  Visualizing Network Traffic with Netflow and FlowScan
Subject:   Problem with flowscan..?

I followed all the directions from both articles, except that I'm using NetFlow on my Cisco router.


I'm running RELENG_6_0.


When I start flowscan, it complains bout not being able to update the .rrd files:


ERROR updating /var/log/cuflow/protocol_tcp.rrd: Not enough arguments
ERROR updating /var/log/cuflow/gateway/protocol_tcp.rrd: Not enough arguments
ERROR updating /var/log/cuflow/protocol_icmp.rrd: Not enough arguments
ERROR updating /var/log/cuflow/gateway/protocol_icmp.rrd: Not enough arguments
ERROR updating /var/log/cuflow/protocol_udp.rrd: Not enough arguments
ERROR updating /var/log/cuflow/gateway/protocol_udp.rrd: Not enough arguments


It prints out about 60 lines of this.


It looks like the scoreboard and aggregate html pages are being generated, but I'd love to be able to use the CUGrapher.pl script.


Any help would be much appreciated!
