Web Transaction (PI_WT)

Function

The Web Transaction (PI_WT) record stores information about a Web transaction service response time. This is a multi-instance record. Each scope becomes an instance.

Web transaction operating environment and notes

A Web transaction probe performs not only a measurement consisting of a single set of a request and a response but also a measurement in which a series of HTTP(S) requests and responses constitute a single Web transaction.

A Web transaction's measurement result covers the playback of the entire Web transaction. A measurement result is also output for each specified scope (any page transactions) in the same manner.

The Web transaction probe plays back the information defined in the Web transaction file according to the measurement condition. A specified URL's response is checked according to the response determination information defined in the Web transaction file. Any measurement that does not meet the condition results is a measurement failure. The checking based on the response determination information is applicable only when the response acquired from the specified URL is in HTML format (Content-Type is text/html). If the received data is compressed, the response check results in a measurement failure. This checking is not performed for acquisition of embedded resources.

The following describes and provides notes on a Web transaction operating environment.

HTTP Version

HTTP/1.0 is applicable.

Referer Header

The Web transaction probe does not issue the requests with the Referer Header.

RFC compliance

For the functions that are not compliance with RFCs and the restrictions, see the above notes.

HTTP(S) processing sequence

For details about a sequence of HTTP(S) communication processing performed in a Web transaction, see HTTP (PI_HTP) and HTTPS (PI_HTPS) in this chapter.
