To initiate an exception request to enable this integration for your organization, email [support@ddog-gov.com](mailto:support@ddog-gov.com). {% /alert %} {% /callout %} ## Overview{% #overview %} [Alibaba Cloud Tair](https://www.alibabacloud.com/help/en/tair/product-overview/what-is-tair) is an in-memory database service compatible with the Redis protocol, offering persistent memory-optimized instances and a KV cache for large language model applications. Use this integration to monitor cache hit rates, memory and CPU usage, connection counts, and token throughput across your Tair instances. ## Setup{% #setup %} ### Installation{% #installation %} After you set up the [Alibaba Cloud](https://docs.datadoghq.com/integrations/alibaba_cloud.md) integration, ensure that the Tair service is included in your Alibaba Cloud monitoring configuration. ##
