4.6. 为 OpenShift Logging 组件配置 CPU 和内存限值

您可以根据需要配置每个 OpenShift Logging 组件的 CPU 和内存限值。

4.6.1. 配置 CPU 和内存限值

OpenShift Logging 组件允许对 CPU 和内存限值进行调整。

流程

  1. 编辑 openshift-logging 项目中的 ClusterLogging 自定义资源(CR):

    $ oc -n openshift-logging edit ClusterLogging instance
    apiVersion: "logging.openshift.io/v1"
    kind: "ClusterLogging"
    metadata:
      name: "instance"
      namespace: openshift-logging
    
    ...
    
    spec:
      managementState: "Managed"
      logStore:
        type: "elasticsearch"
        elasticsearch:
          nodeCount: 3
          resources: 1
            limits:
              memory: 16Gi
            requests:
              cpu: 200m
              memory: 16Gi
          storage:
            storageClassName: "gp2"
            size: "200G"
          redundancyPolicy: "SingleRedundancy"
      visualization:
        type: "kibana"
        kibana:
          resources: 2
            limits:
              memory: 1Gi
            requests:
              cpu: 500m
              memory: 1Gi
          proxy:
            resources: 3
              limits:
                memory: 100Mi
              requests:
                cpu: 100m
                memory: 100Mi
          replicas: 2
      collection:
        logs:
          type: "fluentd"
          fluentd:
            resources: 4
              limits:
                memory: 736Mi
              requests:
                cpu: 200m
                memory: 736Mi

    根据需要为日志 visualizer 指定 CPU 和内存限值和请求。
    4
    根据需要指定日志收集器的 CPU 和内存限值及请求。
