環境

  • ONTAP 9
  • Cloud Volumes ONTAP(CVO)for Azure

問題

  • ONTAPからディスクから高レイテンシが報告される
    • 例: 実行中の qos statistics volume latency show DISK列のレイテンシが高くなっています
Cluster::> qos statistics volume latency show Workload ID Latency Network Cluster Data Disk QoS NVRAM Cloud --------------- ------ ---------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- -total- - 8.88ms 2.82ms 1.00us 1032.00us 5.02ms 0ms 2.00us 0ms vol1-wid34121 34121 137.73ms 1.91ms 1.00us 22.93ms 112.89ms 0ms 0ms 0ms vol2-wid34122 34122 133.29ms 1.82ms 0ms 2.84ms 128.62ms 0ms 0ms 0ms vol3-wid34123 34123 78.48ms 1.96ms 0ms 7.69ms 68.83ms 0ms 0ms 0ms vol4-wid34124 34124 50.51ms 239.00us 0ms 995.00us 49.28ms 0ms 0ms 0ms
  • 監視ソフトウェアでは、Active IQ Unified ManagerやHarvestの[Aggregate]ビューなど、利用率の急上昇が表示されることがあります。
