Data isn't really flushed from the slog to primary storage -- indeed, the slog is never read from during normal operation. Instead data is streamed to primary storage asynchronously. This should happen within 5-10 seconds at regular intervals as transaction groups are closed. > 2) How can I monitor SLOG fullness in order to determine whether > additional capacity is required? Rather than monitoring fullness, I'd suggest you look at the datarate to the slog device.
