HP Caliper User's Guide

Change the application code and/or build options and start over at step 1 with
the revised application and a new set of performance measurements and
databases.
or:
•
• Make new performance measurements in step 2, saving the data to a new
database, and rerun the Advisor.
5. Continue making adjustments as long as you keep receiving meaningful data.
Command Line to Invoke the Advisor
The command line is:
$ caliper advise [advise_options] [database_list]
where advise_options are:
--advice-classes [all]|[[general][:cpu][:memory][:io][:system]]
--advice-cutoff min-index[,min-count[,max-count]]
--advice-details [all]|[[description][:improvement][:measurement]
[:explanation][:rule]]
--analysis-focus [executable:]name|all[,[executable:]name],...
–o outputfile[,append|create]
--rule-files rulefile1[,rulefile2,...]
For these options:
--advice-classes Specifies which classes of advice are printed. It can be all
or any combination of general, cpu, memory, io, or
system, separated by colons (:).
The default is all.
--advice-cutoff
Specifies how much of the advice to print. All advice is sorted
by its index value (the greater the index, the greater the
importance). min-index specifies the lowest index value of
advice to print. min-count gives the minimum number of
advice items to print while max-count gives the maximum
number. min-count takes precedence over min-index, so
if only a few pieces of advice apply, some with an index less
than min-index might be printed.
The defaults are 5.0 for min-index, 5 for min-count, and
15 for max-count.
--advice-details
Specifies what portions of advice messages are printed. It
can be all or any combination of description,
improvement, measurement, explanation, or rule,
