    • WAFL latency
  • Note: This is a secondary article on how to troubleshoot ONTAP 9 performance, please see the main ONTAP 9 performance troubleshooting Resolution Guide
  • Using Active IQ Unified Manager or commands such as qos statistics volume latency show, latency is shown to be in the Data (CLI) or Data Processing (Active IQ Unified Manager), and latency is actively impacted on the target volume. 

Example:

Cluster::> qos statistics volume latency show
Workload            ID    Latency    Network    Cluster       Data       Disk        QoS      NVRAM
