Abstract
When a transient performance problem is impacting your system, traditional SMF data captured on the SMF interval (e.g. 15 or 30 minutes) may not help determine the underlying root cause. IBM z/OS Workload Interaction Correlator SMF records often contain valuable data for diagnosing transient performance problems; summary activities with a worst offender and its activity every 5 seconds. IBM benchmarks cannot detect any additional CPU cost from collecting all available Correlator SMF records. IBM encourages customers to collect and archive all available Correlator SMF records with their other SMF data (e.g. SMF 70s, 72s, 113s, etc) to ensure first failure data capture for performance problems.
This White Paper discusses the data collection Best Practices for IBM z/OS Workload Interaction Correlator records. Authored by Dan Rosa.
