Add the function f
as a gauge with the given name.
Add the function f
as a gauge with the given name.
The returned gauge value is only weakly referenced by the StatsReceiver, and if garbage collected will eventually cease to be a part of this measurement: thus, it needs to be retained by the caller. Or put another way, the measurement is only guaranteed to exist as long as there exists a strong reference to the returned gauge and typically should be stored in a member variable.
Measurements under the same name are added together.
StatsReceiver.provideGauge when there is not a good location to store the returned gauge that can give the desired lifecycle.

This method is a convenience for Java programs, but is no longer needed because StatsReceivers.counter is usable from java.
Accurately indicates if this is a NullStatsReceiver.
Accurately indicates if this is a NullStatsReceiver. Because equality is not forwarded via scala.Proxy, this is helpful to check for a NullStatsReceiver.
Register a function f

This measurement exists in perpetuity.
Measurements under the same name are added together.
StatsReceiver.addGauge if you can properly control the lifecycle of the returned gauge.
Specifies the representative receiver.
Specifies the representative receiver. This is in order to expose an object we can use for comparison so that global stats are only reported once per receiver.
Prepend namespace
to the names of the returned StatsReceiver.
Prepend namespace
to the names of the returned StatsReceiver.
For example:
statsReceiver.scope("client").counter("adds") statsReceiver.scope("client").scope("backend").counter("adds")
will generate counters named /client/adds
and /client/backend/adds
.
Prepend a suffix value to the next scope.
Prepend a suffix value to the next scope.
For example:
statsReceiver.scopeSuffix("toto").scope("client").counter("adds")
will generate a counter named /client/toto/adds
.
