ONTAP Network Processing latency - Troubleshooting Guide
Applies to
ONTAP 9
Description
- Network Processing (AIQUM) or Network (CLI) refers to ONTAP's processing associated with the network stack and protocol handling
- These delay centers may also be referred to as "CPU N-Blade"
- CPU N-blade delay is usually shown as follows:
- Active IQ Unified Manager: latency shown in Network Processing
- Command line
qos statistics volume latency show: latency shown in the Network column
Example:
Cluster::> qos statistics volume latency show
