wanjunlei benjaminhuo 感谢两位回复解答，发现目前的监控比较简单，我们计划是自定义一些更贴近业务的监控项，要怎么把3.0自带的prometheus暴露到外部访问呢，控制台上不能配置外网网关

        tzghost 你需要编辑下面的 svc, 不是 operator 的 svc

        kubectl -n kubesphere-monitoring-system get svc prometheus-k8s
NAME             TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
prometheus-k8s   NodePort   10.233.9.200   <none>        9090:31193/TCP   19d
            6 天 后

            benjaminhuo alertmanager-main的配置不能修改吗？发现修改replicas为1或者编辑配置模板等操作，配置会还原。另外alertmanager-main里的alertmanager.yaml加密了，调整这个文件的配置，要怎么处理？

              给prometheus-k8s-rulefiles-0添加配置项也被还原了

              11 天 后

              这些都要编辑 crd ，不能直接编辑工作负载或者configmap：

              # 调整 Alertmanager replica 
kubectl -n kubesphere-monitoring-system edit alertmanagers.monitoring.coreos.com main
# 调整 Alertmanager 配置 , 需要把内容拷贝出来 base64 解码，改完后再base64编码写进去
kubectl -n kubesphere-monitoring-system edit secrets alertmanager-main
# 修改 rule 也要改crd
kubectl -n kubesphere-monitoring-system edit prometheusrules.monitoring.coreos.com prometheus-k8s-rules
                5 天 后

                调整后正常了，但遇到了新的问题，现在一直报ContainerBackoff，但这个POD我已经删除重建了，还是一直有这个告警，这是什么问题？benjaminhuo

                          看下alertmanager有没有notification-manager-operator-6958786cd6-qmck2的告警：
                          curl alertmanager-main.kubesphere-monitoring-system.svc:9093/api/v2/alerts?filter=pod=notification-manager-operator-6958786cd6-qmck2查看，或者暴露出kubesphere-monitoring-system/alertmanager-main服务的9093端口，访问端口对应页面查看

                              notification-manager-operator 是个 deployment，删了pod 当然还会重新创建
                              另外这个组件是从 Alertmanager 接收微信、slack告警必须的，不能删
                              你删它的意图是什么？

                                    benjaminhuo 是因为notification-manager-operator-6958786cd6-qmck2这个POD一直有ContainerBackoff的告警，所以尝试删除重建。按理说删除重建后原来的POD已经不存在了，告警应该会恢复的，但这个告警还一直有，比较奇怪

                                      tzghost 看下kubesphere-logging-system/ks-events-ruler负载的日志是否有异常
