Etherbeat

Welcome to Etherbeat. Etherbeat imports Ethereum blocks into Elasticsearch.

Ensure that this folder is at the following location: ${GOPATH}/src/github.com/dfb-chain/etherbeat

Getting Started with Etherbeat

Requirements

• Golang 1.7

Init Project

To get running with Etherbeat and also install the dependencies, run the following command:

make setup

It will create a clean git history for each major step. Note that you can always rewrite the history if you wish before pushing your changes.

To push Etherbeat in the git repository, run the following commands:

git remote set-url origin github.com/dfb-chain/etherbeat
git push origin master

For further development, check out the beat developer guide.

Build

To build the binary for Etherbeat run the command below. This will generate a binary in the same directory with the name etherbeat.

make

Using Docker

To build etherbeat Docker image

docker build -t <docker-repo>/etherbeat:latest .

Run

Config

Before starting, there are configurations user need to set

• eth_rpc_addr The RPC endpoint of the blockchain.
  • It can be RPC port on an Ethereum fullnode, for example http://1.2.3.4:8545
  • If you use Infra, it can also be your Infra project, for example https://<network>.infura.io/v3/YOUR-PROJECT-ID
• start_block The starting block to be imported. It must be below the current blockchain height. If the value is set to negative number, the import will start from the current blockchain height.

To run Etherbeat with debugging output enabled, run:

./etherbeat -c etherbeat.yml -e -d "*"

Run with Docker image

 docker run -e ELASTIC_HOST="<Elasticsearch_host>:9200" -e ETH_RPC_ADDR="<Ethereum RPC endpoint>" --rm -d <docker-repo>/etherbeat

Test

To test Etherbeat, run the following command:

make testsuite

alternatively:

make unit-tests
make system-tests
make integration-tests
make coverage-report

The test coverage is reported in the folder ./build/coverage/

Update

Each beat has a template for the mapping in elasticsearch and a documentation for the fields which is automatically generated based on fields.yml by running the following command.

make update

Cleanup

To clean Etherbeat source code, run the following command:

make fmt

To clean up the build directory and generated artifacts, run:

make clean

Clone

To clone Etherbeat from the git repository, run the following commands:

mkdir -p ${GOPATH}/src/github.com/dfb-chain/etherbeat
git clone github.com/dfb-chain/etherbeat ${GOPATH}/src/github.com/dfb-chain/etherbeat

For further development, check out the beat developer guide.

Packaging

The beat frameworks provides tools to crosscompile and package your beat for different platforms. This requires docker and vendoring as described above. To build packages of your beat, run the following command:

make release

This will fetch and create all images required for the build process. The whole process to finish can take several minutes.
