similar to: CentOS 3 vs. CentOS 4 Memory Utilization

Hi, VMWare has been a great tool for me to experiment with CentOS 3 and CentOS 4. However, I'm running into issues with CentOS 5. First, it is *extremely* slow to boot (as in it takes over an hour to boot CentOS 5 on a machine that boots CentOS 3 & 4 in less than one minute). Then, after an hour of slowly watching the messages go by on the console and the CPU of the host machine pegged

I have been trying to install CentOS 4.3 on an HP DL360 G3 (with dual Xeon 3.2 GHz, a Smart Array 5i, and two 36 GB disks doing RAID 1 mirroring). I''m doing all defaults (including the disk and LVM setup) and using the "Minimal" checkbox at the bottom of the Custom machine type package selection screen, so it''s a very "vanilla" install. It zips through the

I have a CentOS 3 box that appears to be having problems where a TCP SYN comes into port 80 for an Apache Tomcat web application, but the rest of the TCP "3-way handshake" isn't happening. When the error occurs, I always see this pattern in tcpdump: * A TCP SYN comes in from the client * ~3.25 second later I get another TCP SYN from the client * ~6.5 seconds after that I get

Does anyone know of a way to track TCP/IP traffic by TCP/UDP port and/or by process/daemon with CentOS? I know a variety of ways to track it in total (e.g., ifInOctets & ifOutOctets with SNMP), but I'm not sure how to be approach seeing traffic by application, port, or process. One option would be to write something that would sift through different stuff for each daemon (for example,

Hi folks, while chasing down a logging-related situation, I happened to notice that when I connect via ssh to my system it makes the following logs: Nov 15 14:15:39 saturn sshd[29868]: Accepted password for dave from ::ffff:10.0.10.14 port 2833 ssh2 Nov 15 09:15:39 saturn sshd[29867]: Accepted password for dave from ::ffff:10.0.10.14 port 2833 ssh2 Nov 15 09:15:39 saturn sshd(pam_unix)[29869]:

A bit off topic, but I keep looking for an answer to this question and coming up with nothing... so I thought I would go to the gurus. :-) Can anyone recommend a good package for pinging other devices and sending an email/alert when they go down? I'm aware of all kinds of more complex things with GUIs and a zillion other bells and whistles we aren't looking for, but we just want a simple

Hi, I am interested in decomposing a time series and getting the trend, seasonal and?irregular variations, as one can get with the "stl" command. My time series is fairly regular, but it has some breaks. From the zoo manual, I gather that it should be possible to convert it to a regular time series and then fill the NA entries by interpolation. I am not able to proceed beyond a certain

Got it. Thanks. I will try it with the trunk version.

Hi there, We''ve been using previous version of bdrb (drb based one) for a while and it was running relatively OK. We recently attempted to upgrade to the new version to keep up / use supported version but we ended up reverting to the older version. Here are the things that moved us to revert : 1) With the workers we never manage to pass this error: '''' You have a nil

Hi, It's become almost routine now to reboot the server every morning. If we are able to log in, after a lag of ~10 seconds, we see the load average is usually > 3.0. As I am writing this, it just went down again. The console had a bunch of text on it, the very bottom reading: <o> Kernel panic : Aiee, Killing Interrupt handler! In interrupt handler - not syncing Here is the

Hello, I have one server with 5 workstations connect on this samba41, the AD is ok, but, sometimes i need to kill smbd process, this process consume 100% of CPU, here is my log from the time of this error: [2014/04/14 08:25:56.200293, 0] ../source3/smbd/posix_acls.c:1815(add_current_ace_to_acl) add_current_ace_to_acl: malformed ACL in file ACL !

What is the best way to make some graphs with bandwidth utilization per IP address? I''m using tc so i was thinking to use the progams from docum.org, is there any other way?

Is there any way to monitor the _real_ CPU utilization for a given xen installation? I have a 4x dual-core AMD system running 10 domU''s, and I''m not sure if I''m overloading or under-utilizing the hardware. I''ve been using xentop to see how much virtual cpu each domU (and dom0) is consuming, but I''m finding it hard to figure out what the _real_

Hi all, If I want to measure the Dom0 CPU utilization, which is a more accurate way among the following 3 options? 1. Running profiling program like "sar" in domain 0. 2. Running Xentop in domain 0 3. Running Xenmon.py in domain 0 By running these 3 different program, the results have certain differences. So I am confused here which to use.Thank you in advance. Lei

Hello, I installed samba 3.01 on my Gentoo Linux box. Recently, I find a strange problem that after I manipulate the shares on the samba server, which is my Linux box, from my Windows XP Pro workstation, the smbd process does not quit even after the file manipulation is done. When I was using Samba 2.2.8, I never saw such problem. Can anybody shed some light? Thanks! -- Peter Wu Powered by

I noticed that if I have single-device allocation for data in a multi-device btrfs filesystem, a balance operation will convert the data to RAID0. This is true even if ''-d single'' is specified explicitly when creating the filesystem. Then it wants to continue using RAID0 for future data allocations, and I run out of space once there''s no longer two drives with space

Hi, I am trying to get the CPU utilization of a node and I am using virNodeGetCPUStats(...) Here is my code snippet. The error checking is omitted for brevity. /* get the number of params */ retval = virNodeGetCPUStats (conn, VIR_NODE_CPU_STATS_ALL_CPUS,\ NULL, &nparams, 0); printf ("nparams: %d\n", nparams); /* allocate space for the params */ params =

Hi, I'm wondering what the proper way is to determine the utilization of host resources when running a couple of VMs. I know xentop but the man-page isn't exactly helpful in explaining what the values it displays actually mean. What I'm looking for is a way to say "Ok, i have 4 VM's running and right now they utilize 40% of the cpu resources the host has, 50% of disk i/o

Hi all, Using XenServer with a RHEL6 beta VM, I have sar installed on the hypervisor and VM. If I do a ''md5sum < /dev/urandom'' to spike CPU usage on the VM, I see the indication on the XenCenter performance graph on CPU 0. It does increase quickly. Neither sar output gives any sort of indication that the CPU is being loaded. This VM is pinned to both processor 0 and 1

Greetings to All, I hope that someone can give me some guidelines with regards to CPU utilization, and at what level CPU utilization begins to effect call quality. Thank you in advance, Joe
