z/OS transactional workloads contain interactions between IBM z/OS components,
middleware, Independent Software Vendor (ISV) products, client applications and
shared resources. Sometimes these interactions and resources can cause transient
short term performance issues. In the worst cases, these transient issues can
repeat, worsen, and result in broader service degradation, critical situations,
and even outages. When things go wrong, Subject Matter Experts spend significant
time (e.g. days, weeks, or months depending on the issue) looking for clues
needed to define the root cause. SMF 98 and 100 records can be generated on
synchronized, 5-second intervals with micro-summary, exceptionalism enriched
data. Subject Matter Experts can analyze this data to identify and correlate
short interval anomalies with only 15 minutes of data, reducing the time
required to diagnose complex critical situations, service degradation, and
outages. In addition, Subject Matter Experts can proactively identify repeating
transient workload resilience risks, providing an opportunity to diagnose the
root cause and address it before a crit-sit or outage occurs.
