Docker setup

Grafana dashboard

export GF_SECURITY_ADMIN_USER=<YOUR_ADMIN_USER> # change this if you want to have a different admin user name, default is admin
export GF_SECURITY_ADMIN_PASSWORD=<YOUR_ADMIN_PASSWORD> # change this if you want to have a different admin password, default is admin
export WEB3_PROVIDER=<YOUR_WEB3_PROVIDER> # if this is set, it overrides Infura, and instead a custom url is used as the web3 provider
export ETHERSCAN_TOKEN=<YOUR_ETHERSCAN_TOKEN> # this needs to be set
export EXPLORER=<EXPLORER> # optional, default to: https://api.etherscan.io/api
export SLEEP_SECONDS=<YOUR_SLEEP_SECONDS> # if this is set, the exporters will wait the given amount of time between subsequent invocations to your web3 provider.
