HP Caliper Linux Release Notes

NOTE: : When collecting data, be sure to use the command line's –db-save
option or the GUI Collect view's Measurement Storage options (see Measurement
tab) if you wish to save symbols, code, and line tables for off-line viewing.
• The dcache measurement now shows dcache misses caused by RSE activity.
• A new system usage viewer provides application-wide or system-wide views of
process run states, I/O activity, and system calls, with the capability of easily
drilling down to view system usage for the hottest processes and threads.
• The main tool bar now has an Interrupt button that allows you to interrupt GUI
activties that appear stuck or are taking too much time.
• When function names are wider than the available column width in tables, or node
width in graphs, the function name is now truncated on the left and right to display
the most meaningful part of the function name. This is particularly useful for long
C++ functions names and function names with a long load module prefix. The full
function name is always available in tool tips.
• By default, the GUI now shows thousands separators (comas) in numeric data.
This feature can be disabled via the Preference Dialog.
Changes for Version 4.4
New Options and Enhancements to Options
• The new option: --db-save=[syms][:code][:src] allows you to save in the
database containing your measurements, additional information helpful in later
reporting. This option must be used when the measurement is first made. You can
then generate reports or view reports in the GUI without needing access to the
system where data was collected. You can save symbols ("syms", for function
names), "code" (for disassembly), and/or line tables ("src" for source line lookup)
to a Caliper database.
• cstack measurements have been enhanced to report blocking primitives (mutexes,
rwlocks, and condition variables).
• Per-thread data collection and reporting are now the measurement default. To
report only data summed per process across its threads, specify --thread all.
• per-thread reports have been enhanced to show thread start funcion names as
part of thread IDs in the following format:
<thread-id>@thread-start-function.
• You can now control how many call stacks are reported in the “Hot Call Paths”
section of cstack reports using the new option, --callpath-cutoff.
• Database compatibility has been improved. HP Caliper 4.4 can read (but not write)
version 4.3 databases. From this release on, HP Caliper will be able to read
databases from version 4.3 and higher.
