Class LogDaemon

Provides logging services by buffering messages and dispatching them into sinks. This is an asynchronous daemon with its own thread, meaning that Write(msg) never blocks for long.

Properties

FileExtension

Extension for log files

Declaration
[Config("$file-extension")]
[ExternalParameter(new string[]{"log"})]
public string FileExtension { get; set; }
Property Value
Type Description
System.String

Reliable

Determines whether this service blocks on stop longer until all buffered messages have been tried to be dispatched into all destinations. This property is true by default. Certain destinations may take considerable time to fail per message (i.e. database connection timeout), consequently buffered messages processing may delay service stop significantly if this property is true

Declaration
[Config("$reliable", true)]
[ExternalParameter(new string[]{"log"})]
public bool Reliable { get; set; }
Property Value
Type Description
System.Boolean

WriteInterval

Determines how often a log should be written to storage. The value of this property must be between 10 and 5000 (milliseconds)

Declaration
[Config("$write-interval-ms", 250)]
[ExternalParameter(new string[]{"log"})]
public int WriteInterval { get; set; }
Property Value
Type Description
System.Int32
