and database(s) is one of these:
• [database ... ] (for caliper report)
• [database1 database2 ... ] (for caliper merge)
• database2 database1 (for caliper diff)
Using the caliper report Command to Create a Report from One or More Databases
Use caliper report to create a single output report from one or more databases.
The syntax for this command is:
caliper report [report_options] [database ...]
You can specify multiple databases, either individually or by using wildcards. For example, to
generate a report for all databases matching dbase.* to the text file out.txt, do the following:
$ caliper report -o out.txt dbase.*
If you do not specify a database, HP Caliper uses the database created from your latest run.
By default, data is merged for matching processes in the same collection run. See “--group-by”
(page 61).
Using the caliper merge Command to Merge Data From Multiple Collection Runs
Use caliper merge to merge data from two or more databases to a single output report. In the
report, the contributing collection runs are appended one after another.
The syntax for this command is:
caliper merge [report_options] [database1 database2 ...]
HP Caliper will produce a report for all databases (for all collection runs and all processes) specified
on the command line. Data will be merged for all matching processes, even if they are in different
collection runs. See Example 2.
