[CentOS-virt] how to monitor each VM's traffic?
Hi all Can someone please tell me how to monitor each VM's traffic on a CentOS 5.2 server, running either Xen or OpenVZ? I need to bill my users for the traffic they use, and would like to have a traffic usage graph for each Xen / OpenVZ Virtual Machine on the server. Thanx :) -- Kind Regards Rudi Ahlers ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt
Re: [CentOS-virt] how to monitor each VM's traffic?
Sure, that's for XEN, but it's not very effective. I need graph the traffic for each VM, not the vif - the vifs tend to change on a reboot, and also reset with the stats. How can I graph the traffic over a perioud of time, for any given IP address? Cacti works well, for switches routers, but I can't get Cacti to graph an individual VM on the server.

[CentOS-virt] KVM + bridge + static ip address
Hi folks, I've been reading through the list a bit, and also looked at the KVM How-To on the wiki (http://wiki.centos.org/HowTos/KVM ) but I still have a question. I haven't yet begun to set up KVM, so I haven't made any mistakes yet. :-) My company recently rented a server on which CentOS 5.0 is installed, and my goal is to set up a virtualized instance of CentOS for a new employee to tinker and learn on before I let him have hands on the real server. What I want to do is set up CentOS in KVM, and assign it one of the unused IP addresses on the server so that he and I can access it without having to first connect to the real server. The wiki didn't really give me a good idea of how to accomplish this, and I haven't done a bridge before, so I wanted to check with the list to see if I could get some advice on how to accomplish this. For demonstration purposes, lets say that the external IP address of the real server is 10.0.0.1, and I want the virtualized install to be found at 10.0.0.2. Can someone show me how to modify the kvm rules found on the wiki (and pasted below) to accomplish this? Thanks!

I need graph the traffic for each VM, not the vif - the vifs tend to change on a reboot, and also reset with the stats. set vifnam=xenname in the vif=[] statement and you can give the interfaces symbolic names that don't change every reboot (the snmp mib number still changes, but the snmp name stays the same. you need to setup cacti to map the names to numbers often. ) snmpd in the dom0 will then report for each interface as if the dom0 was a switch, and you can use cacti or mrtg or whatever to aggrigate interface counts. cacti or mrtg or whatever will take care of dealing with reboots resetting the counters. Like any layer2 bridge, you need to be careful of your arp cache... if someone poisions your arp cache, all traffic will go to all DomUs, messing up your counter. But I've had plenty of co-lo providers with that problem on physical switches, so maybe that is acceptable. That said, at prgmr.com, I just run bandwidthd at the head of my network. I hang bandwidthd off of a SPAN port attached to my uplink.The big problem here is that it only supports ipv4. the v6 traffic is free. free! but it works with whatever virt tech you use as long as you trust the to/from IP addresses, and as long as all your traffic is IPv4 ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS] MRTG Problem - no traffic recorded
Hi all,
I've just recently replaced my old firewall with a new one, running
CentOS 5..
Yesterday, I decided to get MRTG up and running again, so I entered
sections like this into the mrtg.conf file:
Title[vlan10]: Bandwidth usage on tenchi.4th-age.com (Internet)
PageTop[vlan10]: H1Traffic stats on VLAN 10 (Internet)/H1
Target[vlan10]: `ifconfig vlan10 |
/usr/bin/awk '/bytes/{ gsub(/:/, ); print $3 \n $8}'`
MaxBytes[vlan10]: 1250
Options[vlan10]: noinfo, growright, bits
WithPeak[vlan10]: wmy
The Target is all on one line in the file.
This config worked fine on my old firewall, but on the new, I get this
in the log files:
[EMAIL PROTECTED] mrtg]# head /var/lib/mrtg/vlan10.log
1218175802 -1 -1
1218175802 3 3 3 3
1218175501 3 3 3 3
1218175500 3 3 3 3
When testing, I ran the mrtg command, precisely as it is written in
/etc/cron.d/mrtg, and that placed real values where now it says -1, but
as soon as the cron job ran, the values became -1 again.
I hope someone can shed some light on this problem..

Morten

I did a lot of installs with virt-install and kickstart. A pleasure. If you don't mind ending up with xvda it's a good way. Depends on your needs.

[CentOS] Re: pam max locked memory issue after updating to 5.2 and rebooting
It has been a few days so I am sending this again incase someone has
seen this issue and might have a seen this problem or has a suggestion
of where to look and why it might not be taking these settings with
5.2 when it did with 5.1

We were previously running 5.1 x86_64 and recently updated to 5.2
using yum. Under 5.1 we were having problems when running jobs using
torque and the solution had been to add the following items to the
files noted
* softmemlock unlimited in /etc/security/limits.conf
sessionrequired pam_limits.so in /etc/pam.d/{rsh,sshd}
This changed the max locked memory setting in ulimit as follows:
Before the change
rsh nodeX ulimit -a
still gives us
max locked memory (kbytes, -l) 32
After the change
rsh nodeX ulimit -a
max locked memory (kbytes, -l) 16505400
The nodes have 16gb of memory.
Now after the 5.2 updates those files are all the same and on most of
the nodes we haven't yet rebooted them due to log running processes
but a few nodes have been restarted and now that jobs are starting to
be put on them we are back to max locked memory of 32k rather than
16gb.
The error we are receiving on those jobs is :
libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes.
This will severely limit memory registrations.

[CentOS] sound
I am using Cent OS 4.6 and a USB speaker (no sound card but USB speaker works fine). Problem is, if I use something like xine or realplay and then later want to visit youtube through firefox, the youtube sound won't work, because even though I exited xine or realplay somehow it still has control of the sound device. Someone in fedora list suggested pulse audio but I can't get that installed. Any suggestions?

I was able to use the wpa_supplicant and its conf file to make this work too, but it was much harder and NetworkManager is great everywhere I go to get connected ... of course YMMV :-D. signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

parted works well for such situations, and if python is your thing,

Sorry, I should have worded my first email better.
I know there are command line tools like fdisk, sfdisk and parted.
I am trying to script the creation of a partition in the free space of a
disk without knowing the exact structure of the disk. Parted seems to
want to know the exact layout you want to create
From the man page
mkpart part-type [fs-type] start end
But the script will not know the start or the end point.
Something similar to what I am trying to achieve is described here
http://ubuntuforums.org/showthread.php?p=5435429
They seem to be creating a single partition the size of the disk without
specifying the exact sizes.
# parted /dev/${i} --script -- mkpart primary 0 -1
Similar to this, I want to create a partition without knowing the exact
start or end point but im not interested in that, I just want to use the
free space.
Hope this is clearer.
Thanks

Hope this is clearer. Having made my living for some months doing this, I offer the general below guidelines. 1. Study sfdisk man page closely. 2. Look especially for the parts where it can output disk and partition information in the form that can be re-read by sfdisk. 3. Use that information in a script (with your preferred combo of bash, perl, (g)awk, bc, dc, ...) to locate total size, amount used, start/end points, etc. 4. Calculate desired changes. 5. Apply to the saved information. 6. Run sfdisk reading the modified output from sfdisk. 7. sfdisk -R (IIRC) to re-read the partition information. Alternately, steps 6/7 could be replaced with gparted if you structure the results properly.

[CentOS] Xen and bonding on Centos 5.2
Hi folks, I am stuck with a weird phenomenon. I have set up two servers as xen servers with bonded interfaces (mode 1). The bond interface works fine on both servers as long as xen is not used. When using xen's network-bridge script (with netdev=bond0), one server works fine without problems, and the other starts upping and downing the slave interfaces of the bond in a very fast manner (several runs per second). Both configurations are identical, the only difference is: - the working server has tg3 nic drivers - the dysfunctional server has e100 nic drivers. Does it really depend on the nic driver if bonding works? And why does it not work in xen, but work fine without xen? What can I do to analyse the problem? I know I could ask this on the xen list, but I fear that this is a redhat/centos specific phenomenon. Any hint or help is appreciated.

I have installed all the necessary snmp tools, yum install snmpd net-snmp net-snmp-utils net-snmp-devel net-snmpt-libs and then started snmpd (/etc/init.d/snmpd start) running snmpwalk, I get the following: snmpwalk -v 1 -c public localhost SNMPv2-MIB::sysDescr.0 = STRING: Linux localhost 2.6.18-92.1.10.el5xen #1 SMP Tue Aug 5 08:11:18 EDT 2008 x86_64 SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (127237) 0:21:12.37 SNMPv2-MIB::sysContact.0 = STRING: Rudi Ahlers [EMAIL PROTECTED] SNMPv2-MIB::sysName.0 = STRING: localhost SNMPv2-MIB::sysLocation.0 = STRING: IS SNMPv2-MIB::sysORLastChange.0 = Timeticks: (6) 0:00:00.06 SNMPv2-MIB::sysORID.1 = OID: SNMPv2-MIB::snmpMIB SNMPv2-MIB::sysORID.2 = OID: TCP-MIB::tcpMIB SNMPv2-MIB::sysORID.3 = OID: IP-MIB::ip SNMPv2-MIB::sysORID.4 = OID: UDP-MIB::udpMIB SNMPv2-MIB::sysORID.5 = OID: SNMP-VIEW-BASED-ACM-MIB::vacmBasicGroup SNMPv2-MIB::sysORID.6 = OID: SNMP-FRAMEWORK-MIB::snmpFrameworkMIBCompliance SNMPv2-MIB::sysORID.7 = OID: SNMP-MPD-MIB::snmpMPDCompliance SNMPv2-MIB::sysORID.8 = OID: SNMP-USER-BASED-SM-MIB::usmMIBCompliance SNMPv2-MIB::sysORDescr.1 = STRING: The MIB module for SNMPv2 entities SNMPv2-MIB::sysORDescr.2 = STRING: The MIB module for managing TCP implementations SNMPv2-MIB::sysORDescr.3 = STRING: The MIB module for managing IP and ICMP implementations SNMPv2-MIB::sysORDescr.4 = STRING: The MIB module for managing UDP implementations SNMPv2-MIB::sysORDescr.5 = STRING: View-based Access Control Model for SNMP.

Re: [CentOS] rebuilding the kernel.
Also, on the procedure mentioned in the link, I am confused about the need to run: rpmbuild -bb --target=`uname -m` kernel-2.6.spec 2 build-err.log | tee build-out.log after menuconfig... I tend to believe that I need to do make all then make modules and make install after reconfiguring the menuconfig. but I did not find that in the wiki link. Could that be a reason? upon attempting to build the new kernel, I get the following: make[1]: *** No rule to make target `init/main.o', needed by `init/built-in.o'. Stop. make: *** [init] Error 2 Is it because I do not have the complete source tree there? How can I verfiry that I have the complete kernel source tree?

[CentOS] Good reference for dkms?
I've just built the nvidia driver for my home machine for the third time and I'd like to put it into a dkms format, but I'm not entirely clear on what goes where to make this work. I googled for a good primer on dkms, but what I'm finding is essentially equivalent to the man page, which, like most Unix/Linux man pages, doesn't really tell you how to do this from scratch. I'm using nvidia's latest driver, r. 173.14.09, which seems to be more recent than the last one I have from rpmforge (1.0.9755, IIRC), although I'm not sure I really need anything other than the rpmforge version. Should I 1) revert to the rpmforge version and re-add it back into the dkms tree? IIRC, this wasn't that hard to do, 'cuz it was meant to be done in the first place. 2) try to bungle my way through with the newest one from nvidia? Or is there a really good primer on dkms that tells what to put where and how to create a proper dkms.conf file (and where)?
