(ZOS) SMF Subtype 10: Outbound Request record
The purpose of the Outbound Request SMF record is to record requests that go outbound. This record is produced whenever an optimized local adapter request goes outbound.
Use the SMF Subtype 10 record to monitor how many outbound requests are occurring, where they are going and how long it takes.
We can activate this record through the administrative console by setting server_SMF_outbound_enabled=1 (or server_SMF_outbound_enabled=true).
If we do not want these records to be generated, we can set server_SMF_outbound_enabled=0 (or server_SMF_outbound_enabled=false), which turns off the creation of this SMF record type. This is the default value for this property.
Outbound Request record schema
The record header is the same for every Subtype 10 record created by the same server.
The Outbound Request record is divided into the following sections.
