重命名 Amazon CloudWatch 警报

Question

我正在尝试组织大量 CloudWatch 警报以实现可维护性，并且 Web 控制台在编辑时将名称字段灰显。是否有另一种方法（最好是可编写脚本的）来更新 CloudWatch 警报的名称？除了简单的可执行脚本之外，我更喜欢不需要任何编程的解决方案。

Answer 1

不幸的是，目前看来这是不可能的。

Answer 2

这是我们暂时用来执行此操作的脚本：

import sys
import boto


def rename_alarm(alarm_name, new_alarm_name):
    conn = boto.connect_cloudwatch()

    def get_alarm():
        alarms = conn.describe_alarms(alarm_names=[alarm_name])
        if not alarms:
            raise Exception("Alarm '%s' not found" % alarm_name)
        return alarms[0]

    alarm = get_alarm()

    # work around boto comparison serialization issue
    # https://github.com/boto/boto/issues/1311
    alarm.comparison = alarm._cmp_map.get(alarm.comparison)

    alarm.name = new_alarm_name
    conn.update_alarm(alarm)

    # update actually creates a new alarm because the name has changed, so
    # we have to manually delete the old one
    get_alarm().delete()

if __name__ == '__main__':
    alarm_name, new_alarm_name = sys.argv[1:3]

    rename_alarm(alarm_name, new_alarm_name)

它假设您要么在具有允许执行此操作的角色的 ec2 实例上，要么您有一个包含凭据的 ~/.boto 文件。手动添加你的很容易。
