NAME
       flow-stat -- Generate reports with flow data.

SYNOPSIS
       flow-stat [-hnpPw]  [-d debug_level]  [-f format]  [-S sort_field]  [-s
       sort_field]  [-t	tally_lines]  [-T title]

DESCRIPTION
       The flow-stat utility generates usage reports for flow data sets	by  IP
       address,	 IP  address  pairs,  ports,  packets, bytes, interfaces, next
       hops, autonomous	systems, ToS bits, exporters, and tags.

OPTIONS
       -d debug_level
		 Enable	debugging.

       -f format

       Report format.  Choose from the following:

	   0  Overall Summary
	   1  Average packet size distribution
	   2  Packets per flow distribution
	   3  Octets per flow distribution
	   4  Bandwidth	per flow distribution
	   5  UDP/TCP destination port
	   6  UDP/TCP source port
	   7  UDP/TCP port
	   8  Destination IP
	   9  Source IP
	   10 Source/Destination IP
	   11 Source or	Destination IP
	   12 IP protocol
	   13 octets for flow duration plot data
	   14 packets for flow duration	plot data
	   15 short summary
	   16 IP Next Hop
	   17 Input interface
	   18 Output interface
	   19 Source AS
	   20 Destination AS
	   21 Source/Destination AS
	   22 IP ToS
	   23 Input/Output Interface
	   24 Source Prefix
	   25 Destination Prefix
	   26 Source/Destination Prefix
	   27 Exporter IP
	   28 Engine Id
	   29 Engine Type
	   30 Source Tag
	   31 Destination Tag
	   32 Source/Destination Tag

       -h	 Display help.

       -n	 Use symbolic names where appropriate.

       -p	 Display header	information.

       -P	 Report	as percent total.

       -s sort_field
		 Sort ascending	on field sort_field.

       -S sort_field
		 Sort descending on field sort_field.

       -t tally_lines
		 Tally totals every tally_lineslines.

       -T title	 Set report title to title.

       -w	 Wide output.

EXAMPLES
       Provide a report	on top source/destination IP pairs sorted  by  octets,
       report  in  percent  total  form	for the	flows in /flows/krc4.  Use the
       preload option to flow-cat to preserve meta information and display  it
       with flow-stat.

	 flow-cat -p /flows/krc4 | flow-stat -f10 -P -p	-S4

EXAMPLES
       Many  times a campus network will have a	single border router which has
       one interface pointing to the internal side and many interfaces	point-
       ing  to other providers.	 These interfaces each have a unique numerical
       id known	in SNMP	terms as an ifIndex.  The ifIndex  to  interface  name
       mappings	 can  be  determined by	using a	tool such as snmpwalk or using
       show commands in	recent versions	of IOS with the	'show snmp  mib	 ifmib
       ifindex'	 or JunOS 'show	interfaces'.  Once the ifIndex for each	inter-
       face is known flow-filter can be	combined with flow-stat	to provide re-
       ports such as inbound vs	outbound top src/destination IP	addresses.

       Provide	a top source IP	address	report by outbound traffic, ie the top
       senders of traffic on the campus	network.  Assume the  ifIndex  of  the
       campus interface	is 5.

	 flow-cat -p /flows/krc4 | flow-filter -i5 | flow-stat -f9 -P -p -S3

EXAMPLES
       Provide a top destination IP address report by outbound traffic,	ie the
       top sinks of traffic on the campus network.  Assume the ifIndex of  the
       campus interface	is 5.

	 flow-cat -p /flows/krc4 | flow-filter -I5 | flow-stat -f8 -P -p -S3

EXAMPLES
       Provide a top source/destination	AS report.  Use	symbolic names.

	 flow-cat -p /flows/krc4 | flow-stat -f20 -n -P	-p -S4

BUGS
       None known.
