# Script for graphical representation of VSPERF results
#
# Usage:
# ./create_graph ["test names" [filter [directory]]]
#
# where:
# "test names" is a !!! quoted !!! string with vsperf testcase names separated
# by spaces
# Default value: "phy2phy_tput"
#
# "filter" is used to select matching VSPERF results; Its value
# will be used as PATTERN of grep command executed on selected
# csv result files.
# Default value: ",OvsDpdkVhost,"
#
# "directory" is a directory name, where vsperf results (i.e. results_*
# subdirectories) are located
# Default value: "/tmp"
#
# Example of invocation:
# ./create_graph "phy2phy_tput phy2phy_cont pvp_cont pvvp_cont" ",OvsVanilla,"
TESTS="phy2phy_tput" # default set of TCs to be plotted
FILTER=",OvsDpdkVhost," # default filter to be applied on matching CSV files
