  - getLastErrorTimestamp
```
Date getLastErrorTimestamp()
```
    Returns the timestamp of the most recent error from the writer. This will be null if there have been no errors.
  - getLastErrorStacktrace
```
List<String> getLastErrorStacktrace()
```
    Returns the stack trace of the most recent error from the writer. This will be null if there have been no errors or if the error did not have an associated exception.
  - getOversizeMessages
```
int getOversizeMessages()
```
    Returns the number of messages that were either dropped or truncated because they were too large for the service to accept.
  - getMessagesSent
```
int getMessagesSent()
```
    Returns the number of messages successfully sent to the topic.
  - getLastBatchSize
```
int getLastBatchSize()
```
    Returns the number of messages in the most recent batch.
  - getMessagesSentLastBatch
```
int getMessagesSentLastBatch()
```
    Returns the number of messages successfully sent to the logstream in the last batch. This should be at least 1; higher values indicate how many messages will be lost if the program shuts down unexpectedly.
  - getMessagesRequeuedLastBatch
```
int getMessagesRequeuedLastBatch()
```
    Returns the number of messages requeued because they could not be sent. This should be 0; non-zero values indicate throttling or an error condition (see getLastErrorMessage() for more info).
