Structured Logging
Use JSON logs with levels and contexts. Popular Node.js choice: winston. Include request IDs, shard IDs, and command names for traceability.
const winston = require('winston');
const logger = winston.createLogger({
level: 'info',
format: winston.format.json(),
transports: [new winston.transports.Console()]
});
logger.info({ event: 'command', name: interaction.commandName, userId: interaction.user.id });
Error Tracking
Use a service like Sentry or open-source alternatives to capture exceptions and traces. Redact tokens and PII.
Uptime and Health
- Expose a lightweight health endpoint on your web server
- Monitor process restarts and memory usage
- Create on-call alerts for repeated gateway reconnects
Dashboards
Ship logs to a centralized store (Elastic/Loki) and create panels: command latency, error rate, shard status, rate limit hits.
Alerting
Set thresholds (e.g., >2% error rate over 5m) to page maintainers. Route alerts to a private Discord channel via webhook.
