cycles Measurement Report Description
Available only on Integrity servers
With the cycles measurement, produced by the cycles measurement configuration file, HP Caliper measures and reports a flat profile of the instruction pointers (IPs). This measurement uses the
The flat profile is produced by statistical sampling of the execution trace buffer (ETB) configured to capture IPs of retired intructions. The cycles measurement samples the ETB at a regular interval, for example, at every N CPU cycles. This provides a statistical identification of where CPU events are occurring.
