Health Check Integration

The node-health-check backend can monitor wallet balances and send Slack alerts when balances drop below a threshold. This is configured on the health check side (typically in the rpc-load-balancer deployment).

Configuration

Set these environment variables in the health check .env, matching each RPC_URL_{i} endpoint:

Variable	Format	Description
RPC_WALLET_AUTH_{i}	user:password	BasicAuth credentials matching WALLET_API_BASICAUTH on the orchestra node
RPC_MIN_BALANCE_KAS_{i}	1.0	Minimum balance threshold in KAS (default: 1.0)

Example (in rpc-load-balancer .env):

RPC_URL_0=https://stage-7.igralabs.com:8545
RPC_NAME_0=stage-7
RPC_WALLET_AUTH_0=admin:YOUR_PASSWORD
RPC_MIN_BALANCE_KAS_0=1.0

The health check derives the wallet API URL from the RPC endpoint's domain: https://stage-7.igralabs.com/internal/wallets.

Or via config.toml:

[[rpc_endpoints]]
node_id = "stage-7"
url = "https://stage-7.igralabs.com:8545"
wallet_api_auth = "admin:YOUR_PASSWORD"
min_balance_kas = 1.0

Slack Alerts

When configured, the health check Slack messages include a wallet balance section:

--- Wallet Balances ---
  stage-7 - 30,885.95 KAS total, 5/20 wallets funded
  Wallet #5: 0.0000 KAS (kaspatest:qq5gmkr6...)
  Wallet #6: 0.0000 KAS (kaspatest:qrdvkqgw...)
