Heroku's Logplex streams logs from applications, system events, and API actions into an ephemeral 1,500-line buffer that expires quickly. Developers can view logs via CLI commands like `heroku logs --tail` or the dashboard, but built-in logging lacks long-term retention, search, and analytics. Best practices include writing structured JSON to stdout, using correlation IDs, and protecting sensitive data. For production monitoring, forward logs to external services like Honeybadger Insights using log drains to enable search, alerting, dashboards, and unified error tracking alongside log data.
