英文:
Disabling cloud watch alarm actions with lambda
问题
我正在尝试使用 Lambda 函数禁用 CloudWatch 告警操作，如以下文章提供的方式："https://medium.com/geekculture/enable-or-disable-aws-alarms-at-given-intervals-d2f867aa9aa4"。
然而，在执行过程中，我遇到了超时问题。生成的 HTTP 请求没有返回任何错误。
代码如下：
import logging
import os
import boto3
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
def disable_alarms(alarm_names):
try:
logger.debug(f'禁用告警')
disable_alarm = client.disable_alarm_actions(AlarmNames=alarm_names)
return disable_alarm
except Exception as e:
logger.debug(f'禁用告警时出错: {e}')
def enable_alarms(alarm_names):
try:
logger.info(f'启用告警: {alarm_names}')
enable_alarm = client.enable_alarm_actions(AlarmNames=alarm_names)
return enable_alarm
except Exception as e:
logger.debug(f'启用告警时出错: {alarm_names}, {e}')
def lambda_handler(event, context):
logger.info(f'## 事件: {event}')
global client
client = boto3.client('cloudwatch')
global list_of_alarm_arns
list_of_alarm_names = ['HealthAlarm']
logger.info(f'发送到函数禁用')
# 启用告警
# enable_alarms(list_of_alarm_names)
# 禁用告警
disable_alarms(list_of_alarm_names)
return {
'statusCode': 200,
}
要禁用的是名为 "HealthAlarm" 的告警操作。

I am trying to disable the cloudwatch alarm actions using lambda function as provided by following article "https://medium.com/geekculture/enable-or-disable-aws-alarms-at-given-intervals-d2f867aa9aa4".
However i am facing timeouts during it's execution. The http request for generated does not return any error.
The code is as below:
import logging
import os
import boto3
logger = logging.getLogger()
logger.setLevel(logging.DEBUG)
def disable_alarms(alarm_names):
try:
logger.debug(f'Disabling alarms')
disable_alarm = client.disable_alarm_actions(AlarmNames=alarm_names)
return disable_alarm
except Exception as e:
logger.debug(f'Error while disabling alarms:, {e}')
def enable_alarms(alarm_names):
try:
logger.info(f'Enabling alarms: {alarm_names}')
enable_alarm = client.enable_alarm_actions(AlarmNames=alarm_names)
return enable_alarm
except Exception as e:
logger.debug(f'Error while enable alarms: {alarm_names}, {e}')
def lambda_handler(event, context):
logger.info(f'## EVENT: {event}')
global client
client = boto3.client('cloudwatch')
global list_of_alarm_arns
list_of_alarm_names = ['HealthAlarm']
logger.info(f'Sending To Function Disable')
#enable_alarms(list_of_alarm_names)
disable_alarms(list_of_alarm_names)
return {
'statusCode': 200,
}
The HealthAlarm existing actions is to be disabled.

问题出在与VPC连接的Lambda函数上，正如JohnRotenstein所提到的那样。一旦断开连接，函数就可以正常运行，而没有任何超时问题。
英文:
The issue was with the lambda function being connected to the VPC as @JohnRotenstein mentioned. On disconnecting the same, the function ran without any timeouts.

尝试检查Lambda执行角色：它需要CloudWatch权限来执行警报上的操作。

英文:
Try to check Lambda Execution role: it needs Cloudwatch permissions to performs actions on alarms.
