system_health - JSON-RPC Method

Description

Returns basic health telemetry from an Enjin Matrix node including whether it is syncing, the number of peers it is connected to, and whether it expects to have peers. This call is lightweight and safe to poll for infrastructure monitoring.

Parameters

This method does not take any parameters.

Returns

Field	Type	Description
peers	number	Number of peers currently connected
isSyncing	boolean	Indicates if the node is still catching up
shouldHavePeers	boolean	Whether the node configuration requires peers

Request Example

{
  "jsonrpc": "2.0",
  "method": "system_health",
  "params": [],
  "id": 1
}

Response Example

{
  "jsonrpc": "2.0",
  "result": {
    "peers": 21,
    "isSyncing": false,
    "shouldHavePeers": true
  },
  "id": 1
}

Code Examples

cURL

curl https://api-enjin-matrixchain.n.dwellir.com/YOUR_API_KEY \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "system_health",
    "params": [],

  }'

JavaScript (Node.js)

async function checkHealth() {
  const response = await fetch('https://api-enjin-matrixchain.n.dwellir.com/YOUR_API_KEY', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
      jsonrpc: '2.0',
      method: 'system_health',
      params: [],
      id: 1
    })
  });

  const { result } = await response.json();
  console.log(`Peers: ${result.peers}`);
  console.log(`Syncing: ${result.isSyncing}`);
}

Python (requests)

import json
import requests

payload = {
    "jsonrpc": "2.0",
    "method": "system_health",
    "params": [],
    "id": 1,
}

health = requests.post(
    "https://api-enjin-matrixchain.n.dwellir.com/YOUR_API_KEY",
    headers={"Content-Type": "application/json"},
    data=json.dumps(payload),
    timeout=10,
).json()["result"]

print(f"Peers: {health['peers']} | Syncing: {health['isSyncing']}")

Monitoring Tips

• Set alerts if isSyncing flips to true for production nodes to catch stalled peers early.
• Track peers over time to validate network connectivity after redeployments or firewall changes.
• Combine with system_syncState for more granular progress reporting during initial syncs.
