Description
mdump displays event bank contents (online or offline).
This application allows the experimenter to "peep" into the data flow in order to display a snap-shot of the event. Its use is particularly powerful during experimental setup. In addition mdump has the capability to operate on data save-set files stored on disk or tape. The main restriction is the fact that mdump works only for events formatted in banks (i.e. MIDAS banks - see MIDAS Event Structure).
mdump can be built with zlib.a in order to gain direct access to the data within a file with extension mid.gz or ybs.gz. See Building Option NEED_ZLIB.
Arguments for Online use
[-h ] : help for online use.
mdump for online
-l # : display # events (look 1)
-f format (auto): data representation ([x]/[d]/[a]scii) def:bank header content
-w time : insert wait in [sec] between each display
-m mode : Display mode either Bank or raw
-j : Display # of banks and bank name list only for all the event
-b bank name : search for bank name (case sensitive)
-i evt_id (any) : event id from the FE
-k mask (any) : trigger_mask from FE setting
-g type : sampling mode either SOME or all)
-s : report buffer data rate and fill level
-s -d : for use with -s: also report all buffer clients and requests
-t type (auto) : Bank format (Midas)
-x Source : Data source selection def:online (see -x -h)
-y : Serial number consistency check
>>> in case of -y it is recommended to used -g all
-z buffer name : Midas buffer name default:[SYSTEM]
[-h Hostname] [-e Experiment]
Arguments for Offline use
[-x -h] : help of offline use.
mdump for replay
-x file name : file to inspect
-m mode : Display mode either Bank or raw
-b bank name : search for bank name (case sensitive)
-i evt_id (any) : event id from the FE
-[single] : Request single bank only (to be used with -b)
-y : Serial number consistency check
-j : Display # of banks and bank name list only for all the event
-k mask (any) : trigger_mask from FE setting
>>> -i and -k are valid for YBOS ONLY if EVID bank is present in the event
-w what : [h]eader, [r]ecord, [l]ength
[e]vent, [j]bank_list (same as -j)
>>> Header & Record are not supported for MIDAS as no physical record structure exists
-f format (auto): data representation ([x]/[d]/[a]scii) def:bank header content
-r # : skip event(MIDAS) to #
Usage
mdump can operate on either data stream (online) or on save-set data files. Specific help is available for each mode.
> mdump -h > mdump -x -h
