Configuring IBM HTTP Server for SMF recording

Use System Management Facilities (SMF) to record operational statistics for IBM® HTTP Server.

About this task

You can enable the recording of SMF type 103 subtype 13 records for IBM HTTP Server after you load the appropriate modules, set the appropriate directives, and update the SMFPRMxx parmlib member.

Procedure

  1. Identify the user ID that the IBM HTTP Server is to run under. Grant read authority to the BPX.SMF facility of the appropriate user ID.
  2. Verify that the mod_mpmstats and mod_status modules are loaded into the server.
  3. Enable the ExtendedStatus directive.

    The ExtendedStatus directive is set to on by default.

  4. Set the SMFReportInterval directive to the number of seconds between reports.

    For example,

     SMFReportInterval 600

    If the server is not idle, the server writes records every interval. The default is 0. When the value for the directive is 0, no SMF records are written.

  5. Enable the recording of SMF type 103 subtype 13 records by editing the SMFPRMxx parmlib member.
