Datadog provides comprehensive visibility into HashiCorp Vault's health and performance by integrating with over 850 technologies, offering customizable dashboards, log management, and automated alerting. To get started, users can set up Datadog's Vault integration using a client token or unauthenticated access to the metrics endpoint, explore Vault metrics in out-of-the-box dashboards, collect and analyze Vault logs, create automated alerts for security threats, and track long-term performance trends. The Datadog Agent collects metrics and distributed traces from Vault's `/sys/metrics` endpoint, as well as resource metrics from servers, and sends them to Datadog for retention at full granularity for 15 months. With Datadog, users can automatically detect potential security threats, correlate data across their stack, and gain deeper insights into their infrastructure and applications.
