Datadog and Redis integration involves verifying Redis installation, installing the Datadog Agent, configuring it with a configuration file, restarting the Agent, and verifying the configuration. The integration allows for monitoring of key metrics, request traces, and logs from Redis, enabling real-time visibility into infrastructure or application performance issues and automated alerts to notify the right teams. After integrating Datadog with Redis, users can view detailed information on their Redis instance's performance in Datadog, including metrics such as latency and errors, as well as custom trace information and log entries, which provide insights into the execution of individual requests and server status. The integration also enables alerting on Redis metrics to notify teams of potential issues and provides end-to-end visibility into Redis infrastructure.
