## EXAMPLES

To see program arguments:

    etwdump --help

To see program version:

    etwdump --version

    etwdump --extcap-interfaces

Example output

    interface {value=etwdump}{display=ETW reader}

To see interface DLTs:

    etwdump --extcap-interface=etwdump --extcap-dlts

Example output

    dlt {number=1}{name=etwdump}{display=DLT_ETW}

To see interface configuration options:

    etwdump --extcap-interface=etwdump --extcap-config

Example output

    arg {number=0}{call=--etlfile}{display=etl file}{type=fileselect}{tooltip=Select etl file to display in Wireshark}{group=Capture}
    arg {number=1}{call=--params}{display=filter parameters}{type=string}{tooltip=Input providers, keyword and level filters for the etl file and live session}{group=Capture}
    arg {number=2}{call=--iue}{display=Should undecidable events be included}{type=boolflag}{default=false}{tooltip=Choose if the undecidable event is included}{group=Capture}

To capture:

    etwdump --extcap-interface etwdump --fifo=/tmp/etw.pcapng --capture --params "--p=Microsoft-Windows-Wmbclass-Opn --p=Microsoft-Windows-wmbclass --k=0xff --l=4"
    etwdump --extcap-interface etwdump --fifo=/tmp/etw.pcapng --capture --params "--p=Microsoft-Windows-Wmbclass-Opn --p=Microsoft-Windows-NDIS-PacketCapture"
