• The list of all the Resource Pools that are part of a group of ESXi

  Hello

  I'm trying to get a piece of code work that will list all the resource pools that are present in a cluster of ESXi.

  • I know I can find what list of resources of a virtual machine resides in.  I don't want that.

  // Find a matching resource pool on an ESXi hosts
    var esxiCluster = esxiHost.parent;
    var esxiClusterResourcePools = esxiCluster.resourcePool_ResourcePool;
  
  
    System.log("what is the ESXi cluster: " + esxiCluster.name);
    System.log("vimtype: " + esxiCluster.vimType);
    System.log("what pools exists: " + esxiClusterResourcePools);
  

  So I know that the vimType will come back with what I expect (ClusterComputeResource).  The question I have is the object "resourcePool" is reference to the root resource list (in my case, it is 'resources').

  What I want is all DRS resource pools are configured.  I need something like "resourcePool_ResourcePool.children".

  Any help is appreciated.

  Thank you

  Hello

  Check if this code example that works in your case:

  var esxiCluster = esxiHost.parent;
  var esxiClusterResourcePools = esxiCluster.resourcePool_ResourcePool;
  var pools = System.getModule("com.vmware.library.vc.resourcePool").getAllChildResourcePool(esxiClusterResourcePools);
  
  // dump names of child pools
  for each (var pool in pools) {
    System.log(pool.name);
  }
  

• How to calculate the cpu in the resource pool

  How to calculate the cpu in the resource pool

  and don't forget that shares in pools of resources are not inherited by the virtual machines in the pools. the action is related to the pool itself.

• 'Custom actions' of the CPU in the Resource Pools: should I also set the VMs child on "custom"?

  Hello world

  Imagine a VMware vSphere 4.1 cluster managed, of course, by vCenter Server, with some 4.1 ESXi hosts.

  This cluster has 3 Pools of resources: development, Production, quality

  Now consider that the Resource Pools have been initially implemented in the following way, about the 'actions' for 'CPU resources':

  -Development: Shared low =

  -Quality: Sharing = Medium

  -Production: Sharing high =

  Several virtual machines were placed in the Resource Pools. Some virtual machines are single vCPU, but others are vSMP ones: some have 2 vCPU and some of them have 4 vCPU.

  Now, I read the following articles of the (large) put at disposal by Duncan Epping, VMware, in his blog "Yellow brick", on "Resource Pools" and actions:

  The Resource Pool priority-Pie Paradox - yellow bricks [written by Craig Risinger]
  http://www.yellow-bricks.com/2010/02/22/the-resource-pool-priority-pie-paradox/

  Actions on Resource Pools

  http://www.yellow-bricks.com/2010/12/14/shares-set-on-resource-pools/

  Actions on a Resource Pool, custom scripted

  http://www.yellow-bricks.com/2010/02/24/custom-shares-on-a-resource-pools-scripted/

  Now, imagine that I have manually changed several Pools of resources from low/normal/high "Custom" and gave them the following values:

  -Development: 3000

  -Quality: 6000

  -Production: 9000

  The virtual machines inside each Resource Pool appear to be all set up to 'Actions' = 'Normal '.

  I want to know is this:

  1 - since I changed Resource Pool shares 'Low' / 'Normal' / 'High' to 'Custom', I should / need to change the 'actions' in each individual VM from "Normal" to "Custom"?

  2 - I'm guessing that the sum of the actions of all virtual machines in a Resource Pool must be equal to the actions that I gave to this Pool of resources. Am I wrong?

  3 - I also guess that the only practical way to make this change to Virtual PCs, if necessary, is to generate scripts, preferably using PowerCLI. Friend, I have right?

  Thanks in advance!

  See you soon,.

  Whatever resources the resource pool level are applicable to this pool of resources and will get the part accordingly. So that resources will be divided between the virtual machines according to the shares they hold.

  Example:-two pool of resources A and B.

  Total cycles CPU = 10000 Cycles CPU

  A part (custom set) = 6000 CPU Cycle.

  Part B (custom set) = Cycle CPU 4000.

  Now a resource pool has three virtual machines powered with shares.so high normal and low on this desire to cycles CPU 6000 cases divided among them in 4:2:1

  VM1 have = 4 * 6000/7 = 3428 cycles cpu.

  VM2 will get = 2 * 6000/7 = 1714 cycles cpu.

  Vm3 will get = 1 * 6000/7 = 857 cycles cpu.

  so according to your requirement, you can change your actions at the level of the virtual machine.

  PS:shares come into picture when there is a conflict.

• CloneVM_Task fails on the resource pool when cloning tempalte

  I'm trying to use the CloneVM_Task to clone a template, but it keeps failing because no resource pool.  We have a cluster with no pool DRS/HA or resources configuration, we use the cluster for the VCA mode.

  I have a reference to the host server, but I don't know what is needed for the pool of resources, given that we have not one.

  While

  cloning a virtual machine from a template, the resource pool is a required parameter.

  It specifies the resource pool that this virtual machine should be attached.

  Incase you do not have a resourcePool hierarchy, you must specify the root

  resourcePool 'Resources' as a resourcePool. It's the resourcePool

  managed your ComputeResource object. A ComputeResource always has a root

  ResourcePool associated with him.

• Summary of the Resource Pool tab

  It is what I read from the book of ICM5:-

  Orders (not shown) component allows you to perform actions such as creating a virtual machine, creating a pool of resources and changing the parameters of a pool of resources.
  I did not understand this line. Can someone help me explain this threshold.

  In the vSphere Client, select a resource pool in the left pane. Now, select the Summary tab for the pool of resource selected in the right pane. There is a component of commands (or box) visible in the bottom left of this tab with the following options: Edit virtual machine settings, new Pool of resources.

• Root user cannot create VMS within the Resource Pool after you rename the Cluster

  Currently, vCenter manages two clusters. I renamed a single cluster and the root user seems now are not allowed to create a new Virtual Machine in resource pools to the title of the group with the changed name. I tried to change the name of the cluster to its original name... no luck.

  The root user can still create a VM under the individual cluster nodes, but not in a resource pool.

  The cluster that has not been renamed yet can be managed completely with the root user. Resource pools it allow me to create a virtual machine.

  I found this last issue and checked on each cluster node that the ACEDataRoleId is-1 for each section: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1031192

  I am at a loss, any help would be greatly appreciated! Thank you!

  I think it's a bug. When I created a new data center and migrate all nodes in cluster about him, the permissions problem I was experiencing did not follow.

  Thank you for your help.

• Good candidates for the resource pools?

  Hi, I do not currently use resource pools, but often the impression that I should watch more in him.  We have our four node 5.1 cluster 16 web servers (among others in the virtual computer) that are exactly the same and serve the same function.  I was wondering if those who would be good candidates to be added to a pool of resources, so they can take resources needed?  I tend to approve statically the RAM and CPU on these "just in case", but maybe it's stupid, if there is a better way.  Thank you.

  Also consider that if you have no compelling reason to prioritize resources for all virtual machines on one of the virtual computer, then you really don't have a reason to use the resource to all pools.  In this case, each virtual computer will be given some memory he needs on demand, DRS will balance the load between the hosts if a host is out of balance, and there will be fairness when ESXi pray return of VMs pages when there is a conflict.

  Discover the vSphere resources management Guide, you will find everything you always wanted to know about the Pools of resources and any other topic of management resources in general.

• Plan a stop of all guests in the Resource Pool

  Hello

  What is the best way to stop all clients in a Pool of resources according to a calendar?

  I want to stop my development/TEST servers at midnight every night.

  With the help of:

  Advances in vSphere 4.1

  vCenter Standard

  Thank you very much

  Welcome to the community.

  Vcenter Server GUI, you can only plan this operation on the specific virtual machines, not for a whole resource pool.

  The best solution is to use any custom CLI... for example:

• Use of the Resource Pool with vSphere Essentials

  A silly question but I have to ask anyway:

  I have a license of vSphere Essentials with my two hosts ESXi4.  I knew that he was not in vSphere DRS.  What was not so obvious to me, it's that you need DRS activated in order to create a pool of resources to the cluster level vSphere without it.  (The option to create a new cluster is grayed out). http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1004098

  So my question is:

  Are there benefits to creating a cluster if you do not have DRS?  I now have to double and create pools of resources at the level of the host for two guests, who is an administrative burden.  In addition, one of the main reasons I have used resource pools was to facilitate the access rights based upon roles to specific virtual machines.   These two will now have to be defined for each host.

  We greatly appreciate your comments on this

  Other than the ability to use the VCA mode and setting up the location of the pagefile.  According to me, there isn't much more to a cluster if you use no HA or DRS.  Since you do not have DRS yor cannot create pools of resources that span multiple hosts within a cluster.

  You will need to create individual pools of resources on each host by taking your host from a cluster and have just in the data center.

• Get the resource pool structure

  Hello

  I try to get the VMS in our resource pools. We have a pool of resources like this structure:

  Tier1 ResourcePool-resgroup-769

  If I get the virtual machines on each resourcepool in the list above, I'd be unable to distinguish if Tier1 is from the branch of a branch of Department2\Prod or Department1\Dev.

  How can I get that information, that is to say, the 'level 1' resourcepool (ResourcePool-resgroup-296) is in which parent resource group.

  Thank you

  There are 2 things to consider before attack us the script.

  (1) resource pools can be created in 2 different locations, under a Cluster and a standalone host

  (2) in the vSphere environment, there are some hidden files. One of them is the pool of resources of the parent 'resources '.

  You can find this file under each group and each stand-alone host.

  The script uses a function called Get-RpPath, which makes it much easier to recursively down the structure of resource pool

  The script now prints the hidden folder "Resources" as the beginning but this can be replaced by the name of the cluster or standalone host just above.

  The script begins with the collection of all of the 'Resources' folders that are hidden in your vSphere environment and recursively then descends from the quest of sub-resourcepools.

  $indent = 4
  
  function Get-RpPath{
       param($rp, $level)
  
       Write-Host ($rp.Name).PadLeft($level + $rp.Name.Length, "-")
       foreach($child in $rp.ChildConfiguration){
            $nrp = Get-View -Id $child.Entity
            if($nrp.GetType().Name -eq "ResourcePool"){
                 Get-RpPath $nrp ($level + $indent)
            }
       }
  }
  
  $clusters = Get-Cluster
  $hosts = Get-VMHost | where {-not ($_.ParentId -like "Cluster*")}
  
  $RProot = $clusters | % {
       Get-Inventory -NoRecursion -Location $_ | where {$_.gettype().Name -eq "ResourcePoolImpl"}
  }
  $RProot += ($hosts | % {
       Get-Inventory -NoRecursion -Location $_ | where {$_.gettype().Name -eq "ResourcePoolImpl"}
  })
  
  $RProot | Get-View | % {
       Get-RpPath $_ 0
  }

  @{N="GB free memory";} E={[math]::Round(($_. MemoryTotalGB - $_. MemoryUsageGB) ,2 )}}

  
  

  
  

  The lines to add are displaying the results of a calculation on performance data, which are obtained through Get-Stat.

  In this script you better start from the script where you have taken these lines and then add the properties of the 1st script.

  In the objects returned by Get-Stat, you have access to the virtual machine through the property of the entity.

• Remove the Resource Pool

• Monitor the IOPS / s in a Resource Pool?

  Hello world

  I am quite new to vROM and just get your feet wet for me.  I've been delving into the book "Mastering Operations Manager vRealize" useful and which was helpful, but I'm trying to understand an important piece on:

  We have pools of different resources for different departments within our Organization, and I try to get a good graph for IOPS / s in each resource pool.  I was able to get a list of all virtual machines in a resource pool by creating a dashboard with the widget resource pool game object selector, then use "Diagnose e/s disk of the Virtual Machine list" view to see all the virtual machines within the list of resources and then for the summary allows you to SUM add them all together.  This gives me a number, but does nothing for this over time.  I'd like to be able to see that number over the next few months (even if it means just go ahead of data today onward, not historical).

  Any ideas?  I think I must be missing something, like the Resource Pool looks like it would be a good way to measure the impact of the drive.  Folder of the Virtual Machine might work also, but is not as clean as I would like.

  Hello world

  Right after I got this resolved so I thought I would mention it here in case anyone else is curious.  It has to do with the SuperMetrics.

  The formula I created is as follows:

  SUM (${adapterkind = VMWARE, resourcekind = VirtualMachine, attribute is virtualDisk | commandsAveraged_average, depth = 1})

  It takes the sum of all virtual machines to a level under the resource pool.  I also used average and Max values, because this helps to show trends and you have aberrant VMs eating a ton of IOPS / s.

  I received lots of help from Iwan Rahabok virtual red point.  Specifically, this thread here: http://virtual-red-dot.info/any-vm-abusing-your-iaas-by-doing-excessive-workload/

• Understand how resource pools really work

  In the research on how to properly nail using the resources for the resource pools in our groups, I found that there are nuances that are not specifically documented about 'Booking' vs 'Limit' that relate to Resource Pools. If someone is an expert Resource Pool please chime. I am specifically looking for validation of what we believe is true.

  Here's the deal:

  So based on my interpretation of the response and our conception of resource pools, it looks like the 'limit' is always an important value that decided the full amount of the memory of the virtual computer (reserved memory + swapped memory shared memory + virtual memory) in a pool of resources to all virtual machines and does not imply that memory is drawn from a pool of resources of the parent.

  In our environment, we allow 'extensible booking '. Our question was, 'the value limit of importance. " We assumed that with the 'extensible' NOT VERIFIED that the value reserve limit didn't matter, even if it is not grayed out. So if the limit is not grayed out, it allows resources to be charged to the parent? I understand that this is not the case. In our case, the limit does not mean that the resources drawn from the parent, but seems rather this sets the cap of the memory of all virtual machines in the pool resource can use (reserved memory, expanded memory, shared memory + virtual memory).

  Example (1): we have a pool of resources called "Exchange-RP' 10 GB reserved, not expandable, and a limit of 20 GB. If we have 11 VMs each configured with 2 GB of ram (individual virtual machines have no reservation but the virtual machine is configured to 2 GB).

  We can power on the first 10 virtual machines (10 x 2 = 20 GB) but the 11 will not because it exceeds the limit.

  In this example how the 10VMs become the 2 GB? I guess everyone gets 1 GB of physical memory and consists of 1 GB of virtual memory (swap, shared, etc., not physical ram). At no time is issued physical memory of the mother.

  Example (2): given the exact scenario above. If the unlimited checkbox is enabled (limit is grey = unlimited), it would mean that the VM 11 would now be allowed to be turned on and booking of physical memory it is just must be shared by all the virtual machines in the pool. It seems that once that we receive too many virtual machines powered that there is too little physical ram per virtual computer and we will begin to see the excessive ballooning and swapping then in turn affect performance.

  Please confirm the above examples is accurate of how memory is managed.

  We are looking to validate that the RP limit value is always important as a strict limit of all memory used by the VMs, not only physical (reserved memory). None of the VMware documents speak to this.

  Thank you

  Welcome to the Forums - example 1: I understand, it's the list resources should act as a host that you oversommit the memory assigned to the list of resources - so you should be able to on this 11th VM - with 11 VM all who are in need of 2 GB and with the limit set at 20 GB - if all VMs using their 2 GB and no page sharing occurring I expect to see ballooning by VM vmkernel swap files - now used if you have 2 GB reservations you would be able to turn on 5 VMs in this example because with 5 virtual machines would use you all 10 GB of memory reserved - value and the vmkernel will not power on a virtual machine if it cannot guarantee its reserve-

  Example 2 - see above - even with alimit together, you will be able to oversommit the memory in the RP - the only thing you will earn if you have the limit set to unlimited is that you be Basel to put multiple virtual machines and impact on all users on the ESx host or cluster -
