Logstream Recording

Use logstream recording of SMF data with z/OS 1.9 or later.

Business Value:

Logstream recording of SMF data eliminates loss of data that can occur at switch time due to buffer overflows when using the traditional MAN file recording technique. This is especially true for large data centers with a high volume of SMF recording.

When using logstream recording, CA SMF Director can:

• Dynamically manage the data being dumped to the history files
• Eliminate the requirement of manually setting start and end timestamps
• Support coupling facility and DASD only logstreams
• Support coupling facility logstreams with data from multiple systems

Additional Considerations:

You can switch between logstream recording and MAN file recoding and CA SMF Director ensures that all of the SMF records are processed and archived.

You can filter SMF data based on MAN files or logstreams using:

• EXTRACT and PRINT control statements
• History file listings using LISTH statement
