queues Provides bus request queue (BRQ) metrics that may give some insight into
possible performance problems related to the system bus.
stall Provides metrics on primary CPU performance limiters by breaking the CPI
into seven components.
sysbus Provides metrics on system bus utilization. If you specify the sysbus event
set, you must use the --bus-speed option to provide bus speed in MHz.
For example: --bus-speed 200.
threadswitch Provides data about the effect of HyperThreading on the measured processes
for Integrity servers dual-core Itanium 2 and Itanium 9300 quad-core processor
systems.
tlb Provides metrics related to translation lookaside buffer (TLB) misses.
cstack Measurement Report Description
With the cstack measurement, produced by the cstack measurement configuration file, HP Caliper
measures and reports a sampled call stack profile, produced by periodically sampling the
application program counter and each of its thread's call stacks. It also measures and reports the
blocking primitives that are responsible for the blocked samples.
Example Command Line for Text Report
$ /opt/caliper/bin/caliper cstack -o results.txt ehh_thr_mutex1
Example Command Line for CSV Report
$ caliper cstack --csv results.csv enh_thr_mutex1
cstack Measurement Report Metrics
Table 16 (page 184) shows the information found in the flat profile part of a Call Stack Profile
report.
In this table, “program object” refers to any of the following:
• Process summary
• Load module
• Function
• Source statement
• Instruction bundle
