Counter Manager object for exporting WAFL performance counters

Classic Object: wafl

Table Row IDs

ID Format Aggregation Type Comment

{instance_name}

(not applicable)

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

Node Name

instance_name

name

Name of this instance

Counters

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

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

cp_count

Two things were changed about the naming of these array labels:
1. All of the spaces and hyphens were converted to underscores.
2. All of the letters were converted to lowercase.

cp_phase_times

The only difference in the naming for the array labels is that all of the letters were converted to lowercase.

Table Aliases

This section describes aliases for aggregated tables.
