make_hook() [1/2]

template<class Handler >

Hook beast::insight::Collector::make_hook ( Handler  handler )

inherited

Create a hook.

A hook is called at each collection interval, on an implementation defined thread. This is a convenience facility for gathering metrics in the polling style. The typical usage is to update all the metrics of interest in the handler.

Handler will be called with this signature: void handler (void)
