Activity Monitor - Reset?

Hi,
I'm trying to monitor memory page-outs. What I want to do is reset the counter to zero from time-to-time, in order that I can view exactly what circumstances cause page-outs. I can't see a way to reset the counter. Does anyone know of a way to do this?
David

Glad to help. Now, mark the reply, appropriately. Good computing.

Running 10.8.3 on an Intel iMac 27'. The Finder keeps grabbing over 100% of the CPU which seems to stop me from opening any folders. Only quitting the Finder from Activity monitor resets it to normal. Any ideas?

Nope, I don't have a "/Users/charon/Library/Mobile Documents" directory, let alone anything underneath it. Is that like an iCloud thing or something? I tend to avoid the Apple-supplied services when I can (I don't use iTunes either unless I can help it).
As an update, as of about two days later this problem seems to have solved itself. Possibly sleeping and waking did something to it (though that seems unlikely given how many times I rebooted), or else there was just some long-*** kernel process that finally worked itself out. But my system CPU is back down to normal and the cursor freezes are gone.

Activity monitor...how to reset?

My DSL provider has now limited me to 150 GB of downloaded data. I need to know how to reset the Activity Monitor to monitor my network download usage.

Hola Dalgor777,
There is a widget called iStat Pro that has a section (Network) that monitorize the bandwidth. I think may help you.
I see that it has been deprecated by the company: iSlayer. You can download from here.
Greetings,

Activity Monitor and Network Usage??

I'd like to get an idea of my network usage per month prior to signing up for a service plan, and I notice that the Network tab of Activity Monitor will track Data received. When or how does the number shown there get reset to zero? What would be the best way to track the network usage over a period of a week or so?

I believe the number is from your last login, but it shouldn't be too hard to test whether that is the starting point or the last restart.
Neither will help you track network usage over a specific period. For that, you will have to hunt down a utility on macupdate.com or versiontracker.com. I'm pretty sure I've seen some go by. You might search using terms like "ISP", "bandwidth", "network", and "meter".

Slow Mavericks and Activity Monitor Uselessness

The recent Mavericks update may have improved performance to some degree, but I'm still experiencing unusual slowness of apps often. One of the most irritating things is that the one app I except to help me shed light on the cause of the slowness, Activity Monitor, typically shows NO unusual heavy system load when I observe apps being slow.
For example, I click on + in Safari to create a new tab. I expect immediate response, an immediate new tab being open. Instead, it takes maybe 5 seconds, perhaps even 10 seconds. So, I immediately switch to the Activity Monitor window to see if I can identify what might have caused the slowness. I think that maybe the CPU become extremely overloaded during that brief period. But I see nothing in Activity Monitor to clue me in as to what the problem was.
To me, this means Activity Monitor is not monitoring relevant activities. I don't know why Safari is slow opening at tab, but whatever it is doing should be an activity that Activity Monitor monitors, since it obviously is something that takes the machine a lot of time to do.
Could a knowledgeable person in Apple's software department respond here and say something about why opening a new tab in Safari takes so long?

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

MBP with 10.6.8: CPU usage high, no responsible processes shown in Activity Monitor. What causes this?

After using my computer for some time, CPU usage climbs to about 90% (ca. 65% user / 26% system) and fans run at high speed, but there is no processes that seem to use CPU (other than Activity Monitor itself ~1%).
This has happened a few times recently. It happens when I've used my computer for some time, hours or a couple of days (I usually put my computer to sleep when not using it but rarely shut it down). I've tried to quit all running apps incl. Growl, Dropbox, and anything that could be responsible to this but with no results. Putting computer to sleep for a long time doesn't help, cpu usage will climb instantly after wake up. Restarting system is the only thing that helps.
Most of the time I use my laptop with external monitor, lid closed and connected to power supply. When experiencing this, opening the lid causes fans to slow down, but CPU usage remains high and battery drains quick.
Any ideas what might cause this?
My MBP is 15" model with Core 2 Duo 2,66 GHz (MacBookPro 5,3), OS X version is 10.6.8, all available updates are installed.

Perform a SMU reset.

Remove the anti-virus, it's running a root level process all the time that's taking your CPU and it's not necessary as there are no Mac viruses, Apple has the trojan angle covered already.
Always on anti-virus on a Mac is always a source of problems, also is MacKeeper, uninstall that here if you have it.
http://applehelpwriter.com/2011/09/21/how-to-uninstall-mackeeper-malware/
If you need to clean the Windows filth off PC files, then use the free, run as you need, ClamXav.

It seems your machine is used in a corporate enviroment, thus likely a rule that anti-virus must be used, you can avoid high CPU usuage by using the ClamXav instead.

Compressed memory showing 0% in activity monitor

On one of my Mac Mini's (late 2012), upgraded to 16GB RAM, I keep getting out of memory messages when running apps and on checking the activity monitor it is showing 0% for all running apps under the compressed memory column. I'm running OS-X 10.10.3.
Any ideas on what's going on here? I've tried resetting the NVRAM....

The system isn't compressing memory because is doesn't yet need to; 16GB is pretty generous. The 'Memory' column includes shared memory (system libraries) so there can be a lot of 'double counting' in the figures. You can control+click on the 'Memory' column headers to get other measures.
Try opening Safari and open a dozen tabs with different complicated pages in each one of them, e.g. some pages news.bbc.co.uk. I'm sure you'll be able to start compression eventually.
Meanwhile, your original issue is a bug, or corrupted file, associated with Solibri Model Viewer. You'll probably need to contact its developer for assistance as I doubt that enough users will be reading this forum for you to get an answer here.

How To Use Activity Monitor

Is there a tutorial or something on using Activity Monitor?
For instance, I'd like to find out what processes are going on to prevent my G4 from shutting down at the scheduled time. (The shutdown deal has been ongoing since first going to OS X.)

Hi, David.
1. What specific version of Mac OS X are you using? Your profile information simply states "10.4". See:• If 10.4.5 or earlier, see "Mac OS X's Shut Down schedule will only work when one user is logged in."
• If 10.4.6 or later, see Mac OS X 10.4.6 or later: Scheduled shut down occurs at Login window even if users are logged in."
2. Note that your Mac must be awake at the appointed time for scheduled shutdown to work. See "Mac OS X 10.3 and later: Computer must be awake for scheduled shutdown to occur."
3. You may want to trash the preferences related to scheduling Startup / Shutdown / Sleep:1. Quit (Command-Q) System Preferences if it is open.
2. There are two preferences files for power management / energy saver settings under Mac OS X 10.4:• If you want to reset the Scheduled Startup and Sleep/Shutdown preferences, trash the file:
com.apple.AutoWake.plist
located in the Macintosh HD > Library > Preferences > SystemConfiguration folder. You may be prompted for your Admin password when you trash this file.
• The Energy Saver preferences related to Computer, Display, and Hard Drive Sleep are saved in the file
com.apple.PowerManagement.plist
which is also located in the Macintosh HD > Library > Preferences > SystemConfiguration folder. As before, you may be prompted for your Admin password when you trash this file.3. Empty the Trash.
4. Launch System Preferences and reset the preferences accordingly.Note that some of the information above is from the "Sleep" and "Shutdown" chapters of my book, Troubleshooting Mac® OS X, Tiger Edition.
Good luck!

Activity monitor won't launch

It pops up for a second in the Dock and then disappears. Is there anyway to reinstall it? or trouble-shoot it? I repaired permissions but it didn't help.

Hi
Create another administrator account - call it whatever you like, test will do. System Preferences > Accounts > click the plus icon. Once you've created this log out of the current account and log into the new account. Now try to see if Activity Monitor will launch. If it does not try a reinstall of the OS but preserve network users and settings. If it does launch then log out of the new admin account, log back in to the old account and move the whole of the Preferences folder in /Users/Home/Library to the Desktop. Restart the mac. On successful log in you will notice that the dock has been reset back to its default - don't worry you have not lost anything. Go to the Preferences folder you previously moved to the desktop and find the com.apple.mail.plist and com.apple.dock.plist and move these two files to the newly created Preferences folder in /Users/Home/Library. If it tells you that com.apple.dock.plist already exists then overwrite it. Restart the mac again and you should now be OK.

Dual 2ghz G5 appears with only one processor in Activity Monitor

Here's something I haven't seen before... a dual 2ghz G5 appears as a single processor machine in Activity Monitor. I ran the hardware test from the CD and everything checked out fine. I then rebooted and zapped PRAM using commandoption+PR... I held the keys down for a while and zapped it three times. System booted up and showed both procs in Activity Monitor. Restarted system again and now shows only a single CPU.
Anyone seen this before?
TIA!
G5 dual 2ghz Mac OS X (10.4.8)

Did you ever use CHUD or Open Firmware to disable a cpu?
My preference with G5s is to boot into Open Firmware and
reset-nvram
set-defaults
reset-all
which should and is easier to rebuild the device tree rather than zap pram (once is enough, older OldWorld systems urban legend was you needed multiple reboots to be sure).

Activity Monitor in Leopard using iDVD

When I create disc image or burn a DVD in iDVD, I use Activity Monitor to watch Disk Activity as well as other parameters. The last time I monitored the starting and ending Reads in, Reads out, Data read, Data written the differences between ending and starting have been negative. Which means to me that at some point each of these registers is reset to zero.
Does anyone know what the reset point or maximum allowable is for each?
TIA

I can't say I like this change but I guess I have to live with it.

You may have installed the "Genieo" or "InstallMac" ad-injection malware. Follow the instructions on this Apple Support page to remove it.
Back up all data before proceeding.
Malware is always changing to get around the defenses against it. In addition to the files listed in the support article, you may also have to remove the following in the same way:
~/Library/LaunchAgents/com.Installer.completer.download.plist
~/Library/LaunchAgents/com.Installer.completer.ltvbit.plist
~/Library/LaunchAgents/com.Installer.completer.update.plist
~/Library/Application Support/IM.Installer/Completer.app
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those.
After removing the malware, remember to reset your home page in all the web browsers affected, if it was changed.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, then you may have one of the other kinds of adware covered by the support article. Follow the rest of the instructions in the article.
If you find Apple's instructions too hard to follow, ask for an alternative that doesn't require you to trust a black-box application without knowing what it does.
Make sure you don't repeat the mistake that led you to install the malware. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
          Install system data files and security updates (OS X 10.10 or later)
or
          Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

Kernal task using 1.03GB RAM in Activity Monitor?

Hello,
I have a 13inch MBP running Mavericks 10.9.4 with a 2.7 GHz i7, 16GB RAM, 500GB HD. I just recently had the machine Factory Reset. The only APP's I've added are PAGES, NUMBERS and KEYNOTE. When I check the ACTIVITY MONITOR it indicates that out of 16GB of RAM MEMORY, 5.51GB is being used. Usually ACTIVITY MONITOR indicates that as much as 9GB RAM is being used. This MBP is 3 years old and I clearly upgraded the RAM from 4GB (I think) to 16GB. Since this MBP used to run with only 4GB of RAM total; it seems to me that the current amount of memory being used, from 5.51GB up to 9GB out of 16GB total RAM is unusually high. In addition, the above numbers were displayed when only Safari and Activity Monitor are running. Is this normal for Mavericks OSX?
Thanks in advance for any help.

I have a 16GB Macbook Pro, and my kernel_task has 1.12GB or RAM, 15.85GB used, split between app memory at 6.67GB, file cache at 7.36GB, and 1.83GB wired.
So what. My Mac is running fine. I do not care how RAM is used, as long as I am getting good performance.
Unused RAM is wasted RAM. My Mac is making sure I get full value from my money.
If you are having an actual performance issue, please describe what you are seeing, what apps you are running at the time, and if you have an anti-malware or Mac cleaner apps running on your system (historical trouble makers).
If your system is running fine, then either do not worry about it, or follow the pointers Linc has provided.

Stupid Rainbow Ball/Activity Monitor

My computer has really been getting hung up a lot lately and it is driving me nuts. I have a 1.33 ghz powerbook g4 with 768 Ram. I am really new to troubleshooting this mac, so I'm not sure what to do. I have performed the disc utilities and mac janitor (which seemed to help slightly). However, it still gets hung up. For example, it just got caught on running word, firefox and activity monitor at once. This doesn't seem like it should be such a big deal!
I don't know if this is relevant, but according to activity monitor, under system memory, there is around 85 mb 'wired', 342 'active' and 278 'inactive', leaving me with 60 free mb (obviously much less if I open one more program). Does the inactive actually affect performance? If so, how do I fix this? Is 768 no longer enough memory to perform basic operations?
Thank you.

This Apple note tells you about each type of memory: http://docs.info.apple.com/article.html?artnum=107918
While in the activity monitor, on the system memory tab, note the page ins/outs. If page outs are 10% or greater of your page ins, you can use more memory for what you run. The numbers reset when you reboot.
I had issues with Safari using a gaggle of memory, so I switched to Firefox, which seems to be more behaved when using system resources.

IMac using 100% of the CPU, but no processes in Activity Monitor show usage over 3%. What's going on?

This iMac is about 5 years old. It has the 2GHz Intel Core 2 Duo processors, 2GB RAM, and is running 10.8.5. After rebooting the machine, CPU usage is low. After about 30 seconds, when using Activity Monitor, CPU usage bumps up to 100% and stays there without budging. When viewing the CPU tab near the botom, % User is about 95+%, and % System makes up the other 5%. They change slightly every second. The problem is, if I sort my Processes by % CPU, the largest user is Activity Monitor with around 2.3%. Everything else is at 0.0%. So there's something weird going on causing the CPU to max out and run hot, but I can't figure out what's causing it. Checking for applications to force quit doesn't show any issues, and repairing permissions doesn't do anything. Is there any way to figure out what's going on? I read about how to reset the System Management Controller, is this something I should do? Thank you for ANY help, it's driving me crazy!
EDIT: I figured it out! Browsing All Processes, I'm running a folding@home program, but I thought I uninstalled it! The process is called FahCore_a4. Is there any way to prevent it from showing up on boot? I want to get rid of it but I deleted the applications!

Be certain to check that you are viewing "All Processes" as opposed to "My Processes"
