a string describing the resource that is protected, e.g. "mysql:server-b.com:3336". It is used in exceptions and visible through JMX.
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.
Sentry that collects metric of invocations. A new instance can be obtained through the SentrySupport mixin.
The following metrics are created:
- timer "all" for all invocations - meter "notAvailable" for invocations leading to a NotAvailableException, e.g. all invocations blocked by a sentry - meter "fail" for other failed invocations
Note that in other to make effective use of the "notAvailable" meter, this sentry must be the first sentry in the chain.
This sentry can not be used in the same sentry chain as the TimerSentry.
