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
Architecture

are available on Docker Hub.
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
- promviz: http://localhost:9091/graph
- prometheus: http://localhost:9090/graph
- mock-metric: http://localhost:30001/metrics
