Any way to get the Memory Graphs to properly show data in Gigabytes?

Hi,

When I go to the Memory graphs, the numbers don't match exactly how I'd like them to.

For example: 

I have a server in vCenter that has 128 Gigs of RAM.

When I look at the Memory Graph, This server says 125.26G RAM but the graph is at around 135G of RAM.  If I look at the Raw Data tab, the MemTotal is listed as 134497869824.  This matches where the line on the graph is, but doesn't match what's in the pop up window or at the bottom of the graph.

If I take 134497869824 and divide it by 1024 a few times, I do end up with the 125.26 number, but it's a bit confusing when the graph number doesn't match the actual number.

If I go into the Graph definition and Turn Off the Scale by units of 1024 option, then the numbers underneath the graph change and will match what's on the graph, but then the numbers are inflated.

 

We're going through a project right now to find VMs that have more memory than they need and determine what to reduce them to.  I'd like to easily just look at the graph and see how much they're using so I'd like it that when I have a VM that I've assigned "128" Gigs of memory to, I'd like the graph to have the MemTotal line at 128.  Is that possible?

Does everyone else use the graphs with the slider on or off?  Has anyone else been confused by this or is it just me?  ;)

    Hi,

    Yeah..it looks confusing. This is what we are doing atm..since graph uses a default scaling of bytes to GB in a manner that fits the data within the graph range. When the Scale by units of 1024 option is turned off, the graph uses raw bytes, which can inflate the memory representation in the graph.

    So, we have the max y-axis value to 128GB manually and it will lock the graph..

    Hope this helps
