导出日志

本页面适用于基础架构运维者。

配置 fluent-bit 附加输出

除了在集群中运行的 Loki 之外，您还可以将日志导出到其他目标位置。请参阅支持的平台列表。此设置可以按集群配置或进行全局配置。

全局配置

1. 在 anthos-management-center 命名空间中创建一个带有 logmon: system_logs 标签的 configmap。额外的输出配置与 fluent-bit 输出插件具有相同的语法，应添加到 output.conf 文件中的 data 字段下。请参阅示例配置文件。

   apiVersion: v1
   kind: ConfigMap
   metadata:
     # The name should match the configmap name specified in step 3.
     name: <customized-system-logs-fluent-bit-output-config>
     # Don't change the namespace
     namespace: anthos-management-center
     labels:
       # This label is required.
       logmon: system_logs
   data:
     # The file name must be output.conf
     output.conf: |
       # Add a customized fluent-bit output plugin configuration here
   

2. 运行以下命令，在命令行编辑器中打开您的 Observability 自定义资源：

   kubectl --kubeconfig=ADMIN_OIDC_KUBECONFIG -n anthos-management-center edit observability default
   

3. 在 Observability 自定义资源中的 spec/logging 字段下添加 additionalSink 字段。

   apiVersion: managementcenter.anthos.cloud.google.com/v1alpha1
   kind: Observability
   metadata:
     # Don't change the name
     name: default
     # Don't change the namespace
     namespace: anthos-management-center
   spec:
     enabled: true
     logging:
       additionalSink:
         fluentbitConfigMaps:
         # The name should match the configmap name created in step 1.
         - "<customized-system-logs-fluent-bit-output-config>"
         # Scheme: []v1.VolumeMount. Add volumeMounts if necessary
         volumeMounts:
         - ...
         - ...
         # Scheme: []v1.Volume. Add volumes if necessary
         volumes:
         - ...
         - ...
   

4. 如需保存对 Observability 自定义资源所做的更改，请保存并退出命令行编辑器。

按集群配置

1. 通过将集群名称添加到 Observability 自定义资源中的 spec/logging/additionalSink/clusterSelector/exclude 列表，可以从全局配置中排除集群。

   apiVersion: managementcenter.anthos.cloud.google.com/v1alpha1
   kind: Observability
   metadata:
     # Don't change the name
     name: default
     # Don't change the namespace
     namespace: anthos-management-center
   spec:
     enabled: true
     logging:
       additionalSink:
         clusterSelector:
           exclude:
           - cluster-name
         ...
   

2. 在 kube-system 命名空间中创建一个带有 logmon: system_logs 标签的 configmap。额外的输出配置与 fluent-bit 输出插件具有相同的语法，应添加到 output.conf 文件中的 data 字段下。请参阅示例配置文件。

   apiVersion: v1
   kind: ConfigMap
   metadata:
     # The name should match the configmap name specified in step 3.
     name: <customized-system-logs-fluent-bit-output-config>
     # Don't change the namespace
     namespace: kube-system
     labels:
       # This label is required.
       logmon: system_logs
   data:
     # The file name must be output.conf
     output.conf: |
       # Add a customized fluent-bit output plugin configuration here
   

3. 运行以下命令，在命令行编辑器中打开您的 LogMon 自定义资源：

   kubectl --kubeconfig=ADMIN_OIDC_KUBECONFIG -n kube-system edit logmon logmon-default
   

4. 在 LogMon 自定义资源中的 spec/system_logs/outputs 字段下添加 additionalOutput 字段。

   apiVersion: addons.gke.io/v1alpha1
   kind: Logmon
   metadata:
     # Don't change the name
     name: logmon-default
     # Don't change the namespace
     namespace: kube-system
   spec:
     system_logs:
       outputs:
         additionalOutput:
           fluentbitConfigmaps:
           # The name should match the configmap name created in step 1.
           - "<customized-system-logs-fluent-bit-output-config>"
           # Scheme: []v1.VolumeMount. Add volumeMounts if necessary
           volumeMounts:
           - ...
           - ...
           # Scheme: []v1.Volume. Add volumes if necessary
           volumes:
           - ...
           - ...
   

5. 如需保存对 LogMon 自定义资源所做的更改，请保存并退出命令行编辑器。
