Aria Operations stops collecting data due to large number of distinct NSX BGP Neighbor Instanced Metric metric keys.

Products

• VMware Aria Suite

Issue/Introduction

• Aria Operations shows problems collecting data on all adapters. The issue is temporarily resolved when the cluster is taken offline/online but will reoccur.
• /storage/db is filling up, and cluster may go offline automatically due to running out of storage at 96% usage. 

Environment

Aria Operations 8.x

Cause

NSX-T Management Pack  can generate a huge number of distinct BGP Neighbor Instanced Metric metric keys,  these metrics lead to a few objects having very large FSDB data files, which appears to impact the performance of saving these metrics, it leads to other performance issues, like collections not completing normally.
