Hi, I'm trying to migrate a user from Outlook.com IMAP to Dovecot. I'm using a setup similar to that on http://wiki2.dovecot.org/Migration/Dsync: imapc_host = imap-mail.outlook.com imapc_user = [...]@hotmail.com imapc_password = [...] imapc_features = rfc822.size fetch-headers mail_prefetch_count = 20 imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = yes ssl_client_ca_dir =

Hi folks, is it possible to monitor and gather statistics in realtime (CPU, memory, HDD, network, ... - something like dstat) of guest systems with libvirt through console from host system (KVM based)? If yes, do those guests need to be created through libvirt? Thanks for your help and time.

Hi, I am trying to boot a server via PXE with following configured for its PXE. LABEL IMP MENU LABEL IMP LINUX memdisk INITRD linuxIso.iso APPEND iso I haven't been able to get this work, probably only because of network speed. PXE server is on RHEL 5.8 and syslinux 5.x While I was booting the server, I ran dstat on PXE server and saw the outgoing network speed was 400-500Bytes. So looks

I am using Xen 3.1.0 in centos 5.4 I have one VM consuming 100% cpu  and all other VM (linux) become very slow (no ssh and vnc access). I could access host via ssh but not VM. host cpu is about 95% idle using dstat. Pls advise how to avoid this. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi List, Is there an easy way to get a count of the number of active socket connections, or even better, number of socket connections in the time_wait state? (Something lightweight... under /proc/sys/net/ipv4/? I'd like to avoid the impact of listing out all the connections a-la netstat.) Thanks! -Jeff

Hi, I am attempting to write a monitor to gather Samba Server performance metrics. I would like to get raw metrics directly from the server itself rather than a 3rd party tool. Could anyone point me to docs or enlighten me on how to accomplish this? I am looking to determine the availability of the server (up or down), the number of files requested, any caching information available

Hi Everyone, My Xen host has 2 X 1TB hard drives in a RAID1 setup. If one DomU starts to dd a 5GB file (A ran it in a loop as a test), access ssh on the other DomU becomes very slow. Is this normal? Many Thanks _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Everyone, I''m experimenting with ionice, and I have to say at first impressions I''m very impressed! Does anyone have any idea how I could script the ionice config? I''m using phy for my DomUs so everything appears in ps as blkback.<DOMID>.xvda1 The problem is, is that the process id for the blkback process will change after every DomU restart,

My Centos 5 server has seen the average load jumped through the roof recently despite having no major additional clients placed on it. Previously, I was looking at an average of less than 0.6 load, I had a monitoring script that sends an email warning me if the current load stayed above 0.6 for more than 2 minutes. This script used to trigger perhaps once an hour during peak periods. Even so, I

Reading the "waiting IOs" thread made me remember I have a similar problem that has been here for months, and I have no sulution yet. A single CentOS 5.2 x86_64 machine here is overloading our NetApp filer with excessive NFS getattr, lookup and access operations. The weird thing is that the number of these operations increases over time. I have an mrtg graph (which I didn't

I have a USB disk connected to a Poweredge server. The USB Disk is a Mad Dog MegaVault with a 160GB drive installed. It's all working fine, but the external LED on the unit is not working. I'm currently running a script (yum-pull) for setting up a yum mirror and it sits for long periods of time seemingly doing nothing. I started the script this morning at 6:20 for my FC4 yum mirror and

How do I check if the proper sata drivers are being loaded? If they are not what can I do other then rebuilding the kernel? Thank you in advance, Randy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Everyone, I'm at the last straw. For at least 5 to 6 months I have tried to get Samba 2.0.6 and Samba 2.0.7 to interoperate with Windows 98, with only partial success. Whenever a Windows machine does an SMB query of the master browser on my network, it takes an abysmally long time to respond. Whenever a Windows machine attempts to print, it becomes unstable and starts crashing. I'm

I have trouble documenting an R package. In my .Rd file (sixth line below), I have uhat<-m%*%y but when the package is built (successfully), the matrix multiplication part does not show up in the documentation.

Hi, I'm running a CentOS 4. server and I sometimes face a weird problem. It is a weird performance problem, and here is how I discovered it. This server runs OpenVZ virtual machines, and one of them is an asterisk server for my personal use. The first symptom of the problem is that the voice quality became flaky. So I logged on the server to see what could be eating cpu cycles, when I

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.

Hi, We have a storage server (HP DL360G5 + MSA20 (12 disks in RAID 6) on a SmartArray6400). 10 directories are exported through nfs to 10 clients (rsize=32768,wsize=32768,soft,intr,nosuid,proto=udp,vers=3). The server is apparently not doing much but... we have very high waiting IOs. dstat show very little activity, but high 'wai'... # dstat ----total-cpu-usage---- -dsk/total-
