Ubuntu Manpage: ratop - display and update sorted network flow data

Provided by: argus-client_3.0.8.2-5ubuntu1_amd64

NAME

       ratop - display and update sorted network flow data

SYNOPSIS

       ratop [raoptions] [-- filter-expression]

DESCRIPTION

       Ratop  reads  argus(8)  data  from  an  argus-file,  or  from  a  remote  data source, and
       periodically displays a sorted list of network flow records.  When read from a file, ratop
       displays the resulting flow caches when the file is completed, updating its status display
       line with each input.  When reading from a live argus  data  stream,  ratop  will  display
       data, asynchronously in realtime, as it is received from the source.

       Flow  data  is  aggregated  as its read, (see racluster.1), resulting in a single line for
       each network transaction encountered in the data stream.  The default sorting key is total
       packets  per  flow,  but other keys can be used instead.  Flow records that have been idle
       for more than the default 60s are removed.  Various output options, such as  the  specific
       columns of data to display, the entry idle timeout value, the screen refresh rate, etc ...
       are all configurable.

       ratop uses ncurses and readline.3, when available, to provide a vi.1  look  and  feel  for
       displaying, navigating and modifying network flow data.

       While  running ratop a lot of help can be obtained from the on-line help system, using the
       ":h" command.

OPTIONS

Command line option specifications are processed from left to right. Options can be
specified more than once. If conflicting options are specified, later specifications
override earlier ones. This makes it viable to create a shell alias for ratop with
preferred defaults specified, then override those preferred defaults as desired on the
command line.

ratop, like all ra based clients, supports a number of ra options including filtering of
input argus records through a terminating filter expression, and the ability to specify
the output style, format and contents for printing data. See ra(1) for a complete
description of ra options. ratop(1) specific options are:

-m aggregation object
Supported aggregation objects are:
none use a null flow key.
srcid argus source identifier.
smac source mac(ether) addr.
dmac destination mac(ether) addr.
soui oui portion of the source mac(ether) addr.
doui oui portion of the destination mac(ether) addr.
smpls source mpls label.
dmpls destination label addr.
svlan source vlan label.
dvlan destination vlan addr.
saddr/[l|m] source IP addr/[cidr len | m.a.s.k].
daddr/[l|m] destination IP addr/[cidr len | m.a.s.k].
matrix/l sorted src and dst IP addr/cidr len.
proto transaction protocol.
sport source port number. Implies use of 'proto'.
dport destination port number. Implies use of 'proto'.
stos source TOS byte value.
dtos destination TOS byte value.
sttl src -> dst TTL value.
dttl dst -> src TTL value.
stcpb src -> dst TCP base sequence number.
dtcpb dst -> src TCP base sequence number.
inode[/l|m]] intermediate node IP addr/[cidr len | m.a.s.k], source of ICMP
mapped events.
sco source ARIN country code, if present.
dco destination ARIN country code, if present.
sas source node origin AS number, if available.
das destination node origin AS number, if available.
ias intermediate node origin AS number, if available.

-M modes
Supported modes are:
correct Attempt to correct the direction of flows by also searching the
reverse flow key, if a match isn't found in the cache. This mode is
on by default when using the default full 5-tuple flow key
definitions.
nocorrect Turn off flow correction for direction. This mode is used by
default if the flow key has been changed.
preserve Preserve fields when aggregating matching flow data.
nopreserve Do not preserve fields when aggregating matching flow data.
norep Do not generate an aggregate statistic for each flow. This is used
primarily when the output represents a single object. Primarily
used when merging status records to generate single flows that
represent single transactions.
rmon Generate data suitable for producing RMON types of metrics.
nocurses Do not use the curses interface to present data. This option is
primarily used when debugging ratop, to get around the issues of
screen maniuplation within a debugger like gdb or lldb.

DISPLAY

The first several lines of the ratop display show global state. The top line shows how
ratop is running, with the list of command line options that are in effect. In the upper
most right corner is the current time. The next line is the column title line, that
labels each column. The bottom line is the command line, where you will see and prepare
':' commands. The line above the bottom line is the status line, showing the number of
flows that are in the ratop process queue, display queue, the total number of flows read,
the rate of flow records read, and the current status, whether it is Active, reading
records, or Idle, when all input is complete. This line can be toggled on or off using
^G.

Flows caches are displayed one per row and are sorted by total pkts, by default. ratop
sorting can be configured using the rarc variable RA_SORT_ALGORITHMS, or by using the ":P"
command.

ratop supports 3 basic filters. Like all other ra* programs, ratop will send its command
line filter to its remote argus data sources, to limit the load on the wire. This is the
"remote" filter. Also, ratop supports a "local" filter, that is applied to flow record
input. Normally this is used when the remote argus data source doesn't support the syntax
of the specific filter. ratop also support a "display" filter, that is used to select
which flow records are to be displayed. This filter does not have any impact on the
internal flow caches that ratop is tracking, so you can change the "display" filter at any
time and see the current state of other flows.

COLOR

       ratop supports color which is configured using the rarc file.  The RA_COLOR_CONFIG file is
       a  fall through specification of flow filters and field color definitions.  For flows that
       match a filter, specific fields in the row will be painted the configured color.   Because
       the  filter  specification supports the " cont " directive, a single row can be painted by
       any number of color definitions.

       When color is enabled ratop will attempt to color IP addresses to indicate that local host
       address,  and the local network.  This is very helpful in mobile host installations, where
       you may not know what IP address has been assigned the  localhost.   ratop  also  supports
       coloring local addresses based on the RA_LOCAL rarc variable.

       See racolor.conf.5.

ARGUS EVENTS

       Introduced  in argus-3.0.8, ratop supports correlating specific ARGUS_EVENT data with flow
       data, which can be turned on through the use of  the  RA_CORRELATE_EVENTS  rarc  variable.
       ratop  will  process  argus-lsof  event data generated by host bourne argi, and label flow
       data with user, pid and process name metadata.  While experimental, it is production level
       functionality,  and  can be used with other ra* programs to enhance flow data with host os
       process information.  See argus-3.0.8 documentation on ARGUS_EVENTS.

EXAMPLES

       ratop -r argus.file -s rank stime dur:14 saddr daddr proto pkts bytes

              Read the file argus.file, and display the resulting aggregated and sorted  list  of
              flow records, using the default sorting methods.

       ratop -S localhost
              Run ratop as a live display of realtime flow traffic.
