Red Hat / Fedora :: Get Memory Usage Info?

Feb 18, 2010

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

Server :: Sending SNMP Traps (Info On CPU / Memory Usage)

Dec 13, 2010

We have a situation where we have to set up a server to send traps with information regarding CPU, memory usage, etc. I know snmpd can be set up to allow another process to request snmp information about the server, but can it be done the other way around (have a host send information about itself to another server through snmp)?

Fedora :: Memory Usage Isn't Adding Up

Sep 17, 2009

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?

Fedora :: Setroubleshootd: High Memory Usage After F13 To F14 Upgrade

May 11, 2011

I upgraded from Fedora 13 to 14 over the network. Everything seems to have worked. The one problem after my install is that I have noticed that setroubleshootd consumes alot of memory.


It doesn't take long for setroubleshootd to jump in memory usage. I can kill the process but it will start up again. I have tried disabling the service but it doesn't show up in /etc/init.d. # service setroubledshootd stop setroubledshootd: unrecognized service So I am not sure what I can do to resolve the issue with setroubleshootd besides killing it off every 15 minutes.

Red Hat / Fedora :: Memory Usage Always High And Utilizing Full?

Jul 14, 2010

In our database, when checking the memory used using top command, we are always seeing 32 GB RAM utilized. We have set the sga_max_size to 8gb and PGA to 3 gb. We have tried shutting down oracle db and then the memory went down to 24GB when checked using top command. After cold reboot of the DB server, it gone down to 1.5 GB.

But once the users are started using after end of day, the memory again gone back to 32 GB.

Top Command output (truncated)
top - 15:18:27 up 5 days, 19:43, 1 user, load average: 0.55, 0.39, 0.32
Tasks: 599 total, 3 running, 596 sleeping, 0 stopped, 0 zombie

Server :: "free" Shows Far More Memory Usage Than Summing Up Application Usage?

Aug 6, 2010

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":


[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092

Red Hat :: Red Hat Box Involving Memory Usage

Jun 2, 2010

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 ?

Ubuntu :: High Memory Usage Under 64 Bit?

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.

Ubuntu :: 10.04: Massive Memory Usage?

Aug 16, 2010

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).

Debian :: High Memory Usage In Cache?

Mar 12, 2011

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%)

Debian :: Memory Usage On A Squeeze System?

Mar 16, 2011

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 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?

OpenSUSE :: Memory Usage 100 Percent - Auto Log Out

Aug 13, 2010

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 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.
