    NAME
        xentrace_format - pretty-print Xen trace data
    
    SYNOPSIS
        xentrace_format [ DEFS-FILE ]
    
    DESCRIPTION
        xentrace_format parses trace data in xentrace binary format from standard
        input and reformats it according to the rules in a file of definitions
        (DEFS-FILE), printing to standard output.
    
        The rules in DEFS-FILE should have the format shown below:
    
        event_id whitespace format
    
        Each rule should start on a new line.
    
        The format string may include format specifiers, such as: %(cpu)d,
        %(tsc)d, %(event)d, %(1)d, %(2)d, %(3)d, %(4)d, %(5)d
    
        [ the `d' format specifier output in decimal, alternatively `x' will
        output in hexadecimal and `o' will output in octal ]
    
        These correspond to the CPU number, event ID, timestamp counter and the 5
        data fields from the trace record. There should be one such rule for each
        type of event to be pretty-printed (events which do not have formatting
        rules are ignored).
    
        A sample format file for Xen's predefined trace events is available in the
        file tools/xentrace/formats in the Xen source tree.
    
        Depending on your system and the rate at which trace data is produced,
        this script may not be able to keep up with the output of xentrace if it
        is piped directly. In these circumstances you should have xentrace output
        to a file for processing off-line.
