Collect and Analyze Your Application’s Log Data

The Collect and Analyze Application Log Data template provides you with a complete setup to gather and process logs for multiple AWS regions. It combines products such as CloudWatch Logs, Kinesis Data Streams, Kinesis Data Firehose, and OpenSearch Service. 

The following is what occurs when you use this template: 

• Your application logs are gathered using CloudWatch Logs. 

• Such logs are piped through filters to pass only significant information. 

• Kinesis Data Firehose and Kinesis Data Streams transfer these logs in real time. 

• They're being stored in Amazon S3 and routed to OpenSearch Service where you can search, visualize, and analyze them. 

This all happens across several AWS regions. This is to say that you don't have to manually gather logs from various accounts or locations. It all converges in one location for you to look at and take action on.
 

Why is this template a game changer? 

Log management is typically time-wasting. You might need to log into various accounts, open various services, and download files just to diagnose one mistake. It is so easy to lose your way when logs are spread around. 

With this template: 

• You have centralized log gathering. Everything is in one location. 

• Logs are dealt with in real time. You hear what's going on as it occurs. 

• Subscription filters ensure you only retain valuable data. 

• OpenSearch Service simplifies searching and analyzing with dashboards and visualizations. 

Rather than spending time switching between regions and services, you have instant access to clean, structured logs. This saves time, enables quicker troubleshooting, and enhances the health and security of your app overall. 
 

Who can use this template, and when? 

This template is perfect for anyone operating applications on AWS and would like more visibility into what's going on inside them. 

You will require this if: 

• You support applications across multiple AWS regions. 

• You're seeking real-time monitoring of logs to identify errors early on. 

• You would like to log data visualization so that you can see trends more easily. 

• You are fed up with looking through scattered logs and desire one system. 

It is optimal to apply this template beforehand, even when issues are not yet occurring. Having it set up ahead of time is such that when an issue does arise, you already have the tools ready to review your logs and make corrections as quickly as possible. 
 

What are the main components of the template? 

Here's a quick overview of the components of this setup and what they do: 

• CloudWatch Logs – Logs your app's logs. 

• Subscription Filter – Removes excess log data. 

• Kinesis Data Streams – Streams logs in real-time. 

• Kinesis Data Firehose – Pipes logs to S3 and OpenSearch Service. 

• AWS Lambda – Processes and converts logs as they come in. 

• OpenSearch Service – Allows you to search and visualize your logs. 

• Amazon S3 – Saves logs for long-term access and backup. 

• Multiple AWS Regions – Captures logs from various locations. 

• Subscription Destination – Sends logs to the correct destination. 

• IAM Role – Manages safe access to log information. 

• Metric Filters – Monitors your logs for key performance metrics. 

• CloudTrail – Logs security and auditing information. 

• SNS Notification – Notifies you when something significant happens. 

Each component plays a distinct role. Combined, they form a system that simplifies log management and is more dependable.

Summary 

As applications expand, so does the volume of log data. Without a functioning system in place, you can lose precious time and find yourself scratching your head trying to see what is going on. This template eliminates that with an easy method of aggregating and analyzing all your logs by region. It leverages tools such as CloudWatch Logs, Kinesis Data Streams, Kinesis Data Firehose, and OpenSearch Service to simplify log management and make it more efficient. You can view your logs in real time, exclude what you don't want, keep them secure in S3, and review them through OpenSearch dashboards. 
 

By setting up this template, you enhance the monitoring, minimize troubleshooting time, and ensure your application is secure and in top working order. If you value application log analysis, log management tools, real-time log monitoring, log data visualization, and centralized log collection, this template is the ideal place to begin for you.
