Is it possible to get memory usage stuff?

is it possible in java to get % of memory usage of my computer. hard disk free space, computer specs and etc??
thanks.

Not easily and not in a cross-platform way. If you absolutely have to get that stuff, you'll have to use JNI for most of it. Google or search this forum, this question has been asked many, many times before.

Getting memory usage details in ABAP program

Hello,
Is there any method to get the memory used by the program and control the program like restricting the memory usage to some limit or any other control measures which can be taken in the program itself if the memory usage by the program exceeds a maximum limit. Or kindly let me know where i can find the details.

Get Memory Usage

I need a suggestion for a light weight tool that will show the memory usage and also that can tell me which components are using more memory than others. I tried using JProfiler from my server but it is so slow to display the GUI on my machine. Something that's fast and good.

I was finally able to connect remote session to local JProfiler. Java app runs on HP box. Now after running my code through the profiler I see that only 200 MB of heap space is being utilized but when I run top command I see 200 MB of RES space and total size is 1 GB. I tried to look at profiler but can't see where it's using extra 800 MB of memory. This application extracts blob and then encrypts them and writes to the file system. There are 4 threads that extract different kind of data.

How to get memory usage of the JVM...

Hi,
I want to know the total amoutn of memory used by the JVM, while I am doing some particular transaction over my web application.
One way is to use the methods in java.lang.Runtime. But the output seems to be fluctuating to a significant extent.
Is there an alternative way to accomplish the same.
TIA,
Basu.

Complie with the setting -verbose:gc,
whenever the GC runs, it prints out the acutal amount of mem originally used, the amount used after GC and the JVM mem usage.

Memory usage problem with TDMS files

Hi,
I have used TDMS write file to save my real time data . I need to leave my VI, running for a long time (even one day ) then I process the acquired data in a seperate vi.
My problems are
I olways get memory usage message during data acquization. Also even if I finish acquization ( for example make a 2GBytes TDMS file I get the same message when I want to try to read it.
To read the TDMS fisrt I open ,configure ,read and then close the TDMS ref.Then I use the data from the TDMS as input to my loop.
By using this method I olways get (Memory usage message ) and I need to stop the process loop. Would you please help me how can I avoid this problem

your problem is the attempt to attach all the data in one big goo in memory. A 2GB TDMS file needs probably a little more than 2GB in memory if you want to read all its contents at once. That is BAAAD! You should try to write your analysis in a way that can read the data in smaller chunks and process each chunk individually instead of trying to load the entire GIGA blob at once. Computers can have a lot of memory nowadays but that does not mean that you should attempt to operate on GigaByte data in memory in one go.

SA520W - High memory usage, possible fix in 2.2.0 firmware?

As suggested by Thomas Watts, I'm starting a new thread to discuss the new SA520W firmware (2.2.0) and a possible resolution to high memory usage I'm experiencing on my network.
My current setup is: 16Mbit DSL > SA520W > SA300-10, all with stock settings (no fancy VLAN's etc.)
I have 4 CentOS 5/6 servers and a Windows 7 Ultimate station connected to the switch. I use CIFS to connect from Windows station to the other Linux servers and send large files. I currently notice the following behavior:
When the file transfer starts, the Intel 1Gbit NIC is nearly saturated, hitting 115MB/sec. After few seconds, the data transfer comes to a halt and the transfer speed drops to around 50MB/sec. If I check the memory usage before the file transfer, it is approximately to 50-60% (on a fresh router reboot). Every time I send large files to other machines, the router memory consumption increases and it does not lower after a reasonable delay. I end-up with high memory near 90% and the only solution I have is to reboot the router in order to bring it back to 50%.
Now, Thomas told me that this is simply a cosmetic issue, the memory is not actually 90% used. Yet, when the memory hits this threshold, I'm not capable to send files are normal LAN speeds I'm used to. Rebooting the router allows me to send only ONCE (and for few seconds) data at the expected LAN speeds.
I would apreciate any input from Cisco engineers as well other users who experience the same issue. I would also like to know if any related work was done into 2.2.0 firmware and when we expect to have it released to users.
Regards,
Floren Munteanu

Hi Tom,
See below the answers.
Are you currently running the 2.1.71 code?
Yes
Are you using IPS?
No, the LAN is for internal use (no external users allowed)
Are you using Protectlink services?
No
Hardware wise, I did not changed anything on machines. All boxes have dual Intel EXPI9301CT NIC's (LACP was planned) but I currently use single connections for sanity reasons (disks won't allow greater speeds anyway). Previous to Cisco, I used a Netgear ProSafe router + switch which did not encountered the issues I mention. Honestly, at first I thought I'm dealing with some stupid disk issues on Windows. So I ran a quick test and the stats are proper:

> Total Run Time 00:01:39.50
As I mentioned before, everything is pretty much stock on router/switch settings. If you have any tips that allow me to identify the cause, I would appreciate the input. What puzzles me is the speed drop and quick memory usage increase. It occurs 7-10 seconds after the transfers begins. It looks like the data transfer hangs for a very short period of time (less than half of second) and the transfer speed decreases from 110-115MB/sec to 50-60MB/sec. The transfer is completed at this speed. No matter how many other files I try to transfer after, the speed won't go higher than 60MB/sec. If I reboot the router, I get the same cycle.

Get CPU and memory usage

Hi!
I would like to know if there is any way of getting system CPU and memory usage using Java code.

I want to get the system CPU and memory usage using the performance monitor dll, the perfctrs.dll, but access this data using Java language.Then you should create wrapper dll between your java code and perfctrs.dll and convert data from format of dll to format of your java code.
So, that is next question - how to create wrapper dll, how to deal with or how perfctrs.dll works?

Memory usage gets high and stays high

I'll use my current project as an example, but I've been noticing this issue ever since I started monitoring my computer's memory usage. If I have an hour long Premiere CC timeline and render it, during rendering my computer's memory will go up to about 90%. After rendering is done, task manager shows that Premiere is still using about the same amount of memory, and it stays that way until I restart my computer. It's like it has locked into using certain resources and cannot let go. Any way to remedy this? I currently have 10gb memory (ordered 2gb more that is arriving this week), so it's not the fastest machine around, but should handle memory better in my opinion. I am fine with the rendering speed itself, it's just the tied up resources afterwards that seem like it could be fixed.
One more point - one solution is forcing Premiere and all its components to close. This gets the memory back to normal. Unfortunately, sometimes after I render a long timeline and force restart Premiere, when I get back all my render files don't properly reconnect and I'm forced to re-render the timeline. The fact that it doesn't reconnect to the render files is another related-issue I need help with too, if anyone can offer feedback. Thanks!

On the lost renders.

On the memory issue, I'm not sure anything is wrong here. You say PP releases it when you close PP. That's the expected behavior.

i've read i can disable the kernel modules that i don't need to improve the memory usage.
which modules i can disable without "kill my system"?. i don't want SATA, DVD, bluray, infrared, floppys, bluetooth, usb3.0, 3d video card, dial-up-integrated modem, ntfs, 'cause mi old is so old. i want it only for the university.
thanks in advantage for the tips, and sorry if someone can't understand very well that i wanna tell you, english isn't my "mother languaje".

thanks for the answers. yes, i have a 1 gb of swap.
i think i can reduce the memory usage of the system if i dissable the kernel modules that i don't use. but, the question is: what modules is safe to disable to get it?
thanks in advantage

I keep getting a message saying Performance alert high memory usage by firefox what can I do about this. Patricia

I have gone into the History and deleted all the pages would this help reduce the memory usage.

HELP: iPhoto 6.0.6 memory usage problem, iMac getting *slow*

Hi,
I have a 20" iMac with 2 Gig RAM.
I have iPhoto 6.0.6 with lots and lots of pictures and little movies (taken with an old digital camera) -- a "get info" on the "iPhoto Library / Originals" folder says there are 9836 items in there.
When I open iPhoto, the Activity Monitor indicates iPhoto is using 130meg real memory, 130meg virtual memory. With every "page down" in iPhoto (the thumbnails are running about 6 items across) about 50 meg of memory gets added to real memory, and even more gets added to virtual memory.
After just a few minutes of usage it now looks like this:
Real Memory: 382.43 MB
Virtual Memory: 1.18 GB
Eventually the computer gets extremely slow and unresponsive; I've seen the iPhoto memory usage as high as:
Real Memory: 1+ GB
Virtual Memory: 2+ GB
Does anyone have any suggestions for how I can fix this problem?

I have to say that the Virtual Memory numbers compare quite okay with both my Macs here, the Actual Seems slightly higher but noting spectacular. That said, the highest you’ve seen do see quite extraordinary.
Something to try:
Create a new account (systempreferences -> accounts) and make a library there. Import some pics and see if the problem is repeated there.
Regards
TD

I get daily messages stating high memory usage exists on my firefox. How do I solve this?

A rectangular box shows up once a day on lower right corner of screen. Has a graph on it and says high memory usage. What do I do to lower it?

Thanks, but answers that begin with the word "try", in my experience, are usually just vague guesses.
I found the solution on my own...
Rip out everything Firefox and Mozilla from your computer, including in both Library folders. Throw it all in the trash and empty the trash.
Then download and install a fresh copy of Firefox.
Next time, I will simply rip everything out and LEAVE it out, because this esnips crap is a longstanding MAJOR invasion, mozilla knows it, and they do NOTHING about it. WORSE, it is not possible to contact mozilla in any way. Obviously, they DO NOT CARE!! Otherwise any attempt by esnips to sneak their crap onto a computer would be spotted and INTERRUPTED by Firefox, which obviously, is not the case.
Esnips turns FIrefox into useless crap software. I recommend Googlechrome.
And why on Earth is Mozilla not suing the people who force this esnips junk on their users? Esnips is USING Firefox to sneak into Firefox cusomters' computers and take a big dump in their machines.

Is it possible to get memory usage stuff?
