Options

dumpcalls [ --help ] [ --version ] [ --extcap-interfaces ] [ --extcap-dlts ] [ --extcap-interface=<interface> ] [ --extcap-config ] [ --extcap-capture-filter=<capture filter> ] [ --capture ] [ --fifo=<path to file or pipe> ] [ --log-level=<log level> ] [ --log-file=<path to file> ] [ --include-capture-processes=<TRUE or FALSE> ] [ --include-switch-calls=<TRUE or FALSE> ]

## DESCRIPTION

dumpcalls is an extcap tool that allows one to capture system calls on a Linux system.

## OPTIONS

--help

--version

  Print the program version.

--extcap-interfaces

  List the available interfaces.

--extcap-interface=<interface>

  Use the specified interface.

--extcap-dlts

  List the DLTs of the specified interface.

--extcap-config

  List the configuration options of specified interface.

--extcap-capture-filter=<capture filter>

  The capture filter. Must be a valid Sysdig / Falco filter.

--capture

  Start capturing from the source specified by --plugin-source via the specified interface and write raw packet data to the location specified by --fifo.

--fifo=<path to file or pipe>

  Save captured packet to file or send it through pipe.

--log-level

  Set the log level

--log-file

  Set a log file to log messages in addition to the console

--include-capture-processes

--include-switch-calls

  Include "switch" calls if TRUE. Defaults to FALSE.

## EXAMPLES

To see program arguments:

    dumpcalls --help

To see program version:

    dumpcalls --version

To see interfaces:

    dumpcalls --extcap-interfaces

Only one interface (dumpcalls) is supported.

Example output

    interface {value=dumpcalls}{display=Falco plugin}

To see interface DLTs:

    dumpcalls --extcap-interface=cloudtrail --extcap-dlts

Example output

    dlt {number=147}{name=cloudtrail}{display=USER0}

To see interface configuration options:

    dumpcalls --extcap-interface=cloudtrail --extcap-config

Example output

    arg {number=0}{call=--plugin-source}{display=Plugin source}{type=string}{tooltip=The plugin data source. This us usually a URL.}{placeholder=Enter a source URL…}{required=true}{group=Capture}
    arg {number=1}{call=cloudtrail-s3downloadconcurrency}{display=s3DownloadConcurrency}{type=integer}{default=1}{tooltip=Controls the number of background goroutines used to download S3 files (Default: 1)}{group=Capture}
    arg {number=2}{call=cloudtrail-sqsdelete}{display=sqsDelete}{type=boolean}{default=true}{tooltip=If true then the plugin will delete sqs messages from the queue immediately after receiving them (Default: true)}{group=Capture}
    arg {number=3}{call=cloudtrail-useasync}{display=useAsync}{type=boolean}{default=true}{tooltip=If true then async extraction optimization is enabled (Default: true)}{group=Capture}

To capture AWS CloudTrail events from an S3 bucket:

    dumpcalls --extcap-interface=cloudtrail --fifo=/tmp/cloudtrail.pcap --plugin-source=s3://aws-cloudtrail-logs.../CloudTrail/us-east-2/... --capture

or:

    dumpcalls --capture --extcap-interface cloudtrail --fifo ~/cloudtrail.pcap --plugin-source s3://my-cloudtrail-bucket/AWSLogs/o-abc12345/123456789012/ --cloudtrail-s3downloadconcurrency 32 --cloudtrail-s3interval 5d-2d --cloudtrail-aws-region eu-west-1

Note | `CTRL`+`C` should be used to stop the capture in order to ensure clean termination.
