Hi, I had been experiencing a problem on our dedicated server running Centos 5, and unable to successfully track down the problem. Since about 6 days ago, I noticed a spike in load/CPU utilization which went from a typical 0.2x-0.3x to 3.x. At the same time, average traffic also went up and so did the log usage. Prior to this, the server was working fine and there had been no changes to the

Folks I use "yum list installed" to determine if a package has been installed. In particular, I was interested in the "man" program, installed with the command "yum install man". In Centos6, if I look at the results, I see that "man" was installed. This is good. In Centos7, if I look at the results, I see that "man-db" was installed. This

every other day I do full backups to both a second internal disk and an external usb disk. I am using a fully up to date centos 5.1 AMD 64 X2 6400+ machine. with SATA disks. using an NVIDIA chipset, when I do a full rsync the responsiveness of my machine suffers. Slow on the internal disk and really slow on external usb. doing "top" shows 0% idle but only 17% CPU usage by the rsync

We have 1 system ruining Centos7 that is the NFS server. There are 50 external machines that FTP files to this server fairly continuously. We have another system running Centos6 that mounts the partition the files are FTP-ed to using NFS. There is a python script running on the NFS client machine that is reading these files and moving them to a new dir on the same file system (a mv not a cp).

I''m not a windows person, so I am hoping someone can help me with this... I''ve just installed a Windows 2003 Server VM and I would like to make sure that the average disk IO wait is acceptable. In Linux and other *nixes I would normally use sar or iostat for this. I have found perfmon in windows. Will this give me the numbers I need? Thanks, Matt.

Maybe this is a ssh problem - but are you aware of the general issue ? http://bugzilla.mindrot.org/show_bug.cgi?id=182 Summary: ssh should still force SIGCHLD to be SIG_DFL when calling ssh-rand-helper Product: Portable OpenSSH Version: 3.1p1 Platform: ix86 OS/Version: All Status: NEW Severity: normal

We are testing Samba 3 (and 4) on Fedora Core 13, 10Gbit connection with a Mac OS 10.6.4 system as the client. We will be adding some Windows machines sooner or later with 10Gbit interfaces. We are seeing 100-150MBytes/sec read or write performance between the Mac and the FC13 system over 10Gbit interface but it should be capable of 400-500MBytes/sec. We have a local raid on the FC13 system

I'd like to know what the cause of a particular DB server's slowdown might be. We've ruled out IOPs for the disks (~ 20%) and raw CPU load (top shows perhaps 1/2 of cores busy, but the system slows to a crawl. We're suspecting that we're simply running out of memory bandwidth but have no way to confirm this suspicion. Is there a way to test for this? Think: iostat but for

Hello, We are doing digital recording over a 100 Mb/s switched network to a dedicated Samba NAS-Filer and need to optimize our workflow and present some performance data. I just want to be sure, to not overlook some important aspect in my experimental setup. Let me explain in short what is our infrastructure: The Swiss Library for the Blind has started producing Digital Talking Books (see

Hello, When approaching hosting providers for services, the first question many of them asked us was about the amount of IOPS the disk system should support. While we stress-tested our service, we recorded between 4000 and 6000 "merged io operations per second" as seen in "iostat -x" and collectd (varies between the different components of the system, we have a few such

Hello , After upgrading the system from CentOS 7.2.1511 to CenOS 7.3.1611 I see that the average processing time has increased from 5-7% to 12-15% (doubled). Not critical but it is not pleasant. Server as KVM with 5 virtual machines. Someone noticed something similar? If so, how to fix that? Thx.

Hi, I have a server running Centos 5.2 and am implementing a GIS mapserver app. I have some sample logs from another implementation that give me an idea of bandwidth requirements but I would like to check the cpu load. I can not be at the server during the test and am interested in knowing if there is logging of cpu load available. Anyone have experience with this? Recommendations? Dave --

I'm coming from the Fedora arena and I want to build, what I would call, a production server. I'm to the point where I don't want to upgrade every 6-months. I'm running Oracle DB 11g, a Tomcat/JBoss hybrid application server, and several other server type functions. Is there an example of building a server that boots into init3?
