qos
A workload represents work being done on behalf of an application or system process. The QoS Counter Manager table reports information such as operations per second, a breakdown of where read operations are going, the inter-arrival time of operation request messages, working set size information, operation latency per workload, and deferred workload information. These statistics illustrate system performance with given workloads. The alias name for qos:policy_group is qos_policy_group.

Table Row IDs
ID Format | Aggregation Type | Comment |
---|---|---|
{instance_name}:{instance_uuid} |
(not applicable) |
This represents the construction of the row ID field, which is a single unique string that identifies a row. |
{node.name}:{instance_name}:{instance_uuid} |
constituent |
This represents the construction of a row ID field for a row from a single node. |
{policy_group_name}:{policy_group_uuid} |
policy_group |
This represents the construction of the row ID field in policy_group combo object, which is a single unique string that identifies a row. |
