Hi Centos Users The server (ProLiant DL380 G5, Centos 4.3) was not responsible anymore (SSH), fans rotated at full power and the console was blank. After restart it seems to be fine. Now I am analyzing sar statistics (in system logs nothing special, unusual). The hardware monitoring with HP tools didn't work. # sar -P ALL Linux 2.6.9-34.ELsmp (cent061) 01/15/2008 12:00:01 AM

I'm trying to figure out what's causing an average system load of 3+ to 5+ on an Intel quad core. The server has with 2 KVM guests (assigned 1 core and 2 cores) that's lightly loaded (0.1~0.4) each. Both guest/host are running 64bit CentOS 5.6 Originally I suspected maybe it's i/o but on checking, there is very little i/o wait % as well. Plenty of free disk space available on all

We have CENTOS 5.3 on DELL server. I tried to use "sar -b" or "sar -u" and it only show report starting on 12:00 A.M. my questions are: 1. for "sar -u" or "sar -b" how can I generate two or three days ago report? 2. how to generate daily report from "sa2 " peocess? Thanks. ___________________________________________________ ??????? ?

Another question some of you may help me make decisions on. I've been doing some reading that indicates that having HT turned on in this dual xeon machine might actually slow down the computing process rather than speeding it up. I rebooted this a.m., and turned HT off, just prior to my main application run. One thing that might be of note, this application is using OMP for utilizing

Hi everyone, How can i obtain R2 for SAR model? and how can i validate the results, can i use the coefficients directly in a simple formula like y=b0+b1*x1+... or do i have to use the complicated formula for SAR (the one with the weight matrix and rho and...)?   Thanks for any help!  [[alternative HTML version deleted]]

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

Hi all, This is my first post to the list, I hope someone out there can help! I am running xen 3.0.3, with CentOS 5.2 based Dom0 (kernel-xen-2.6.18-92.1.22.el5) Recently I have noticed some complete system lockups on a few different servers. Neither Dom0 or any of the guests respond to pings, connecting a keyboard and monitor to the system only shows a blank screen. Nothing is written to logs

Any help with this problem would be very much appreciated (even "it's not 7.3 or ext3 pointers, look somewhere else"). I've seen a similar post to ext3-users, but since that one received no reply and I'm not convinced it's a ext3 problem (it only appears on our 7.3 hosts) , I'm CCing to the valhalla list. We have the same problem on ALL our Redhat 7.3 machines

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.

Issue: Vista reads slowly from a samba server. This appears to pop up periodically here and elsewhere. My samba.conf file has: [homes] ... vfs objects = readahead As suggested elsewhere. Writes are approximately 17-18MB/s which is acceptable. Reads are in the 8MB/s range which is appalingly slow. Using linux smbclient and windows XP clients I can read at 25+MB/s. I've enabled vfs

All of our Kafka clusters are fairly write-heavy. The cluster in question is our second-heaviest ? we haven?t yet upgraded the heaviest, due to the issues we?ve been experiencing in this one. Here is an iostat example from a host within the same cluster, but without the RAID check running: [root at r2k1 ~] # iostat -xdmc 1 10 Linux 3.10.0-327.13.1.el7.x86_64 (r2k1) 05/27/16 _x86_64_ (32 CPU)

Anyone know how to get statistics on bonded interfaces? I have a system that does not use eth0-3, rather we have bond0, bond1, bond2. The members of each bond are not eth0-3, rather they are eth6, eth7, etc. I didn't see anything in the man page about forcing sar to collect data on specific network interfaces.

I?ve posted this on the forums at https://www.centos.org/forums/viewtopic.php?f=47&t=57926&p=244614#p244614 - posting to the list in the hopes of getting more eyeballs on it. We have a cluster of 23 HP DL380p Gen8 hosts running Kafka. Basic specs: 2x E5-2650 128 GB RAM 12 x 4 TB 7200 RPM SATA drives connected to an HP H220 HBA Dual port 10 GB NIC The drives are configured as one large

Hi, I was checking the source code to the function combn that "generates all combinations of the elements of 'x' taken 'm' at a time.", because I wished to modify it. I have a doubt about a statement. This is the main loop. ._1 <- 1:1 nmmp1 <- n - m + ._1 while (a[1] != nmmp1) { if (e < n - h) { h <- ._1 e <-

List users, Using Asterisk in an inbound call center environment has led us to pushing the limits of vertical scaling. In order to treat each caller fairly and to utilize our agents as efficiently as possible, it is desirable to configure each client as a single queue. As far as I know, Asterisk's queues cannot be distributed across servers, so the size of the largest queue we service

We are struggling with a strange problem. When we have some VMWare clients running (mostly MS windows clients), than the IO-write performance on the host becomes very bad. The guest os's do not do anything, just having them started, sitting at the login prompt, is enough to trigger the problem. The host has plenty of 4G of RAM, and all clients fit easily into the space. The disksystem is a

Ehlo all, I've been working on a migration of about 240K users from one server with qmail, courier imap, maildrop and ldap to postfix, dovecot, lda +sieve. Before the migration the server and the storage were always on high load. Before migration: Storage IOPs = 4600 Read average = ?2800 ?Write average = 1800 Storage CPU (Raid5) Crl0 = 50% Crl1 = 50% Server Load = 120 %user = 35
