Tuning Performance › Record CPU Usage › How You Implement NCL CPU-time Accounting › Generation of SMF Records

Generation of SMF Records

SMF records are generated under the following circumstances:

• If the amount of CPU-time used by the user since the last record was generated, surpasses a predefined threshold
• On system initialization if user NCL CPU-time accounting is active at the time of shutdown

Whenever an SMF record is generated for a user, their CPU-time is reset to zero. Each SMF record contains the amount of CPU-time used by the user since the previous SMF record was generated.
