We want to monitor the bandwith usage of our Cisco ASA 5510. We have setup the monitoring with SNMP and this works fine. Now we would like to see the traffic from a single server (IP). We have tried to setup netflow to get the statistics for this server, but Traffic Grapher doesn't recive any data from the Cisco with netflow. We have setup the netflow9tester and this tool does see all the data.
Do you have any idea what could be going wrong with Traffic Grapher and the netflow data?
