Hi Ryan, If you want to monitor your oVirt environment (storage domains, data centers, clusters, hosts) using Nagios you can use check_rhev3: https://github.com/ovido/check_rhev3 For monitoring virtual machines with Nagios it's possible to use this plugin as well, but I suggest other (more detailed) methods like nrpe, ssh, snmp or check_mk agent: http://mathias-kettner.de/checkmk.html You can also display all your Nagios check results in oVirt webadmin with the Monitoring UI-plugin: https://github.com/monitoring-ui-plugin/monitoring-ui-plugin Regards, René -----Original message----- From: Shirly Radco <sradco(a)redhat.com> Sent: Sun 10-19-2014 08:32 am Subject: Re: [ovirt-users] oVirt monitoring To: Ryan Nix <ryan.nix(a)gmail.com>; CC: users(a)ovirt.org; > Hi Ryan, > > You can use oVirt reports and dwh packages that collects historical data > and provides reports that enable you to monitor the system currently and over > time. > > http://www.ovirt.org/Ovirt_Reports > > Best regards, > --- > Shirly Radco > BI Software Engineer > Red Hat Israel Ltd. > > > ----- Original Message ----- > > From: "Mooli Tayer" <mtayer(a)redhat.com> > > To: "Ryan Nix" <ryan.nix(a)gmail.com> > > Cc: users(a)ovirt.org > > Sent: Saturday, October 18, 2014 8:27:30 PM > > Subject: Re: [ovirt-users] oVirt monitoring > > > > Hi Ryan, > > > > 1.)

CentOS 7 + oVirt 3.5 + OpenVPN
by Phil Daws 19 Oct '14

Hello: have installed oVirt 3.5 VDSM on a CentOS 7 node and then OpenVPN. The problem I have is that when I start OpenVPN I receive the message: Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip link set dev tun0 up mtu 1500 Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip addr add dev tun0 192.168.124.200/25 broadcast 192.168.124.255 Oct 18 13:29:50 kvm01 openvpn[4159]: /usr/sbin/ip route add 192.168.0.0/16 via 192.168.124.1 Oct 18 13:29:50 kvm01 openvpn[4159]: ERROR: Linux route add command failed: external program exited with error status: 2 and if I run the route command manually: [root@kvm01 sysconfig]# /usr/sbin/ip route add 192.168.0.0/16 via 192.168.124.1 RTNETLINK answers: No such process It would appear the tunnel is up: [root@kvm01 sysconfig]# ip add ls 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: bond0: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN link/ether f2:c9:ce:e5:ac:32 brd ff:ff:ff:ff:ff:ff 3: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovirtmgmt state UP qlen 1000 link/ether c8:1f:66:c4:2c:76 brd ff:ff:ff:ff:ff:ff inet6 fe80::ca1f:66ff:fec4:2c76/64 scope link valid_lft forever preferred_lft forever 4: em2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether c8:1f:66:c4:2c:77 brd ff:ff:ff:ff:ff:ff 6: ;vdsmdummy;: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 46:af:6e:9a:1e:4b brd ff:ff:ff:ff:ff:ff 8: ovirtmgmt: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether c8:1f:66:c4:2c:76 brd ff:ff:ff:ff:ff:ff inet XXX.XXX.XXX.XXX/23 brd 88.150.253.255 scope global ovirtmgmt valid_lft forever preferred_lft forever inet6 fe80::ca1f:66ff:fec4:2c76/64 scope link valid_lft forever preferred_lft forever 10: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 100 link/none inet 192.168.124.200/25 brd 192.168.124.255 scope global tun0 valid_lft forever preferred_lft forever Any thoughts as to why the route will not work ? Rationale for this approach is its a cloud server and wish to use a private network to reach the install VMs on that node. Thanks, Phil

oVirt monitoring
by Ryan Nix 19 Oct '14

19 Oct '14

Hello, I was looking for something to monitor the resources managed by oVirt and not necessarily oVirt itself. It looks like there is a page on Nagios integration, however, I'm getting a 503 when trying to access the site. http://www.ovirt.org/Features/Nagios_Integration Does anyone have any recommendations on monitoring resources managed by oVirt? Thanks, Ryn

iSCSI - recommended LUN size?
by Anthony Alba 19 Oct '14

19 Oct '14

Some noob questions on iSCSI as I am doing an evaluation on NFS vs iSCSI. 1. Is there a best practices guide to LUN sizing for oVirt? E.g. N x 200G, N x 500G, N x 1 TB. http://www.ovirt.org/Quick_Start_Guide#Create_an_iSCSI_Data_Domain "oVirt platform supports iSCSI storage domains spanning multiple pre-defined Logical Unit Numbers (LUNs)." 2. Since we can extend the storage domain, I was thinking of multiples of 200G. Any reason not to do it this way? >From the mailing list: https://www.mail-archive.com/users@ovirt.org/msg13638.html "please note: - you can extend a *storage domain* by adding an extra LUN to it from ovirt-engine." 3. Any production experience with LIO target/targetcli as backend? Thanks! - Anthony

How to fix wrong speed of the Infiniband Interfaces?
by Arman Khalatyan 18 Oct '14

18 Oct '14

Hi, I am using ovirt 3.4.4-1. On the hosts I have 1Gbit(eth),10Gbit(eth) and 40Gbit(QDRInfiniband) interfaces. ib interface is used for the VM migration and iscsi disks. If I go to the network interfaces I can see right speed for eth cards. Unfortunately the IB interface speed is detected as 0b/s. This causes very hi load information on vm migrate face. Which is not true. IB can up to 2GB/s but already on 200MB/s load the hosts interfaces are overloaded. Where can I put the correct speed of IB interface? Thanks, Arman.

18 Oct '14

Hello, I have a question. I'm been playing around with ovirt an I'm loving it. Now I would like to set up a new environment with two or three nodes with a hosted engine, reliable and fast storage and flexible network with clearly separated storage, ovirt-management and multiple VM subnets. I would like to here what you guy' s would buy and set up. Kind regards.

migrating DC
by Fernando Fuentes 17 Oct '14

17 Oct '14

Team, If I move my cluster compatibility version from 3.3 to 3.4 can I migrate my DC compatibility version to 3.4 and cause no disruptions? My VDSM are all up to vdsm-4.14.17 on all of my hosts. Thank you for your help! Regards.
