Log Viewer

Tail and search logs across trading platform services.

Usage

• /logs - Tail all services (last 100 lines)
• /logs api - Tail specific service
• /logs --errors - Show only errors across all services
• /logs --search "order.*failed" - Search with regex
• /logs api --since 1h - Logs from last hour
• /logs --level error - Filter by log level
• /logs executor --follow - Live tail (follow mode)

Services

| Service | Container | Log Path | |---------|-----------|----------| | api | trading-api | stdout | | ui | trading-ui | stdout | | executor | trading-executor | stdout | | risk | trading-risk | stdout | | worker | trading-worker | stdout | | ml-server | ml-server | stdout | | market-ingest | market-ingest | stdout | | backtester | backtester | stdout |

Instructions

When this skill is invoked:

1. Parse arguments:

   • Service name: Filter to specific service
   • --errors: Filter level=error or level=ERROR
   • --search <pattern>: Grep with regex pattern
   • --since <duration>: Time filter (1h, 30m, 1d)
   • --level <level>: Filter by log level
   • --follow / -f: Live tail mode
   • --lines N / -n N: Number of lines (default 100)

2. For Docker Compose (dev):

   # Single service
   docker compose logs $SERVICE --tail $LINES $FOLLOW_FLAG
   
   # All services with grep
   docker compose logs --tail $LINES | grep -E "$PATTERN"
   
   # Errors only
   docker compose logs --tail 500 | grep -iE "error|exception|failed|traceback"
   

3. For Kubernetes (staging/prod):

   # Single pod
   kubectl logs -l app=$SERVICE -n trading --tail=$LINES $FOLLOW_FLAG
   
   # With stern for multi-pod
   stern $SERVICE -n trading --since $SINCE
   

4. Display formatted output:

   [09:31:05] api       INFO   Request: POST /orders
   [09:31:05] executor  INFO   Order received: abc123
   [09:31:06] executor  ERROR  Order failed: insufficient margin
   [09:31:06] risk      WARN   Margin utilization at 95%
   

5. For --errors, highlight and summarize:

   ERROR SUMMARY (last 1h)
   ─────────────────────────────────────────────────────────
   executor    12 errors   "insufficient margin" (8), "timeout" (4)
   api         3 errors    "validation failed" (3)
   ml-server   1 error     "model not found" (1)
   
   Most recent errors:
   [09:31:06] executor  Order failed: insufficient margin for AAPL x100
   [09:30:45] executor  Connection timeout to broker
   

6. For --search, show matches with context:

   • 2 lines before and after each match
   • Highlight matching text
   • Show total match count

7. Common log patterns to recognize:

   • Order lifecycle: submitted → acknowledged → filled/rejected
   • Errors: exceptions, tracebacks, failed operations
   • Performance: slow queries, timeouts
   • Security: auth failures, rate limits
