Checking Node Status

To understand and monitor the status of your Bee node, bee-js provides a set of helpful methods. In this guide, we'll walk through how to retrieve and log the data needed to give a complete overview of your node's current status.

Requirements​

To use the example scripts below, you need:

  • An instance of the Bee class from bee-js initialized using the API endpoint of a currently operating Bee node.

1. Node Health and Readiness​

Use these to read the health and readiness endpoints, the same values that container orchestration tools like Kubernetes rely on.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function checkHealthAndReadiness() {
  const health = await bee.status.getHealth()
  const readiness = await bee.status.getReadiness()

  console.log('Health:', health)
  console.log('Readiness:', readiness)
}

checkHealthAndReadiness()

Output:

Health: { apiVersion: '7.3.0', version: '2.5.0-5ec231ba', status: 'ok' }
Readiness: { apiVersion: '7.3.0', version: '2.5.0-5ec231ba', status: 'ready' }

2. Get Node Topology​

Use this to inspect how many peers you're connected to, and the state of your neighborhood.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function checkTopology() {
  const topology = await bee.connectivity.getTopology()

  console.log('Topology:', topology)
}

checkTopology()

Output: (Bins 1 - 30 omitted from bins result)

Topology: {
  baseAddr: '1e2054bec3e681aeb0b365a1f9a574a03782176bd3ec0bcf810ebcaf551e4070',
  population: 5619,
  connected: 135,
  timestamp: '2025-03-26T07:54:05.921263981Z',
  nnLowWatermark: 3,
  depth: 10,
  reachability: 'Public',
  networkAvailability: 'Available',
  bins: {
    bin_0: {
      population: 2714,
      connected: 16,
      connectedPeers: [Array],
      disconnectedPeers: [Array]
    },
    ...
    bin_31: {
      population: 0,
      connected: 0,
      connectedPeers: [],
      disconnectedPeers: []
    }
  }
}

3. Get Node Addresses​

This will give you the overlay address, underlay addresses, and Ethereum address associated with your Bee node. The Ethereum address uses the Ethereum format, but it belongs to a Gnosis Chain account rather than to mainnet Ethereum.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function checkAddresses() {
  const addresses = await bee.connectivity.getNodeAddresses()

  console.log('Node Addresses:')
  console.log('Overlay:', addresses.overlay.toHex())
  console.log('Ethereum:', addresses.ethereum.toHex())
  console.log('Public Key:', addresses.publicKey.toHex())
  console.log('PSS Public Key:', addresses.pssPublicKey.toHex())
  console.log('Underlay:', addresses.underlay)
}

checkAddresses()

Output:

Node Addresses:
Overlay: 1e2054bec3e681aeb0b365a1f9a574a03782176bd3ec0bcf810ebcaf551e4070

Underlay: [
  '/ip4/127.0.0.1/tcp/1634/p2p/QmcpSJPHuuQYRgDkNfwziihVcpuVteoNxePvfzaJyp9z7j',
  '/ip4/172.17.0.2/tcp/1634/p2p/QmcpSJPHuuQYRgDkNfwziihVcpuVteoNxePvfzaJyp9z7j',
  '/ip6/::1/tcp/1634/p2p/QmcpSJPHuuQYRgDkNfwziihVcpuVteoNxePvfzaJyp9z7j'
]

4. Get Version and API Compatibility​

Use these methods to check your node's version number and the API version number, and to check whether the API version is supported by bee-js.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function checkVersions() {
  const versions = await bee.status.getVersions()
  const isSupported = await bee.status.isSupportedApiVersion()

  console.log('Node Versions:', versions)
  console.log('Is Supported API Version:', isSupported)
}

checkVersions()

Output:

Node Versions: {
  supportedBeeVersion: '2.4.0-390a402e',
  supportedBeeApiVersion: '7.2.0',
  beeVersion: '2.5.0-5ec231ba',
  beeApiVersion: '7.3.0'
}
Is Supported API Version: true

5. Get Node Info​

This provides general information such as node mode (e.g., full, light), and whether chequebook and SWAP are enabled.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function getNodeInfo() {
  const info = await bee.status.getNodeInfo()

  console.log('Node Info:', info)
}

getNodeInfo()

Output:

Node Info: { beeMode: 'light', chequebookEnabled: true, swapEnabled: true }

6. Get Chain State​

Shows blockchain-related info such as the current price for storage.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function getChainState() {
  const state = await bee.status.getChainState()

  console.log('Chain State:', state)
}

getChainState()

Output:

Chain State: {
  block: 39230575,
  chainTip: 39230580,
  totalAmount: '204168626286',
  currentPrice: 41699
}

7. Get Reserve State​

This tells you about your node’s local reserve size and storage metrics.

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function getReserveState() {
  const reserveState = await bee.status.getReserveState()

  console.log('Reserve State:', reserveState)
}

getReserveState()

Output:

Reserve State: { commitment: 17360879616, radius: 13, storageRadius: 0 }

Run All Checks Together​

You can combine all of the above into one function to quickly inspect the full status of your node:

import { Bee } from '@ethersphere/bee-js'

const bee = new Bee('http://localhost:1633')

async function checkHealthAndReadiness() {
  const health = await bee.status.getHealth()
  const readiness = await bee.status.getReadiness()

  console.log('Health:', health)
  console.log('Readiness:', readiness)
}

async function checkTopology() {
  const topology = await bee.connectivity.getTopology()

  console.log('Topology:', topology)
}

async function checkAddresses() {
  const addresses = await bee.connectivity.getNodeAddresses()

  console.log('Node Addresses:')
  console.log('Overlay:', addresses.overlay.toHex())
  console.log('Ethereum:', addresses.ethereum.toHex())
  console.log('Public Key:', addresses.publicKey.toHex())
  console.log('PSS Public Key:', addresses.pssPublicKey.toHex())
  console.log('Underlay:', addresses.underlay)
}

async function checkVersions() {
  const versions = await bee.status.getVersions()
  const isSupported = await bee.status.isSupportedApiVersion()

  console.log('Node Versions:', versions)
  console.log('Is Supported API Version:', isSupported)
}

async function getNodeInfo() {
  const info = await bee.status.getNodeInfo()

  console.log('Node Info:', info)
}

async function getChainState() {
  const state = await bee.status.getChainState()

  console.log('Chain State:', state)
}

async function getReserveState() {
  const reserveState = await bee.status.getReserveState()

  console.log('Reserve State:', reserveState)
}

async function checkNodeStatus() {
  console.log('\n\n=== Node Health and Readiness ===')
  await checkHealthAndReadiness()

  console.log('\n\n=== Node Topology ===')
  await checkTopology()

  console.log('\n\n=== Node Addresses ===')
  await checkAddresses()

  console.log('\n\n=== Version and API Compatibility ===')
  await checkVersions()

  console.log('\n\n=== Node Info ===')
  await getNodeInfo()

  console.log('\n\n=== Chain State ===')
  await getChainState()

  console.log('\n\n=== Reserve State ===')
  await getReserveState()
}
