Method Detail

reset

@ManagedOperation
void reset()

getSendCount

@ManagedMetric(metricType=COUNTER,
               displayName="MessageChannel Send Count")
int getSendCount()

Returns:

the number of successful sends

getSendErrorCount

@ManagedMetric(metricType=COUNTER,
               displayName="MessageChannel Send Error Count")
int getSendErrorCount()

Returns:

the number of failed sends (either throwing an exception or rejected by the channel)

getTimeSinceLastSend

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Time Since Last Send in Seconds")
double getTimeSinceLastSend()

Returns:

the time in seconds since the last send

getMeanSendRate

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Send Rate per Second")
double getMeanSendRate()

Returns:

the mean send rate (per second)

getMeanErrorRate

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Error Rate per Second")
double getMeanErrorRate()

Returns:

the mean error rate (per second). Errors comprise all failed sends.

getMeanErrorRatio

@ManagedMetric(metricType=GAUGE,
               displayName="Mean Channel Error Ratio per Minute")
double getMeanErrorRatio()

Returns:

the mean ratio of failed to successful sends in approximately the last minute

getMeanSendDuration

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Send Mean Duration in Milliseconds")
double getMeanSendDuration()

Returns:

the mean send duration (milliseconds)

getMinSendDuration

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Send Min Duration in Milliseconds")
double getMinSendDuration()

Returns:

the minimum send duration (milliseconds) since startup

getMaxSendDuration

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Send Max Duration in Milliseconds")
double getMaxSendDuration()

Returns:

the maximum send duration (milliseconds) since startup

getStandardDeviationSendDuration

@ManagedMetric(metricType=GAUGE,
               displayName="Channel Send Standard Deviation Duration in Milliseconds")
double getStandardDeviationSendDuration()

Returns:

the standard deviation send duration (milliseconds)

getSendDuration

Statistics getSendDuration()

Returns:

summary statistics about the send duration (milliseconds)

getSendRate

Statistics getSendRate()

Returns:

summary statistics about the send rates (per second)

getErrorRate

Statistics getErrorRate()

Returns:

summary statistics about the error rates (per second)
