Log Targets

The Log Target feature in Contentstack Launch enables you to forward server and edge logs generated by Launch-hosted SSR websites, Cloud Functions, or Edge Functions to third-party monitoring services.

You can set up an OpenTelemetry Collector service to receive logs through a TLS-secured OTLP (OpenTelemetry Protocol) over gRPC endpoint and forward them to your preferred log provider.

OpenTelemetry is an industry-standard framework that simplifies integration with major log provider platforms, ensuring seamless implementation.

Tip: You do not need to host your own OpenTelemetry Collector service if your log aggregator platform already supports ingesting logs in OpenTelemetry format over a gRPC endpoint.

With this feature, the generated server and edge logs can be seamlessly integrated with external monitoring tools, providing insights, alerts, and persistent data storage for better management and analysis of log data.

This step-by-step guide lets you create Log Targets in Contentstack Launch to forward your project logs to specific endpoints.

1. Contentstack account
2. Access to Launch for your organization
3. OTEL Collector service capable of receiving logs configured with TLS-secured gRPC Endpoint

Follow the steps below to create a Log Target:

1. Log in to Contentstack and click the Launch app.
2. Click the Settings icon to enter the Log Targets page. 
3. Click the + Create New Log Target button to create a new Log Target. 
4. In the modal that appears, enter the following:
   1. Log Target Name: A name for the Log Target.
   2. Endpoint URL: An Open Telemetry OTLP/gRPC endpoint where logs will be transmitted.
   3. Authorization Type: Type of authorization.
   4. Token: A secret token attaches to Log Target requests as an Auth Bearer Token header. This helps validate that the request comes from the correct source, i.e., a Log Target.
   
5. Click the Create Log Target button.

You see that the Log Target is created successfully to forward your project logs to the mentioned Endpoint URL.

Follow the steps below to edit a Log Target:

1. Click the Settings icon to enter the Log Targets page.
2. Against the Log Target that you want to edit, click the ellipses under Actions, and then click Edit. 
3. Edit the Log Target details as required and then click the Update button to save the updated details. 

Follow the steps below to delete a Log Target:

1. Click the Settings icon to enter the Log Targets page.
2. Against the Log Target that you want to delete, click the ellipses under Actions, and then click Delete. 
3. In the modal that appears, click the Yes, Delete button to delete the Log Target. 

Additional Resource: Use this GitHub repository as an example to set up a TLS-secured OTLP/gRPC endpoint that receives and exports logs to CloudWatch.

• Launch can forward only up to 1000 logs in a single request.
