Traffic Server Software Developers Kit

Use the API void INKDebug (const char *tag, const char *format_str, ...) to add traces in your plugin. In this API:

Run Traffic Server with the -Ttag option. For example, if the tag is my-plugin, then the debug output goes to traffic.out.See below:

traffic_server -T”my-plugin”

Set the following variables in records.config (in the Traffic Server config directory):

proxy.config.diags.debug.enabled INT 1
proxy.config.diags.debug.tags STRING debug-tag-name

In this case, debug output goes to traffic.out.

Example:

INKDebug ("my-plugin", “Starting my-plugin at %d\n”, the_time);

The statement “Starting my-plugin at <time>” appears whenever you run Traffic Server with the my-plugin tag:

traffic_server -T”my-plugin”
