General :: CPU/RAM Usage Log Over A Period Of Time To File On CentOS
Jun 7, 2010
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.
Between the dates 21-June-2007 to 12-December-2010 there are 1270 days. If the total cumulative time a hard drive has been active is 344 days (found this via Disk Utility in Ubuntu 10.10) since it was bought 1270 days ago. What is the average usage hours per day?
I'm using centos 5, kernel 2.6.18-164.11.1.el5I have occasional server network problems (the NIC driver will basically crash/restart causing no connectivity for a period of time) due to the marvell sky2 NIC driver being a problem, as discussed here: This essentially means the server is unreliable when under any kind of reasonable load, to put it mildly.Worse still, the driver problem has not been resolved in 2.6.18.x - but it seems to have been resolved in the latest Linux kernels.I really don't want to compile the kernel from source, etc, but it looks like I may have no choice.Is there a repo which has a pre-compiled 2.6.20+ or 2.6.30+ kernel which I can use,
Now i am writting one bash script. in that my requirement is i need to create one directory and that the directory details to be stored in one file Ex. date/time and all in one file. after that i need to delete the folder automatically exactly after 3months. between these time period in 2month itself i need to send one mail to admin "regarding this still one month only more to delete the folder" . is it possible to do like that date calculation in script.
I installed ubuntu 10.0.4 TLS version and my desktop freezes after a period of inactive time: the screen doesn't change and the apps do not response. It will resume after any key-stroke or mouse action. Is it a feature of 'power-saving' or something else? I need my ubuntu keep 'alive' all the time.
I just reinstalled, and can't get the setting set right so that my display does not shut off after a certain period of time. It is shutting off after a while of inactivity, and I do not want it to.
I currently have fedora 15 installed along side windows 7 on my acer aspire d250. So far it runs great, however I was wondering if there is a way to make fedora 15 hibernate after being in suspend for a period of time, just like windows 7 does. This make sense to me as there is no point in wasting battery life if i can hibernate, but I don't want to hibernate all the time, just suspend for a period of time, like 2 hours, in case I need my netbook again i have quick access to it.
I'm trying to block a site for a certain time.How to Block(deny) perticuler website in certain times of the day , by using squid ? and it seemed promising.I added the lines to my squid.conf
acl office_time time MTWHF 3:00-21:00 acl bad url_regex "/etc/squid/block.acl http_access deny bad !office_time
created a block.acl in the same directory and restarted it.
We are using Red Hat linux 4 .We blocked certain sites through squid for certain ip address.we want to unblock these sites in particular interval ,ie during noon time and after 4.00 pm.
Here we have given
In the sites.txt we have given the names the of those sites that should be blocked
The problem is to unblock sites in sites.txt, for particular intervals
I install Opensuse 11.4 on KDE environment then I changed to XFCE. I don't know how to configure for computer auto shutdown after a period of time don't use it.
I am having some trouble with my opensuse 11.3 internet connection for two weeks. After a certain period connection drops while using both NetworkManager and ifup. For info, I write the outputs of some codes.
I am running Karmic on my laptop, and I have three 1.5 TB external hard drives which I swap between frequently. My problem is that if I leave the drives in, and do not access them for a period of time, they become inaccessible, i.e. I will click on the icon on the desktop or in Places, and it will tell me there is no device mounted, even though I was using it fine just an hour before.
i have a feeling that it is because the USB drives spin down after a period, and Ubuntu detects them as being 'disconnected'. Would it help if I added individual entries for each in fstab?? Or do I need to adjust some settings elsewhere?
EDIT: If this information helps, the HD's are all Seagate Expansion drives, formatted to ext4.
My power went out for an extended period of time and now my graphics are messed up. I started my computer up and I only can get 640x480, so I was trying to reinstall the drivers but the nvidia drivers on the repositroy do not make sense as far as what goes with what, or descriptions of them. I downloaded the driver off nvidias website instaled it. It went to my desktop same problem.
I skipped over Jaunty on my main desktop because Intrepid had been working perfectly for so long. Finally took the plunge to Karmic, and have had major instability problems. I cannot trace them to any particular program I am using. At first it seemed related to power management, since it would lock up every time it had a period of extended inactivity. I have disabled ACPI in my BIOS (I think), and any power management settings I could find in gnome to try to troubleshoot. That seems to have helped, but it still happens semi-regularly, sometimes when I am in the middle of using it. I have tried checking logs and googled anything that seemed important. ie a message in kern.log reads: Clocksource tsc unstable
I'm not sure if this belongs in the Server or Networking section of the forums. Anyway, last month I upgraded my server to Ubuntu 10.04 LTS. Since then, I've had a recurring problem wherein after a certain period of time, the server stops accepting network connections. Ubuntu 10 will continue to reject network connections until someone logs into the server locally, after which time network connectivity is restored and the cycle begins anew. Essentially, the server goes into a "half sleep mode". I say half because the computer is still on and the fans are running.
I've done some searching around various forms and initially figured this issue was related to problems with the Network Manager service (https://bugs.launchpad.net/ubuntu/lu...er/+bug/524454), so I removed the service altogether. However, this problem is still occurring.
I've poured over /var/log/messages and /var/log/syslog, but have noticed no irregular behavior. Has anyone else experienced this issues? I'd rather not resort to downgrading back to Gusty Gibbon if I can help it.
I am happy to provide more information if its needed
No matter what I do, the SWAP usage remains zero all the time. Is there anything I am missing? In the following case (see attached screenshot) I am running make on the kernel that I downloaded. The CPU usage is understandable. But what is the use of Swap when its never used. [URL]. I am on Kubuntu natty. My partitions are as follows:
The CPU frequency scaling monitor won't stay at 800mhz after reboot or a certain period of time. My goal is to always have my dual core CPU locked at 800mhz to have it run cooler. I'm running Ubuntu 10.10 on my toshiba u300 laptop.
I wanted to know how can I set a period of time to a tcp connection to wait for request or respond for tcp block read. which system call or function I can use? Does any body know a very simple quick and easy reference on web for socket programing that has lots of socket programing examples in it?
I'm trying to check my server's bandwidth usage in real time, installed the following programs but none worked so far.
Iptraf - No results even when using iptraf -u Tcptrack - Error : pcap_loop: cooked-mode frame doesn't have room for sll header Iftop - No results, everything 0b
Are there any programs that displays bandwidth usage in real time and actually works on VPSes? Or getting real time bandwidth usage on a VPS is simply impossible?
Screensaver mode was engaged in KDE via Control-Alt-L. Then after a while the screen when blank. I was able to get the login screen by moving my mouse; however, the keyboard was somehow disabled. It would not transmit any input. I hit cancel with the mouse and the keyboard could not bring up the login dialog box. This doesn't happen if the screensaver is engaged briefly - only for an extended period of time (perhaps 30 minutes)
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.
On one of my Samba shares on my server I have a folder of mp3 files of my CDs. The one I am having an issue with is "Clarence Carter/Dr. C.C." (yes, the one with the ULTIMATE party song). The "Dr. C.C." folder name is normal locally on the server, but across Samba it comes out "DMOU3A~H". It's definitely Samba doing it, because I get the same result whether accessing the share from Linux or Windoze. I can still access the folder this way, but it would be nice to not have Samba mangle the folder name this way. I am using Samba 3.4.2 on an Athlon64 X2 system running Slackware64.
this idea to me right now seems stupid and impractical so I'm also looking for solutions outside of this one. I'm creating a set of highly available servers. They currently utilize pacemaker to manage a shared IP address, apache management, mysql management and also drbd handling. They currently replicate, properly failover and run fine. However, this is a shared web hosting setup and everytime a new user is added to the system a username and password is created and the httpd.conf file is updated for their site. I need a way to replicate those changes to the other server. For httpd.conf I'm pretty sure I can just stick it on the apache drbd resource and create a symbolic link. However, for the passwd and shadow files that is not a realistic solution.
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.
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 have a CentOS5 server with a 1tb hard drive.There is only 80gb of data on that huge drive and now I want to make a bare metal recovery backup using AcronisMy question is, how can I estimate the amount of time the backup will take and the size of the image file? Is it based on the size of my drive or is it based on the amount of data on the drive?
