ETL monitoring using Amazon Managed Grafana

As organizations increasingly rely on data-driven decisions, ensuring the reliability and performance of ETL (Extract, Transform, Load) processes becomes mission-critical. Monitoring these pipelines helps identify bottlenecks, detect failures, and optimize resource usage. Amazon Managed Grafana is a powerful visualization service that enables seamless monitoring of ETL workflows by integrating with AWS data sources and third-party tools. In this blog, we’ll explore how to use Amazon Managed Grafana for ETL monitoring and why it's an excellent choice for modern data engineering teams.


What Is Amazon Managed Grafana?

Amazon Managed Grafana is a fully managed service from AWS that allows you to visualize operational data from multiple sources, including CloudWatch, Prometheus, and Amazon OpenSearch. It’s based on the open-source Grafana project and eliminates the need for manual setup, patching, and infrastructure management.

Amazon Managed Grafana provides secure, scalable, and collaborative dashboarding for monitoring your infrastructure, applications, and data pipelines like ETL processes.


Why Monitor ETL Pipelines?

ETL processes involve multiple stages where failures or performance issues can occur:

  • Extract: Data not being pulled from source systems.
  • Transform: Errors or delays in data transformation logic.
  • Load: Issues while writing data into a target data store like a data warehouse or data lake.

Monitoring ensures:

  • Timely identification of errors or anomalies.
  • Improved performance through historical analysis.
  • Better resource utilization and SLA adherence.


How Amazon Managed Grafana Helps

Amazon Managed Grafana supports monitoring ETL pipelines by connecting to a wide range of data sources where ETL logs and metrics are stored. Here’s how you can leverage it:

1. Connect to Data Sources

Grafana connects with:

  • Amazon CloudWatch: For ETL logs and metrics generated by AWS Glue, Lambda, Step Functions, or custom scripts.
  • Amazon OpenSearch Service: For log analytics.
  • Amazon Timestream or Prometheus: For time-series metrics.
  • Third-party tools: Such as Apache Airflow, DBT, or Jenkins that are used to orchestrate ETL processes.


2. Build Dashboards

Create intuitive dashboards to visualize:

  • ETL job duration and success/failure status.
  • Resource usage (memory, CPU, I/O).
  • Number of records processed per stage.
  • Error logs and retry counts.

Example metrics:

Glue job run times.

Lambda execution errors.

S3 data ingestion counts.

Redshift data load success rates.


3. Set Alerts and Notifications

Grafana supports custom alerts and can integrate with Amazon SNS, Slack, PagerDuty, or email. You can set alerts for conditions such as:

  • A job that hasn’t run in the last 24 hours.
  • An unusually high failure rate.
  • Delays beyond the expected ETL window.


4. Enable Collaboration

Using Amazon Managed Grafana’s role-based access control (RBAC), teams can share dashboards with stakeholders across engineering, data, and operations without exposing sensitive data.

Benefits of Using Amazon Managed Grafana

Fully managed: No infrastructure maintenance or updates.

Scalable and secure: Integrated with AWS IAM and SSO.

Real-time visibility: Immediate insights into pipeline health.

Customizable dashboards: Tailor views for different roles and stakeholders.


Conclusion

Monitoring ETL processes is essential for data integrity, performance, and operational efficiency. Amazon Managed Grafana provides a flexible, scalable, and secure way to visualize and track your ETL workflows in real time. By integrating with AWS and third-party tools, it simplifies pipeline observability, helps catch issues early, and enhances the overall reliability of your data ecosystem. Whether you’re managing ETL with AWS Glue, Apache Airflow, or custom scripts, Grafana is a key tool in your monitoring toolkit.

How to Use Tosca's Test Configuration Parameters

Tosca by Tricentis is a powerful model-based test automation tool widely used in enterprise environments for end-to-end testing. One of its most useful features is Test Configuration Parameters (TCPs), which provide flexibility and control in managing test execution. TCPs enable testers to create reusable test cases by passing dynamic values without hardcoding them. This significantly enhances test maintenance, scalability, and efficiency. In this blog, we’ll explore what Test Configuration Parameters are, how to create and use them, and the best practices to follow when working with TCPs in Tosca. What Are Test Configuration Parameters? Test Configuration Parameters are custom-defined key-value pairs that can be associated with test cases, test case folders, or execution lists in Tosca. They help manage configuration data such as environment URLs, browser types, credentials, or any other variable data that may differ across test runs. By using TCPs, you can avoid duplicating test case...

Using Hibernate ORM for Fullstack Java Data Management

In the world of fullstack Java development, managing data efficiently and seamlessly across the application is critical. One of the most powerful tools in the Java ecosystem for handling database operations is Hibernate ORM (Object-Relational Mapping). Hibernate simplifies the interaction between Java applications and relational databases, reducing boilerplate code and improving maintainability. This blog explores how Hibernate ORM works, why it’s widely used, and how it fits into the data management strategy of a fullstack Java application. What is Hibernate ORM? Hibernate ORM is an open-source Java framework that provides a powerful and flexible mechanism for mapping Java objects to database tables. It abstracts the low-level JDBC code, allowing developers to work with high-level object-oriented concepts. Instead of writing raw SQL queries, Hibernate allows developers to define database interactions using simple Java classes (also known as POJOs) and annotations or XML configurations...

Creating a Test Execution Report with Charts in Playwright

Modern test automation isn't just about running tests—it's also about presenting clear, visual feedback on test results. When working with Playwright, one of the most powerful end-to-end testing tools for modern web apps, generating detailed execution reports can help your team track progress, identify issues quickly, and make data-driven decisions. A visual report with charts brings your testing efforts to life. In this blog, we’ll walk through how to create a test execution report with charts using Playwright’s built-in capabilities along with third-party tools for enhanced visualization. Why Visual Reports Matter Plain text logs and console outputs are hard to parse at scale. A good report should answer questions like: How many tests passed or failed? What’s the overall success rate? Which tests are flaky or slow? How have test results changed over time? Visualizing this data with charts—like pie charts, bar graphs, or timelines—helps QA teams and stakeholders better underst...
