Class Counter2<F1,F2>

java.lang.Object

com.google.gerrit.metrics.Counter2<F1,F2>

Type Parameters:

F1 - type of the field.

F2 - type of the field.

All Implemented Interfaces:

RegistrationHandle

public abstract class Counter2<F1,F2>
extends Object
implements RegistrationHandle

Metric whose value increments during the life of the process.

Suitable uses are "total requests handled", "bytes sent", etc. Use Description.setRate() to suggest the monitoring system should also track the rate of increments if this is of interest.

For an instantaneous read of a value that can change over time (e.g. "memory in use") use a CallbackMetric.
