NAME

rastrip - strip argus(8) data file. Copyright (c) 2000-2003 QoSient. All rights reserved.

SYNOPSIS

rastrip [[-M stripfield] [stripfield] ...] [raoptions]

DESCRIPTION

Rastrip reads argus data from an argus-data source, and removes data sections that are specified on the command line, and outputs a valid argus-stream. If rastrip is run without any stripfield directives, the default is to strip out all information from the record except the FAR information and TCP specific information. This default generates an argus-stream that contains the same semantic information that was present in argus-1.5 data records, and generates the same output from ra().

OPTIONS

Rastrip, like all ra based clients, supports a number of ra options including filtering of input argus records through a terminating filter expression. See ra(1) for a complete description of ra options. rastrip(1) specific options are:
-M [-|+]stripfield

Supported stripfields are:

far
flow descriptors and flow metrics
mac
media access control addresses
tcp
TCP specific identifiers and metrics, such as base sequence numbers, advertised window sizes and retransmission statistics.
icmp
ICMP specific identifiers and metrics, such as the source address of the ICMP packet, the declared gateway address and the ICMP types and modes, such as ECHO or Port Unreachable, along with the port value.
rtp
RTP and RTCP specific identifiers and metrics, such as the source stream identifiers, the last sequence number and stream drop statistics.
igmp
IGMP specific identifiers and metrics.
arp
IGMP specific identifiers and metrics, such as the MAC address of the responder to arp requests for a specific address.
frag
Fragmentation specific identifiers and metrics, such as the average fragment size, number of fragments in this fragment, last offset seen in this fragment.
esp
ESP specific identifiers and metrics, such as the Security Identifier the last sequence number seen and drop statistics.
mpls
MPLS specific identifiers, such as the last MPLS label seen on this flow.
vlan
VLAN specific identifiers, such as the source and destination VLAN identifiers. flow.
pppoe
PPPOE specific identifiers, such as the source and destination SAP identifiers.
agr
Aggregation specific metrics, such as the number of records aggregated, the mean record duration, standard deviations.
jitter
Jitter specific metrics, such as the mean interpacket arrival time while the flow is active, max, min and standard deviation, as well as metrics for while the flow is idle.
user
All user data capture buffers.
srcuser
User data capture buffer from the source node.
dstuser
User data capture buffer from the destination node.
stime
Source jitter information.
dtime
Destination jitter information.

INVOCATION

Sample invocations of rastrip(1). The first call reads argus(8) data from inputfile and strips the record, leaving only the FAR data, which contains the flow descriptors and basic metrics, and jitter information.
 
    rastrip -r inputfile -M far jitter
 

The next sample invocation of rastrip(1), adds vlan specific information to the default far and tcp information that would normally be retained.

 
    rastrip -r inputfile -M +vlan
 

The next sample invocation of rastrip(1), removes only the user data capture buffers from the argus-stream, keep the rest of the data intact.

 
    rastrip -r inputfile -M -user
