Question

我创建了一个闹钟，之后想删除它... boto 2的documentation没有显示如何执行此操作。

有任何帮助吗？感谢

如果要删除警报，则所需的API为KafkaTableSource source = Kafka08JsonTableSource.builder()// set Kafka topic .forTopic("alerting") // set Kafka consumer properties .withKafkaProperties(getKafkaProperties()) // set Table schema .withSchema(TableSchema.builder() .field("tenant", Types.STRING()) .field("message", Types.STRING()) .field("frequency", Types.LONG()) .field("timestamp", Types.SQL_TIMESTAMP()).build()) .failOnMissingField(true) .withRowtimeAttribute( // "timestamp" is rowtime attribute "timestamp", // value of "timestamp" is extracted from existing field with same name new ExistingField("timestamp"), // values of "timestamp" are at most out-of-order by 30 seconds new BoundedOutOfOrderTimestamps(TimeUnit.DAYS.toMillis(1))) .build(); //register the alerting topic as kafka tEnv.registerTableSource("kafka", source); Table results = tEnv.sqlQuery("SELECT tenant, message, SUM(frequency) " + "FROM kafka " + "GROUP BY HOP(rowtime, INTERVAL '1' SECOND, INTERVAL '5' SECOND), tenant, message"); tEnv.toAppendStream(results, Row.class).print();。您在问题中的链接提到了它（搜索DeleteAlarms）。

另外，boto 3是推荐使用的版本，以下是您需要的API：https://boto3.readthedocs.io/en/latest/reference/services/cloudwatch.html#CloudWatch.Client.delete_alarms

如何使用Boto 3：

进行操作的示例

delete_alarms

Boto 2示例：

import boto3
client = boto3.client('cloudwatch')
client.delete_alarms(AlarmNames=['SomeAlarmName'])

如果你不知道这个名字，你可以得到一个警报列表（对于boto 2和3都是一样的）：

import boto
client = boto.connect_cloudwatch()
client.delete_alarms('SomeAlarmName')

Answer 2

你应该使用Boto3。但如果你与Boto2联系在一起，那么：

import boto
cw = boto.connect_cloudwatch()
alarms= cw.describe_alarms()
for alarm in alarms:
  print alarm.name

检查是否列出了要删除的警报。然后使用该名称：

cw.delete_alarms([<alarm_to_be_deleted>])

使用boto 2获取CloudWatch的Alarm对象
