Epsagon uses tracing to extract events from production code. After integrating Epsagon into your application, either automatically or manually, it will instrument the code every time it's loaded. While the code is running, events will be sent to Epsagon and analyzed in real-time to generate tracing maps, alerts, and insights.
Epsagon was built for modern cloud applications, meaning you can use any kind of workload. It operates only at the code-level, using a lightweight agent SDK. This allows it to run on containerized, serverless, or any other application.
No. Epsagon supports integrations with a variety of common frameworks in multiple languages and will do all the instrumentation automatically for you. For example, auto-tracing will automatically pick up your AWS Lambda functions. No code changes required.
Inviting team members is free at Epsagon. Head to your settings page and just invite them by typing their emails, separated by a comma.

If you still don't see any traces, contact us at the How to Get Help.
You can add
DISABLE_EPSAGON=TRUE as an environment variable to completely disable in local, tests, or dev environment.
Epsagon does not recommend sampling traces, especially in distributed environments. If you still wish to consult with us, contact us at the How to Get Help.
If you choose, you can use our layer in your Python or Node.js function instead of installing it.
- Python layer ARN:
- Node.js layer ARN:
To get the latest layer details you can get to this endpoint:
When using the Epsagon auto-tracing on Node or Python functions, it adds a layer and updates the handler to point to a file in it. Since it can't be opened, the following notice appears:
This is NOT an issue, the function is completely fine - Your function is still running regularly, and you can edit the files.
In Node you'll see the message -
Lambda can't find the file /opt/nodejs/node_modules/epsagon.js. Make sure that your handler upholds the format: file-name.method.
In Python you'll see the message -
Lambda can't find the file epsagon.wrapper. Make sure that your handler upholds the format: file-name.method.
Yes. You can follow this tutorial.
Invocations, log view, and alerts are currently not available for this function / Function subscribed to a different consumer
In order to parse invocations, Epsagon subscribes to your CloudWatch log group and parse it. Since there is only one destination that can be applied, if you found the following warning next to your function:
It means that your function is already subscribed. To fix that, we can subscribe the logs to Epsagon, or provide you with a solution to stream logs to multiple destinations. Contact us at the How to Get Help.
Getting ROLLBACK_COMPLATE when deploying the CloudFormation stack / Can't deploy the CloudFormation stack
If you are facing any errors deploying the Epsagon CloudFormation stack, first make sure that it is not already deployed in your account. To do that you can look for a stack named Epsagon in your CloudFormation dashboard, or an IAM role named EpsagonRole.
In such cases or any other issue contact us at the How to Get Help.
