How can I use CloudWatch Logs to monitor delivery of Amazon SNS text messages?

We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better. First, create and subscribe to an SNS topic. When you create a CloudWatch alarm, you can add this SNS topic to send an email notification when the alarm changes state. Alternatively, if you plan to create your CloudWatch alarm using the AWS Management Console, you can skip this procedure because you can create the topic through the Create Alarm Wizard.

First, create a topic, then subscribe to it. You can optionally publish a test message to the topic.

Choose Create topic.Amazon SNS provides topics for high-throughput, push-based, many-to-many messaging. Amazon SNS uses cross availability zone message storage to provide high message durability.

All messages published to Amazon SNS are stored redundantly across multiple geographically separated servers and data centers. Amazon SNS is a fully managed service, taking care of the heavy lifting related to capacity planning, provisioning, monitoring, and patching.

The service is designed to handle high-throughput, bursty traffic patterns. Moreover, there is no upfront cost, and no need to acquire, install, configure, or upgrade messaging software.

With Amazon SNS message filtering, subscribing endpoints receive only the messages of interest, instead of all messages published to the topic. Amazon CloudWatch gives visibility into your filtering activity, and AWS CloudFormation enables you to deploy subscription filter policies in an automated and secure manner. Amazon SNS topic owners can keep sensitive data secure by setting topic policies that restrict who can publish and subscribe to a topic. Amazon SNS enables message filtering and fanout to a large number of subscribers, including serverless functions, queues, and distributed systems.

The alarm performs one or more actions based on the value of the metric or expression relative to a threshold over a number of time periods. A composite alarm includes a rule expression that takes into account the alarm states of other alarms that you have created. The alarms specified in a composite alarm's rule expression can include metric alarms and other composite alarms. Using composite alarms can reduce alarm noise. You can create multiple metric alarms, and also create a composite alarm and set up alerts only for the composite alarm.

You can add alarms to CloudWatch dashboards and monitor them visually. When an alarm is on a dashboard, it turns red when it is in the ALARM state, making it easier for you to monitor its status proactively.

Alarms invoke actions for sustained state changes only. CloudWatch alarms don't invoke actions simply because they are in a particular state, the state must have changed and been maintained for a specified number of periods. After an alarm invokes an action due to a change in state, its subsequent behavior depends on the type of action that you have associated with the alarm. For Amazon EC2 Auto Scaling actions, the alarm continues to invoke the action for every period that the alarm remains in the new state.

For Amazon SNS notifications, no additional actions are invoked. CloudWatch doesn't test or validate the actions that you specify, nor does it detect any Amazon EC2 Auto Scaling or Amazon SNS errors resulting from an attempt to invoke nonexistent actions.

Make sure that your alarm actions exist. OK — The metric or expression is within the defined threshold. When you create an alarm, you specify three settings to enable CloudWatch to evaluate when to change the alarm state:.

Period is the length of time to evaluate the metric or expression to create each individual data point for an alarm. It is expressed in seconds. If you choose one minute as the period, there is one data point every minute. Evaluation Period is the number of the most recent periods, or data points, to evaluate when determining alarm state.You can then view logs of successful and failed message deliveries.

Last updated: On the Edit text messaging preferences page, expand Delivery status logging - optional. Under the IAM roles section, choose Create new service role. Choose Create new roles. On the IAM console permission request page, choose Allow. Choose Save changes. For Phone numberenter the phone number where you want to receive your test SMS message.

For Messageenter the message body of your test SMS message. Choose Publish message. The phone number you entered should receive the test SMS message. Check the provider response logs Open the CloudWatch console. In the left navigation pane, choose Logs.

You can use CloudWatch to detect anomalous behavior in your environments, set alarms, visualize logs and metrics side by side, take automated actions, troubleshoot issues, and discover insights to keep your applications running smoothly.

Modern applications such as those running on microservices architectures generate large volumes of data in the form of metrics, logs, and events. Amazon CloudWatch enables you to set alarms and automate actions based on either predefined thresholds, or on machine learning algorithms that identify anomalous behavior in your metrics.

For example, it can start Amazon EC2 Auto Scaling automatically, or stop an instance to reduce billing overages. To optimize performance and resource utilization, you need a unified operational view, real-time granular data, and historical reference. CloudWatch provides automatic dashboards, data with 1-second granularity, and up to 15 months of metrics storage and retention.

To take action quickly, you can set up automated actions to notify you if an alarm is triggered and automatically start auto scaling, for example, to help reduce mean-time-to-resolution. You can also dive deep and analyze your metrics, logs, and traces, to better understand how to improve application performance. Monitor key metrics and logs, visualize your application and infrastructure stack, create alarms, and correlate metrics and logs to understand and resolve root cause of performance issues in your AWS resources.

CloudWatch helps you correlate, visualize, and analyze metrics and logs, so you can act quickly to resolve issues, and combine them with trace data from AWS X-Ray for end-to-end observability. You can also analyze user requests to help speed up troubleshooting and debugging, and reduce overall mean-time-to-resolution MTTR. CloudWatch alarms watch your metric values against thresholds that either you specify, or that CloudWatch creates for you using machine learning models to detect anomalous behavior.

If an alarm is triggered, CloudWatch can take action automatically to enable Amazon EC2 Auto Scaling or stop an instance, for example, so you can automate capacity and resource planning.If you've got a moment, please tell us what we did right so we can do more of it.

We're sorry we let you down. If you've got a moment, please tell us how we can make the documentation better. For example, you can set an alarm to send you an email notification if a specified threshold is met for an Amazon SNS metric, such as NumberOfNotificationsFailed. These metrics are gathered on all topics that meet the CloudWatch guidelines for being active. A topic is considered active by CloudWatch for up to six hours from the last activity that is, any API call on the topic.

Sign in to the CloudWatch console. On the All metrics tab, choose SNSand then choose one of the following dimensions:. To view more detail, choose a specific item. For example, if you choose Topic Metrics and then choose NumberOfMessagesPublishedthe average number of published Amazon SNS messages for a five-minute period throughout the time range of 6 hours is displayed. CloudWatch also allows you to set alarms when a threshold is met for a metric.

For example, you could set an alarm for the metric, NumberOfNotificationsFailedso that when your specified threshold number is met within the sampling period, then an email notification would be sent to inform you of the event. Choose Alarmsand then choose the Create Alarm button. This launches the Create Alarm wizard. Scroll through the Amazon SNS metrics to locate the metric you want to place an alarm on. Select the metric to create an alarm on and choose Continue. Fill in the NameDescriptionThresholdand Time values for the metric, and then choose Continue.

Choose Alarm as the alarm state. If you choose Create New Email Topicyou can set the name and email addresses for a new topic. This list will be saved and appear in the drop-down box for future alarms. Choose Continue. Emails are sent only when the alarm enters an alarm state. If this alarm state change happens before the email addresses are verified, they will not receive a notification.

If you need to make any changes, you can use the Edit links on the right. Once you are satisfied, choose Create Alarm. The number of messages successfully delivered from your Amazon SNS topics to subscribing endpoints. For a delivery attempt to succeed, the endpoint's subscription must accept the message. A subscription accepts a message if a. If the subscription rejects the message, the delivery attempt isn't counted for this metric.

For all other endpoints, the count increases by 1 when the message fails to deliver regardless of the number of attempts.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Although the alert works, and the SNS config seems correct to me, the lambda function is never invoked. The lambda function works, and I can send it test data via the aws console resulting in a message posted to Slack. However, if I manually add the SNS topic as an "event source" on the lambda function, it is invoked when the alarm fires and Slack messages are posted. Am I misunderstanding how to connect a cloud watch alarm to a lambda function?

Or is there a small detail I am missing?

If this approach cannot work, and the only way to connect a lambda function to a cloud watch alarm is to add the SNS topic as an "event source", what is the appropriate way to do that via AWS CloudFormation Templates? I don't see an obvious way to modify an existing resource such as a fixed lambda function. Being said that, I also had the same problem as you, following the steps mentioned in the blueprint, I do not get the alarms until I manually add the SNS topic as an "event source" on the lambda function.

Bonus: similar question with the same answer: AWS Lambda scheduled event source via cloudformation. CloudWatch Scheduled event now has Lambda an a native target.

Make sure you give the SNS topic permission to invoke your Lambda function. The CloudFormation for the permission will look something like this:. Learn more. Asked 4 years, 3 months ago. Active 2 years, 3 months ago.

The load balancer is created with a correct-looking cloud watch alarm: The alarm appears to be configured to send alerts to the correct SNS topic: There is an SNS subscription to that topic, with the lambda function as it's endpoint: Alarms are triggered and messages sent to the correct topic when the alarm fires: But the lambda function is never invoked: However, if I manually add the SNS topic as an "event source" on the lambda function, it is invoked when the alarm fires and Slack messages are posted.
