Alibaba Cloud Managed Service for Prometheus allows you to install and configure Memcached exporters. Managed Service for Prometheus also provides out-of-the-box dashboards that you can use to monitor Memcached instances. This topic describes how to install and configure a Memcached exporter in Managed Service for Prometheus.
Prerequisites
A Prometheus instance for Container Service is created. For more information, see Create a Prometheus instance to monitor an ACK cluster.
Background information
Managed Service for Prometheus allows you to monitor self-managed Memcached instances deployed in Container Service for Kubernetes (ACK) clusters, ACK Serverless clusters, or registered Kubernetes clusters.
Limits
You can install the exporter only for Prometheus for Container Service instances.
