Performance - What does good look like?

[atkin]

Hi,

I'm looking at these performance graphs and I'm unsure what they mean...

Am I using 10% of the available performance or 110%.

How do I best monitor the performance of this system?

I've copied all of the graphs here:

Thanks in advanced for any guidance

I'm trying to understand what good looks like in regards to the performance of my storage device running Open-E.

These are the graphs I can see - but I dont know how to understand them - is the 10% of the total available performance of 99% ?

It is showing you the amount of writes to the sda (RAID array, Volume Group or your storage) device on your system.
to convert the KB to MB/S, each sector is 512 bytes, and 512 bytes equal 0.5 KB. Your showing an average write of .71.
