The A10 Harmony Controller and A10 Thunder appliances collect per-app metrics, consolidates the analytics, and correlates them in a central repository. This provides Layer 4Layer 7 application visibility so that administrators can quickly troubleshoot and resolve network and security problems.

What’s New in A10 Harmony Controller v4.1

  • Pre-loaded with A10’s Thunder ADC services and self-service Harmony App for Thunder SSLi.
  • Analytics history increased to 12 months. The longer history allows NetOps and SecOps to investigate older events, like client access logs and traffic analytics data.
  • In the case of three-nodes controller deployment, we provide redundancy with Multi-master High Availability.

Harmony Applications Overview

The Harmony Controller 4.1 release comes with a modular application framework that provides centralized application visibility and management platform for secure L4-7 services.
