Thumbnail icon

Amazon Simple Notification Service (SNS) is a pub/sub messaging and mobile notifications service for coordinating the delivery of messages to subscribing endpoints and clients.

The Sumo Logic App for Amazon SNS collects CloudTrail logs and CloudWatch metrics provides a unified logs and metrics app that provides insights into the operations and utilization of your SNS service. The preconfigured dashboards help you monitor the key metrics by application, platform, region, and topic name, view the SNS events for activities, and help you plan the capacity of your SNS service.

Log and Metrics Types​

The Sumo Logic App for Amazon SNS uses:

  • SNS CloudWatch Metrics. For details, see here.

  • SNS operations using AWS CloudTrail. For details, see here.

Collecting Logs and Metrics for the Amazon SNS App​

Collecting Metrics for Amazon SNS​

  1. Configure a Hosted Collector.
  2. Configure an Amazon CloudWatch Source for Metrics or AWS Kinesis Firehose for Metrics Source (Recommended).

  3. Click Save.

Collecting Amazon SNS Events using CloudTrail​

  1. To your Hosted Collector, add an AWS CloudTrail Source.

Installing the Amazon SNS App​

Now that you have set up collection for Amazon SNS, install the Sumo Logic App to use the pre-configured searches and dashboards that provide visibility into your environment for real-time analysis of overall usage.

To install the app:

Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.

  1. From the App Catalog, search for and select the app.
  2. To install the app, click Add to Library and complete the following fields.
    • App Name. You can retain the existing name, or enter a name of your choice for the app.

    • Enter the SNS Metrics Source.
    • Select either of these options for the SNS CloudTrail Log Source.
      • Choose Source Category, and select a source category from the list.

      • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. Example: (_sourceCategory=MyCategory).

    • Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
  3. Click Add to Library.

Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization. See Welcome to the New Library for information on working with the library in the new UI.

Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but with a bit of time, you'll see full graphs and maps.
