## net.i2p.router
Class MessageHistory

    java.lang.Object
      net.i2p.router.MessageHistory

    public class MessageHistory

extends Object

Simply act as a pen register of messages sent in and out of the router. This will be pulled out later on, but is useful now for debugging. (with clock synchronization, this will generate a log that can be used to analyze the entire network, if everyone provides their logs honestly)

Field Summary
`static String` | `DEFAULT_MESSAGE_HISTORY_FILENAME`
`static String` | `PROP_KEEP_MESSAGE_HISTORY` config property determining whether we want to debug with the message history - default false
`static String` | `PROP_MESSAGE_HISTORY_FILENAME` config property determining where we want to log the message history, if we're keeping one
