# This command can be used to
|
|
# 1. Enable/Disbale the subroutine calling trace.
|
|
# 2. Enable the commented trace log inside a subroutine.

# The example of -c
|
|
# (daemonize,do_installm_service,do_udp_service)|xCAT::Utils(isMN,Version)|xCAT_plugin::DBobjectdefs(defls,process_request)
|
|
# If specifying a file
|
|
# (daemonize,do_installm_service,do_udp_service)
|
|
# xCAT::Utils(isMN,Version)
|
|
# xCAT_plugin::DBobjectdefs(defls,process_request)

# Following three lines need to be added to enable the capability of commented trace
|
|
#if (defined $ENV{ENABLE_TRACE_CODE}) {
|
|
# use xCAT::Enabletrace qw(loadtrace filter);
|
|
# loadtrace();
|

#The commented trace can be two formats:
|
|
#1. trace section
|
|
# ## TRACE_BEGIN
|
|
# # print "In the debug\n";
|
|
# ## TRACE_END
|
|
#2. trace in single line
|
|
# ## TRACE_LINE print "In the trace line\n";
