从上述信息看出,tx_packets 没有增长,rx_packet 与 rx_missed 同时在增长,rx_no_buffer_count 为 0 表示没有出现 mbuf 泄露,同时确认网络流量非常少,rx_packets 的数据减掉 rx_missed_errors 的数据大约在一万5千左右,判断问题为程序无法收包。 收包mempool 的 mbuf_size 为 2048 debug 过程记录 1. 查看接...
imissed发生在上述DPDK抓包流程的第二步,表示rte_rx_queue已经塞满了数据包,所以该包被丢失。此时该包存在于物理网卡的RX FIFO中,但是不会存在于内存中的rte_rx_queue中。 ierrors ierrors发生在上述第一步中,表示该数据包存在错误,被网卡丢弃。此时该包不会存在于物理网卡的RX FIFO中,更不会存在于内存中的rte...
rx_nombuf记录在读取数据包时分配mbuf错误的次数,一般情况下不会影响网卡的丢包(imissed、ierrors)。该变量的维护在dpdk-stable-19.11.3/drivers/net/ixgbe/ixgbe_rxtx.c:1651:rx_recv_pkts中。 解决方法 上面讲了那么多,那么如何才能降低丢包呢? imissed 如上所述imissed表示从网卡到内存写入数据包时的丢包个数...
Most drivers interchange their use of the counters rx_missed_errors, rx_fifo_errors, and rx_over_errors, but they typically set one or more of these counters to the MPC (missed packet count) counter, which is incremented when a packet arrives and is lost because the card's FIFO queue is...
DPDK DPDK之什么是imissed、ierrors、rx_nombuf 摘要:DPDK之什么是imissed、ierrors、rx_nombuf 在采用DPDK进行网络抓包时常常会通过rte_eth_stats_get函数获取当前网卡的丢包状态,首先看一下该函数的声明: // 函数声明(dpdk-stable-19.11.3/lib/librte_ethdev/rte_eth 阅读全文 posted...
when the traffic reached 20Gbps(about 5 Gbps for each physical port), I found some packets are dropped by HW everytime because of no mbuf in the rx rings which is called as imissed errors in struct rte_eth_stats. I use 4 cores for RSS, set the nb_desc t...
