FLOWD(8)               DragonFly System Manager's Manual              FLOWD(8)

NAME
     flowd - NetFlow collector daemon

SYNOPSIS
     flowd [-hdg] [-D macro=value] [-f config_file] command

DESCRIPTION
     flowd is a small NetFlow collector daemon capable of understanding Cisco
     NetFlow version 1, version 5 and version 9 packet formats.  flowd
     supports filtering and tagging of received flows before they are stored
     on disk, using a filter syntax similar to the OpenBSD PF packet filter.
     The on-disk format is flexible in that it allows selection of which
     packet fields are recorded, so logs may be made very compact.

     By default, flowd will obtain its configuration from the flowd.conf(5)
     file, which typically resides in /usr/local/etc/flowd.conf.  However, a
     different configuration file may be specified on the commandline using
     the -d option.

     flowd may be terminated by sending it a SIGTERM signal.  Upon receipt of
     a SIGUSR1 flowd will close and reopen its logfile.  This is useful for
     rotating logs.  When flowd receives a SIGHUP it will re-read its
     configuration and re-open its logfile.  Some basic runtime statistics
     will be logged when flowd is signalled with SIGUSR2 or SIGINFO.

     The command-line options are as follows:

     -D macro=value
             defines the name macro, which can then be used later in the
             config file.  Refer to the MACROS section in flowd.conf(5) for
             more information on the use of macros.

     -d      Places flowd in debugging mode.  In this mode, flowd will not
             fork to the background and will print verbose diagnostics,
             including details of each flow received.

     -g      Causes flowd not to fork and background itself.  Logging will be
             reported to stderr instead of syslog.

     -f config_file
             Specify an alternate location for the configuration file Default
             is /usr/local/etc/flowd.conf

     -h      Displays commandline usage information.
