+# Promviz [![PRs Welcome](https://img.shields.io/badge/PRs-welcome-brightgreen.svg?style=flat)](http://makeapullrequest.com)
+
+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](https://github.com/mjhd-devlion/promviz-front): based on Netfix'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 Promviz server in runtime
+- Fits with [Istio](https://istio.io)'s metrics

+
+## Architecture
+
+![](https://github.com/nghialv/promviz/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 promviz ./helm/promviz
+helm install --name promviz-front ./helm/promviz-front
+```
+
+#### Docker images
+
+Docker images of both `promviz` and `promviz-front` are available on Docker Hub.
+
+- [nghialv2607/promviz](https://hub.docker.com/r/nghialv2607/promviz)
+- [mjhddevlion/promviz-front](https://hub.docker.com/r/mjhddevlion/promviz-front)
+
+## Example
+
+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](http://localhost:8080/)
+- promviz: [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)
