flow-rpt2rrd 1 flow-rpt2rrd Convert flow-report CSV output to RRDtool format. flow-rpt2rrd -nv -d debug_level -k keys -K keys_file -f fields -p rrd_path -P rrd_postfix -r rrd_storage 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. -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. 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. #!/bin/sh cat << EOF>report.cfg include-filter nfilter.cfg stat-report CLMBO-R4-TO-INTERNET-BY-DESTINATION-AS type destination-as filter CLMBO-R4-INTERNET-OUT scale 100 output options +header,+xheader fields -duration stat-definition 5min-summaries report CLMBO-R4-TO-INTERNET-BY-DESTINATION-AS EOF cat << EOF>nfilter.cfg # ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.46 = so-0/0/0.0 filter-primitive CLMBO-R4-INTERNET type ifindex permit 46 # Match on traffic to the Internet filter-definition CLMBO-R4-INTERNET-OUT match output-interface CLMBO-R4-INTERNET EOF mkdir rrds # 5 minute flow files from flow-capture are here FLOW_DATA=/flows/clmbo-r4/2004-11-08/ # for each 5 minute flow,aggregate with flow-report then store to RRD for name in $FLOW_DATA/*; do echo working...$name flow-report -s report.cfg -S5min-summaries < $name | flow-rpt2rrd -k10796,6478 -p rrds done # first flow - 0:1:23 11/8/2004 START=1099890083 # last flow - 0:1:25 11/9/2004 END=1099976485 rrdtool graph CLMBO-R4-TO-INTERNET.png --start $START --end $END \ --vertical-label "Bits/Second" --title="CLMBO-R4 TO INTERNET BY AS" \ DEF:AS10796in=rrds/10796.rrd:octets:AVERAGE \ DEF:AS6478in=rrds/6478.rrd:octets:AVERAGE \ CDEF:b_AS10796in=AS10796in,8,* \ CDEF:b_AS6478in=AS6478in,8,* \ LINE1:b_AS10796in#FF0000:AS10796-in \ LINE1:b_AS6478in#555555:AS6478-in \ Hard coded to expect 5 minute flow file intervals.
