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.

• 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

If you are using Helm, the simplest way to install is using the charts in helm directory with

helm install --name promviz ./helm/promviz
helm install --name promviz-front ./helm/promviz-front

Docker images of both promviz and promviz-front are available on Docker Hub.

• nghialv2607/promviz
• mjhddevlion/promviz-front

I have already prepared 2 examples and put them in the example directory.

You can try it by going to that directory and run

docker-compose -f simple-compose.yaml up --build

or

docker-compose -f full-compose.yaml up --build

Then checkout each service at:

• promviz-front: http://localhost:8080/graph
• promviz: http://localhost:9091/graph
• prometheus: http://localhost:9090/graph
• mock-metric: http://localhost:30001/metrics
