I'm going over the StoreAndForward system tags and each StoreAndForward folder has LocalCache and MemoryBuffer folder. Each of these folders has TakeMetrics, StorageMetrics, and ForwardMetrics. Which one of these folders represents DB storage throughput? I thought it was ForwardMetrics, but when I sum them from MemoryBuffer & LocalCache, it doesn't match what I see on the gateway status page. What does each of these three folders represent?
