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; 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:
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.
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.
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.
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 is a part of Applications Manager's AWS monitoring solution that also includes AWS ECS monitoring. Our AWS Lambda monitoring dashboard displays information about your Lambda configurations in a single tab for easy reference. Data like resource stats, security and network information, function details and other configuration details are available at your disposal.
It allows us to track crucial metrics such as response times, resource utilization, error rates, and transaction performance. The real-time monitoring alerts promptly notify us of any issues or anomalies, enabling us to take immediate action.
