Program name: CLBSwissKnife.

General description: This program aims to provide a powerful debugging tool for all the kind of data sent by a KM3NeT DOM.

It listens to the specified UDP port and prints out to the screen some informations contained in the read CLB datagrams.

Since version 5.0, it operates in two main modes:

• in UDP mode (available since the first release), the program reads data directly from a UDP port. In this mode it is allowed to perform several tasks, such as read all kind of data, dump data on file and send monitoring data to a RoyWeb server;
• in Ligier mode, data are retrieved from a Ligier subscription. Only monitoring data are available and no secondary tasks are allowed.

General options: The program is configured via command line parameters. UDP mode is default and can be forced with the -u/–udp command line switch. Ligier mode can be activated with the -l/–ligier switch.

In the systems where the ncurses libraries are present, is possible to use the -g/–gui option to display multiple DOMs data via a text gui, in conjunction of the UDP-mode "-m/--monitoring" option or in the Ligier mode. Press the 'h' key to see the help for GUI mode. Arroy keys can be used to select a dom and to scroll the list.

With the "--map" option the user can specify a map file to be used to match the DOM IDs of incoming data. The DOM map file is an ASCII file reporting assignments of DOM IDs or MAC addresses with names. Each assignment must be separated by a semicolon. An example of map file follows:

08:00:30:BE:B7:A2 = CLB19; 817805038 = CLB13;

By default, CLBSwissKnife will try to load the file

~/.doms.csk

as a map file. The user can write the information about its setup to this file and let CLBSK use it without specifying any "--map" option.

Use: $ CLBSwissKnife -h for a detailed help and $ CLBSwissKnife -v for version information.

UDP-mode options: The user can specify the port to bind and/or the data type:

• if the port is specified using the "-p" or "--port" options the type is automatically determined as data comes;
• if the port is specified using one of the other options ("-o/--optical", "-a/--acoustic", "-m/--monitoring"), the program is forced to parse the incoming data with the specified data type; with these options it is not mandatory to specify a port number, since a default value is pre-defined.

With the "-f/--dump-file" option is also possible to specify a destination file in which the incoming data will be stored for offline analysis.

In the monitoring-mode, with the "-r/--royweb" option it is possible to send the hit rates to a ROyWeb server. This option accept 3 parameters separated by a colon character (":"), which are:

• the format of the name of the ROy parameter; the format string allows the use of the following place-holders:
  • "%d": DOM ID
  • "%n": DOM name as in the map file (see below); if not present the DOM ID is used.
  • "%c": channel ID (0-30)
• the ROyWeb server address
• the ROyWeb server port

Es: CLBSwissKnife -m -r HitRates-DOMd-CHc:localhost:9999

A default HR_n.c:localhost:9999 is used, otherwise all three parameters must be set at once.

Moreover, the time difference between two consecutive monitoring packets is sent to the ROy server with the tag "Time_difference". This is useful in order to highlight possible packet losses when a single CLB is used.

Ligier-mode options: The Ligier mode allows the user to monitor CLB data using a Ligier connection. To be activated a "-l/--ligier" flag must be present in the command line.

Ligier endpoint can be set with "-s/--server", while the tag can be set with the "-t/--tag". Proper default values are available and are listed in the on-line help.
