Error Logger

Structured JSON logging with correlation IDs for multi-service systems.

When to Use

Implementing logging infrastructure
Debugging failures across services
Tracing errors with correlation IDs
Adding error handling to operations
Reviewing logging patterns

Workflow

Step 1: Create Operation Context

Start operation with appropriate prefix (liq_, arb_, quo_, op_).

Step 2: Log with Context

Include correlation ID in all related log entries.

Step 3: Propagate Correlation ID

Pass via X-Correlation-ID header across services.

Log Format

{
  "timestamp": "2024-01-15T14:32:01.847Z",
  "level": "ERROR",
  "correlation_id": "liq_18d4f2a1_x7k9",
  "service": "rust-hotpath",
  "event_type": "TX_REVERT",
  "message": "Liquidation reverted",
  "context": {}
}

Correlation ID

Format:

{prefix}_{timestamp_hex}_{random}

Prefixes:

liq_

arb_

quo_

op_

Usage

const ctx = log.startOperation('liq');
log.error(ctx, 'TX_REVERT', 'Failed', { tx_hash, gas_used });

// Propagate via HTTP
headers: { 'X-Correlation-ID': ctx.correlation_id }

Log Levels

Level	Use For
ERROR	Operation failures
WARN	Retries, recoverable
INFO	Normal operations
DEBUG	Calculations
