Active IQ Unified Manager, qos or statistics commands missing IOPS or latency for some nodes

Applies to

• OnCommand Unified Manager 7.2 or later
• Active IQ Unified Manager
• OnCommand System Manager
• Active IQ
• ONTAP 9
• qos statistics commands
• statistics node show command

Issue

• Some nodes may display zeros (0) for latency or zero IOPs when viewing the node page in Active IQ Unified Manager or Active IQ on node tab
• A node is not sending or receiving traffic on any of the available physical interfaces so there are 0 IOPS displayed for the node in Unified Manager
• statistics node show has 0 Ops, Bytes, or latency for a node
• qos statistics commands filtered with -node show blank

Example: node02 has 0 IOPS due to no data LIF on that node
