命令 示例
statistics show-periodic [-node <node name> ]
  • 以下列非常有用:
    • cpu busy 显示CPU域中的CPU使用情况
    • data 列显示了通过节点上的所有NIC传输的以太网吞吐量
    • cluster 列显示通过集群LIF的数据量

sysstat -x 1
  • 以下列非常有用:
    • CPU 指示CPU使用情况
    • CP time 是sysstat输出每行中将一致点从RAM转储或不转储到磁盘的时间( -x 1 如果已指定、则为1秒)
      • 除非对CP进行故障排除、否则此功能将不有用
    • CP_Ty 如果存在背对背CP、则会很有用

sysstat -M 1
  • 以下列非常有用:
    • Nwk_Exmpt 显示网络CPU处理的利用率
    • WAFL_Ex 显示数据处理的利用率(D-Blade或WAFL)

statit
  • 以下列非常有用:
    • ut% 是磁盘向磁盘发送I/O命令而不发送I/O命令的时间百分比除以运行statit的时间
    • xfers 显示每个驱动器的磁盘IOPS平均值
      • xfer 每种类型对于查看IOP细分都很有用
    • chain 是以4 KB为单位的I/O大小
      • 示例: 1个链为4 KB、2个链为8 KB
    • usecs 是每个驱动器的每种IOP类型的微秒延迟

  • filer> priv set advanced
  • filer*> statit -b
  • (等待30秒或更长时间)
  • filer*> statit -e
Disk Statistics (per second) ut% is the percent of time the disk was busy. xfers is the number of data-transfer commands issued per second. xfers = ureads + writes + cpreads + greads + gwrites chain is the average number of 4K blocks per command. usecs is the average disk round-trip time per 4K block. disk ut% xfers ureads--chain-usecs writes--chain-usecs cpreads-chain-usecs greads--chain-usecs gwrites-chain-usecs /aggr0/plex0/rg0: 0a.00.0 1 1.73 0.27 1.00 667 1.36 6.07 352 0.09 1.00 6000 0.00 .... . 0.00 .... . 0a.00.1 1 1.82 0.27 1.00 333 1.55 5.59 495 0.00 .... . 0.00 .... . 0.00 .... . 0a.00.2 20 50.55 10.00 5.00 2200 0.36 20.00 375 0.18 1.00 6000 0.00 .... . 0.00 .... .
