How to enable Performance Telemetry in vRealize Network Insight

Products

• VMware Aria Operations for Networks

Issue/Introduction

To help troubleshoot customer issues in vRealize Network Insight, there is an option to enable telemetry for performance metrics. Customers can enable or disable this from the product CLI.
 
When enabled, vRealize Network Insight sends periodic performance metrics about vRealize Network Insight performance & subsystems. The information is sent in an encrypted fashion to the vRealize Network Insight cloud.
 
This information is ONLY about the internal data structures and processing in vRealize Network Insight.
This DOES NOT include any information about the customer environment or any PII.
 
The information sent includes:

• Number of containers in the vRealize Network Insight compute grids that are active
• The CPU and memory consumption of each of this grid
• The various analytics programs running within each of the containers
• The time take in processing each message
• The total size of the vRealize Network Insight datastores
• The CPU and memory performance of vRealize Network Insight
• The disk performance of vRealize Network Insight

 
This allows the developers to efficiently detect bugs and issues, and also to monitor if the system is running healthy or not.

In addition, this is only a connection/data going out to the VMware cloud. This does not allow anyone to send any data or command back to the vRealize Network Insight system.
