Usage and Errors

Errors and usage statistics that occur while an application is in use or are related to an application are record. The information does not contain user information and is very small as to use as little mobile data as possible. This data is sent to the Policy Server when performing a Policy Table update.

Application Errors

Errors and usage statistic that occur while an application is in use or are related to an application are recorded. The following properties are tracked in a property named after the application's ID.

Property Type Description
app_registration_language_gui String Language used to register the application using GUI.
app_registration_language_vui String Language used to register the application using VUI.
count_of_rejected_rpcs_calls Number Count of RPC calls that were rejected because access was not allowed due to a policy.
count_of_rejections_duplicate_name Number Number of times an application registration uses a name which is already registered in the current ignition cycle.
count_of_rejections_nickname_mismatch Number Number of times an app is not allowed to register because its registration does not match one of the app-specific policy nicknames.
count_of_removals_for_bad_behavior Number The module has criteria for identifying unacceptably bad application behavior. This tracks the number of times that distinction leads the module to unregister an application.
count_of_rfcom_limit_reached Number Number of times the maximum number of rfcom channels are used on a device by the application.
count_of_rpcs_sent_in_hmi_none Number Number of times an application tried to use an RPC (not unregisterAppInterface) in the HMI_NONE state. Counts the number of conflicts with the built-in/hardcoded restriction for HMI_STATE=NONE.
count_of_run_attempts_while_revoked Number Incremented when the user selects a revoked application from the HMI menu.
count_of_user_selections Number Number of times a user selected to run the app. Increment one when app starts via Mobile Apps Menu or VR. Increment one the first time the app leaves its default_hmi for HMI_FULL, as in the resuming app scenario. Do not increment anytime an app comes into HMI_FULL. Do not increment when cycling sources. For all 3 scenarios, both successful and unsuccessful app starts shall be counted.
minutes_in_hmi_background Number Number of minutes the application is in the HMI_BACKGROUND state.
minutes_in_hmi_full Number Number of minutes the application is in the HMI_FULL state.
minutes_in_hmi_limited Number Number of minutes the application is in the HMI_LIMITED state.
minutes_in_hmi_none Number Number of minutes the application is in the HMI_NONE state.

Property Type Description
