All events stored by the system have common parameters which are called contextual parameters
.
These parameters will be systematically stored by the engine, whatever it is configuration, application or system.
They will therefore always be available and it will not be necessary to register specifically, the system will do so automatically.

In dashboards, context parameters can be used to filter data in search options or as data used to represent to the user.
Contextual parameters are all stored under the key event.context
.
If you need to retrieve one of the variables, you can access it by its key event.context.VARIABLE_NAME
.
For instance, surfer’s role UID will be retrieved with event.context.surfer.role.uid
.
connexion_search_option.getQuery().mustNotEquals("event.context.surfer.role.uid", "role_1");
connexion_search_option.putAggregation("pie_connexions_by_role", Analytics.TermsAggregation("event.context.surfer.role.uid", 20));

Since 11.15.0 it is now possible to add custom surfer’s parameters to the context parameters. Simply add the structure field tag analytics/surfer
on any user property to have it logged at each analytics event.
When available those parameters will be found under the extra
property of the context parameters (ie. event.context.extra.bolanguid).
A custom context parameter will always be retrieved with event.context.extra.VARIABLE_NAME
.
