opFlow don't show any traffic information from Cisco ASA Both flowd and opflowd is running. Flowd directory contains flows data, /data/opflow/flowd contain information what can be readed by flows-reader. But on opFlow page traffic is zero everywhere. Totals: Flows: 0, Packets: 0, Bytes: 0, 0.000MB What wrong? Cisco model - ASA5510 Thank you
Newer Cisco ASA devices are using NSEL which is not NetFlow, if you can configure your ASA to send NetFlow opFlow will be able to show you the information.
