Summarize memory blocks and total consumption

[PizzaProgram]

Description of the feature, modification, idea or suggestion

I'm currently trying to track a memory leak in my app, and System Informer is a great help to do that. Except that I have to calculate 1000+ lines of memory block consumption one by one, when I select them. It would be great to:

Summarize the selected lines at "Memory" page and show at the bottom.

Even more important would be, to

Show total memory consumption at Status page

• Total size
• Total delta
• Peak total

Because private memory allocation alone is not enough to measure, if the app is reaching a total of 2GB and crashes.

Maybe consider to add a checkbox Graph to the "Performance" page too, to:

• Show total memory consumption (private + virtual)

Optional:

• Memory fragmentation statistics

Proposed implementation details (optional)

It would be great, if the "Total bytes" memory consumption would be calculated the same way as VMMap does from Sysinternals.

the "Total bytes" memory consumption

"Total bytes" are under the I/O category for disk/network and unrelated to memory usage?

Sorry, but I don't understand this question. I'm talking only about memory consumption. VMMap is a memory-usage monitoring app too. I've never mentioned anything about I/O nor disk/network.

I've added this line:

only for the reason to my original request, because maybe "simply summarizing private bytes + virtual bytes" is not the correct way to calculate "total memory consumption" ...

"Total bytes" is the name of disk/network statistics 🤷‍♂️

The values down the left column?

or the values across the top row?

maybe "simply summarizing private bytes + virtual bytes" is not the correct way to calculate "total memory consumption"

The total would be Private bytes + Private WS + Shareable WS + Shared WS?

VMMap and System Informer are querying the system at different intervals and the program or the system changed a small number of pages between those intervals but otherwise the totals the same?

Total size memory = Total bytes memory It does not really matter, how we call it. It can be the very same "naming", the only thing that matters, where is it listed. _(Whether under "I/O" or under "Memory") The different size/byte naming is currently confusing.

IMHO to be consistent everything should be listed like this:_

• Private (bytes)
• Private delta (bytes)
• Total (bytes)
• ... etc
• Page faults (count)
• ... etc

So the unit could be separated by a sign. Also "Private [bytes]" is ok. Than we wouldn't need to thing about if "byte" or "size" is better.

The values down the left column?

YES, but I don't think it would be necessary to list all those values. Also maybe it would consume too much CPU to collect those separately. (Sadly I know very little about memory consumption procedures to know how they are counted, which data can be easily obtained from OS, etc...) I can reflect only as "end user" to the fact that: "Total memory consumption" is missing from the list.

The total would be Private bytes + Private WS + Shareable WS + Shared WS?

I'm not sure. Can we ask the programmers of VMMap? If I count together those columns, they do not match. (For example the "Shareable" blue line: 12700+2216 != 24884)

Answer v2.0:

The total would be Private bytes + Private WS + Shareable WS + Shared WS?

Sorry, If you have ment by that the System Informer's total, than than the answer is: No If I summarize 109+67+25+11 = 212MB .. even if I would add Working set +92 = 304MB, is still much smaller than 349MB real total consumption calculated by VMMap.

So something is missing... But I don't know what.

VMMap Size column includes blocks of reserved but uncommitted memory. That isn't displayed in the Statistics tab in System Informer. But if you can see reserved memory in the Memory tab:
