Represents the actions a management agent can take when evaluating an event sink.
data ChannelSelector Source
type Fork = Process () -> IO ProcessId Source
Gross though it is, this synonym represents a function used to forking new processes, which has to be passed as a HOF when calling mxAgentController, since there's no other way to avoid a circular dependency with Node.hs
type MxSink s = Message -> MxAgent s (Maybe MxAction) Source
Type of a management agent's event sink.
This is the default management event, fired for various internal events around the NT connection and Process lifecycle. All published events that conform to this type, are eligible for tracing - i.e., they will be delivered to the trace controller.
Constructors
| MxSpawned ProcessId | fired whenever a local process is spawned |
| MxRegistered ProcessId String | fired whenever a process/name is registered (locally) |
| MxUnRegistered ProcessId String | fired whenever a process/name is unregistered (locally) |
| MxProcessDied ProcessId DiedReason | fired whenever a process dies |
| MxNodeDied NodeId DiedReason | fired whenever a node dies (i.e., the connection is broken/disconnected) |
| MxSent ProcessId ProcessId Message | fired whenever a message is sent from a local process |
| MxReceived ProcessId Message | fired whenever a message is received by a local process |
| MxConnected ConnectionId EndPointAddress | fired when a network-transport connection is first established |
| MxDisconnected ConnectionId EndPointAddress | fired when a network-transport connection is broken/disconnected |
| MxUser Message | a user defined trace event |
| MxLog String | a logging event - used for debugging purposes only |
| MxTraceTakeover ProcessId | notifies a trace listener that all subsequent traces will be sent to pid |
| MxTraceDisable | notifies a trace listener that it has been disabled/removed |
class Addressable a where Source
The class of things that we might be able to resolve to
a ProcessId (or not).
