Method Detail

withCounters

IOStatisticsStoreBuilder withCounters(java.lang.String... keys)

Declare a varargs list of counters to add.

Parameters:

keys - names of statistics.

Returns:

this builder.

withGauges

IOStatisticsStoreBuilder withGauges(java.lang.String... keys)

Declare a varargs list of gauges to add.

Parameters:

keys - names of statistics.

Returns:

this builder.

withMaximums

IOStatisticsStoreBuilder withMaximums(java.lang.String... keys)

Declare a varargs list of maximums to add.

Parameters:

keys - names of statistics.

Returns:

this builder.

withMinimums

IOStatisticsStoreBuilder withMinimums(java.lang.String... keys)

Declare a varargs list of minimums to add.

Parameters:

keys - names of statistics.

Returns:

this builder.

withMeanStatistics

IOStatisticsStoreBuilder withMeanStatistics(java.lang.String... keys)

Declare a varargs list of means to add.

Parameters:

keys - names of statistics.

Returns:

this builder.

withDurationTracking

IOStatisticsStoreBuilder withDurationTracking(java.lang.String... prefixes)

Add a statistic in the counter, min, max and mean maps for each declared statistic prefix.

Parameters:

prefixes - prefixes for the stats.

Returns:

this

withSampleTracking

IOStatisticsStoreBuilder withSampleTracking(java.lang.String... prefixes)

A value which is tracked with counter/min/max/mean. Similar to withDurationTracking(String...) but without the failure option and with the same name across all categories.

Parameters:

prefixes - prefixes to add.

Returns:

the builder

build

IOStatisticsStore build()

Build the collector.

Returns:

a new collector.
