Change the Apache default server properties

This task describes how to modify the Apache default server properties that are defined in the monitor configuration file.

  1. Open the apache.cfg file in the <LoadRunner Enterprise server root folder>\dat\monitors directory.

  2. Edit the following parameters after the Delimiter=: statement:


    Server statistics information URL.


    Server port number.


    Rate (milliseconds) at which the monitor polls the server for the statistics information. If this value is greater than 1000, LoadRunner Enterprise uses it as its sampling rate. Otherwise, it uses the sampling rate defined in the Monitors tab of the Options dialog box.
