This section provides information on the Timestamp directives for the Page Detailer client. This information includes specific directive syntax, scopes, defaults and values. Links to related topics appear at the end of this section.
Page Detailer is a client that allows you to measure the time taken for the server to process requests. This client displays the amount of time it takes for the server to receive a request and the amount of time it takes from the client request, until the receipt of the reply. The Page Detailer client is included in WebSphere Studio Advanced Edition and in WebSphere Commerce Suite. See the WebSphere Studio Web page and the WebSphere Commerce Suite Web page for more information.
Page Detailer records many measurements, including the following:
The headerts module enables Page Detailer to obtain timing data from the server. This data in turn provides more data accuracy. This module records the timestamp upon receipt of a request from a client and stores it in an Apache table used to track URLs, so you can insert a TS- macro into the reply header. When the reply header is prepared, it retrieves the original timestamp, gets a new timestamp, calculates the duration between the new and the original timestamp and then adds the information to the formatted reply header line.
Following is an example of the TS- macro, or formatted reply header line, in the reply header:
The TS-APACHE prefix is appended to the server identity found in the Timestampid directive followed by a colon, then the time of day and finally the duration at the server.
Look for the following Timestamp directives in the httpd.conf file:
