Alethio EthStats Lite (network monitor)

Use Alethio EthStats Lite to have a live view of private network health by displaying real time and historical statistics about the network and nodes.

EthStats Lite supports in-memory persistence or using Redis to persist a fixed number of blocks (by default, 3000).

A full online version of EthStats for the Ethereum Mainnet is also available.


Static local ports 80 and 3000 are used in the example running EthStats Lite for a Hyperledger Besu Node


Statistics displayed by EthStats Lite include:

  • Nodes in the network. Metrics for nodes include:
    • Information about the last received block such as block number, block hash, transaction count, uncle count, block time and propagation time
    • Connected peers, whether the node is mining, hash rate, latency, and uptime
  • Charts for Block Time, Block Difficulty, Block Gas Limit, Block Uncles, Block Transactions, Block Gas Used, Block Propagation Histogram, and Top Miners
  • IP based geolocation overview
  • Node logs. Node logs display the data sent by a node
  • Block history. Block history provides the ability to go back in time and playback the block propagation through the nodes


EthStats Lite consists of:

  • Server. Consumes node data received from the client.

  • Client. A client must be started for each node in the network. The client extracts data from the node and sends it to the server

  • Dashboard. Dashboard displaying statistics.




EthStats Lite has a number of dependencies. Using Docker is the easiest way to use EthStats Lite with Besu.

The EthStats CLI, EthStats Network Server, and EthStats Network Dashboard documentation describes how to install EthStats Lite tools.

Running EthStats Lite for a Besu Node


This example describes how to run EthStats Lite for a single Besu node. To run EthStats Lite for a network of nodes, a client must be started for each node.

1. Server

Start the EthStats Lite server using in-memory persistence:

  1. Clone the server repository:

    git clone https://github.com/Alethio/ethstats-network-server.git
  2. Change into the /ethstats-network-server/docker/lite-mode/memory-persistence directory:

    cd ethstats-network-server/docker/lite-mode/memory-persistence
  3. Update the docker-compose.yml file to your Besu network ID:

     - NETWORK_ID=2018
     - NETWORK_NAME=mynetwork

    In this example we are using the dev Besu network with a network ID of 2018.

  4. Start the server using Docker compose:

    docker-compose up -d


A docker-compose file is provided in the ethstats-network-server/docker/lite-mode/redis-persistence directory to run the server using Redis to persist a fixed number of blocks (default is 3000).

2. Besu

Start Besu in development mode with WebSockets enabled:

docker run --rm -p 8546:8546 hyperledger/besu:latest --miner-enabled --miner-coinbase fe3b557e8fb62b89f4916b721be55ceb828dbd73 --rpc-http-cors-origins="all" --rpc-ws-enabled --network=dev

Where <besudata-path> is the volume to which the node data is saved.

3. Client

Start the client for the Besu node:

docker run -d --rm --name ethstats-client --net host alethio/ethstats-cli --register --account-email <email> --node-name <node_name> --server-url http://localhost:3000 --client-url ws://


  • --server-url specifies your server. The default is the server that consumes data for the Ethereum MainNet.
  • --register specifies the registration of the Besu node is done automatically with the specified <email> and <node_name>. Registering the node is only required the first time the client is started for the node.
  • --client-url specifies the WebSockets URL for the Besu node.

4. Dashboard

To display EthStats Lite dashboard, open http://localhost in your browser.

Default HTTP port

We are using the default HTTP port (80) to run EthStats Lite. The Lite Block Explorer example uses port 8080. You can then run both at the same time.

To change the port, update the docker-compose.yml file:


Update the first 80 to the required port:


Stopping and Cleaning Up Resources

When you’ve finished running EthStats Lite:

  1. Stop Besu using Ctrl+C.

  2. Stop EthStats Lite server and remove containers and volumes:

    docker-compose down -v
  3. Stop EthStats Lite client:

    docker stop ethstats-client


    The client container is automatically removed because we used the --rm option.
