Constructor Detail

DefaultCommandLatencyCollectorOptions

protected DefaultCommandLatencyCollectorOptions(DefaultCommandLatencyCollectorOptions.Builder builder)

Method Detail

builder

public static DefaultCommandLatencyCollectorOptions.Builder builder()

Returns a new DefaultCommandLatencyCollectorOptions.Builder to construct DefaultCommandLatencyCollectorOptions.

Returns:

a new DefaultCommandLatencyCollectorOptions.Builder to construct DefaultCommandLatencyCollectorOptions.

create

public static DefaultCommandLatencyCollectorOptions create()

Create a new DefaultCommandLatencyCollectorOptions instance using default settings.

Returns:

a new instance of DefaultCommandLatencyCollectorOptions instance using default settings

disabled

public static DefaultCommandLatencyCollectorOptions disabled()

Create a DefaultCommandLatencyCollectorOptions instance with disabled event emission.

Returns:

a new instance of DefaultCommandLatencyCollectorOptions with disabled event emission

targetUnit

public TimeUnit targetUnit()

Description copied from interface: CommandLatencyCollectorOptions

Returns the target TimeUnit for the emitted latencies.

Specified by:

targetUnit in interface CommandLatencyCollectorOptions

Returns:

the target TimeUnit for the emitted latencies

targetPercentiles

public double[] targetPercentiles()

Description copied from interface: CommandLatencyCollectorOptions

Returns the percentiles which should be exposed in the metric.

Specified by:

targetPercentiles in interface CommandLatencyCollectorOptions

Returns:

the percentiles which should be exposed in the metric

resetLatenciesAfterEvent

public boolean resetLatenciesAfterEvent()

Description copied from interface: CommandLatencyCollectorOptions

Returns whether the latencies should be reset once an event is emitted.

Specified by:

resetLatenciesAfterEvent in interface CommandLatencyCollectorOptions

Returns:

true if the latencies should be reset once an event is emitted.

localDistinction

public boolean localDistinction()

Description copied from interface: CommandLatencyCollectorOptions

Returns whether to distinct latencies on local level. If true, multiple connections to the same host/connection point will be recorded separately which allows to inspect every connection individually. If false, multiple connections to the same host/connection point will be recorded together. This allows a consolidated view on one particular service.

Specified by:

localDistinction in interface CommandLatencyCollectorOptions

Returns:

true if latencies are recorded distinct on local level (per connection)

isEnabled

public boolean isEnabled()

Description copied from interface: CommandLatencyCollectorOptions

Returns whether the latency collector is enabled.

Specified by:

isEnabled in interface CommandLatencyCollectorOptions

Returns:

true if the latency collector is enabled
