目前小弟正在做關於VMware監控指標的資料時，找到了下列關鍵指標

• Consumed
• Overhead Consumption

參考了《vCenter and Memory metrics》

(來源：《vCenter and Memory metrics》)

The first section is the host memory:

Consumed (1.36GB)
Overhead Consumption (42.00MB)
Again, Consumed is the amount of machine memory currently allocated to the VM. In other words, out of the 2GB provisioned currently 1.36GB is being consumed by that VM. The Overhead Consumption is the amount of memory being consumed for the virtualization overhead, as you can see it is less than what the VMkernel expected to use as mentioned in the first screenshot. I guess you could do the math easily:
Consumed = Private + Overhead Consumption

看完整篇後，其實我對這兩個metrics 還是相當不清楚含義的

1. 仍不太清楚，監控這兩個指標的主要原因
2. 也不清楚，這兩個指標的上升，會對VM有什麼影響
3. 是否有更淺顯易懂的方式解釋這兩個指標
