3 @brief Capture session start / finish times and request details
4 @details For details, see
5 https://rawsas.com/event-logging-of-stored-process-server-sessions.
6 Requires a base table in the following structure (name can be changed):
7
8 proc sql;
9 create table &libds(
10 request_dttm num not null format=datetime.
11 ,status_cd char(4) not null
12 ,_metaperson varchar(100) not null
13 ,_program varchar(500)
14 ,sysuserid varchar(50)
15 ,sysjobid varchar(12)
16 ,_sessionid varchar(50)
17 );
18
19 Called via STP init / term events (configurable in SMC) as follows:
20
21 %mp_stprequests(status_cd=INIT, libds=YOURLIB.DATASET )
22
23
24 @param status_cd= Use INIT for INIT and TERM for TERM events
25 @param libds= Location of base table (library.dataset). To minimise risk
26 of table locks, we HIGHLY recommend using a database (NOT a SAS dataset).
27 THE LIBRARY SHOULD BE ASSIGNED ALREADY - eg in autoexec or earlier in the
28 init program proper.
