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 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'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
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?
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?
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)
I used to have a program that displayed system information (cpu/ram usage, stuff like that) but the name escapes me at the moment. The key feature of this program is that it was intergrated into the desktop.
I have a network connection between 3 computers sharing the same net bandwidth with the same router (modem), I wanted to know how much every one of this network taking from the bandwidth, I want an easy program like switch-sniffer (see the pic) to scan the network and tell me how much every one taking from this network in real time.
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
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.
I need to write a script to report useful information on disk utilization for each user's home directory.For each directory I need to show: 1. the long listing of that directory entry (but not the files in the directory), so that I can see the rights and owners of the directory.2. The amount of disk used by that directory, in human-readable format, including subdirectories. I need to have two lines for each user one after the other. For example:
/home/user1 directory info /home/user1 disk usage /home/user2 directory info /home/user2 disk usage
The script will assume that all users, except user root, have their home directories in the /home directory (no need to do anything with the /etc/passwd file). And if the administrator adds or removes users, the script should still work correctly (so the script shows the information for all current users).
Here's what I do know. The command "ls -ld /home/user's_name" will give me the info I need for #1. And the command "du -hs" will give me the info I need for #2. What I don't know is how to grab each individual directory in order to apply the above commands to each of them in order. ???
I'm trying to set up my router, with tomato firmware, to save the bandwidth usage information. One of the 'save history' choices is "CIFS" ... I'm lost as to how to create this save area..anyone able to give me a link to a 'how to' ...or if you've done it, perhaps a step by step?
Im looking for an app pr line of code that could let me observe a process, save the info in a number of variable and then put the gathered info on a file.
Ive been trying with variations of top but no luck. I am running several CentOS virtual servers, VM is 2gb ram 2 processor.
Maybe a script that works over a specified amount of time while writing lines with the info on a text file so at the end i can have a sort of table with the data.
The thing is Im going to stress test the server and I would like to have the data to make some statistics.
I have configured the proxy server. I want to observer users's download information. What should I need to do? Shall I install squint? what is the process? How do I monitor the users?
Is there any way to monitor one process' CPU usage and RAM usage over time on Linux? I am trying to change to a cheaper VPS and need to work out what level of CPU and RAM I need!
I need information about the capabilities and state of the disk...specifically, if it's rewritable (capability) and if it's currently blank (state). Currently, I'm using the output of hal-device to give me that information. The problem is, hald doesn't update the information in response to a burn event... this is a problem, because if a burn a blank disc, hal-device still lists it as blank...and if I blank a disk, hal still lists it as non-blank.
Is there a method to force HAL to update a device, or is there a way to query the disk/drive directly to find out if the disk is blank and rewritable? Or even a method to determine if a disk is blank or not? Additionally, this is for a CD-burning application... so I'm intentionally trying to avoid anything hacky like ejecting the CD and reinserting it... anything of that nature.
I am working on: SUSE Linux Enterprise Server 10 (ia64) VERSION = 10 PATCHLEVEL = 2
Example 1: If Raid is enabled on disk then the information in cat /proc/partitions is shown as : 104 0 35532720 cciss/c0d0 104 1 2104483 cciss/c0d0p1 104 2 33423232 cciss/c0d0p2 104 16 35532720 cciss/c0d1 104 32 35532720 cciss/c0d2
Example2: If normal disk is taken the output is as follows: 8 0 35566480 sda 8 1 102383 sda1 8 2 409600 sda2 8 3 210925 sda3 8 4 2104515 sda4 8 5 32739023 sda5
According to my application I need to find out the information of the disk. How can I get disk information when my system is RAID enabled(cat /proc/partitions shows the entry of the controllers in example 1). Can we get Partitions information of the Disk when Disk are connected to system by controller?
I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.
I need to install Fedora on 4GB SDHC card, so the space is limited.My question is what files (documents, manuals, temporary files, logs, unused packages etc) I can remove, without harming the system?So far I cleaned /tmp, /var/log, trash what else?
I realize bleachbit is supposed to "clean files", but my disk usage is at 11.8%. My disjk usage was at like 6.0%. How in the world did it jump so much? It doesnt appear to be right. The only thing I did not check were the Firefox checkboxes..
