亚马逊 AWS - Cloudwatch。创建指标过滤器以创建警报

Question

我正在尝试在 cloudwatch 中设置警报。监视器应在日志中搜索特定字符串，例如：

在 Completed 状态下完成执行

您可以在下面找到在 cloudwatch 中找到的关于字符串的日志：

@MESSAGE:  {"log":"[25/Mar/2021:16:04:21 +0000] category=BACKEND severity=NOTICE msgID=414 msg=Backup task recurringBackupTask-20210325160000000 finished execution in the state Completed successfully\n","stream":"stdout","docker":{"container_id":"389f974c00190dec6cb9bdf4617618b989078fc503ecbe8aff50aad2c0703cb9"},"kubernetes":{"container_name":"ds","namespace_name":"users","pod_name":"ds-cts-2","container_image":"912682637080.dkr.ecr.eu-central-1.amazonaws.com/forgeops-v7/ds-cts@sha256:a7ef0afacbca756614228fbf4b518fc2c68d26ae67b6d013ef7ee13f053c97dd","container_image_id":"docker-pullable://912682637080.dkr.ecr.eu-central-1.amazonaws.com/forgeops-v7/ds-cts@sha256:a7ef0afacbca756614228fbf4b518fc2c68d26ae67b6d013ef7ee13f053c97dd","pod_id":"8c776a54-6ab2-4089-a80f-9e4b171d694d","host":"ip-10-6-23-94.eu-central-1.compute.internal","labels":{"affinity":"directory","app":"ds-cts","controller-revision-hash":"ds-cts-5cd69c68bf","tier":"ds","app_kubernetes_io/managed-by":"skaffold","app_kubernetes_io/name":"forgerock","linkerd_io/control-plane-ns":"linkerd","linkerd_io/proxy-statefulset":"ds-cts","linkerd_io/workload-ns":"users","skaffold_dev/run-id":"forgeops-int-7","statefulset_kubernetes_io/pod-name":"ds-cts-2"},"master_url":"https://172.20.0.1:443/api","namespace_id":"438bb425-03db-4193-b007-7517f46f12d3","namespace_labels":{"app_kubernetes_io/name":"users","app_kubernetes_io/part-of":"users"}}}

LOG:       [25/Mar/2021:16:04:21 +0000] category=BACKEND severity=NOTICE msgID=414 msg=Backup task recurringBackupTask-20210325160000000 finished execution in the state Completed successfully

所以我创建了这个指标：

{($.kubernetes.container_name= "ds") && ($.log = "finished execution in the state Completed successfully")}

创建警报并附加指标后，它似乎无法正常工作，因为它找不到字符串，因此始终处于警报状态

你有什么建议？度量是错误的吗？我已经尝试了很多组合，但似乎没有任何效果。

提前致谢

最好的 MC

Answer 1

试试这个：

{($.kubernetes.container_name= "ds") && ($.log = "*finished execution in the state Completed successfully*")}
