:relfileprefix: ../../../
:mrdocs:

Create a file observer with the specified `stdoutThreshold`.

== Synopsis

Declared in `<ball_fileobserver.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
explicit
FileObserver(
    xref:BloombergLP/ball/Severity/Level.adoc[Severity::Level] stdoutThreshold,
    xref:BloombergLP/bslma/Allocator.adoc[bslma::Allocator]* basicAllocator = 0);
----

== Description

Create a file observer that publishes log records to `stdout` if their severity is at least as severe as the specified `stdoutThreshold` level, and has file logging initially disabled. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. Note that `isPublishInLocalTimeEnabled` returns `false` following construction indicating that the timestamp attribute of published records will be written in UTC time (see `enablePublishInLocalTime`). Also note that independent default record formats are in effect for `stdout` and file logging (see `setLogFormat`).

== Parameters
