Instrument identifier.
Instrument identifier.
MUST be >=1 and <32.
Values between 1 and 7 are reserved for Akka internal use.
Called when the message has been deserialized.
Called when the message has been deserialized.
The size
is the total serialized size in bytes of the complete message including akka specific headers and any
RemoteInstrument
metadata.
If serializationTimingEnabled
returns true, then time
will be the total time it took to deserialize all data
in the message in nanoseconds, otherwise it is 0.
Called right before putting the message onto the wire.
Called right before putting the message onto the wire.
Parameters MAY be null
(except message
and buffer
)!

If serializationTimingEnabled
returns true, then time
will be the total time it took to serialize all data
in the message in nanoseconds, otherwise it is 0.
Called while deserializing the message once a message (containing a metadata field designated for this instrument) is found.
Called while serializing the message.
Called while serializing the message.
Parameters MAY be null

Should the serialization be timed? Otherwise times are always 0.
INTERNAL API
Part of the monitoring SPI which allows attaching metadata to outbound remote messages, and reading in metadata from incoming messages.
Multiple instruments are automatically handled, however they MUST NOT overlap in their idenfitiers.
Instances of
RemoteInstrument
are created from configuration. A new instance of RemoteInstrument will be created for each encoder and decoder. It's only called from the stage, so if it doesn't delegate to any shared instance it doesn't have to be thread-safe.
