Access logs

Ballerina supports HTTP access logs for HTTP services. The access log format used is the combined log format. To enable access logs, set console=true under the ballerina.http.accessLogConfig in the Config.toml file. Also, the path field can be used to specify the file path to save the access logs.

For more information on the underlying module, see the HTTP module.
