HP Caliper 5.3 Quick Start
Updated: September 2012
http://www.hp.com/go/caliper
HP Caliper commands have the following forms:$ caliper measurement [opts] app [app_args] $ caliper measurement [opts] PID [PID2 …] $ caliper measurement [opts]
where: | specifies what type of data to collect |
measurement | |
opts | are HP Caliper options in these forms: |
| |
app | is a program to invoke and measure |
app_args | are the arguments to app |
PID | is ID of a process to attach to and measure |
collects data | |
DB | is a database to report or analyze |
report | creates a report from DB(s) |
merge | creates a report from merged DBs |
diff | creates a report from differenced DBs |
advise | generates performance tuning advice |
info | generates help information |
Measurements (measurement argument)
alat | ALAT miss profile |
branch | branch prediction profile |
cpu | CPU event metrics |
cstack | sampled call stack profile |
cycles | flat profile of IPs |
{di}cache | |
data or instruction cache misses | |
{di}tlb | data or instruction TLB misses |
ecount | counts of specific CPU events |
fprof | flat profile of function CPU time |
overview | enables collecting fprof, cstack |
| and dcache data in one single |
scgprof | collection run |
sampled call graph profile | |
traps | traps, interrupts, and faults |
|
Using the Graphical User Interface
$ caliperstart GUI to interactively set collection specification, initiate measurement runs, and graphically explore performance
Choosing Target of Data Collection
specific processes (default) | |
(short form of above) | |
all processes on system |
Generating Reports
write text report to out.txt | |
write CSV report to out.csv |
Collecting System Usage Data
(for any measurement; not available on Linux)Choosing Specific Processes to Measure
root process and all descendants | |
(the default) | |
root (initial) process only | |
root process and forked children | |
processes whose executable’s | |
base name is name | |
processes whose argv[0] is | |
name | |
processes whose argv[1] is | |
name | |
processes created by exec() | |
| whose executable file is name |
| processes created by vfork() |
| and exec() whose executable file |
is name | |
processes whose executable name |
processes whose executable name matches name1 or name2, both of which may contain shell wildcards
processes whose executable name starts with ‘foo’, but do not collect data on foobar or its descendants
processes whose executable name starts with ‘foo’; potentially profile descendants of, but do not collect data on, foobar
Changing Sampling Parameters
(for measurements that use sampling)sample every 50,000 events | |
sample every 50,000 events, | |
| varying the event count by |
1000 | |
use default number of events, | |
varying the event count by 5% | |
use default event count and | |
| variation; use CPU_CYCLES |
as the sampling event | |
sample every 5000 | |
| CPU_CYCLES (abbr. CC) using |
| default variation |
Grouping Data
Reporting from a Database
$ caliper measurement [opts]Merging or Differencing Data from Multiple Runs
$ caliper mergemerge data collected in database dbName with the last data recorded in .hp_caliper_databases; write CSV output to directory dir
$ caliper diffGetting Help
$ man caliper man page with full descriptions $ caliper info
| list event name and/or all |
| events whose name contains |
name | |
print short help text | |
print long help text | |
append help to report |
