Hi, I'm a bit confused on how I use the ZC PF_RING drivers with n2disk and ntopng.
I've installed all of the latest stable packages from ntop.org. When I first brought up the box, ingress traffic was going to n2disk and ntopng just fine, but the box was showing lots of drops in ifconfig. I went into the nbox GUI under system>PF_RING and enabled the ZC ixgbe driver. After rebooting, n2disk now showed a bunch of zc:eth interfaces. So I went to Application>Cluster and clustered all of the zc:eth4 interfaces together, and created a new cluster with two applications. I configured n2disk to use cluster_1_0, and it appears to be working, but ntopng isn't gathering any data, no matter if I set it to eth4, zc:eth4, or cluster_1_1. Can someone help me understand what I'm missing? Here are some details about my box: [root@SAV-NBOX1 ntopng]# cat /proc/net/pf_ring/info PF_RING Version : 6.2.0 (6.2.0-stable:c69bec0486fc2afc6f499659f680c37ef1c72026) Total rings : 20 Standard (non DNA/ZC) Options Ring slots : 4096 Slot version : 16 Capture TX : No [RX only] IP Defragment : No Socket Mode : Standard Total plugins : 0 Cluster Fragment Queue : 0 Cluster Fragment Discard : 0 [root@SAV-NBOX1 ntopng]# cat /proc/net/pf_ring/dev/eth4/info Name: eth4 Index: 8 Address: 5C:B9:01:96:49:64 Polling Mode: NAPI/ZC Type: Ethernet Family: Intel ixgbe 82599 Max # TX Queues: 16 # Used RX Queues: 16 Num RX Slots: 32768 Num TX Slots: 32768 Thanks, Brandon
