Default User Agent used in Web Transaction (Browser) and Web Page Speed (Browser) monitors

Site24x7 Web Transaction (Browser) and Web Page Speed (Browser) monitors use the following user agents for monitoring, 

FFV63 - Mozilla/5.0 (Windows NT 6.3; WOW64; rv:63.0.247) Gecko/20100101 Firefox/63.0.247 Site24x7
chrome - Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36.247 Site24x7

However, you can always specify a custom user agent (browser and version) in your Web Transaction (Browser) and Web Page Speed (Browser) monitor form to simulate different browser versions.
