# To use this script you will need to have exported data using the
|
|
# export-to-postgresql.py script. Refer to that script for details.
|
|
#
|
|
# Following on from the example in the export-to-postgresql.py script, a
|
|
# call-graph can be displayed for the pt_example database like this:
|
|
#
|
|
# python tools/perf/scripts/python/call-graph-from-postgresql.py pt_example
|
|
#
|
|
# Note this script supports connecting to remote databases by setting hostname,
|
|
# port, username, password, and dbname e.g.
|
|
#
|
|
# python tools/perf/scripts/python/call-graph-from-postgresql.py "hostname=myhost username=myuser password=mypassword dbname=pt_example"
|
|
#
|
|
# The result is a GUI window with a tree representing a context-sensitive
|
|
# call-graph. Expanding a couple of levels of the tree and adjusting column
|
|
# widths to suit will display something like:
|
|
#
|
|
# Call Graph: pt_example
|
|
# Call Path Object Count Time(ns) Time(%) Branch Count Branch Count(%)
