This graph shows which files directly or indirectly include this file:

Classes
struct	utils::statistics::StatisticsRequest
	Used in legacy statistics extenders. More...
class	utils::statistics::Storage

Namespaces
namespace	utils
	General-purpose utilities used across userver libraries.
namespace	utils::statistics
	Statistics writers, metric types, and histogram helpers.

Typedefs
using	utils::statistics::ExtenderFunc = std::function<formats::json::ValueBuilder(const StatisticsRequest&)>
using	utils::statistics::WriterFunc = std::function<void(Writer&)>

Functions
void	utils::statistics::RegisterWriterScope (ResourceScopeStorage &scope_storage, Storage &storage, std::string common_prefix, WriterFunc func, std::vector< Label > add_labels={})
	Add a writer function to Storage (usually obtained from components::StatisticsStorage). It automatically calls utils::statistics::Storage::RegisterWriter() just after the component construction and utils::statistics::Entry::Unregister() just before the component destructor.
