Promviz

Promviz is an application that helps you visualize the traffic of your cluster from Prometheus data.

It has 2 components:

• Promviz: retrieves data from Prometheus servers, aggregates them and provides an API to get the graph data.

• Promviz-front: based on Netflix's vizceral to render traffic graph.

Features:

• Generates and renders traffic graph in realtime
• Able to replay from any time in the past
• Able to generate notices on node and connection from prom query
• Provides a sidecar application for k8s that watches config changes and reload Promviz server in runtime
• Fits with Istio's metrics
