About proccessor usage

How I can find out in my Java application current level of processor usage?
Does anybody know such packages?

It is usually sufficient to employ your operating system's facilities to monitor / meausre such things. In X-nix, you can use the time(x) program to find out how much user cpu time, system cpu time and real time a process used.

This makes a difference. What does it say in Settings > General > About?

HT4623 The software update option is not on my phone. It just goes from "about" to "usage". I have an iPhone 3G. Every time I try to update it on iTunes, nothing changes. I have version 4.2.1, no matter what I do. Any suggestions?

I have an iPhone 3G, and cannot update my iOS. In the General tab, "Upadate Software" is not even there. It just goes from "About" to "Usage". When I try to update on iTunes, it always remains the same. iOS 4.2.1. Any suggestions? (My PC uses Windows XP). Also, my WiFi has completely quit working. Works fine on the other iPhones in the house, as well as the XBox 360, so I am sure it's my phone. I tried everything I could think of, including restoring the iphone to factory settings & then updating, but no luck. Thank you! for any help you can give! I plan to get an iPhone 5, but wasn't ready to do it quite yet. Hopefully my phone can be rescued until I'm ready.

That is the highest you will be able to go with 3g. You need 3gs or 4 to go any higher (multi processors and more memory needed). Version 4.2.1 marks the end of your updates for that device.

HT4623 When we go to Settings General, we do not have an option for Software Update...only About and Usage.

When we go to Settings>General, we do not have an option for Software Update...only About and Usage. How do we update the system on our iPad?

If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.0.1. For the iPad Mini the iOS is 6.0.2. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily. Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update an iPad (except iPad 1) to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).

It sounds like something on your phone keeps eating up your available space. I recommend you use the Usage section of settings to help identify what app is taking up this space so you can investigate it further within the app:

Tap Settings > General > Usage to view the amount of space each app and its content takes on your device.

HT4623 I am trying to update my ipad to iOS 6, but I don't have at the Software Update option. My only choices are About and Usage

I am trying to update my iPad 2 to iOS 6, but I don't have the Software Update option. I only have About and Usage. How can I update?

In order to update from an IOS earlier than 5.0, you have to hook it up to the computer you sync with to do so.
Once you have updated, you will see the software update option on your settings. But this feature was not introduced until 5.0...

Settings General About Diagnostics & Usage Diagnostic and Usage data

Settings > General > About > Diagnostics & Usage > Diagnostic & usage Data.
Everytime I look Diagnostic & usage data I see full of crash reports such as Log-aggregate, LowMemory, assistivetouchd and etc... This crashes/crash report should be the reason why my ipod touch 4th gen is slow, sometimes hangs for a second and sometimes crash apps. I already tried to reduce the memory usage to 50% and momentarily double click home button to remove the applications running at the back but still crash reports are adding and reach about 100 and still increasing! Please help me to solve this problem. Maybe give me a tip on how to avoid, minimize or remove this crashes / crash reports on my ipod touch. thank you.

HT4623 I am trying to update my iPad,but when I go to settings general I do not have an update software to click on...... Only about then usage?

I am trying to update my iPad 2,but hen I go to settings/ general, there is no update software to click on! It goes from about to usage?

There are countless posts about this. There's a problem at Apple's end and has been so for several days.
However, I have no trouble updating using itunes on my computer and later syncing to my device.

HT4623 How do I update if my iPad does not have the software update button in between about and usage?

How do I update my software to iOS 5 if I do not have the update software button in between about and usage in my general settings?

You'll need to connect the iPad to a computer running the latest version of iTunes. If the computer does not belong to you, make sure you create a backup (not a sync) before installing the update.

HT4623 My iPad 2 does not say software update between about and usage in gerenal setting anyone know why this is

My iPad 2 does not say software update between about and usage in general setting anyone know why this any help welcome thanks

Keith. Look in settings, general, about. About halfway down the screen is an entry labeled version. If it is anything lower than 5.0, then you wil not get wireless updates. You need to plug your pad into your computer that you set it up with which is running the current version of I tunes to get the update.
When you plug it in to i tunes, be sure to do a backup. Also, the machine will ask if you want to transfer purchases. Tell it yes. This saves your content and purchased apps and music to your iTunes on the computer. When you do the software update, it will then reload that material onto your pad.
If you have taken any pictures on your pad, be sure to upload those to I photo, or whatever photo library you are using so that they are not lost when you do the upgrade.
Once you get to the current version, any future software updates can be done over the air, not requiring you to use the computer. That feature was enabled with version 5. But it is a good idea to do backup and syncs with your computer from time to time.

Question about CPU usage for video playback

I've asked a related question already on the Safari forum, but would like some clarification, please.
The speed of this iMac is 400 MHZ and whenever I go to YouTube or almost any other site that requires video I see that the CPU usage can peak way up at 80% or more. I have Flash 9 installed which has a minimum of 500 MHZ, so I get pretty choppy video, but that's not the issue here. I can live with that. I keep any other applications closed. I'm often running a small fan over the top of the iMac to help vent the buildup of heat. I can monitor the temperature at the Hard Drive and I suppose that gives me an idea, of sorts, about general temperature conditions inside.
The answer I got was that this kind of CPU usage could be detrimental to the processor as it builds up excessive heat and to keep this kind of video to a minimum.
My question is can anyone roughly suggest what a maximum time on YouTube, for example, would be, 2 minutes, 5 minutes, is 10 minutes too long? I have plenty of RAM at 768. Some guidelines?
Thanks.

Hey WZZZ,
Thanks for the star and kind words.
I'm the de facto Mac guy at my kids' school and we have around 25 iMac Slot Loaders working there. You can imagine they get abused quite a bit. There are 10 running Garage Band in the Music Department. That puts a tremendous strain on the CPU and I'm actually surprised that they run it so well. My son had a 600 iMac running GarageBand, he was complaining that it was getting jumpy and when I looked at it he was running 10 unlocked tracks simultaneously! So now he has an eMac G4 800 and that of course runs a lot better.
So to sum up, with all the abuse of those machines in terms of the CPUs the problems I have with them have nothing to do with that. The problems have more to do with parts of the OS that they toss, headphone jacks abused, CDs jammed in the slots, and the like.
A couple of other related things. I've got Hardware Monitor, demo, installed and I think it reported it could only find the hard drive sensor, if I'm not mistaken - nothing else on this Mac with a sensor. Is that right?
I see references to CPU sensors on 400 iMacs but on the 400 I have here for repair Temperature Monitor reports no sensors. Perhaps there were different versions of the 400.
But very good to hear that the fan is a good idea for CRT related things. Should I keep the fan running-mostly for that hard core CRT stuff- even if the computer is sleeping and the room temp. is only around 62-64 F.? (We need to put on warm clothes to sit in front of this thing now, but worth it to keep this old machine happy).
On the one I did the fan pushed the airflow in the direction of the passive flow of the iMac - in at the bottom and out the grill by the handle.
One more question, more out of curiosity than anything else: If I move this small clip-on fan close to the case - right now it's about 3 feet away and the image is stable - the screen begins to flicker and flutter quite a lot. My theory is that that's happening not necessarily because of electro-magnetic interference from the fan motor, but rather, because the back of the tube is getting cooled unevenly. What do you think?
Well the classic failures that I see in the iMac are in this order:
1) Dielectric breakdown of the flyback transformers internal insulation. This is heat/age related and a common problem with CRTs in general.
2) Breakdown of high voltage electolytic capacitors and regular high voltage capacitors on the neck board and PAV supply.
3) Solder problems with the flyback itself. This is diagnosed by the upside down boot technique.
I used to repair these problems but now it's easier for me to swap the Firewire boards into working 350s. I've got 12 of those in the basement currently.
