Specifies the path map to use for finding source files used for reporting source statements.
Applies to any PMU histogram report, which is the only kind of report that references source code.
Path map entries are separated by a colon (:) and applied in order until HP Caliper finds a file match.
•Simple entries are prepended to file names.
•You can provide substitute paths by using
•Perl regular expressions are allowed in the left half of a substitution.
As of Caliper 5.2, the kernel unwinding is turned on by default in cstack measurement. When HP Caliper is run as root, the cstack measurement now records and reports both user and kernel space portions of the call stack.
The
The default kernel stop functions are specified in the cstack configuration file. They are - real_sleep, sleep_pc, sleep, ksleep, sleep_one, ksleep_one, swtch, swtch_to_thread, sleep_park.
Specifies cutoff values that limit the functions reported in the Function Summary section of a PMU histogram report. This option is used in conjunction with the
HP Caliper stops reporting information when it reaches either a percentage cutoff or a cumulative percentage cutoff:
•You can limit the report only to functions that exceed a specified percentage of the total for the sorting/cutoff metric. Once HP Caliper encounters this percentage cutoff, it stops reporting functions.
•You can limit the report by having HP Caliper stop reporting functions once the cumulative percent of the functions so far listed exceeds the cumulative percentage cutoff value.
You can also specify an integer for the minimum number of functions to be displayed for all load modules.
percent_cutoff | The percentage of the total for the sort metric that a given function |
| must exceed to appear on the report. |
| Default value is 0.1. |
| This value only takes effect if the |
| for the report. |
cum_percent_cutoff | The value of the cumulative percentage at which HP Caliper stops |
| reporting results. |
| Default value is 100. |
