Monitor Consul health and performance with Datadog

Consul is a distributed configuration and service-discovery tool that enables dynamic service discovery and reacting to real-time changes in service availability. It uses a distributed client-server architecture based on the Raft consensus algorithm, providing fault-tolerance with strong data consistency. Datadog integration allows monitoring of Consul health and availability across clusters. Key features include built-in health checks for both node and service levels, latency metrics to track leader and follower interactions, cluster health metrics, event monitoring, tagging for scalable monitoring solutions, and custom alerts based on metric thresholds.
