Class LongCounter

java.lang.Object
com.gigaspaces.metrics.Metric
com.gigaspaces.metrics.LongCounter
@Deprecated public class LongCounter extends Metric
Deprecated.
Use AtomicLong with Micrometer Gauge, or Counter for monotonic counters
An incrementing and decrementing counter metric for long values.

DEPRECATED: Use AtomicLong directly and register as Micrometer Gauge.

Migration Guide: 


 // OLD:
 LongCounter counter = new LongCounter();
 counter.inc();
 long value = counter.getCount();

 // NEW (for counters that can go up/down):
 AtomicLong counter = new AtomicLong(0);
 counter.incrementAndGet();
 long value = counter.get();
 // Register as Micrometer Gauge:
 Gauge.builder("metric_name", counter, AtomicLong::get)
     .tags(tags)
     .register(meterRegistry);

 // NEW (for monotonic counters):
 Counter counter = Counter.builder("metric_name")
     .tags(tags)
     .register(meterRegistry);
 counter.increment();
 double value = counter.count();
