vSphere ESXI主机网络分析工具

1、net-stats

该命令可以收集端口统计信息。可以通过net-stats -h命令显示所有标志。最常见的是使用net-stats -l来确定所有VMkernel接口、vmnic上行链路和vNIC端口的交换机端口号和MAC地址。

1.1 查看所有支持的标志

[root@localhost:~] net-stats -h

Usage:

         -l                 : List ports in system

         -a                 : Print absolute counts instead of per second counts

         -c :   : specify vsi-cache files instead of live kernel

         -d          : verbose/debug level

         -f                 : ignore version check

         -h                 : this message

         -i       : Interval for stats collection (default=30 seconds)

         -n     : number of iterations to run (default = 1)

         -o        : output file

Specify ports of interest as one of (Prioritized List of options)

         -A                 : Get stats for all ports on host

         -S     : switch name

                 Lists stats for all non mgmt/test ports

         -N       : pnic name

                 List stats for all ports on switch that contains 'N'

         -V         : VM name

                 Find switches that contains the VM's ports. Print stats for VM's ports and uplinks

         -s                 : Get storage world stats

         -I                 : Get SCSI and VSCSI storage I/O stats

         -D           : Name of SCSI device/adapter/path or VM

                              To be used along with storage stat specs

                              Can be used multiple times

                              eg: net-stats -I -ta -D vmhba0 -D vmhba1

OR specify port spec on command line

         -p         : portNum

         -t           : specify a string with types of stats needed

OR specify port spec in a config file

         -C        : config file to read stats from

                 File Format:

Stats Spec can contain one or more of these characters

                 c : Coalesce Stats: Only for vnics

                 i : Interrupt stats: Only for vmnics

                 h : Cluster and Packet size histograms

                 v : virtual nic stats

                 e : Detailed error stats

                 q : Queue Stats for port/nic

                 Q : Detailed Queue stats for the port/nic

                 f : Detailed Queue filter information for port/nic

                 W : world stats for the tx, vmnic/vmknic worlds

                 V : vcpu histograms

                 S : System time breakdown by pcpus

                 n : NIOC stats

                 p : Passthru/sriov stats

                 P : Detailed sriov/passthru stats

                 E : Enable stats collection for ENS module

                     For ENS lcore stats:

                         lcore in : vnic tx/pnic rx

                         lcore out : vnic rx/pnic tx

                 I : IOChain InputFilters stats

                 O : IOChain OutputFilters stats

Stats Spec for Storage stats (-I)

                 d : SCSI Device Stats

                 a : SCSI Adapter Stats

                 t : SCSI Path Stats

                 s : VSCSI Stats

Note:

        net-stats reads multiple vsi nodes, one at a time, using system calls

        As data in the vsi nodes are continuously updated, there is going to

        be some inconsistency in numbers, hopefully, not a lot

         For ENS lcore stats:

                 lcore in : vnic tx/pnic rx

                 lcore out : vnic rx/pnic tx
