Detailed Description

Enumeration Type Documentation

NDDS_Config_LogVerbosity

enum NDDS_Config_LogVerbosity

The verbosities at which RTI Connext diagnostic information is logged.

Enumerator
NDDS_CONFIG_LOG_VERBOSITY_SILENT	No further output will be logged.
NDDS_CONFIG_LOG_VERBOSITY_ERROR	Only error and fatal error messages will be logged. An error indicates something wrong in the functioning of RTI Connext. The most common cause of errors is incorrect configuration.
NDDS_CONFIG_LOG_VERBOSITY_WARNING	Both error and warning messages will be logged. A warning indicates that RTI Connext is taking an action that may or may not be what you intended. Some configuration information is also logged at this verbosity to aid in debugging.
NDDS_CONFIG_LOG_VERBOSITY_STATUS_LOCAL	Errors, warnings, and verbose information about the lifecycles of local RTI Connext objects will be logged.
NDDS_CONFIG_LOG_VERBOSITY_STATUS_REMOTE	Errors, warnings, and verbose information about the lifecycles of remote RTI Connext objects will be logged.
NDDS_CONFIG_LOG_VERBOSITY_STATUS_ALL	Errors, warnings, verbose information about the lifecycles of local and remote RTI Connext objects, and periodic information about RTI Connext threads will be logged.

NDDS_Config_LogLevel

enum NDDS_Config_LogLevel

Level category assigned to RTI Connext log messages returned to an output device.

Enumerator
NDDS_CONFIG_LOG_LEVEL_FATAL_ERROR	The message describes a fatal error. A fatal error indicates an unrecoverable situation in the functioning of RTI Connext. Error messages with this log level usually indicate a violation of an internal invariant or a segfault, and may include the function call stack where the fatal error happened.
NDDS_CONFIG_LOG_LEVEL_ERROR	The message describes an error. An error indicates a non-fatal problem in the functioning of RTI Connext. Errors are usually recoverable and will not stop application execution, although they may prevent some features from working properly. The most common cause of non-fatal errors is incorrect configuration and incorrect arguments.
NDDS_CONFIG_LOG_LEVEL_WARNING	The message describes a warning. A warning indicates that RTI Connext is taking an action that may or may not be what you intended. Some configuration information is also logged at this verbosity to aid in debugging.
NDDS_CONFIG_LOG_LEVEL_STATUS_LOCAL	The message contains information about the lifecycles of local RTI Connext objects will be logged.
NDDS_CONFIG_LOG_LEVEL_STATUS_REMOTE	The message contains information about the lifecycles of remote RTI Connext objects will be logged.
NDDS_CONFIG_LOG_LEVEL_DEBUG	The message contains debug information that might be relevant to your application.

NDDS_Config_LogCategory

enum NDDS_Config_LogCategory

Categories of logged messages.

The NDDSConfigLogger::get_verbosity_by_category and NDDSConfigLogger::set_verbosity_by_category can be used to specify different verbosities for different categories of messages.

Enumerator
NDDS_CONFIG_LOG_CATEGORY_PLATFORM	Log messages pertaining to the underlying platform (hardware and OS) on which RTI Connext is running are in this category.
NDDS_CONFIG_LOG_CATEGORY_COMMUNICATION	Log messages pertaining to data serialization and deserialization and network traffic are in this category.
NDDS_CONFIG_LOG_CATEGORY_DATABASE	Log messages pertaining to the internal database in which RTI Connext objects are stored are in this category.
NDDS_CONFIG_LOG_CATEGORY_ENTITIES	Log messages pertaining to local and remote entities and to the discovery process are in this category.
NDDS_CONFIG_LOG_CATEGORY_API	Log messages pertaining to the API layer of RTI Connext (such as method argument validation) are in this category.
NDDS_CONFIG_LOG_CATEGORY_ALL	Log messages pertaining to all category of RTI Connext.

NDDS_Config_LogPrintFormat

enum NDDS_Config_LogPrintFormat

The format used to output RTI Connext diagnostic information.

Enumerator
NDDS_CONFIG_LOG_PRINT_FORMAT_DEFAULT	(default) Print message, method name, and Activity Context (what was happening when the event occurred).
NDDS_CONFIG_LOG_PRINT_FORMAT_TIMESTAMPED	Print message, method name, Activity Context, and timestamp.
NDDS_CONFIG_LOG_PRINT_FORMAT_VERBOSE	Print message with all available context information (includes thread identifier, Activity Context).
NDDS_CONFIG_LOG_PRINT_FORMAT_VERBOSE_TIMESTAMPED	Print message with all available context information, and timestamp.
NDDS_CONFIG_LOG_PRINT_FORMAT_DEBUG	Print a set of fields (including the Activity Context and backtrace information) that may be useful for internal debugging.
NDDS_CONFIG_LOG_PRINT_FORMAT_MINIMAL	Print only message number and method name.
NDDS_CONFIG_LOG_PRINT_FORMAT_MAXIMAL	Print all available fields (including backtrace information).
