Declared in `<balm_defaultmetricsmanager.h>`

Create a scoped guard which invokes the `DefaultMetricsManager::create` method. Optionally specify a `basicAllocator` used to obtain memory. If `basicAllocator` is 0, the currently installed global allocator is used. The behavior is undefined unless `0 == DefaultMetricsManager::instance()` prior to creating the guard. Note that the default metrics manager instance is not configured with a publisher; clients must create a `Publisher` object and add it to the default metrics manager in order to publish metrics.

Create a scoped guard which invokes `DefaultMetricsManager::create()` to create a default metrics manager instance that is configured with a stream publisher that will publish collected metrics to the specified `stream`. Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed global allocator is used. The behavior is undefined unless `DefaultMetricsManager::instance()` is 0 prior to creating the guard.
