CM table for exporting object store operation statistics. Object store operations are HTTP operations sent over TCP to manage objects on any object store.

This represents the construction of the row ID field, which is a single unique string that identifies a row.

Properties

This section describes the mapping between classic (ONTAPI) string counter names and REST property names.

Classic String Counter REST Property Description

node_name

node.name

System node name

Counters

This section describes the mapping between classic (ONTAPI) numeric counter names and REST counter names.

Classic Numeric Counter REST Counter Description

stats

stats

Counter that indicates the number of object store operations sent, and their
success and failure counts for particular handle and particular object store
commands.

ops

ops

Counter that indicates the number of object store operations in total for
particular handle and particular object store commands. This counter acts as a
base counter for average_latency.

average_latency

average_latency

Average latencies executed during various phases of command execution. The
execution_start latency represents the average time taken to start executing an
operation. The request_prepare latency represents the average time taken to
prepare the complete request that needs to be sent to the server. The send
latency represents the average time taken to send requests to the server. The
execution_start_to_send_complete represents the average time taken to send a
request since its execution started. The execution_start_to_first_byte_received
latency represents the average time taken to receive the first byte of a
response since the command's execution started. These counters can be used to
identify performance bottlenecks within the object store client module. This
counter contains average latency for a particular handle and a particular object
store command.

throughput_bytes

throughput_bytes

Counter that indicates the throughput for the corresponding object store command
in bytes per second.

throughput_ops

throughput_ops

Counter that indicates the throughput for commands in operations per second.

Property/Counter Content Changes

This section describes any output value differences between the classic (ONTAPI) string counter and the respective REST property. It also describes array label name changes between classic array counters and respective REST array counters.

REST Counter Description

ops

The counter labels have changed. All of the dashes '-' in the labels were changed to underscores '_'.

average_latency

The counter labels have changed. All of the dashes '-' in the labels were changed to underscores '_'.
