Configuring access to SMF data for IT Operational Analytics
IT Operational Analytics (ITOA) allows you to retrieve, analyze, and report data for IT operations. System information can be logged using the IBM System Management Facility (SMF) and the native Data Service server logging feature. Logging allows you to collect various system and operations-related information.
Before you begin
IBM APAR OA49263 provides real-time SMF support and is a requirement for the configuration of real-time SMF. APAR OA48933 is required to address accessing logstreams. SMF logstreams configuration is required for in-memory resource support.
About this task
Virtual tables for SMF are provided in the hlq.SAZKSMAP data set.
- Data set mode - SMF information is recorded in MANx data sets. When a data set gets full, the data is processed via IFASMFDP. When defining global variables for SMF in data set mode the output of IFASMFDP is used.
- Logstream mode - SMF information is recorded in multiple logstreams and data can be read directly from the logstreams. Logstream recording is determined by the data set name beginning with IFASMF that is used in the VTB rule for SMF.
- In-memory (real-time) mode - SMF information is read directly from the system buffer. SMF information is read in real-time.
When defining the global variables for SMF the data set can be either a logstream or a SMF dump data set from IFASMFDP. The logstream data set is recommended for access to near real-time data.
To configure IT Operational Analytics, complete the tasks that follow.
