Introduction
Exporting data from CloudWatch to CSV is a crucial task for in-depth analysis and reporting. This process can seem daunting without the right guidance.
In this guide, we will walk you through the steps required to efficiently export your CloudWatch data to a CSV file. You'll learn to streamline this process using practical tips and tools.
Additionally, we will explore how Sourcetable lets you analyze your exported data with AI in a simple-to-use spreadsheet.
Exporting AWS CloudWatch Data to CSV
- Exporting AWS CloudWatch data to CSV format involves using API calls or scripts to extract and convert metrics data. AWS CloudWatch does not offer a built-in feature for direct CSV export, but various methods and tools are available to achieve this.
- You can extract metrics from AWS CloudWatch using its API. Writing a program to call these APIs allows you to receive and format the metrics. The `aws cloudwatch get-metric-statistics` command is commonly used to obtain specific metrics for services such as EC2. The command output can be piped to `jq` for conversion into CSV format.
- A recommended approach is to use a Python script that retrieves CloudWatch metrics and converts them into CSV files. The script requires specifying the AWS service whose metrics need to be retrieved, with optional arguments for the AWS Region and credentials. By default, the script generates and stores the CSV file in the same directory where it is executed.
- Several projects can simplify exporting CloudWatch metrics to CSV. Tools like `mogproject/cloudwatch-dump` and `romgapuz/awsmetric2csv` offer utilities to extract metrics and save them in CSV format. Additionally, visualization tools like Prometheus and Grafana can be used to export CloudWatch metrics into CSV.
- The Python script and various tools support exporting metrics for services such as AWS Lambda, Amazon EC2, Application Load Balancer, Network Load Balancer, and API Gateway. However, they do not collect metrics for Amazon EBS volumes or Amazon Aurora by default.
- To export CloudWatch metrics to CSV, follow these steps: 1. Call the CloudWatch APIs to retrieve the metrics.2. Use a program or script to format the metrics.3. Store the formatted data in a CSV file.Using the AWS CLI and `jq`, you can achieve this by converting JSON output into CSV.
- Although CloudWatch dashboards provide visualization, exporting these visualizations directly to CSV is not supported. Instead, integrate with tools like Prometheus and Grafana to visualize and export metrics into CSV format. These tools enhance readability and usability of the exported data.

How to Export CloudWatch Data to CSV
Overview
Exporting Amazon CloudWatch data to CSV format enhances readability and eases data analysis. Follow these detailed instructions to export CloudWatch metrics and logs data to organized CSV files.
Exporting CloudWatch Metrics to CSV
You can use a Python script to export CloudWatch metrics data to a CSV file. The script retrieves metrics data from CloudWatch and converts it into a comma-separated values (CSV) format for improved readability.
The script requires the AWS service whose metrics you want to retrieve as a mandatory argument. Optionally, you can specify the AWS Region and AWS credential profile. If these optional arguments are not provided, the script uses the default Region and profile configured for your workstation.
The script generates a CSV file and stores it in the same directory where the script is located. The script supports metrics for AWS Lambda, EC2, RDS, Application Load Balancer, Network Load Balancer, and API Gateway. Note that Amazon Aurora is not supported, and to collect EBS volume metrics, you must modify the metrics.yaml file.
Exporting CloudWatch Logs to CSV
Similarly, a Python script can be utilized to export CloudWatch logs to a CSV file. The script retrieves logs data from CloudWatch and converts this data into CSV format. This process facilitates easier data reading and analysis.
As with metrics, the script takes the AWS service to retrieve logs from as a required argument. You can optionally provide the AWS Region and AWS credential profile. If these are not specified, the script uses the default settings configured for the workstation.
Exporting CloudWatch Logs Data to Amazon S3
CloudWatch Logs data can be exported to an Amazon S3 bucket. Ensure that the S3 bucket is in the same region as the log group and that it has the appropriate bucket policy allowing CloudWatch Logs to write to it.
You can perform cross-account exports, allowing you to export log data to an S3 bucket in a different account, or same-account exports, exporting data to a bucket within the same account. CloudWatch Logs recommends using a dedicated bucket for this purpose, though you can use an existing bucket. The bucket owner retains full permissions on all exported objects.
For added security, the S3 bucket can be encrypted with Server-Side Encryption with AWS Key Management Service (SSE-KMS).
