Hi there, As of 17.10 you can now register for statistics on a per interface level.
You need the sw_if_index of the interface you want stats for, but the calls are in https://git.fd.io/vpp/tree/src/vpp/stats/stats.api but as an example: Register: autoreply define want_per_interface_simple_stats { u32 client_index; u32 context; u32 enable_disable; u32 pid; u32 num; u32 sw_ifs[num]; }; So calling "want_per_interface_simple_stats" with enable_disable=1, num=1 and sw_ifs[4] will give you interface_simple_stats every 10sec for sw_if_index=4. The content of "interface_simple_stats" looks like: /** \brief Simple per interface stats counters structure @param count - number of elements in message @param timestamp - u32 vlib timestamp for control plane @param data[count] - vl_api_vnet_simple_counter_t */ manual_print manual_endian define vnet_per_interface_simple_counters { u32 count; u32 timestamp; vl_api_vnet_simple_counter_t data[count]; }; Where each "vnet_simple_counter_t" looks like: https://git.fd.io/vpp/tree/src/vnet/interface.api /** \brief Simple interface counter data type for vnet_interface_simple_counters @param sw_if_index - interface indexes for counters @param drop - RX or TX drops due to buffer starvation @param punt - used with VNET "punt" disposition @param rx_ip4 - received IP4 packets @param rx_ip6 - received IP6 packets @param rx_no_buffer - no RX buffers available @param rx_miss - receive misses @param rx_error - receive errors @param tx_error - transmit errors @param rx_mpls - received MPLS packet */ typeonly manual_print manual_endian define vnet_simple_counter { u32 sw_if_index; u64 drop; u64 punt; u64 rx_ip4; u64 rx_ip6; u64 rx_no_buffer; u64 rx_miss; u64 rx_error; u64 tx_error; u64 rx_mpls; }; So you will get back an array of counter structs for each sw_if_index you registered for. At the moment the impl sends on sw_if_index per reply but that is going to change so that for each client we send as much in one message as possible.
