How to interpret the QoS ratebucket ID
Applies to
- ONTAP 9
- QoS
- Counter Manager Object ratebucket
Description
- Object ratebucket is critical in QoS related analysis
- The counter instance_name in object ratebucket is organized in the format :
<prefix>.ID- Prefix NG manages NAS traffic (NFS + CIFS)
- Prefix SC manages Block traffic (iSCSI, FC, NVME)
- Prefix qw manages system workloads
- Ratebucket ID in instance_name could be used to map to the corresponding volume/workload
- Example: Workload ID 7398 maps to ratebucket ID 2147491046 in the following outputs (2147483648 + 7398 = 2147491046).

- This article providies a procedure to map the instance_name to the corresponding volume/workload in both scenarios
- Shared QoS Policy Groups
- Non-shared QoS Policy Groups
- Adaptive QoS Policy Groups
