Package org.eclipse.microprofile.metrics
Interface Gauge<T>
- Type Parameters:
T
- the type of the metric's value
- All Superinterfaces:
Metric
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
A gauge metric is an instantaneous reading of a particular value. To instrument a queue's depth,
for example:
final Queue<String> queue = new ConcurrentLinkedQueue<String>();
final Gauge<Integer> queueDepth = new Gauge<Integer>() {
public Integer getValue() {
return queue.size();
}
};
