+
+* Forked from - https://github.com/nghialv/promviz and https://github.com/mjhd-devlion/promviz-front 
+
+Vistio is an application that helps you visualize the traffic of your cluster from Prometheus data.
+
+It has 2 components:
+
+- Vistio-API: retrieves data from Prometheus servers, aggregates them and provides an API to get the graph data.
+
+- Vistio-Web: Forked from [Promviz-front](https://github.com/mjhd-devlion/promviz-front): based on Netflix's [vizceral](https://github.com/Netflix/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 Vistio server in runtime
+- Fits with [Istio](https://istio.io)'s metrics

+
+## Architecture
+
+![](https://github.com/nmnellis/vistio/blob/master/documentation/architecture.png)
+
+## Install
+
+#### Helm chart
+
+If you are using [Helm](https://helm.sh), the simplest way to install is using the charts in `helm` directory with
+
+```
+helm install --name vistio ./helm/vistio
+```
+
+#### Docker images
+
+Docker images of both `vistio-api` and `vistio-web` are available on Docker Hub.
+
+- [nmnellis/vistio-api](https://hub.docker.com/r/nmnellis/vistio-api)
+- [nmnellis/vistio-web](https://hub.docker.com/r/nmnellis/vistio-web)
+
+## Example
+
+An Istio example is in the `/example` directory
+
+You can try it by going to that directory and run
+
+```
+docker-compose up --build
+```
+
+Then checkout each service at:
+- promviz-front: [http://localhost:8080/graph](http://localhost:8080/)
+- vistio: [http://localhost:9091/graph](http://localhost:9091/graph)
+- prometheus: [http://localhost:9090/graph](http://localhost:9090/graph)
+- mock-metric: [http://localhost:30001/metrics](http://localhost:30001/metrics)
+
+## Configuration
+
+See [configuration.md](https://github.com/nmnellis/vistio/blob/master/documentation/configuration.md) in documentation directory.
+
+## Deploy with Istio Bookinfo 
+
+1. Deploy Vistio
+
+2. Get Vistio host and port.
+```sh
+export VISTIO_HOST=$(kubectl get po -l app=vistio-web -n default -o 'jsonpath={.items[0].status.hostIP}')
+export VISTIO_PORT=$(kubectl get service vistio-web -o jsonpath='{.spec.ports[?(@.name=="http")].nodePort}')
+export VISTIO_URL=$VISTIO_HOST:$VISTIO_PORT
+```
