This mapping documentation can help you continue meeting your ONTAP performance and monitoring objectives. It provides a list of the performance counter tables accessible through the ONTAP 9.12.1 REST API with a description of every counter. Each table also includes details about how the performance counters are related to the equivalent values available with the earlier ONTAPI API. This mapping information is designed to assist and support the migration of your ONTAP automation code from ONTAPI to the ONTAP REST API. More details about the documentation and how to use it are presented below.

Transition from objects to tables

The ONTAPI API, also referred to as the Zephyr API (ZAPI), is available through the NetApp Network Manageability SDK. ONTAPI presents the ONTAP performance data as a collection of objects each with a set of counter properties. The REST API provides the equivalent data in a table format for a subset of the ONTAPI objects. Navigation begins in the sidebar with a list of the performance counter tables that are accessible through the REST API.

Consistent description of each table

The description of every table is based on a consistent format. After a brief introduction and an indication of the related ONTAPI object, the following sections are included.

  • Table row IDs

    Each counter table is accessed through a unique ID. This section provides a list of the one or more ID formats supported for the table.

  • Properties

    This section includes the names of the ONTAPI string counters and the equivalent REST property for each.

  • Counters

    There is also a mapping from the numeric ONTAPI counters to the equivalent REST counters.

  • Content changes

    Any changes from the ONTAPI string counters to the respective REST properties are described here.

  • Table aliases

    This section includes a description of any aliases for the aggregated tables.
