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
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>
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。
