In 22addition, each group of counters may have different counter types. 23 24These counter groups are based on which component in a networking setup, 25illustrated below, that they describe:: 26 27 ---------------------------------------- 28 | | 29 ---------------------------------------- ---------------------------------------- | 30 | Hypervisor | | VM | | 31 | | | | | 32 | ------------------- --------------- | | ------------------- --------------- | | 33 | | Ethernet driver | | RDMA driver | | | | Ethernet driver | | RDMA driver | | | 34 | ------------------- --------------- | | ------------------- --------------- | | 35 | | | | | | | | | 36 | ------------------- | | ------------------- | | 37 | | | | | |-- 38 ---------------------------------------- ---------------------------------------- 39 | | 40 ------------- ----------------------------- 41 | | 42 ------ ------ ------ ------ ------ ------ ------ 43 -----| PF |----------------------| VF |-| VF |-| VF |----- --| PF |--- --| PF |--- --| PF |--- 44 | ------ ------ ------ ------ | | ------ | | ------ | | ------ | 45 | | | | | | | | 46 | | | | | | | | 47 | | | | | | | | 48 | eSwitch | | eSwitch | | eSwitch | | eSwitch | 49 ---------------------------------------------------------- ----------- ----------- ----------- 50 ------------------------------------------------------------------------------- 51 | | 52 | | 53 | Uplink (no counters) | 54 ------------------------------------------------------------------------------- 55 --------------------------------------------------------------- 56 | | 57 | | 58 | MPFS (no counters) | 59 --------------------------------------------------------------- 60 | 61 | 62 | Port 63 64Groups 65====== 66 67Ring 68 Software counters populated by the driver stack. 69 70Netdev 71 An aggregation of software ring counters. 72 73vPort counters 74 Traffic counters and drops due to steering or no buffers. May indicate issues 75 with NIC. These counters include Ethernet traffic counters (including Raw 76 Ethernet) and RDMA/RoCE traffic counters. 77 78Physical port counters 79 Counters that collect statistics about the PFs and VFs. May indicate issues 80 with NIC, link, or network. This measuring point holds information on 81 standardized counters like IEEE 802.3, RFC2863, RFC 2819, RFC 3635 and 82 additional counters like flow control, FEC and more. Physical port counters 83 are not exposed to virtual machines. 84 85Priority Port Counters 86 A set of the physical port counters, per priority per port. 87 88Types 89===== 90 91Counters are divided into three types. 92 93Traffic Informative Counters 94 Counters which count traffic. These counters can be used for load estimation 95 or for general debug. 96 97Traffic Acceleration Counters 98 Counters which count traffic that was accelerated by Mellanox driver or by 99 hardware. The counters are an additional layer to the informative counter set, 100 and the same traffic is counted in both informative and acceleration counters. 101 102.. [#accel] Traffic acceleration counter. 103 104Error Counters 105 Increment of these counters might indicate a problem. Each of these counters 106 has an explanation and correction action. 107 108Statistic can be fetched via the `ip link` or `ethtool` commands. `ethtool` 109provides more detailed information.:: 110 111 ip –s link show <if-name> 112 ethtool -S <if-name> 113 114Descriptions 115============ 116 117XSK, PTP, and QoS counters that are similar to counters defined previously will 118not be separately listed. For example, `ptp_tx[i]_packets` will not be 119explicitly documented since `tx[i]_packets` describes the behavior of both 120counters, except `ptp_tx[i]_packets` is only counted when precision time 121protocol is used. 122 123Ring / Netdev Counter 124---------------------------- 125The following counters are available per ring or software port. 126 127These counters provide information on the amount of traffic that was accelerated 128by the NIC. The counters are counting the accelerated traffic in addition to the 129standard counters which counts it (i.e. accelerated traffic is counted twice). 130 131The counter names in the table below refers to both ring and port counters. The 132notation for ring counters includes the [i] index without the braces. The 133notation for port counters doesn't include the [i]. A counter name 134`rx[i]_packets` will be printed as `rx0_packets` for ring 0 and `rx_packets` for 135the software port. 136 137.. flat-table:: Ring / Software Port Counter Table 138 :widths: 2 3 1 139 140 * - Counter 141 - Description 142 - Type 143 144 * - `rx[i]_packets` 145 - The number of packets received on ring i. 146 - Informative 147 148 * - `rx[i]_bytes` 149 - The number of bytes received on ring i. 150 - Informative 151 152 * - `tx[i]_packets` 153 - The number of packets transmitted on ring i. 154 - Informative 155 156 * - `tx[i]_bytes` 157 - The number of bytes transmitted on ring i. 158 - Informative 159 160 * - `tx[i]_recover` 161 - The number of times the SQ was recovered. 162 - Error 163 164 * - `tx[i]_cqes` 165 - Number of CQEs events on SQ issued on ring i. 166 - Informative 167 168 * - `tx[i]_cqe_err` 169 - The number of error CQEs encountered on the SQ for ring i. 170 - Error 171 172 * - `tx[i]_tso_packets` 173 - The number of TSO packets transmitted on ring i [#accel]_. 174 - Acceleration 175 176 * - `tx[i]_tso_bytes` 177 - The number of TSO bytes transmitted on ring i [#accel]_. 178 - Acceleration 179 180 * - `tx[i]_tso_inner_packets` 181 - The number of TSO packets which are indicated to be carry internal 182 encapsulation transmitted on ring i [#accel]_. 183 - Acceleration 184 185 * - `tx[i]_tso_inner_bytes` 186 - The number of TSO bytes which are indicated to be carry internal 187 encapsulation transmitted on ring i [#accel]_. 188 - Acceleration 189 190 * - `rx[i]_gro_packets` 191 - Number of received packets processed using hardware-accelerated GRO.
