Retina

Overview

Retina is a cloud-agnostic, open-source Kubernetes network observability platform that provides a centralized hub for monitoring application health, network health, and security. It provides actionable insights to cluster network administrators, cluster security administrators, and DevOps engineers navigating DevOps, SecOps, and compliance use cases.

Retina collects customizable telemetry, which can be exported to multiple storage options (such as Prometheus, Azure Monitor, and other vendors) and visualized in a variety of ways (like Grafana, Azure Log Analytics, and other vendors).

Features

eBPF-based Network Observability platform for Kubernetes workloads.
On-Demand and Configurable.
Actionable, industry-standard Prometheus metrics.
Streamlined Packet Captures for deep dives.
Cloud-agnostic, supporting multiple OS (like Linux, Windows, Azure Linux).
