Member Function Documentation

name()

virtual std::string const& beast::insight::Group::name ( ) const

pure virtual

Returns the name of this group, for diagnostics.

Implemented in beast::insight::detail::GroupImp.

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)
