How can I tell how much heap space is actually in use by a node?

How can I tell how much heap space is actually in use by a node? If I pass in ...
set memory=1024m
set java_opts=%java_opts% -Xms%memory%
set java_opts=%java_opts% -Xmx%memory%...then memory usage starts high and stays there. I feel like I don't really know how close I'm getting to exhausting my cluster's memory as I insert objects.
Thanks,
Andrew

Hi
+(With apologies if I am misreading the question and thus answering the wrong one.)+

How much disk space is my database using?

I've totally forgotten (or never really knew) how to query the database to determine how much disk I'm using.
Can anyone send me a select statement that will give me some stats?
Thanks in advance.

How much hdd space does mac os take up?

This is an odd question, but I'm going to be getting a mac book soon. I'm going to school to be an audio engineer and I want to get a mac so that I can run pro-tools easily. I'm looking at getting an 80gig hdd, but I'm not sure it will be enough. So I wanted to see if anyone could tell me how much disc space is taken up by mac os. So, if you have a mac book with a 80g hdd, how much hdd space was actually available when you turned it on for the first time?

Hi Daniel -
First off your 80G is going to be a few gig less because that's the reality of any drive. The base install of Tiger is around 3-4Gig. If I were you (and I believe most here would second this) I'd do a 'Custom' install and install only the application you know you are going to use. You can also delete language packs that you'll never need and printer drivers as well.
Your Macbook comes fully loaded out of the box ....play around with thing to see what you like and what you might need - then do a clean install tailored to you liking.
Depending on what you do with your audio - a bigger drive can be handy, but then an external drive may be a better choice to both record to and store info on.
80Gig may sound smallish compared to todays drives - but I think you'll have a hard time filling it up unless you start working with lots of video/graphic information.

How do I find out how much storage space I have left on my macbook? can't find info in my "About this mac"

How can I find out how much disk space I have free?

I want to download a large file from the internet (22.21 GB). I have deleted everything on my computer that I don't think is necessary to keep, but how do I find out exactly how much disk space my computer has free so I can download?

Hello again Rolanda,
Barry is right on the money here ( Hello Barry! )
You need to delete / remove some files off that computer as soon as possible. Start with things you never use. Then onto things that can easily be replaced.
I would not even attempt to copy to CD's until you have at least 5 or 6 GB free!
Post back if you need more.

HELP!!! - can i somehow tell my program how much percent of the CPU to use?

can i somehow tell my program how much percent of the CPU to use?

Yes but that doesn't mean that it is only going to
use, for example, 10% of the CPU. It just means it
won't use as much, maybe, as some other process.The
answer is no.In my previous reply I made the assumption the OS
wanted one program not to "hog" the processor. The
normal way to deals with this is to use priorities.
But the answer is still yes. The answer, in terms of the question, is still no.
The OS can, or nothing
would prevent an OS from, also putting restrictions on
a program and say it may never claim more than 1/10 of
the availible CPU time.I know of know OS that has any tool that allows one to set an application to use a percentage of the CPU.
I can't even imagine a business need for it except under some obtuse testing (and only testing) conditions.

How much disk space for RT OS

Hi all
RT OS (Desktop) has a problem: If disk is full RT OS won't start.
So I have to limit the amount of file output of my RT application to a reasonable value.
To do this I read free disk space at start of my application (using GetFreeDiskSpaceEx), so I can enshure that MY apllication will not write more data than available space (e.g. by deleting old data).
But I don't know how much disk space the operating system will need while running.
Can anybody tell me a value to calculate with?
Many thanks in advance!

Solved!
Go to Solution.

A general rule of thumb is that the OS needs roughly 25MB of storage for temporary files, .ini files, persistent storage, and the like. Don't suck your usage below 25MB and you should be able to minimize your surprises.
NOTE: This number was obtained empirically via not-so-stringent testing. Your mileage may vary.

How much free space do I have on Creative Cloud?

How much free space do I have?

I'm running Snow Leopard 10.6.8 and want to upgrade to Yosemite, which requires about 5.7 GB. When I go to About this Mac, I see that I have 4GB memory. But to upgrade I think I need 5.7 RAM. I don't know difference between GB in memory and RAM. How do I find out how much free space I have and if it's enough to download Yosemite? I have 2.4 GHz processor speed for my MacBook 7.1. Also, first time I tried downloading, I ran out of gigabytes from my broadband account. I bought more ( 6 GB) and then the downloading stopped and never completed? Could I have run out of gigabytes on broadband account again?
RAM is different to disk space. Niel's #2 instruction tell you how to check disk space. That is where the installer will be saved when you download it.
Make sure the disk has well over 20-30GB free, the OS can perform badly if you fill the disk too full.
Since you have 6GB a 'cap' on your downloads I'd strongly suggest that you do the following if you ever manage to download the installer…
Wait for the download to complete, when the large window pops up prompting you to install OS X click Cancel.
Now open the Applications folder, find the installer (called 'Install OS X Yosemite'). Copy that to another disk for safe keeping.
When copied you can open the installer application from the Applications folder & continue to install OS X.
The reason for making a copy is because the installer will delete itself after installation. If you ever need to re-run it you will need to download it again. This is not good when you have a download limit on your internet connection.
Do you have access to any other internet connections? A friend, relative or business that has no download cap? It could be expensive to keep hitting your cap.
P.S. The installer may restart instead of resuming the download, so it is possible that the entire 5.7 GB will need to be downloaded again.

Finding out how much root space does each app take...

Hello! I was wondering if there is a way to find out how much root space does each installed app take, like a X-terminal command or something? Just want to figure out if i have some "non-optified" programmes (I believe this is the right term, but could very well be wrong) Cheers

Thaaaaats better
Wow.. MC is a freaking space hog! 5meg of root space
libmagic is interesting.. not sure what needs that.. it's used by software to tell what file type a file is.. it can look at a jpeg, for example and tell you it is a jpg.. clever stuff really (it doesn't use the file extension like windows) so I assume this is possibly midnight commander too..
Out of all the extra packets you've installed, they're using 19,184,792 bytes of root space.. 18meg..
5meg is midnight commander, 3 meg is QT3 support (not sure why you have that) and another 1.3meg is libmagic and 2 meg is some Python stuff..
Killing off midnight commander would free some space... (why this isn't on /opt, I don't know) but realistically you've not used too much.. you should be fine!
---edit---
I finished re-reading your post, not just the log file.. HA!! The funny thing is, doing this command line stuff is second nature to me.. I frequently do it in my sleep The N900 is therefore the ideal phone for someone of this disposition.. I need to find out blah statistics.. erm.. COMMAND LINE
If you want to wander down such a particularly perverse path, I'm happy to help out and newbieness is always forgiven
But it just shows what you can get away with using nothing more than litterally a few command line commands! pretty neat really!

How much disk space is needed to run Boot Camp using Windows XP?

But you can't install XP if you have a new Mac.
Try running XP in a VM or aquire Windows 7 which is the only one supported now.
And you will need more like 60GB for Windows 7, so I would skip on 20GB just to be safe.
20G is a fine minimum for XP, I was not responding to any inquiry about Win 7.

How much usable "space" does a MacBook Air start with?

I am contemplating purshasing a MacBook air and would like to know how much "useable" space it starts with. I know there are two options for storage (128GB and 256GB) but I would like to know how much of that is left after a base installational of Mavericks.
Also, is there a resource that will tell me how much space common apps will take up? (Numbers, Pages, etc)
Thank you

How much free space do I need to have on my 32GB iPhone 3GS?

How much free space do I need to have on my 32GB iPhone 3GS for optimum performance? I have only 4 GB left and I am worried that performance will soon be degraded.

Apple allocates space on the flash memory for cacheing proposes. You shouldnt worry. You can fill it up with out preformance problems.

How much free space before updating iPad to 5?

I have an original, 64gb iPad One.
from what I am reading here, free disc space seems to be important before doing the upgrade.
how much free space do those of who have updated suggest, BOTH on then iPad, and on
my PC hard drive?
Not looking forward to a bricked-install

The more stuff you got, the longer the whole update will take...increasing the chances something might not go smoothly.
So delete movies/videos first as they take up the most space. You can copy them back later. It's worth the small hassle imo.

Read this Apple document about the iCloud Photo Library: iCloud Photo Library FAQ - Apple Support
The following is from that document:
Can I use iCloud Photo Library to save space on my device?
iCloud Photo Library automatically keeps all your photos and videos in the original, high-resolution version. Follow these steps to choose how you store your photos and videos on your device:
In iOS, tap Settings > iCloud > Photos or Settings > Photos & Camera, then select a storage setting.
In OS X, click Photos > Preferences > iCloud, then select a storage setting.
If you turn on Optimize [device] Storage, iCloud Photo Library will automatically manage the size of your library on your device, so you can make the most of your device's storage and access more photos than ever. All of your original, full-resolution photos and videos are stored in iCloud while device-size versions are kept on your device. You can download the original photos and videos over Wi-Fi or cellular when you need them
The bottom line is that you'll still have some copy of your photos on your hard drive but they can be smaller, optimized versions.
