bitcoind-exporter

Bitcoind metrics Prometheus exporter.

bitcoind-exporter is compatible with most bitcoin forks.

Produce blockchain, wallet and addresses metrics. Most relevant metrics are:

• wallet total balance
• wallet version
• if the wallet is unlocked
• available (spendable) balance for each managed addresses (and watched addresses)
• best block time and index
• ...

Usage

Edit the .env environment file to suit your needs and run:

npm start

bitcoind-exporter uses the bitcoind JSON-RPC API under the hood and need those credentials:

rpcuser=test
rpcpassword=1cf98b57-5i09-4fa1-9c07-2e28cb2cb47b

Usage with other wallets

The following environment variables are available, that should be enough for any bitcoin forks:

ticker=DASH
rpcuser=test
rpcpassword=1cf98b57-5i09-4fa1-9c07-2e28cb2cb47b
rpchost=127.0.0.1
rpcport=9999
rpcscheme=http

Docker

Using environment variables:

docker run -d --restart always --name my-exporter -p 9439:9439 -e "rpcuser=myrpcuser" -e "rpcpassword=myrpcpassword" -e "rpchost=my-wallet" --link my-wallet lepetitbloc/bitcoind-exporter

Using a .env file:

docker run -d --restart always --name my-exporter -p 9439:9439 -v /path/to/my/conf:/app/.env --link my-wallet lepetitbloc/bitcoind-exporter

An easy hack could be to directly use your wallet conf to feed your exporter env:

docker run --name my-exporter -p 9439:9439 -v /path/to/my/conf:/app/.env --link my-wallet lepetitbloc/bitcoind-exporter
