dubbo_exporter

Exposing dubbo statistics via HTTP for Prometheus consumption

Requirements

Running Kubernetes cluster with Helm/Tiller installed
JDK 1.8+, Maven 3.5, Docker, and Helm client for building this project

Build

Execute the following script to build:

git clone https://github.com/gmemcc/dubbo_exporter.git
cd dubbo_exporter
mvn clean package

Docker image with repository docker.gmem.cc/prometheus/dubbo_exporter will be generated, you may modify configuration of dockerfile-maven-plugin in pom.xml to change this default repository, and run

mvn dockerfile:push

to push the image to your private registry.

Packaged helm chart will be populated into target/charts directory.

Deploy

Execute the following script to deploy dubbo_exporter on your kubernetes cluster:

mvn bash:run

Also, you can invoke helm cli manually:

helm delete dubbo-exporter --purge
helm install target/charts/dubbo_exporter.tgz --name=dubbo-exporter --set zookeeper.host=zk,zookeeper.port=2181
