Troubleshooting and FAQs

This section provides guidance on troubleshooting common issues with Tyk Streams, best practices for configuring and managing async APIs, and answers to frequently asked questions.

Common Issues and Resolutions

Issue 1: Failure to connect to the event broker

If Tyk Gateway is unable to establish a connection to the configured event broker (e.g., Kafka, MQTT), check the following:

• Verify that the broker connection details in the Tyk Dashboard are correct, including the hostname, port, and any required credentials.
• Ensure that the event broker is running and accessible from the Tyk Gateway instance.
• Check the network connectivity between the Tyk Gateway and the event broker. Use tools like telnet or nc to validate the connection.

Issue 2: Messages are not being published or consumed

If messages are not being successfully published to or consumed from the event broker, consider the following:

• Verify that the topic or queue names are correctly configured in the Tyk Dashboard and match the expected values in the event broker.
• Check the Tyk Gateway logs for any error messages related to message publishing or consumption. Adjust the log level to “debug” for more detailed information.
• Validate that the message format and schema match the expectations of the consumer or producer. Inspect the message payloads and ensure compatibility.

Issue 3: Async API performance is poor or connections are being throttled

If you observe performance issues or connection throttling with async APIs, consider the following:

• Review the configured rate limits and quotas for the async API. Adjust the limits if necessary to accommodate the expected traffic.
• Monitor the resource utilization of the Tyk Gateway instances and the event broker. Ensure that there is sufficient capacity to handle the load.
• Consider scaling the Tyk Gateway horizontally by adding more instances to distribute the traffic load.

Best Practices

• Use meaningful and descriptive names for your async APIs, topics, and subscriptions to improve readability and maintainability.
• Implement proper security measures, such as authentication and authorization, to protect your async APIs and restrict access to authorized clients only.
• Set appropriate rate limits and quotas to prevent abuse and ensure fair usage of the async API resources.
• Monitor the performance and health of your async APIs using Tyk’s built-in analytics and monitoring capabilities. Set up alerts and notifications for critical events.
• Version your async APIs to manage compatibility and enable seamless updates without disrupting existing clients.
• Provide comprehensive documentation for your async APIs, including details on message formats, schemas and example payloads, to assist developers in integrating with your APIs effectively.
