Software :: Tracking Memory And CPU Usage Of Software
Apr 19, 2011
How can I keep a record of the memory usage of a particular software?The software I have in mind is firefox. All I want to do is to record the memory and cpu usage in regular intervals of time.htop (top) revels that firefox runs with many PIDs. So, is there a single command to keep track of the complete PIDs of firefox. If there exists a command to check the total usage at an instant I can write a script to run it periodically..
I've been reading an interesting article about the fact that ISPs are able to collect net data from web users. What I think It's missing in the article is that in some locations it's compulsory for ISPs to collect and save all your networking data (For example, in Spain, where I live, it's compusory to store people's activity on the net for a period of 6 months (minimum) to 2 years (maximum). In the article they state that Witopia can do the job of encrypting your browsing activity and therefore mantain your privacy. Do you know any open source or, at least, free alternative to Witopia? What do you think about the article and about the ways of safeguarding your privacy?
I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.
I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.
I am looking for free database that has low memory usage and innodb and memory like engins that has C API and support trigger and client/server support for using in embedded linux systems.
I am sure that all of us know the result of top command in linux. i want to get the value that the top command return as CPU usage, memory usage. so how do i do(programming relation)?
I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
I had been running "Etch" and upgraded to "Lenny". Now my mouse is NOT tracking correctly. When I move the mouse and then press and release the 'ctrl' key to show where the mouse pointer is the circle indicators are not where the pointer is. I therefore cannot make any selections from menus as 'lenny' thinks the mouse is somewhere other than where the pointer is. Also are there keyboard hot keys that i can use to access the menus?
Is this normal? I check system monitor and the top most is xorg followed by compiz. When I first started with 10.04 few days ago it was around 300-500MB.
I am having a few problems with a red hat box involving memory usage. I have 64Gb memory and 'top' tells me I'm using 60Gb of it, but if I add up all the '%MEM' figures I get no more than 20%. Where is the other 80% ?
We have an ORACLE instance that is using shared memory but this is ceilinged at 45Gb. That means there is about 15Gb unnaccounted for . What utilities can I use on red hat to ascertain memory usage other than 'top' ? Any better ones, more detailed, looking at shared memory etc and swap ?
I'm trying to understand the performance of my machine and memory usage just isn't adding up. When I run top it will typically show 301M of 308M used but the total of everything in the RES column is no where near 300M and the total of %MEM column isn't more than 20-30%. So how do I figure out what is using all the memory? Then is there some way to control it to optimize performance?
I am a bit worried about my linux vserver box. No more memory is left. To investigate this issue, i was looking at "top". But it deeply confuses me. It seems that no more memory is left, altough the process list in top never adds up to 100%
My problem seems to be very simple, it's high memory usage. I occasionally will use movie player to watch a few shows and I use firefox as well. My memory usage starts out real small about 500 mb but after using firefox lightly and movie player it jumps to almost 2 gigs and this is after they've been closed what gives? I've attached an image so you can see what I'm talking about.
I've been having some problems with Lucid; all my applications seem to be hogging memory like no tomorrow. Within about 15 minutes from booting the system, processes like Google Chrome, Nautilus, Python, Pidgin all start to take seemingly too large amounts of memory.
Chrome is the worst one, easily shooting over 200-300MB of my 2GB's of RAM. I would have reported this as a bug in Chrome itself, but my other applications seem to share the problem to some extent. Also: My colleague has identical hardware and identical versions of Ubuntu / Chrome, while he has no memory problems whatsoever.Currently I am running Chrome, Geany, Pidgin, Thunderbird and FileZilla. For this and itself, Ubuntu now consumes 1.8GB of RAM (that's including 500MB cached).
Memory of my Linux database servce is all used up. I first noted that this morning and rebooted the box. 5 hours later, it saw used up again. I want to find out which process is responsible for using most of the memories. What Redhat Linux utility can list processes sorting by their memory usage, like the Windows task manager?free and vmstat - summary but not for each processtop appears to be infomative, but sum of non-zero %MEM never add upp to 100
I've installed my debian sid about one month ago (first xfce, next gnome) but noticed that it's kind of really slow. The upgrades take ages, launching (and using) firefox takes so much time,... In comparaison to my ubuntu, archlinux (on the same computer) or previous installation of debian there is clearly a problem somewhere.Today I tried to do a "top" sorted by mem usage : 3.5% xulrunner-stub, 2.1% dropbox, 1.4% aptitude (doing upgrade), 1.4% clementine,... nothing terriblebut still I've 2.7Gb or RAM used (more than 50%)

I use a Debian Squeeze system running off a flash drive, i.e. based on a custom Live image running in persistent mode. It runs great and I am grateful for the existence of Debian . However, I have a question. A lot of the machines I use this pen drive on are quite old, often with 512 MB RAM and old processors. I specifically built my system using XFCE and lightweight apps off an initial live image using the standard-x11 package list (basically just Xorg with drivers and the base system). At first things ran very well, blazing fast even on the oldest systems and could comfortably run Firefox along with LibreOffice side by side (I need LO as all of my colleagues use Word docs, often with track changes, which Abiword can't handle properly). However, over time, I've found that memory usage has risen, tot he point where Firefox is now automatically killed on the older systems every time I start LibreOffice.how does one figure out why memory usage is going up? I've checked for inessential services and turned them off with "insserv -r". I've used only lightweight apps, as mentioned before. Are there other general tips on reducing memory usage?
My memory usage keeps building up and up as time goes by, when it hits 100% it logs me out. I have a tad over 9 Gib in swap, that is how it was set up when I did auto install and let it do the partitions. I have 4Gib memory. When I first log in it shows about about 800+ MB being used and starts adding more from there. I can run applications for about 6-8 hours before it hits the 100% marker. At first I was blaming this on the video player, but when I put on a play list each song seems like it gets stuck in memory also adding about .02% per song to max memory.
This seems to pertain to each application I do. Uploaded with ImageShack.us. This pic shows my Computer setting and usage through system monitor and conky script. In another note, I never see my Swap partition being used at all. I am real green to linux and not sure if I was suppose to turn something on. In the partitioner it shows it being mounted and as swap.
In linux, how can I display memory usage of each process if i do a 'ps -ef'?I would like to the 'virtual memory', 'res memory', 'shared memory' of each progress. I can get that via 'top', but I want the same info in 'ps -ef ' so that I can pipe the output to 'grep {my process name}'.
I like a lot of the last Ubuntu editions, but my computer is a little old, and Ubuntu becomes slower each edition to me.
I get a AMD Athlon 2 GHz, with just 512 MB of RAM memory...
I tried to customize my last installation of 9.10, but i just mess up with the OS. Well, I googled for informations about reducing memory usage, as well others speed-ups but all them are a bit older. Does anyone know any resource about this?
Until now I just disabled startups programs, but i really want is remove packages and everything that I don't use.
One thing thats get me up set sometimes is that I run Win XP pro under a cryptographed partition, and even yet its very fast in my PC. I even tried Windows 7, and its was faster than the Ubuntus I installed.
When I'm using the 10.04, there is a lot of memory used by cache, specially Gnome...
