Description

There is partial support for tracking ioBuffer usage with TRACK_BUFFER_USER and the configuration option proxy.config.res_track_memory. The underlying data structure to store the information is missing.

This information will be reported when the user sends a SIGUSR1 signal to traffic_server or is part of the periodic memory logging reports.

Example:

                                          Location |          Size In-use
