VIPerlToolkit: value ready for a virtual machine

Hello

I do really hard with queries for performance with the VIPerlToolkit. And the examples I've seen too much waste code (but it is difficult to separate important code).

I don't want initialize tons of counters metrics, ids and so on who might be questioned ;-)... I just want to see the values of loans for the last 20 seconds!

Has anyone written a simple script that comes out of the given value of ready for a VM (or VM on the host) and want to share it?

Thanks in advance!

Chris

Please see the attached example, it returns the ready value of processor for a virtual machine.

'Disable the alarm action' for a virtual machine

Hello
I want to disable all actions for a virtual machine alarm, while I have to disable FT to clone a virtual machine. My script are ready for cloning but I have a solution to disable the actions of alarm for a virtual machine via PowerCLI to can´t. Someone knows a solution for PowerCLI 5.1R1?
Thank you

How to find the age of a child and snapshot number snapshot for a virtual machine.

Hi all

How to find the age of a snapshot for a virtual machine child count and snapshot.

This code snippet should help... Assuming that you have the following entries:

VM (VC:VirtualMachine)

snapshot (VC:VirtualMachineSnapshot)

System.log("====== Snapshot details for VM: "+snapshot.config.name+" ======");
var snapshotTrees = vm.snapshot.rootSnapshotList;
System.log("Snapshot Tree Count: "+snapshotTrees.length);
for each (snapshotTree in snapshotTrees){
    showSnapshotInfo(snapshotTree, snapshot);
}

function showSnapshotInfo(snapshotTree, selectedSnapshot){
    if(selectedSnapshot == snapshotTree.snapshot){
        System.log("====================");
        System.log("Name: "+snapshotTree.name);
        System.log("Id: "+snapshotTree.id);
        System.log("Description: "+snapshotTree.description);
        System.log("createTime: "+snapshotTree.createTime);
        System.log("quiesced: "+snapshotTree.quiesced);
        System.log("replaySupported: "+snapshotTree.replaySupported);
        System.log("backupManifest: "+snapshotTree.backupManifest);
        System.log("snapshot id: "+snapshotTree.snapshot.id);
        System.log("state: "+snapshotTree.state.value);
        var childSnapshotList = snapshotTree.childSnapshotList;
        if(childSnapshotList != null){
            System.log("childSnapshotList length: "+snapshotTree.childSnapshotList.length);
        }
        System.log("");
    }
    if(snapshotTree.childSnapshotList != null){
        System.log("Children found: "+snapshotTree.childSnapshotList.length);
        for each (childSnapshotTree in snapshotTree.childSnapshotList){
            showSnapshotInfo(childSnapshotTree, selectedSnapshot);
        }
    }
}

WAIT % - % IDLE, what is the average for a virtual machine?

I did some research on performance of VM problems and worked with the media to see that there is maybe a bottle neck IO that occur with a virtual VMware machine I have performance problems on. The technician found that the WAITING % - % IDLE on average for this virtual machine is around 200%. The tech said it was abnormally high. I forgot to ask her what was normal but wanted to put a post to see if some people out there know what they are on average. What is an average number of see? I have the system done nothing right now and I see 579% waiting and 372% IDLE. The technology has been able to confirm that no IO queue was occurring in the VMkernel or on the HBA controller.
Some average % positions would be useful. Thank you.

Supposibly the amount of time in a State of waiting for I/O is the WAIT - IDLE % difference. I was wondering if anyone had the numbers for this feeling. Is there anyone with some of them?

Q: How will I know the VCPU world waiting for I/O events?

A: WAIT - % IDLE % can give you an estimate on how much time processor is spent waiting for I/O events. It is an estimate only, because the world wait perhaps for other than the i/o resources. Note that we should do it only for the worlds of the WWW, not the other kind of worlds. Because the VMM worlds represent the best guest behavior. For the disk i/o, another alternative is to read the disk latency stats that we explain in the drive section.

WAIT % by itself cannot be used, you must develop and examine the individual vCPU % EXPECTATION values and subtract their idle time. You can't do it on the initial view of a single line by VM CPU in esxtop. If technology that you mentioned did not explain it, he doesn't know what it takes.

I have lots of virtual machines that are never less than 300% when I wait - % idle and I have no problems.

It is an example, I caught NimSoft server:

DHSNMS1 100 100 5 192.63 193,80 0.24 0.03 291,44 1.04

%EST USED (s) 192 - in other words, almost two processors are used 100%

The %Idle is 1.04% WAIT 291.44 - according to the calculation of waiting idle, I have a super serious problems of e/s past But this isn't the case, and expanding, I can see that.

5665 vmware-vmx 100 1 0.09 0.11 100.00 0.00 0.00 0.01

5667 100 vmassistant.566 1 0.62 0.65 99,63 0.00 0.00 0.00

5703 100 mks:DHSNMS1 1 0.01 0.01-100.00 0.00 0.00 0.00

5704 vcpu 100 - 0:DHSNMS1 1 32,35 32.88 67,28 0.28 0.11 67,14

5705 vcpu 100 - 1:DHSNMS1 1 31,58 32.05 68.11 0.00 67.85 0.12

So the changed values unfortunately because of ESXTOP bike when you develop... which is annoying, but anyway. In this you see % waiting is 67 and 68 with another respectively being 3 to 100% (which is normal) and the idle being %, 0, 0, 0, 67 and 67.8. Doing the calculation on the processors shows a wait - slowed virtually 0 - or very little IO wait past with processors. But if you add up all the expectations of % and % is idling, you have 434ish, and the 134ish and do the calculation is the difference of 300 - which is the 3 who are always 100%.

So there is no way we can answer your question, we can only help you to understand how the values should be interpreted.

Waiting for i/o States almost always go on the disc anyway, it is unlikely, therefore, the network or the user entered, looking at the stats of disc ESXTOP is a much better way to determine if there is a problem of e/s.

List of the files in the data store for the virtual machine

Hello

How to list the files of data store for the virtual machine? I can't find reference to the command.

Thank you

If you have installed vCLI and vSphere SDK for Perl, you have extra utilities on top of what is there with the vCLI, take a look at this list: http://www.vmware.com/support/developer/viperltoolkit/viperl40/doc/vsperl_util_index.html

A script that can help with the list of files to store data for a given virtual machine is dsbrowse.pl

SRM 5.5 - vSphere replication - error: impossible to reverse the replication for the Virtual Machine. A snapshot operation cannot be performed

Hi all, we have just run a test DR failover of a couple of virtual machines in our protected our failover site and all site swung perfectly, two virtual machines came online and all applications work well. However when we cam to r-eprotect machines virtual, we get some errors.
One of the virtual machines seems to have lived the reprotect end process, it is still running, but has not moved to 89% for some time. The virtual machine has a couple of grand (a little less than 2 TB) VMDK. slow progress is just a consequence of the large VMDK?
More worrisome is the virtual machine which don't reprotect at all. It generates an error whenever I click on the "Restore" button (error: impossible to reverse the replication for the Virtual Machine.) A snapshot operation can not be performed).

Does anyone have any ideas as to the cause?
Thanks in advance for any help.
Andy

Finally got to the bottom of this. The issue was that reprotect SRM work was trying to dispel any snapshots that were taken on the computer object virtual destination in VMWare, but could not clean snapshots.

The reason why snapshots would not consolidate was because it was snapshots of temporary VEEAM who in fact any snapshot file listed in the VSAN data store. So when we looked through the browser data store, no snapshot file existed in the virtual computers folder. Trying a manual removal also failed.

To fix this, we created a snapshot of the virtual machine in the original data center (note is the engine to the bottom of the virtual machine), this effect was to get rid of the 'fade' snapshot that was visible in the Snapshot Manager that VEEAM backup had left behind. Once this had disappeared, the reprotect back to DCA worked perfectly.

A suspended snapshot could not be created for the virtual machine (DC) ha-data center (DC) \vm\VMware vCenter Server Appliance.

Hello gentlemen,
I can not only save this virtual machine with Backup Exec 2014 for a long time.
They are there was no snapshot in snapshot Manager.
Could you help me?
A suspended snapshot could not be created for the virtual machine (DC) ha-data center (DC) \vm\VMware vCenter Server Appliance.

Hello

I found the solution.

I disabled the JOB BE general relativity.

and the host where the virtual machine belong was not the right time. No Ntp server has been configured.

I did and now there works.

I think that the problem can come from this.

Definition of levels of booking for a virtual machine

The vcloud usage meter says:
NET points = (vGB hours X points per 1 GB reserved RAM) / hours per month

A month calendar of 30 days, a service provider uses the vCloud package provider services - first Edition to configure its virtual machine with 16 vGB for 15 days and 48 vGB 15 days remaining. The level of booking for the virtual machine is set to 75 percent for the whole month.
15 days x 24 hours x 16 vGB x 0.75 = 4 320 hours of vGB
15 days x 24 hours x 24 vGB (vGB 48 x 0.75 but capped at 24 GB) = 8 640 hours of vGB
Total number of hours of vGB = 12 960 hours of vGB
Total points = 12 960 vGB hours ÷ 720 hours / month x 7 points (for Prime Minister) = 126 points
Where "the level of booking' for a virtual machine? Is - this talk on VM bookings each parameter in vCenter Server, or do something to the extent of consumption vCloud himself?

Hello. The reservation level is set for each virtual machine, using a vSphere Client or API.

VCenter shows a network for a virtual machine that is not associated with any host

I have a win2k3 VM who at one point had a network assigned to him called "MONITORING". This network is configured is no longer in the ESXi (5.5) environment. The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct. It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.
In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0. I also see it in the VM - dialog box, change the settings, but there is no option to remove it. Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it. I have checked each host and do not see this listed network object.
I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network. MONITORING legacy network still appears in the config.
For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.
Any suggestions on how I can remove the artifact of MONITORING network?

The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

change default location for new virtual machines programmatically

I know that you can change the default location for new virtual machines through the preferences GUI, but I want to be able to change it for all those who use VMWare Workstation in my company, so that it is more advanced to the personal folder of the user.
Where exactly is stored? I don't see in the registry.
Thank you!

WS does not use the registry to store settings.

Set the path in UNK for each user:

Change tracking (CTK) block is supported for this virtual machine, but was refused. This will increase the CPU proxy and consumption of IOP.

I have problems with a client of VMware image-level in an EMC Avamar backup. So far, we have not been able to find information about this message in the backup log file. It is originally the backup to take a very long period of time (on average 10-11 hours).
2014-02-28 14:20:57 avvcbimage < 14681 > Info: change tracking (CTK) block is supported for this virtual machine, but was refused. This will increase the CPU proxy and consumption of IOP.
We cannot determine why CBT is "denied". Has anyone here run across this issue before or seen any other type of backup VMware image have denied CBT?
Everything I checked watch that CBT is successfully activated since the file vmx for the customer to the Avamar config.
ESXi host is Enterprise Plus 4.1.0 260247

After spending some time on this issue, the ultimate resolution withdrew the Avamar vm and then add it again. After that, CBT began to work properly. It seems that there is a parameter that has been 'stuck' pertaining to this virtual machine that wasn't behaving properly.

Disable the clichés for individual virtual machines?

Hi all
Is it possible to disable support for snapshot for individual virtual machines, perhaps via a parameter for it? Or is the closest answer you to put all its virtual disks in independent mode? Try to see how to better meet the requirements that certain suppliers impose that the VM/device does not catch instant and thought that the best solution is to disable the feature for the specific VM (s) only. Thank you!

You can watch the snapshot.maxSnapshots configuration setting. See KB 1031280 for more information.

List of data store, SpaceProvisioned, Spaceused for multiple virtual machines

Hello
I want to list the data store, the SpaceProvisioned, the Spaceused for several virtual machines.
I wrote the following lines, but this didn t work:
$vms = get - VM v998spwmv10175n
{foreach ($vm to $vms)
$vmname = $vm. Name
$vmdiskprovisioned = $vm. ProvisionedSpaceGB
$vmdiskused = $vm. UsedSpaceGB

Select @{N = "VMname"; E = {$vmname}},
@{N = "VMDiskPath"; E = {$vmdiskpath}},
@{N = "VMDiskProvisioned"; E = {$vmdiskprovisioned}},
@{N = "VMDiskUsed"; E = {$vmdiskused}} | Format-Table
}
What wrong with it? I'm away right?
THX in advance

The following script lists each vDisk in a separate line. The VMDiskProvisioned and VMDiskUsed properties are always those of the virtual machine.
```
$vms = Get-VM v998spwmv10175n

Setting Options such as Hotplug for all virtual machines

Hello!
I have about 5 esxi hosts 5 and about 50 virtual machines
Unfortunately I forgot to select some options like activate the plug-in memory and cpu hot
I have 2 questions
1 can I do this without turning off the machine
2. How do I make a few options like this (or for example another option as vmtools update during the feeding cycle) for all virtual machines in my environment
It's too much time to go to all virtual machines and turn them off and turn on these options
Thank you very much

These features must be enabled before the virtual machine is running. So, you will need to turn them off and then use something like powercli to enable the features and turn them back on.

Here is an example on how to do it with powercli: http://ict-freak.nl/2009/10/05/powercli-enabledisable-the-vm-hot-add-features/
