If you’re facing difficulties with getting the Session Recorder to work, first take a look at this to learn how to configure your proxy settings. You also need to make sure you do not have any cached files for the site you are about to record.
When clearing your cache, though, make sure that you keep Load Impact’s cookies. Otherwise, you will be logged out of your session. Learn more about caching and cookie clearing here.
If you’ve tried the above and still can’t get it to work, here’s some things you could do to troubleshoot the problem:
The port number for the proxy changes every time you run it, so do remember to update it each time you use the proxy.
(1) The proxy will only ever run for 30 minutes after you have pressed the “start recording” button. After that time has expired, you need to restart it (and probably change your proxy configuration to whatever new port number you’re told to use, though sometimes that can be the same as the old number)
(2) The proxy will stop automatically if it doesn’t see any traffic for 10 minutes. This means that if you start a recording, then go and take a coffee and come back 10 minutes later, you will have to restart the recording. It also means you can’t really spend more than 10 minutes on a single page during a recording session (unless there is e.g. AJAX requests happening regularly in the background while you are viewing the page)
If you have a firewall running, do make sure that these IP addresses (especially our main loadimpact.com IP addresses) are able to access your site.
Check if your system/network administrators limit the ports accessible on your site. Load Impact randomly uses ports between 20000 and 21000 to record sessions, and it is necessary to open the entire range of ports for the recording duration.
