Interface HTTPListenerStats

All Superinterfaces:
Stats

public interface HTTPListenerStats
extends Stats

A Stats interface to represent the statistical data exposed by an HTTP Listener. This include data about the GlobalRequestProcessor and the ThreadPool. The GlobalRequestProcessor collects data about request processing from each of the RequestProcessor threads.

Since:
S1AS8.0
Version:
1.0

Method Detail

getBytesReceived

CountStatistic getBytesReceived()
Cumulative value of the bytesReceived by each of the RequestProcessors

Returns:
CountStatistic

getBytesSent

CountStatistic getBytesSent()
Cumulative value of the bytesSent by each of the RequestProcessors

Returns:
CountStatistic

getErrorCount

CountStatistic getErrorCount()
Cumulative value of the errorCount of each of the RequestProcessors. The errorCount represents the number of cases where the response code was >= 400

Returns:
CountStatistic

getCount200

CountStatistic getCount200()
Returns:
CountStatistic

getCount2xx

CountStatistic getCount2xx()

getCount302

CountStatistic getCount302()

getCount304

CountStatistic getCount304()

getCount3xx

CountStatistic getCount3xx()

getCount400

CountStatistic getCount400()

getCount401

CountStatistic getCount401()

getCount403

CountStatistic getCount403()

getCount404

CountStatistic getCount404()

getCount4xx

CountStatistic getCount4xx()

getCount503

CountStatistic getCount503()

getCount5xx

CountStatistic getCount5xx()

getCountOther

CountStatistic getCountOther()

getCountOpenConnections

CountStatistic getCountOpenConnections()

getMaxOpenConnections

CountStatistic getMaxOpenConnections()

getMaxTime

CountStatistic getMaxTime()
The longest response time for a request. This is not a cumulative value, but is the maximum of the response times for each of the RequestProcessors.

Returns:
CountStatistic

getProcessingTime

CountStatistic getProcessingTime()
Cumulative value of the processing times of each of the RequestProcessors. The processing time of a RequestProcessor is the average of request processing times over the request count.

Returns:
CountStatistic

getRequestCount

CountStatistic getRequestCount()
Cumulative number of the requests processed so far, by the RequestProcessors.

Returns:
CountStatistic

getCurrentThreadCount

CountStatistic getCurrentThreadCount()
The number of request processing threads currently in the thread pool

Returns:
CountStatistic

getCurrentThreadsBusy

CountStatistic getCurrentThreadsBusy()
The number of request processing threads currently in the thread pool, serving requests.

Returns:
CountStatistic

getMaxThreads

CountStatistic getMaxThreads()
The maximum number of request processing threads that are created by the listener. It determines the maximum number of simultaneous requests that can be handled

Returns:
CountStatistic

getMaxSpareThreads

CountStatistic getMaxSpareThreads()
The maximum number of unused request processing threads that will be allowed to exist until the thread pool starts stopping the unnecessary threads.

Returns:
CountStatistic

getMinSpareThreads

CountStatistic getMinSpareThreads()
The number of request processing threads that will be created when this listener is first started.

Returns:
CountStatistic
