4.4. 验证是否应用了 Tuned 配置集

使用这个流程检查在每个节点上应用了哪些 Tuned 配置集。

流程

  1. 检查每个节点上运行的 Tuned Pod:

    $ oc get pods -n openshift-cluster-node-tuning-operator -o wide

    输出示例

    NAME                                            READY   STATUS    RESTARTS   AGE    IP             NODE                                         NOMINATED NODE   READINESS GATES
    cluster-node-tuning-operator-599489d4f7-k4hw4   1/1     Running   0          6d2h   10.129.0.76    ip-10-0-145-113.eu-west-3.compute.internal   <none>           <none>
    tuned-2jkzp                                     1/1     Running   1          6d3h   10.0.145.113   ip-10-0-145-113.eu-west-3.compute.internal   <none>           <none>
    tuned-g9mkx                                     1/1     Running   1          6d3h   10.0.147.108   ip-10-0-147-108.eu-west-3.compute.internal   <none>           <none>
    tuned-kbxsh                                     1/1     Running   1          6d3h   10.0.132.143   ip-10-0-132-143.eu-west-3.compute.internal   <none>           <none>
    tuned-kn9x6                                     1/1     Running   1          6d3h   10.0.163.177   ip-10-0-163-177.eu-west-3.compute.internal   <none>           <none>
    tuned-vvxwx                                     1/1     Running   1          6d3h   10.0.131.87    ip-10-0-131-87.eu-west-3.compute.internal    <none>           <none>
    tuned-zqrwq                                     1/1     Running   1          6d3h   10.0.161.51    ip-10-0-161-51.eu-west-3.compute.internal    <none>           <none>

  2. 提取从每个 Pod 应用的配置集,并将它们与上一个列表中匹配:

    $ for p in `oc get pods -n openshift-cluster-node-tuning-operator -l openshift-app=tuned -o=jsonpath='{range .items[*]}{.metadata.name} {end}'`; do printf "\n*** $p ***\n" ; oc logs pod/$p -n openshift-cluster-node-tuning-operator | grep applied; done

    输出示例

自定义性能优化规格的自定义配置集只是一个技术预览功能。红帽产品服务等级协议 (SLA) 不支持技术预览功能,且可能无法完成。红帽不推荐在生产环境中使用它们。这些技术预览功能可以使用户提早试用新的功能,并有机会在开发阶段提供反馈意见。
