Namespace Akka.Event

Classes

ActorEventBus<TEvent, TClassifier>

This class represents an EventBus<TEvent, TClassifier, TSubscriber> where the subscriber type is an IActorRef.

AllDeadLetters

Represents a message that could not be delivered to it's recipient. This message wraps the original message, the sender and the intended recipient of the message.

Subscribe to this class to be notified about all DeadLetter (also the suppressed ones) and Dropped.

BusLogging

A logging adapter implementation publishing log events to the event stream.

DeadLetter

When a message is sent to an Actor that is terminated before receiving the message, it will be sent as a DeadLetter to the ActorSystem's EventStream

DeadLetterListener

This class represents an actor responsible for listening to DeadLetter messages and logging them using the EventStream.

Debug

This class represents a Debug log event.

DefaultLogger

Default logger implementation that outputs logs to the Console.

DefaultLogMessageFormatter

This class represents an ILoggingAdapter implementation that uses Format(String, Object[]) to format log messages.

Dropped

Envelope that is published on the eventStream wrapped in DeadLetter for every message that is dropped due to overfull queues or routers with no routees.

When this message was sent without a sender IActorRef, sender will be NoSender , i.e. null.

DummyClassForStringSources

This class represents a marker which is inserted as originator class into LogEvent when the string representation was supplied directly.

Error

This class represents a Error log event.

EventBus<TEvent, TClassifier, TSubscriber>

This class provides base publish/subscribe functionality for working with events inside the system.

EventStream

The EventStream is a pub-sub stream of events that can be both system and user generated.

The subscribers are IActorRef instances and events can be any object. Subscriptions are hierarchical meaning that if you listen to an event for a particular type you will receive events for that type and any sub types.

If the debug flag is activated any operations on the event stream will be published as debug level events.

EventStreamExtensions

Extension methods for the EventStream class.

ExactMatchLogSourceFilter

Info

This class represents an Info log event.

InitializeLogger

This class represents a message used to initialize a logger.

LogEvent

This class represents a logging event in the system.

LogFilterBase

Base class for all log filters

LogFilterBuilder

Can be used to build a set of log filters to be used in conjunction with the LogFilterSetup.

LogFilterEvaluator

Runs inside the logging actor and evaluates if a log message should be kept.

LogFilterSetup

Used to specify filters that can be used to curtail noise from sources in the Akka.NET log stream.

LoggerInitialized

This class represents a message used to notify subscribers that a logger has been initialized.

LoggerMailbox

Mailbox type used by loggers

Logging

This class provides the functionality for creating logger instances and helpers for converting to/from LogLevel values.

LoggingAdapterBase

This class represents the base logging adapter implementation used to log events within the system.

LoggingBus

This class represents an event bus which subscribes loggers to system LogEvents.

LoggingExtensions

LogMessage

Represents a log message which is composed of a format string and format args.

LogMessageExtensions

Extension methods for creating LogMessage instances.

MinimalLogger

NoLogger

This class represents an ILoggingAdapter implementation used when messages are to be dropped instead of logged.

RegexLogMessageFilter

RegexLogSourceFilter

Uses a regular expression to filter log messages based on their source.

StandardOutLogger

This class represents an event logger that logs its messages to standard output (e.g. the console).

This logger is always attached first in order to be able to log failures during application start-up, even before normal logging is started.

Subscription<TSubscriber, TClassifier>

Represents a Subscription to the EventBus.

SuppressedDeadLetter

Similar to DeadLetter with the slight twist of NOT being logged by the default dead letters listener. Messages which end up being suppressed dead letters are internal messages for which ending up as dead-letter is both expected and harmless.

TraceLogger

This class represents an event logger that logs its messages using a configured trace listener.

To use activate this logger, modify the loggers section in your Akka.NET configuration like so,

akka {
  ...
  loggers = [""Akka.Event.TraceLogger, Akka""]
  ...
}

Further configuration may be required in your main configuration (e.g. app.config or web.config) to properly set up the trace. See here for more information regarding .NET tracing.

UnhandledMessage

This message is published to the EventStream whenever an Actor receives a message it doesn't understand

Warning

This class represents a Warning log event.

Structs

LogSource

This object holds predefined formatting rules for log sources.

In case an ActorSystem is provided, the following apply:

ActorBase and IActorRef will be represented by their absolute path.
providing a String as source will append "(ActorSystem address)" and use the result.
providing a Type will extract its simple name, append "(ActorSystem address)", and use the result.
