General :: Checking The Disk Usage Of Different Servers Using Df -h Command?
Jan 7, 2010
how to Check the disk usage of different linux servers using df -h linux command. My host server is 66.50.100.1, I can check its disk usage by using df -h command. I got my disk usage. Now using my host server Im going to check the server 66.50.100.3 disk usage. Is its possible to check the disk usage of 66.50.100.3 using my host server?
Is there a command to check specific processes that's using the most IO/disk usage? I know sar and ps but I want more specific details on IO on individual processes
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.
The command time shows the time taken by a command to complete. Is there a command that shows the change in disk usage caused by a command? I would like to know how large a package is when I install it from source.
I regularly use 'df -h' to check usage on each of my primary directories and mount points.
I'm currently somewhat confused by disk usage within my filesystem, so I'd like to do the following:
Display directory size of all, or say, the 10 largest, subdirectories to a specified directory. So, if I passed the root (/) directory, output would list the subdirectory of / with the largest disk usage first and its associated disk usage listed in human readable format (either M or G suffix as appropriate), followed by the subdirectory and usage for the second largest directory and so on.
Can anyone suggest a command or series of commands to do this?
I am running latest apache2 available in the lucid repos on my desktop. All packages are updated as of this moment. Now in the root of my web server I have placed several soft links that point to folders on another ext3/ntfs partitions on the same disk. When I try to download any large file (say above 500M)on this server using firefox, when the 'save' window appears, my desktop freezes, I notice very high cpu-ram-disk usage, even though I have not yet clicked on 'ok' to save the file. This issue is not present when the file size is small. Note that firefox and the webserver are running on the same computer.
Also I have tried nginx and lighttpd and the issue is present there as well. When I tried downloading the same files using Internet Explorer 6.0 using a XP VM the issue is not present. However on Windows as well using Firefox the issue recurs.
I've just installed ubuntu 10.04 and the message text that shows when you ssh in shows the disk usage of /home.How do I get it to show the disk usage of the entire root / instead? (like it used to on some older version of ubuntu)
Sometimes at startup I get this message "Checking disk 1 of 1". Does that mean it's checking all partitions on the hd? After a bad shutdown there is no prompt for fsck to run and the system just boots up. In fstab I have both options set to "1" for the partition Ubuntu is on, all others set to "0". Any ideas on both?
I am running Ubuntu 8.04LTS x64 on a Dell Poweredge 1900 with a Perc 5i RAID Controller. There are 3 500Gb SAS drives in a RAID 5 configuration. The Kernel is Linux dtpfs 2.6.24-27-server #1 SMP Wed Jan 27 23:39:33 UTC 2010 x86_64 GNU/Linux Approximately once every 1 - 2 months I have a problem where the disk usage starts to rise for no apparent reason. When I run df the usage grows steadily over 2-3 days from 26% to 100%. At this point Samba reports that the disks are full. Baobab does not report the additional usage and the tape backup ignores the 'extra' usage and just backs up what was previously there. When I reboot the machine the usage is set back to normal and we can continue.
I'm monitoring all kind of things like ( Mem, network, cpu, IOPS,..) But still not found a command where i can see the CPU usage but in MHZ ( or Hz). Using top or looking into /proc/cpuinfo doesn't give me the info i want.
I'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code: [root@Zion ~]# df -h Filesystem Size Used Avail Use% Mounted on
I am just wondering if there are any tools for checking the life of the hard disk. I had my hard disk for 4 years. And now I think it is having some problems.Is there any tools I can use to check the condition of the hard disk?
We are running IPmonitor to monitor the disk usage on our Linux servers. It does not seem to coincide with what is reported when running df -h. For example on a Red Hat 5.3 server - our IPmonitor shows that 85% is used on the /usr partition, however when I do a df -h on the server it shows that 91% is used. Why there would be a discrepancy? IPmonitor uses SNMP.
I am trying to get my head around my new server. I am using CENTOS 5.4 x86_64 with 300GB harddrive.
The 300 GB been partitioned with the following:
Device Size Used Available Percent Used Mount Point /dev/md0 99M 18M 77M 19% /boot /dev/md1 16G 8.7G 5.8G 61% / /dev/md2 246G 40G 194G 18% /home /dev/md3 4.8G 1.6G 3.0G 35% /var /usr/tmpDSK 3.9G 432M 3.3G 12% /tmp
I have increased teh tmpDSK as it was getting full very quickly. My question is, what are these md0; md1, md2 and md3 are they harddrive partitions and as md1 is getting full will that have an impact on my sites.
I am looking for a command line utility like ping that can use for checking appropriate services on a server . I do not want do any port scan . I just want to use it for checking apache , mail,ftp and other services on a server if they are running or down.
How do I get Ubuntu's "Disk Usage Analyzer" to show me the hidden files?
It tells me my home dir uses 3GB, but only accounts for 525MB (the results of du -shc *). Can I get it to show me the other files that are using the space?
I've been trying to identify all files on my cut-down version of Damn Small which contain the text string "User Agent:" in them. Because it's only 120Mb in its entirety, I'm quite happy to have grep search the whole system. I'm using this command, but it just generates errors as you can see:
Trying to understand grep,sed,awk but maybe its too early for me and also i suspect iostat is not the correct program for exactly what i'm looking for...The goal is to print only the current read and write speeds of the disk, represented in a numerical value with two separated commands. So for example when writing a file to disk from an external disk, the value reflects the speed of the process.
"iostat -dk sda" prints Code: Linux 2.6.38 (Infidel) 07/30/2011 _x86_64_ (4 CPU)
Some thing is using up a huge amount of my disk space about 10G and I can not determine what it is. When I look at my disk usage in system monitor it say I have used about 25G and when I scan the directory in disk usage analyzer the entire file system used is 15G.
My problem is extremely slow write on hard disk and 100% cpu usage and it happens when I want to write something on the hard derive not any other external derive.
Tried a fresh ubuntu install. No change. I am not even sure if it is a software or hardware problem.
Im trying to list the cpu usage of all process that have a cpu usage of 10% or more. Im not interested in the lower usages. Im using the top command and can get a list of all the cpu usage for all the process but cant only get the processes with 10% or more. I'd want these processes sent to a new file. Would I be able to cat the cpu usages and PID into a file?
