FLOWD-READER(8) 	     System Manager's Manual		 FLOWD-READER(8)

NAME
     flowd-reader -- Read, filter and concatenate binary flowd logfiles

SYNOPSIS
     flowd-reader [-LUvqd] [-H num_flows] [-f filter_file] [-o output_file]
		  flow_log [flow_log] [...]

DESCRIPTION
     flowd-reader  is  a program to read, filter and/or concatenate flowd(8) bi-
     nary log files.

     If only flow_log arguments are specified, flowd-reader will  read	each  of
     the log files and print their contents to standard output.

     Filtering may be performed by specifying a filter_file using the -f option.
     In this mode, flowd-reader will filter the flows it reads from the flow_log
     file(s) before printing them.

     Finally,  the  -o	option may be used to specify a output_path to which all
     the flows that have been read and passed any filters are written.

     The command-line options are as follows:

     -H num_flows
	     head(1) mode.  Read only the first num_flows of the file.

     -L      Allows flowd-reader to read legacy version 2 flow	logs  (generated
	     by  flowd(8)  versions prior to v9.0).  This may be used to convert
	     old flow logs to the newer form.

     -U      Causes flowd-reader to report all timestamps in UTC rather than the
	     local timezone.

     -d      Display debugging	information,  including  the  number  of  filter
	     matches if one has been specified.

     -f filter_file
	     Specify  a  filter_file.	containing filtering and field selection
	     rules to apply to the flows that are loaded.  These rules may  con-
	     tain  store  directives  and  filter  rules  as  described  in  the
	     flowd.conf(5) manual (under the Storage field selection and  Filter
	     sections  respectively.)	Any other directives are ignored.  If no
	     store directives are specified in the filter_file then the  default
	     is to preserve all the fields in the input flow logs.

     -q      Operate  quietly.	If  this argment is specified, flowd-reader will
	     not display the flows it is processing.  This may be useful in con-
	     junction with the -f option.

     -o output_file
	     Specify an output_file to which all flows that have been  read  and
	     have  passed any filters are written.  The flows are written in the
	     flowd binary log format.  This option is useful when  filtering  or
	     concatenating flow log files.

     -v      Reports  all  information	in the flow log, rather than the default
	     brief subset.

     -h      Displays commandline usage information.
