// package runtime implements the work-in-progress conventional runtime metrics specified by OpenTelemetry.
//
// The metrics produced are:
// runtime.go.cgo.calls - Number of cgo calls made by the current process
// runtime.go.gc.count - Number of completed garbage collection cycles
// runtime.go.gc.pause_ns (ns) Amount of nanoseconds in GC stop-the-world pauses
// runtime.go.gc.pause_total_ns (ns) Cumulative nanoseconds in GC stop-the-world pauses since the program started
// runtime.go.goroutines - Number of goroutines that currently exist
// runtime.go.lookups - Number of pointer lookups performed by the runtime
// runtime.go.mem.heap_alloc (bytes) Bytes of allocated heap objects
// runtime.go.mem.heap_idle (bytes) Bytes in idle (unused) spans
// runtime.go.mem.heap_inuse (bytes) Bytes in in-use spans
// runtime.go.mem.heap_objects - Number of allocated heap objects
// runtime.go.mem.heap_released (bytes) Bytes of idle spans whose physical memory has been returned to the OS
// runtime.go.mem.heap_sys (bytes) Bytes of heap memory obtained from the OS
// runtime.go.mem.live_objects - Number of live objects is the number of cumulative Mallocs - Frees
// runtime.uptime (ms) Milliseconds since application was initialized
