racluster — aggregate argus(8) data files.

Synopsis

racluster [-f conf] [-m agr(s)] [-M mode(s)] [raoptions] [-- filter-expression]

Description

Racluster reads argus data from an argus-data source, and clusters/merges the records based on the flow key criteria specified either on the command line, or in a racluster configuration file, and outputs a valid argus-stream. This tool is primarily used for data mining, data management and report generation.

The default action is to merge status records from the same flow and argus probe, providing in some cases huge data reduction with limited loss of flow information. Racluster provides the ability to modify the flow model key, either using the "-m" option, or in the racluster.conf file, allowing records to be clustered based on any number of attributes. This supports the development of important reports, such as MPLS LSP usage statistics, DiffServe flow marking policy verification, VLAN group behavior, IP distance related measurements, routing loop detection, traceroute path data recovery, and complex availability/reachability reports, to name just a few useful applications.

Please see racluster.5 for detailed information regarding racluster configuration.

Options

Racluster, 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. racluster(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.
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.
ind
Process each input file independantly, so that after the end of each inputfile, racluster flushes its output.
replace
Replace each inputfile contents, with the aggregated output. The initial file compression status is maintained
-V
Verbose operation, printing a line of output for each input file processed. Very useful when using the ra() -R option.

Invocation

A sample invocation of racluster(1). This call reads argus(8) data from inputfile and aggregates the TCP protocol based argus(8) data. By default, racluster(1) merges using the standard 5-tuple flow key. This method is used to merge multiple status records into a single flow record per transaction.

A sample invocation of racluster(1). This call reads argus(8) data from inputfile and aggregates the TCP protocol based argus(8) data, based on the source and destination address matrix and the protocol. It reports the metrics as a percent of the total.
