NAME

flow-rpt2rrd — Convert flow-report CSV output to RRDtool format.

SYNOPSIS

flow-rpt2rrd [-nv] [-d debug_level] [-k keys] [-K keys_file] [-f fields] [-p rrd_path] [-P rrd_postfix] [-r rrd_storage]

DESCRIPTION

The flow-rpt2rrd utility processes the CSV output of flow-report into RRDtool format. The aggregates for a key are each stored as a DS in RRD filename {rrd_path,"/",key,rrd_postfix,".rrd"}. By default a DS is created for flows, octets, and packets. The key must be specified, for example an ip-port report could use smtp,nntp,ssh,telnet as the keys which would create a separate RRD for each key.

OPTIONS

-d debug_level: Set debug level to debug_level (debugging code)
-h: Help.
-k keys|html: Comma separated list of key values. If the report has symbols then the key must be the symbol, ie smtp not 25. The totals_* lines may be used if they are enabled in the report. There is no default, keys must be specified with -k or -K.
-K keys_file: Load keys from keys_file. See -k.
-f: Comma separated list of columns to store. Each column maps to a DS in the RRD. Defaults to flows,octets,packets
-n: Enable symbol table lookups. For example TCP port 25 = smtp. This will result in RRD file names with the symbolic names if symbol lookups were not enabled in the report.
-p rrd_path: Set path to RRD files. Defaults to ".".
-P rrd_postfix: Set RRD file name postfix. Defaults to "".
-r rrd_storage: Set RRD storage for 5 minute, 30 minute, 2 hour, and 1 day databases. List items are : seperated. Defaults to 600:600:600:732.
-v: Enable verbose output.

EXAMPLES

The following example shows the combined use of flow-nfilter (inline), 
flow-report, and flow-rpt2rrd to create an RRD depicting traffic 
from clmbo-r4 to AS 10796 and 6478 for 2004-11-08.  rrdtool graph is
then used to create a .png.

BUGS

Hard coded to expect 5 minute flow file intervals. Does not properly parse flow-report time-series output.
