Tracing Service
This section describes the Tracing Service Support available in Magentix2. This Tracing Service Support allows agents in a Multiagent System (MAS) share information in an indirect way
by means of trace events.
Before describing the API provided by Magentix2 to share tracing information, the following
sections will present TRAMMAS, the trace model which was followed to incorporate event
tracing facilities to Magentix2.
3.8.1
Trace Model and Features
The trace event model incorporated to Magentix is described in detail in [Búrdalo et al., 2010].
This section will comment briefly the main characteristics of the model and those of its features
which have been incorporated to the platform.
The trace model described in [Búrdalo et al., 2010] offers any entity in the system (active or
passive) the possibility to share information, in the form of trace events, with other entities in
the system. From the point of view of the trace model, entities in the system are seen as tracing
entities; this is, entities which are able to generate and/or receive trace events. Trace events are
offered by tracing entities as different tracing services, which can be requested by interested
tracing entities when they want to receive these trace events.
3.8.1.1
Supported Features
The present version of Magentix2 does not support all of the tracing features considered in
the model. Those which are not yet supported will be incorporated in future versions of the
