https://wiki.10gen.com/display/10GEN/Logging+module
Outline:
Top of file (before platform/basic.h)
#define MONGO_LOG_DEFAULT COMPONENT ::mongo::logger::LogComponent::kSharding
Always include mongo/util/log.h where logging is done.
No more logging in headers
- mongo/util/log.h has been modified to prevent multiple inclusion (indirectly disallowing its use in headers)
severe(), error(), warning(), log() and LOG() will use log component defined in MONGO_LOG_COMPONENT_DEFAULT is available. Otherwise defaults to LogComponent::kDefault.
severe(), error(), warning(), log() will accept optional log component argument if MONGO_LOG_COMPONENT is not appropriate for the current scope.
For configuration, see mongo db manual for logComponentVerbosity server parameter or systemLog.component YAML configuration option.
