The text discusses the integration of Datadog with Azure Key Vault to help users monitor the expiration of credentials stored within the Vault, such as SSH keys, API keys, and database passwords. This integration generates automatic alerts when a credential's expiration date approaches, allowing users to renew them in advance and avoid application downtime. It provides an example of how an engineer might use this feature to prevent losing access to essential environments during testing. The document also explains how Datadog handles certificate and key expiration as a single event and describes how it manages missing permission events, which notify users when Datadog lacks access to certain Key Vaults. Overall, the feature aims to ensure uninterrupted access to critical Azure resources by proactively managing credential expirations and permissions, with guidance on setting up the necessary permissions for Azure App Registrations.
