Log Drains are a new feature introduced by ZEIT, allowing users to collect logs from their deployments and forward them to archival, search, and alerting services using HTTPS, HTTP, TLS, and TCP protocols. The feature supports three types of log drains: JSON, NDJSON, and Syslog, as well as integrations with LogDNA and Datadog. With Log Drains, users can persistently store logs, create alerts based on logging patterns, generate metrics and graphs from logs data, and easily integrate their deployments with third-party services. The feature is available in the ZEIT Integrations marketplace, where users can install and configure integrations to forward their logs to services such as LogDNA, Logflare, and Datadog.
