Using IOPipe to instrument your lambda functions

IOPipe is a multi-tenant SaaS application that hooks into your Lambda functions via a function wrapper that you apply to your event handlers. It records detailed trace data from your function invocations so that you can profile your code as it runs. It helps developers while they are debugging their code, and it also helps operations spot problems quickly. Each time you make an AWS API call from within your code, the performance of that call is recorded so that you can see exactly where excess time is being spent. For example, you can see the average time it takes to execute a query of your DynamoDB table, or how long it takes to put an object into an S3 bucket.
