Enabling Monitoring for Multi-Cloud Clusters
This section describes how to enable monitoring for multi-cloud clusters.
Prerequisites
A multi-cloud cluster has been registered with UCS. For details, see Overview.
Preparing the Network Environment
The data access mode of a multi-cloud cluster supports public network access, which is flexible, inexpensive, and easy. The cluster must be able to access public networks. If network quality is not a concern and simpler access is preferred, public network access is a good choice.
This option is only available for clusters that can access public networks.
Enabling Monitoring
- Log in to the UCS console. In the navigation pane, choose Container Intelligent Analysis.
- Select a fleet or a cluster not in the fleet, and click Enable Monitoring.
Figure 1 Selecting a fleet or a cluster not in the fleet
- Select a multi-cloud cluster.
- Click Next: Configure Connection to complete the network settings.
- Data Access: Select Public access.
- Data Reported To: Select the region where data is reported.
- Project: If the IAM project function is enabled, you also need to select a project.
- Complete metric collection settings.
Specifications
- Deployment Mode: The Agent and Server modes are supported. The add-on deployed in Agent mode occupies fewer cluster resources and provides Prometheus metric collection for clusters. However, it does not support the HPA and health diagnosis functions based on custom Prometheus statements. The add-on deployed in Server mode provides Prometheus metric collection for clusters and supports the HPA and health diagnosis functions based on custom Prometheus statements. This mode depends on the PVC and consumes a large amount of memory.
- Add-on Specifications: If Deployment Mode is set to Agent, the default add-on specifications are used. If Deployment Mode is set to Server, the add-on specifications include Demo (≤ 100 containers), Small (≤ 2,000 containers), Medium (≤ 5,000 containers), and Large (> 5,000 containers). Different specifications have different requirements on cluster resources, such as CPUs and memory. For details about the resource quotas of different add-on specifications, see Resource Quota Requirements of Different Specifications..
Parameters
- Interconnection Mode: Currently, only AOM can be interconnected.
- AOM Instance: Container monitoring reports metrics to AOM in a unified manner. Therefore, you need to select an AOM Prometheus for CCE instance. The default metrics are collected for free but custom metrics are billed by AOM. For details, see AOM Billing.
- Collection Period: period for Prometheus to collect and report metrics. The value ranges from 10 to 60 seconds. The default value is 15 seconds.
- Storage: used to temporarily store Prometheus data. This parameter is mandatory when Deployment Mode is set to Server.
- Storage Type: Multi-cloud clusters support emptyDir and local-storage.
If emptyDir is used, Prometheus data will be stored in the pod. Ensure that the storage volume mounted to the container on the node scheduled by prometheus-server-0 is no less than the entered capacity.
If local-storage is used, the monitoring namespace (if it does not exist) and PVs and PVCs of the local-storage type will be created in your cluster. Ensure that the entered directory exists on the specified node and the path capacity is sufficient.
- Capacity: capacity specified when a PVC is created or the maximum storage limit when the pod storage is selected.
- Storage Type: Multi-cloud clusters support emptyDir and local-storage.
For details about the add-on, see kube-prometheus-stack.
- Click Confirm. The Container Insights > Clusters page is displayed. The access status of the cluster is Installing.
After monitoring is enabled for the cluster, metrics such as the CPU usage and CPU allocation rate of the cluster are displayed in the list, indicating that the cluster is monitored by CIA.
