How to test

• Make sure the node.js installed on the system
• Change to the project folder and run the following command

npm install

• Start elastic search docker container first

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.6.2

• Run the following command to start the server

npm start

Docker development

• Run Usage Stats Handler, Elasticsearch and Grafana

docker-compose up --build --abort-on-container-exit --remove-orphans --force-recreate

• Note: At times elasticsearch hangs on startup, to fix this either run it again and/or run

docker system prune

Testing with Elasticsearch

• Running test/opennms-test.http in Intellij to test or using the curl to post report
• Using the following command to verify the report saved

curl -v -X POST --location "http://localhost:9200/opennms_log/_count?pretty"
curl -v -X POST --location "http://localhost:9200/opennms_system/_count?pretty"

• Visualise the grafana graph update with new values on a refresh

Running in the production environment
