InMemoryStatsReceiver

class InMemoryStatsReceiver extends StatsReceiver

An in-memory implementation of StatsReceiver, which is mostly used for testing.

Note that an InMemoryStatsReceiver does not conflate Seq("a", "b") and Seq("a/b") names no matter how they look when printed.

val isr = new InMemoryStatsReceiver
isr.counter("a", "b", "foo")
irs.counter("a/b", "bar")

irs.print(Console.out) // will print two lines "a/b/foo 0" and "a/b/bar 0"

assert(isr.counters(Seq("a", "b", "foo") == 0)) // ok
assert(isr.counters(Seq("a", "b", "bar") == 0)) // fail

    Register a function f as a gauge with the given name that has a lifecycle with no end.

    This measurement exists in perpetuity.

    Measurements under the same name are added together.

  26. val repr: InMemoryStatsReceiver

    Specifies the representative receiver.

    Prepend namespace and namespaces to the names of the returned StatsReceiver.

    For example:

    statsReceiver.scope("client", "backend", "pool").counter("adds")

    will generate a counter named /client/backend/pool/adds.
