Filtering allows a particular ILog
instance to only record a subset of incoming log events. Events can be filtered by level, properties or literally any other information present.
Filter by level
Set a minimum allowed log level (events of lower levels will be dropped):
Selectively disable some log levels:
Filter by a single property
Select events having a property with given name and a of given type value satisfying a predicate:
Drop events having a property with given name and a value of given type satisfying a predicate:
Filter by all properties
Select events whose properties dictionary satisfies given predicate:
Drop events whose properties dictionary satisfies given predicate:
Filter by source context
Select events having a source context with given value (values are case-insensitive prefixes):
Drop events having a source context with given value (values are case-insensitive prefixes):
Drop events below some level having a source context with given value (values are case-insensitive prefixes):
There's also an alternative syntax that allows to infer context values from type names:
Filter by arbitrary event content
Select events satisfying given predicate:
Drop events satisfying given predicate:
