a simple describing identifier that is unique per sentry chain, e.g. "rateLimit".
ResourceName plus sentryType uniquely name each sentry. The sentry registry
enforces this. The sentryType is also used in JMX to uniquely name bean properties
for a resource.
null for sentry wrappers, that must not be registered.

number of concurrently allowed invocations

Append a invocation duration limit sentry to the current sentry.
Append a invocation duration limit sentry to the current sentry.
WARNING: do NOT use this sentry when you invoke it from 1) a akka.dispatch.Future or 2) an akka.actor.Actor. For such circumstances you are MUCH better of with a timeout on the enclosing future or a timeout message within the actor. Reason: this sentry blocks the current thread while waiting on a future that executes the task. Blocking the current thread is an anti-pattern for futures and actors.

Append a circuit breaker sentry to the current sentry.

Append an extensive metrics sentry to the current sentry.
Append an extensive metrics sentry to the current sentry.
Four timers are registered: "all", "success", "fail" and "notAvailable". These are update for respectively each invocation, succeeding invocations, invocations that throw an exception, and invocations that are blocked by a sentry that is later in the chain (detected by catching NotAvailableExceptions).
When 4 timers is too much detail, use .withMetrics instead.

One timer is registered: "all". It is update for each invocation. For more extensive measuring, use .withFullMetrics instead.
