Method Detail

getLastResponseCode

public java.lang.Integer getLastResponseCode()

Description copied from interface: ResponseStatistics

Returns the response code of a last response written by the application.

Specified by:

getLastResponseCode in interface ResponseStatistics

Returns:

Last response status code.

getResponseCodes

public java.util.Map<java.lang.Integer,java.lang.Long> getResponseCodes()

Description copied from interface: ResponseStatistics

Returns statistics of response codes produces by the application. Keys of a returned map are response status codes and values is the the count of responses with these status count. Values are measured since start of the application.

Specified by:

getResponseCodes in interface ResponseStatistics

Returns:

Map with status codes keys and count as values.

snapshot

public ResponseStatistics snapshot()

Description copied from interface: ResponseStatistics

Get the immutable and consistent snapshot of the monitoring statistics. Working with snapshots might have negative performance impact as snapshot must be created but ensures consistency of data over time. However, the usage of snapshot is encouraged to avoid working with inconsistent data. Not all statistics must be updated in the same time on mutable version of statistics.

Specified by:

snapshot in interface ResponseStatistics

Returns:

Snapshot of response statistics.
