◆ getMetricsViewAsync() [2/2]

std::function< void()> IceMX::MetricsAdminPrx::getMetricsViewAsync ( std::string_view view,
std::function< void(::IceMX::MetricsView, std::int64_t)> response,
std::function< void(std::exception_ptr)> exception = nullptr,
std::function< void(bool)> sent = nullptr,
const Ice::Context & context = Ice::noExplicitContext ) const

Gets the metrics objects for the given metrics view.

Parameters
viewThe name of the metrics view.
responseThe response callback. The Ice runtime calls this function from an Ice thread pool thread. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function. It accepts:
  • returnValue The metrics view data, a dictionary of metric maps for each metrics class configured with the view. The timestamp allows the client to compute averages which are not dependent on the invocation latency for this operation.
  • timestamp The local time of the process when the metrics objects were retrieved.
exceptionThe exception callback. The Ice runtime calls this function from an Ice thread pool thread. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function.
sentThe sent callback. The Ice runtime calls this function when the request is accepted by the transport. When the request is accepted synchronously, the Ice runtime calls this function from the current thread and passes true as argument. When the request is accepted asynchronously, the Ice runtime calls this function from an Ice thread pool thread and passes false as argument. If you set Ice::InitializationData::executor, the executor determines the thread that executes this function in the asynchronous case.
contextThe request context.
Returns
A function that can be called to cancel the invocation locally.
