NLog AtomFile Target

NLog File Target writing to file using operating system API for atomic file appending (O_APPEND), so multiple processes can write concurrently to the same file.

If having trouble with output, then check NLog InternalLogger for clues. See also Troubleshooting NLog

See the NLog Wiki for available options and examples.

Linux Support

Uses libc open() with O_APPEND flag, which is supported on Linux and other Unix-like operating systems.

Register Extension

NLog will only recognize type-alias AtomFile when loading from NLog.config-file, if having added extension to NLog.config-file:

xml

<extensions>
    <add assembly="NLog.Targets.AtomicFile"/>
</extensions>

Alternative register from code using fluent configuration API:

csharp

LogManager.Setup().SetupExtensions(ext => {
   ext.RegisterTarget<NLog.Targets.AtomicFileTarget>();
});
