This change adds four additional metrics to the runtime/metrics package to fill in a few gaps with runtime.MemStats that were overlooked. The biggest one is TotalAlloc, which is impossible to find with the runtime/metrics package, but also add a few others for convenience and clarity. For instance, the total number of objects allocated and freed are technically available via allocs-by-size and frees-by-size, but it's onerous to get them (one needs to sum the sample counts in the histograms). The four additional metrics are: - /gc/heap/allocs:bytes -- total bytes allocated (TotalAlloc) - /gc/heap/allocs:objects -- total objects allocated (Mallocs - [tiny]) - /gc/heap/frees:bytes -- total bytes frees (TotalAlloc-HeapAlloc) - /gc/heap/frees:objects -- total objects freed (Frees - [tiny]) This change also updates the descriptions of allocs-by-size and frees-by-size to be more precise.
