4.4. 验证是否应用了 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
