Fleet monitoring of Alibaba Cloud Distributed Cloud Container Platform (ACK One) is based on the Managed Service for Prometheus metric type. It provides a dashboard for Fleet monitoring, including core component (API server and etcd) monitoring and GitOps monitoring (such as Argo CD monitoring and ECI Pod disk monitoring). This helps you to understand the real-time running of the Fleet and the Argo CD it hosts. This topic describes how to enable Fleet monitoring.
Background information
Fleet Cluster is the administrator of multiple Kubernetes clusters. Fleet monitoring ensures the stability and efficiency of the multi-cluster management. ACK One also hosts Argo CD in the Fleet for multi-cluster GitOps management. As the number of applications increases, pods that are related to Argo CD may encounter issues such as Out of Memory (OOM) and Out of Diskspace (OOD). Fleet monitoring of ACK One can help you decide how much resources these pods need. It can also help you decide when to upgrade the instance specification and how to troubleshoot the exception.
