/web3-o11y

Containerized app that uses Ethereum, Infura, and Web3.py library to automates data streaming to New Relic for querying and visualization

Primary LanguagePython

web3-o11y

use this repository to spin up a container that pulls data directly from Ethereum using Infura and Web3.py library. the data is then posted as custom events to the New Relic Metric API for querying and visualization.

Web3.py is a Python library for interacting with Ethereum: https://web3py.readthedocs.io/en/stable/
Infura is a service that provides a remote Ethereum node for free - no $$$ for my own node :')

getting started

  1. update the infra_url parameter in app.py with your own Infura API - you can create a free account and API key here
  2. update the account_id and insert_api_key parameters with your New Relic account number and Insert API Key

run locally

you can run this locally on your machine
docker build [OPTIONS] PATH | URL | - (i.e., docker build -t web3-repo .)

BUT❗

run as ECS task

I wanted to set it up as a scheduled task with ECS to generate a continual flow of Ethereum data to my New Relic dashboards:

  1. create Elastic Container Repository to store image
    aws ecr create-repository --repository-name web3-repo --region region

  2. tag the image with your repositoryUri
    docker tag web3-image aws_account_id.dkr.ecr.region.amazonaws.com/web3-repo

  3. run the aws ecr get-login-password command
    aws ecr get-login-password | docker login --username AWS --password-stdin aws_account_id.dkr.ecr.region.amazonaws.com

  4. push the image to Amazon ECR with the repositoryUri value from the earlier step. docker push aws_account_id.dkr.ecr.region.amazonaws.com/web3-repo

from there you can set up an EventBridge rule to run as a scheduled task (i.e., like a cronjob, run at certain times or intervals as desired)

review data via NRQL queries and dashboard

this will generate the following custom events:

  • walletBalance: contains the balance of wallets held by Snoop Dogg, Paris Hilton, Lindsay Lohan, Mark Cuban, and Serena Williams
  • blockStatz: contains the difficulty, gasLimit, gasUsed, miner, number, and size of latest block mined
  • gasPrice: contains the current price or fee per transaction on Ethereum in wei - one ether = 1,000,000,000,000,000,000 wei (10^18)

NRQL example queries

SELECT * FROM walletBalance
SELECT * FROM blockStatz
SELECT * FROM gasPrice

dashboard

find and replace the accountId parameter in the dashboard.json file and then import the json to New Relic to use this example dashboard image
