Monitoring AWS Lambda with Prometheus and Sysdig

The blog post explores how to effectively monitor AWS Lambda using Sysdig Monitor and Prometheus by leveraging the CloudWatch exporter, enabling a comprehensive view of serverless services. As serverless computing gains traction, AWS Lambda, a Function as a Service (FaaS) resource, necessitates robust monitoring to ensure optimal performance. Prometheus, an open-source monitoring solution, can gather metrics across various cloud services using exporters like the yet-another-cloudwatch-exporter (YACE), which the post details setting up within a Kubernetes environment to collect Lambda metrics from AWS CloudWatch. Key metrics such as errors, concurrency, throttling, latency, and traffic are discussed, along with PromQL queries for alerting on potential issues like configuration errors and performance inefficiencies. The integration process into Sysdig Monitor is described, highlighting the use of dashboards for visualizing Lambda's performance and the importance of optimizing CloudWatch's granularity to manage costs effectively. The post concludes by inviting readers to try this integration and provides resources for further exploration, including dashboards and alerts available on PromCat.io.
