Cluster monitoring

Cluster monitoring can view the basic information of the cluster, the resource consumption in the cluster and the change trend of resource consumption over a period of time.

Prerequisites

The cluster has insight-agent installed and the application is in running state.

Steps

  1. Go to the Insight product module.

  2. Select Infrastructure > Clusters from the left navigation pane. On this page, you can view the following information:

    1. Cluster List: Shows a list of clusters with the insight-agent installed. Click a specific cluster to view detailed information.
    2. Resource Overview: Provides statistics on the number of normal and total nodes and workloads across multiple clusters.
    3. Incidents: Displays the number of alerts generated in the current cluster.
    4. Resource Consumption: Shows the actual usage and total capacity of CPU, memory, and disk for the selected cluster.
    5. Metric Explanations: Describes the trends in CPU, memory, disk I/O, and network traffic for the selected cluster.

Metric Explanations

Metric Name Description
CPU Usage Rate The ratio of the actual CPU usage of all pod resources in the cluster to the total CPU capacity of all nodes.
CPU Allocation Rate The ratio of the sum of CPU requests of all pods in the cluster to the total CPU capacity of all nodes.
Memory Usage Rate The ratio of the actual memory usage of all pod resources in the cluster to the total memory capacity of all nodes.
Memory Allocation Rate The ratio of the sum of memory requests of all pods in the cluster to the total memory capacity of all nodes.
