Name for an HTTP profile. Must begin with a letter, number, or the underscore \(_\) character. Other characters allowed, after the first character, are the hyphen \(-\), period \(.\), hash \(\#\), space \( \), at \(@\), colon \(:\), and equal \(=\) characters. The name of a HTTP profile cannot be changed after it is created.

This option sets the satisfactory threshold (T) for client response time in milliseconds to be used for APDEX calculations. This means a transaction responding in less than this threshold is considered satisfactory. Transaction responding between T and 4*T is considered tolerable.
