Insights on the Access Log Format in Ballerina

Question

I'm currently following the ballerina http access logs feature as documented in https://ballerina.io/learn/by-example/http-access-logs and I'm trying to identify the specific log format used in the ballerina http access logs. Specifically, I am checking whether we can get a request ID from these logs, where the ID is passed through a specific http header.

Answer 1

The access logs in the Ballerina http module have a fixed log format, and it is not possible to overwrite or customize this format directly. However, we can use interceptors to print logs with custom fields. Refer to the following,
