vSphere Automation API GET `/api/appliance/monitoring` response changed for the swap, storage, memory and disk category metrics

Products

• VMware vCenter Server

Issue/Introduction

In vSphere Automation API 7.x the returned response of GET /api/appliance/monitoring would return specific metrics that are not found when running the same query in vSphere Automation API 8.x without any change in the documentation.

Environment

VMware vCenter Server 7.x

Cause

There was a change in the metrics collection in backend between vCenter 7.x and vCenter 8.x and the unwanted/unused metrics from the VAMI UI have been removed for better data management, performance and UI requirement. 

This change in metrics availability was not publicly documented.

Resolution

The following stat IDs were removed in vSphere Automation API 8.x:

swap.util
storage.used.filesystem.swap
swap
storage.totalsize.filesystem.swap
storage.util.filesystem.swap
storage.totalsize.filesystem.root
