# Comprehensive AWS Lambda monitoring for optimal serverless performance AWS Lambda is an event-based serverless computing platform, with built-in auto scaling and infrastructure management capabilities. Despite many advantages that Amazon Lambda offers, a monitoring system is required to manage its complex environments, scalable workloads and resources, and to help reduce the MTTR and possibly prevent avoidable issues. Applications Manager gives you rich, actionable insights into your Lambda environment. Our **AWS Lambda monitoring tool** helps you proactively monitor the KPIs that are vital to your applications by fetching the stats real time and aggregating them for [historical analysis](https://www.manageengine.com/products/applications_manager/performance-report.html); and also employs machine learning techniques to forecast growth and usage. Applications Manager's **AWS Lambda monitoring** is an intelligent tool with the following advantages and capabilities: - Monitor AWS Lambda functions and the associated performance data - Functions as a solid fault management system with intuitive analytical reports - Identify and resolve issues with in-depth root cause analysis - Pick out performance abnormalities with Lambda applications using alarms & thresholds - Ability to reduce manual intervention by enabling corrective actions to be performed automatically ## Key metrics to monitor with Lambda monitoring ### Invocations Applications Manager collects invocation stats from Amazon CloudWatch and provides you with processed information like invocations/min, success and error rates. Monitor AWS Lambda to keep track of failed, throttled, and successful invocations. Monitoring invocations will help you keep track of application activity and how your functions are performing. A drop in invocations could indicate a problem with the function or a connected AWS service. ![ManageEngine Applications Manager dashboard showing real-time AWS Lambda function performance metrics and health status.](https://www.manageengine.com/products/applications_manager/images/amazon-lambda-monitoring-1.webp) ### Concurrent events & executions Monitoring AWS Lambda is important because, if the concurrent execution limit or the reserved concurrency limit configured on the function is exceeded, AWS Lambda throttles additional invocation requests. Keeping track of concurrency helps you manage over-provisioned functions and scale your functions to support the flow of application traffic. You can also monitor AWS Lambda functions for more details about concurrent executions like provisioned concurrency stats, concurrent executions and invocations. ![AWS Lambda Monitoring in AWS - Manageengine Applications Manager](https://www.manageengine.com/products/applications_manager/images/amazon-lambda-monitoring-2.webp) ### Errors & failures In asynchronous invocations, it is usual to encounter destination delivery failures and dead letter queues. Both these errors occur due to incorrect permissions, inappropriate configuration of resources, or size limits, for the most part. **AWS Lambda function monitoring** can be useful in keeping track of invocations and their configurations to pre-emptively avoid these errors beforehand. Applications Manager also provides information on the time taken by each event and iteration age for stream-based invocations. Get notified when the value of the iterator age metric increases and take steps to decrease the time taken by the function to process records in a batch of data. ![AWS Lambda performance Monitoring - Manageengine Applications Manager](https://www.manageengine.com/products/applications_manager/images/amazon-lambda-monitoring-3.webp) By monitoring crucial AWS Lambda performance metrics such as the duration, you can perceive the speed at which the events are executed with dimensions like average, minimum and maximum time taken to execute the function. Monitoring duration will also help you manage AWS costs better, especially if you're managing large volumes of requests across hundreds of functions. ![AWS Lambda Monitoring Tool - Manageengine Applications Manager](https://www.manageengine.com/products/applications_manager/images/amazon-lambda-monitoring-4.webp) ## Achieving unmatched reliability and cost efficiency in your serverless stack Effective AWS Lambda monitoring with ManageEngine Applications Manager is not just about identifying problems; it's about enabling a proactive approach to operational excellence, leading to unmatched reliability and significant cost efficiencies. By providing granular visibility into performance trends, resource utilization, and error rates, our solution empowers teams to prevent outages before they impact users and drastically reduce Mean Time To Resolution (MTTR). The detailed insights into invocation patterns and duration allow for precise capacity planning, ensuring your Lambda functions are always optimally provisioned, thereby avoiding both over-provisioning (which wastes resources and increases costs) and under-provisioning (which leads to throttling and performance degradation). ManageEngine Applications Manager's comprehensive reporting capabilities further assist in analyzing long-term trends and making data-driven decisions for cost optimization initiatives. By providing a trusted, expert-level view into your serverless infrastructure, Applications Manager helps you harness the full potential of AWS Lambda, driving both operational stability and financial prudence. ## Set up your own Lambda function monitor now!

Lambda monitoring is used to collect performance metrics such as health, availability, invocation status, invocation rate, concurrent execution status, processing duration, iterator age, and delivery failure count of your AWS service. A tool is generally employed to perform AWS Lambda monitoring where it automatically raises an alarm whenever any of the critical performance parameter exceeds the allowable threshold. Monitoring your AWS Lambda function allows administrators to troubleshoot errors and failtures before they affect end-users and ensure higher availability of applications running on the service. ### How to monitor AWS Lambda function? Though AWS offers its own monitoring service, Lambda monitoring tools like Applications Manager can come in handy as they offer tons of functionalities like highly visual performance graphs, customizable dashboards, machine learning, growth trend predictions, capacity planner, and more. It also comes with round-the-clock technical support where assistance is provided through the entire installation process.
