Are there any metrics when this buffer (`indices.memory.index_buffer_size`) is filled up? The refresh interval for my index is 5 seconds, but I think that due to the volume + document size, the buffer is filled up earlier than that and it is flushed out.

Also, when the buffer is full, does it create in-memory segments or it actually write to the disk?
