Procedure
-
Identify the user ID where the IBM HTTP Server runs.
Grant read authority to the BPX.SMF facility of the appropriate user ID.
-
Verify that the
mod_mpmstats and mod_status modules are
loaded into the server.
-
Enable the
ExtendedStatus directive.
The ExtendedStatus directive is set to on by default.
-
Set the
SMFReportInterval directive to the number of seconds between
reports.
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.
-
Enable the recording of SMF type 103 subtype 13 records by editing the
SMFPRMxx parmlib member.
