Once i login through putty i see one ram usage and when run free -m i see another different one . which one is right? and whats the correct way to get real ram usage?
6569
free -m currently puts out something like this.     I would like to know using grep/awk how we can get the total free amount. i.e. 9083

In the network tab in activity monitor there is a read out of data usage showing sent and received in GB. What this dosnt tell you is over what time period this is, is it from a day, a week and month ?   This is from OSX Yosemite.

Using swap space instead of RAM can drastically slow down a PC.  So why, when I have more than enough RAM available, does my Linux system (Arch) use the swap?  Checkout my conky output below:    Also, could this be the cause of speed and system-responsiveness issues I'm having?  Output of free -m :  $ free -m              total       used       free     shared    buffers     cached Mem:          1257       1004        252          0         51        778 -/+ buffers/cache:        174       1082 Swap:          502        144        357

I thought Mavericks was suppose to utilize RAM memory better, thus run smoother.  Running ML on Mac mini 2012, with 16GB RAM...always running smoothly even with over a dozen apps running.  Now, after installing Mavericks, my Mac is SLOW, eating up RAM like crazy! Looking over usage, of the 16GB of installed memory...on average it uses 10-14 GB RAM when barely running a few apps!!!   There is this kernel_task that is always running with over 1GB of RAM and most apps are not taking that much RAM, so what is using up all my RAM?! File cache? It shows very high in that new description, with about 1/3 of my total RAM

I have 16GB of system RAM. On startup with no applications open except the task-manager Windows is using about 3gb of RAM. I looked in the processes tab, but nothing seems to be out of the ordinary. How can I find out why my Windows is using so much RAM.    all processes from all users      Reading from the poolmon it seems that my wireless broadcom driver is using about 0.4GB of of RAM. Even if I remove  it would still be using  2.6GB on start-up, which is still too much.      After reinstalling the wireless driver associated with the memory leak. I have a new screenshot and would like to confirm that it was indeed a memory leak.

I've been running Ubuntu 17.10 for a good while. Starting yesterday (April 9) the process gnome-software started using large amounts of memory. I don't know if it is related to the update that I took that day.  gnome-software grows to use up to 7G of memory (my system has 8G of RAM.)  This expands into eating up swap and root. My root usually runs at 51% of its total disk space and it went up to 96%. System ground to a halt. Had to power off. Only after some automatic disk cleaning (?) did root return to 51% usage on its own.  This happened twice yesterday and it is starting again today.  After running only 1 hour gnome-software is now using (according to system monitor) virtual mem=5.4G, Resident me=4.7G, memory=4.7G    More info:    This is continuing to happen.  The root disk space is being used in at least the file /var/log/syslog.  Over the last few hours it has grown to 4.9G in size.  I have to manually kill the gnome-software process and delete the log file to keep the computer functional.  When gnome-software starts using memory, the CPU jumps up and down  from 100% to 0%.  This can be seen in the system monitor program in the resources tab. I verified this by stopping the gnome-software process and CPU usage goes to almost nothing.  Telling the process to continue show CPU usage jumping all over again.  This CPU usage doesn't show up in "% CPU" on the process page.  Probably due to the refresh interval?    Even more info:    This is the error that repeats over and over in /var/log/syslog when this is happening. syslog was 1.7G when I caught it this time.  Apr 10 20:27:31 rwkeating-XPS-8300 gnome-software[2485]: g_byte_array_remove_range: assertion 'index_ + length &lt;= array-&gt;len' failed Apr 10 20:27:31 rwkeating-XPS-8300 gnome-software[2485]: Ignoring unexpected response   I verified this by pausing the gnome-software process while doing a tail on syslog and then un-pausing the gnome-software process only to see the error flooding the log.  So it is caught in this loop.  Don't know what it means ... yet.

I was wondering if I could keep program A from reading my entire ram, as it does not need to monitor what program B is doing.  Also I am on windows 8.1 64 bit.

I have just turned on my PC and have two applications running; Thunderbird and Firefox. Whatever else is running is part of Ubuntu's feature set (as well as a few indicators).  This has been ongoing for weeks, so I'm not sure if it's normal behaviour or not.  Right now, my memory usage indicator says that Ubuntu is using 41% of my 6GB of RAM. I haven't even opened Gimp or my other day-to-day things. I'll be buying another 6GB of RAM, this week, so that I don't run out when using Gimp or Openshot, for example.  An overview of my running applications shows that Nautilus is using the most, yet it isn't even open. This seems a little excessive, or am I missing something?

I am using putty to interact with Linux server. I have started a process using putty. The process is running and will take 5-6 hours. I want that process to keep running after I close the putty session. How can I keep that process alive after closing the putty session? I do not want to keep the computer ON all the time. Is there any way to do this?.

The new Task Manager has a great UI in windows 8, however, there are some discrepancies in the data I can not account for:  Machine: 8 GB of total ram. (This is a physical machine, not a virtual)  The processes tab shows 45% of Memory utilized.  The listed process do not add up to 3.5 GB of RAM, but instead add up to 0.948 GB. There is no "processes for all users" option.   The performance Tab Shows:   In use : 3.6 GB Available: 4.4 GB Committed : 4.1 /9.2 GB  Cached: 3.7 GB Paged Pool: 376 MB Non-paged pool: 135 MB  My reading of this says I have ALOT of "cloaked" processes running some where eating my ram.  How do I interpret this data and how do I verify it?

Due to space constraints, I need to purchase a laptop to replace my desktop computer. However I don't know whether I need a laptop with 8GB or 16GB of RAM. My desktop currently has 16GB.  What is the easiest way to run something in the background to determine my typical RAM usage over a period of, say, a month? My goal is to have enough data to base my RAM purchase on real-world usage of my desktop.  I've seen a few articles describing how to use Performance Monitor to do this, but they all seem to suggest different things to monitor. Several of them also talk about measuring my swap, which I don't believe I should be interested in.

Is there way to determine using standard Linux/Unix tools how much a process has spent in User mode and how much waiting for kernel?  In other words, exactly the "user" and "sys" values that you get when using time, but during process runtime?  NOTE: one way is to use WBEM and enumerate Linux_UnixProcess, but I need to use other tool than this; my aim is to verify what WBEM provider tells me, i.e. I need to use different tool.

I have 8GB of memory on a 64 bit windows 8.1 machine, and windows is telling me I'm using 91% of my memory, yet its simultaneously telling me I'm only using 3GB.  I literally just restarted my machine a few minutes ago because it was being incredibly rediculously slow. I'm currently only running chrome (with a ton of tabs, but doesn't add up to anywhere near 7.5GB). What could be going on here?   Here's a bunch of my current info       I took a look at this:  but I wasn's able to use xperf and the rest didn't lead me to a solution.  UPDATE - RamMap:   UPDATE 2: I checked Resource Monitor at Wouter's suggestion and found an "Image" called lxdecoms.exe with over 6GB of Commt (KB). I tried killing the process, but while it lowered my Commit Charge, it didn't affect "Used Physical Memory". So I restarted hoping to capture it again in full, but its not back yet and yet the problem persists.  I should note that I do have a Centos virtual box virtual machine running on my machine, not sure if that has any weird memory impacts that aren't reflected in the numbers in these tools.   I got xperf working, so here's my resource monitor and a wpa analysis of my xperf output (from xperf -on ReferenceSet -BufferSize 1024 -MaxFile 512 -FileMode Circular  &amp;&amp; timeout 5 &amp;&amp; xperf -d MemUsage.etl):     What is N/A that's taking up 2.7GB of memory? My VM?

I am using System Monitor 2.28.0.  When I look in the Resources tab, I see a nice graph with for memory and swap.  Memory is about 60% 2.3 GiB of 3.8.  When I type the command free, I got :               total       used       free     shared    buffers     cached Mem:       3994908    3962396      32512          0     100852    1477032 -/+ buffers/cache:    2384512    1610396 Swap:      8000328      28468    7971860   cat /proc/meminfo | grep MemFree give  MemFree:           34536 kB   The situation has remained the save for several minute.  I started a lot of process with a script and the script is waiting for the free memory to get lower.  According to what I am seeing in the Process tab (or with top), the number in System Monitor seem a lot closed to the total of the memory of the process that the one reported by free.   Thanks

How shall I find out the frequency and type of my current RAM? My OS is Ubuntu 12.04.

I am trying to find out how much memory my application is consuming from within the program itself. The memory usage I am looking for is the number reported in the "Mem Usage" column on the Processes tab of Windows Task Manager.

I would like to monitor one process's memory / cpu usage in real time. Similar to top but targeted at only one process, preferably with a history graph of some sort.
