[0.90] MemoryUsage [v1.20 - 2015.02.19]

[Malah]

If you don't want an external executable to show the memory usage of KSP, now, you can use GCMonitor

Hello, I've made a little plugin to see the real memory usage of KSP on KSP.

First of all, this plugin is a little bit more difficult to use than other mods because it need the use of an external executable to back up the amount of memory used by KSP.

This is needed because for security reasons, the functions which work with others software are blocked by KSP. I know that there is a better solution to make this (without an external executable) but this would say that I need to break the security made by Squad. I have not the skill to make this and I don't want to see a malicious mod which use what I've done. For this I've choose a simple solution: have an other executable

What is it?

MemoryUsage is a plugin which adds the possibility to see the memory usage, the cpu usage and the count of threads used by KSP.

How to install it?

Unzip all files. Put the files which are in "Kerbal Space Program" folder in your game installation folder.

How to uninstall it?

Delete the MemoryUsage folder in your KSP/GameData folder and MemoryUsage.exe which is in your game installation folder.

How to use it?

To use this mod, you need to launch MemoryUsage.exe, if the game is not launched, MemoryUsage.exe will launch it. After this, in game, you just need to push on F11 to start seeing the KSP memory usage.

You can see the min/avg/max data if you hold F11 5 seconds.

If you want to launch the game in 64 bits, just put -64b in arguments: MemoryUsage.exe -64b

If you want to launch the game with opengl or anyother options just put it in arguments: MemoryUsage.exe -force-opengl

If you launch MemoryUsage.exe after KSP, you don't need an argument.

How does it work?

MemoryUsage.exe will backup the KSP memory on a file (KSP/GameData/MemoryUsage/Memory.txt) and the mod will read it, this is as easy as this.

Troubleshooting?

I have tested it only on linux 64b and windows 7 32b, I don't know if that will work on mac (I think it will not work, I need a tester).

If you are on linux and you want to launch KSP by MemoryUsage.exe you will need to launch MemoryUsage.exe with the option that you use to start KSP (ex: LC_ALL=C ...).

Perfect! Downloading NOW.

Very useful, thanks

Genius. KSP more than often crashes when I AltTab to check TaskManager. Downloading in the morning!

Being able to see which addon uses how much memory has been a wet dream of mine for a long time.

But since this thingis mostly external, I guess it can't do that at all

[Misucat]

Very great job, thank you!

How I launch MemoryUsage.exe on Linux? When I launch it, terminal appears, says "Loading..." and "Idle exit" and then closes.

How I launch MemoryUsage.exe on Linux? When I launch it, terminal appears, says "Loading..." and "Idle exit" and then closes.

On linux you need to have mono installed.

Ubuntu: http://packages.ubuntu.com/search?keywords=mono-complete

Debian: https://packages.debian.org/stable/cli-mono/mono-complete

Arch Linux: https://www.archlinux.org/packages/extra/x86_64/mono/

(I haven't all repo for all distrib, but I think you can search with your prefer tool)

I've test it on Arch Linux with mono 3.10.

In command line you just need to write (in the directory where you have put MemoryUsage.exe) "mono MemoryUsage.exe" or "mono MemoryUsage.exe -64b" (if you want to launch KSP in 64 bits). I haven't try to launch it with wine or something like this.

By default, MemoryUsage will check if it is installed on the right folder and if KSP is launched.

If KSP isn't launched and MemoryUsage is not installed on your game folder, MemoryUsage will wait 60 seconds to see if someone launch KSP. If you don't launch KSP, it will automatically stop after the 60 seconds with this message "Idle exit".

For example, for a steam installation, you need to put MemoryUsage.exe in "~/.steam/steam/SteamApps/common/Kerbal Space Program/MemoryUsage.exe".

And, if KSP.x86 or KSP.x86_64 have been renamed, MemoryUsage can't work !

I'm getting the following message:

MemoryUsage can't work work! You need to Restart MemoryUsage

But restarting doesn't work. I'm using Windows 7, Direct3D and many mods including Active Texture Management.

Any known fixes?

Did you launch the MemoryUsage.exe ?

[FreeThinker]

Did you launch the MemoryUsage.exe ?

Apparently not. I though MemoryUsage was automaticly started by the Plugin. After I start it manually, it seems to work as it should

For security reason, KSP can't launch an external executable.

Oh, I though you said it did.

if the game is not launched, MemoryUsage will launch it

It confused me into thinking the plugin started the exe automaticly

I've corrected it:

To use this mod, you need to launch MemoryUsage.exe, if the game is not launched, MemoryUsage.exe will launch it.

This looks very useful! I have always wanted an easy way to monitor my CPU and RAM usage, thanks!

[FreeThinker]

Could you please add some warning system that is triggered when memory is running out (near 3.8 G). When the alarm is triggered, the Text could become red or flashing and an alarm sound should be heard.

This is a good idea, I will add this for a next update, thanks (with options to disable it ...).

Good to hear this mod will become better,

One question. what is the difference between physical memory used by KSP and vurtual memory used by KSP?

Also, you say you basicly copy the contents of KSP memory. Beside copying, can you also modify it, let's say, free up some memory by throwing away textures ...

One question. what is the difference between physical memory used by KSP and vurtual memory used by KSP?

The physical memory is on your ram and virtual memory is on your hard disk, the virtual memory extend your ram but it is slower.

If you need more info:

Also, you say you basicly copy the contents of KSP memory. Beside copying, can you also modify it, let's say, free up some memory by throwing away textures ...

No, this mod couldn't do this, because this mode does not really interact with the memory of KSP. It just goes to read the total memory used by the software this is only a number in byte If you search a mod which can make this, you can look: Loading textures only as required but it is in an experimental release!

Don't get discouraged too easily. I plan to run some extensive testing with this nifty little utility. I'll load KSP stock-only, and record the baseline footprint. Then I'll load my first mod, record the size, and calculate the footprint difference from baseline. Then I'll uninstall that first mod, and individually install a second mod, record the size, and calculate the footprint difference from baseline. Then I'll reinstall the first mod alongside the second, record that size, and see if the resulting footprint corresponds to those two mod's footprint differences combined. If they match up, I'll consider the process proved.

Note, however, that plugin-heavy or plugin-only (mods light on parts) tend to have very "bursty" or variable memory consumption, and typically idle at levels much lower than during flight. Malah, do you have any ideas how to track this in-game?

Otherwise, thanks for a truly utility! It purports to fill a VERY longstanding need.

Hello, I think that you can see it with GC functions, sarbian has made a plugin for this, but I haven't tried it: GCMonitor

Nice catch! Downloaded, and will install shortly.

Hello, MemoryUsage work fine on KSP 0.90
