Is there an equivalent to volume latency in Unified Manager by using ONTAP CLI or SNMP?
Applies to
- Active IQ Unified Manager
- OnCommand Unified Manager
- ONTAP 9
Answer
Unified Manager captures performance data every 5 minutes by retrieving ccma files that are generated on each node of a cluster. This is not real-time but based on one minute samples captured on the cluster.
You can navigate in Unified Manager to a particular volume and see the latency, iops, and throughput. You can also switch to the breakdown charts to get
further details such as read,write,other.
The closest equivalent via cli will be 'qos statistics volume performance show
'
pstejska_vsim::*> qos statistics volume performance show Workload ID IOPS Throughput Latency --------------- ------ -------- ---------------- ---------- -total- - 54 3.38MB/s 1232.36ms test_cifs_hom.. 13990 54 3.38MB/s 1232.36ms -total- - 54 3.38MB/s 1095.44ms test_cifs_hom.. 13990 54 3.38MB/s 1095.44ms -total- - 54 3.38MB/s 1210.90ms test_cifs_hom.. 13990 54 3.38MB/s 1210.90ms -total- - 54 3.38MB/s 887.71ms test_cifs_hom.. 13990 54 3.38MB/s 887.71ms pstejska_vsim::*>
**Please note that this may not match numbers seen in Unified Manager based on when the information is captured**
