Method Detail

createCounter

Counter createCounter(java.lang.String name,
                      java.util.Map<java.lang.String,java.lang.String> tags)

Creates a counter with the given gauge name and set of tags. The actual metric name is a combination of those two values. The counter starts at 0.

Parameters:

name - the counter name

tags - the tags to add to the counter

Returns:

a Counter with a metric name following the counter name and tags

Metrics.addTagsToMetricName(String, Map)

createTimer

Timer createTimer(java.lang.String name,
                  java.util.Map<java.lang.String,java.lang.String> tags)

Creates a timer with the given timer name and set of tags. The actual metric name is a combination of those two values. The timer starts at 0.

Parameters:

name - the timer name

tags - the tags to add to the timer

Returns:

a Timer with a metric name following the counter name and tags

createGauge

Gauge createGauge(java.lang.String name,
                  java.util.Map<java.lang.String,java.lang.String> tags)

Creates a gauge with the given gauge name and set of tags. The actual metric name is a combination of those two values. The timer starts at 0.

Parameters:

name - the gauge name

tags - the tags to add to the gauge

Returns:

a Gauge with a metric name following the gauge name and tags
