analyzed the load test results you shouldn't forget to terminate (stop) your "Pure Cloud" machine in order to avoid unnecessary Amazon costs. All of your data are safely stored on the cloud-based data-disk and can be reused when you start later another "Pure Cloud" machine Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 18 of 21

19 After the "Pure Cloud" machine has terminated you can also delete the cloud-based data-disk. However, in such a case all of your data are lost. Note that the Amazon costs are only between 1.00 and 1.90 USD per month for a cloud-based data disk. Therefore it's not recommended that you frequently delete and re-create cloud-based disks Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 19 of 21

20 To verify that all cloud-based machines, load generators and data-disks are stopped you take a look at the bottom of the window where a corresponding statistic is displayed: 2012 Ingenieurbüro David Fischer AG, Switzerland All Rights Reserved Page 20 of 21
