Measure Value collection method Gauge

Read during use, no additional function support required

Counter

Increase (long value = 1, string item = null): void // Increase the count

Decrease (long value = 1, string item = null): void // reduce the count

Histogram

Update (double value, string userValue = null): void

Meter

Mark (long count = 1, string item = null): void

Timer

Record (long duration, TimeUnit unit, string userValue = null): void

Timer (Action action, string userValue = null): void

Timer <T> (Func <T> action, string userValue = null): T
