• How to call dll com APIs that range from the performance counters of less than 1 ms with CVI and always get less timer resolution of 1 ms

  Hello

  I've created a dll com in VC ++ using performance counters/timers to less than a millisecond.

  This is useful when you send a message to very high speed. (say 10 or more)

  This is done by the dll.

  When I use CVI to create a user interface, this dll runs at a fixed rate of 1ms.

  This slows down the application.

  I tried to use the same dll with VC ++ host and it works well.

  I need to check the registry setting to see if the useDefaultTimer is set to false or TRUE.

  (I'm not near the development PC) However, by default, it should be FALSE and I have no fidle with it.

  Veuileez post any suggestions you might have.

  Thank you!

  This problem is now solved for me.

  Just the highest thread priority in the dll.

  Thank you if you had the answer.

• How to calculate the IOPS datastore / s and latency via Powercli?

  Hi all!

  I want to calculate the IOPS / s (RO/RW) and the latency of the data via Powercli store, but I cant' find this metric in Vcenter (in the data store tab) and see no metric for data via the cmdlet Get-Stat store.

  How can we measure IOPS / s and latency of data store?  For example I know veeam monitor this information - http://cdn.swcdn.net/creative/v16.8/images/screenshots/products/VM/Lg/EN/VMan60-Orion-Datastore-Top_Lg_960x540.jpg

  I know, I can get this VM or vmhost metric, but I need information on the data store.

  How to measure for IOPS / s and latency of data properly store?

  Thanks in advance!

  These measures are collected on ESXi nodes, entity would need to have the ESXi nodes where these data warehouses are connected.

  You can use the Instance property to filter.

  Under the PerformanceManager , you see all the measures for each indicator it indicates under which entity this metric is collected.

  

  And Yes, the cmdlet Get-inventory returns no data warehouses.

  There is a little, aggregated metric for data warehouses, I'll have to find an alternative for those.

  Nice catch!

• How to calculate the CPU Ready on Cluster DRS via Powercli?

  Hi all!

  I have a DRS Vsphere cluster. I want to know what is the value of the loan of CPU I have in my group.

  For example, I get 20% of powercli value, it is normal for the cluster, but if I have 100% or more, I have a problem.

  How to achieve via Powercli? And how to calculate the percentage values correctly?

  I know, I can get all values of CPU Ready of VMs cluster, but IT is not the same thing, I need overall value of CPU Ready.

  Thanks in advance!

  As far as I know you can get the cpu.ready.summation for ESXi nodes or VMs.

  For a cluster, you will need to get the value of each node in the cluster ESXi and then take the average.

  The metric cpu.radey.summation is expressed in milliseconds.

  To get a percentage, you need to calculate the percentage of loan period during the interval during which it was measured.

  Something like this (this will give the loan current %)

  $clusterName = "mycluster.

  $stat = "cpu.ready.summation".

  $esx = get-Cluster-name $clusterName | Get-VMHost

  $stats = get-Stat-entity $esx - Stat $stat - Realtime - MaxSamples 1 - forum «»

  $readyAvg = $stats | Measure-object-property - average value. Select - ExpandProperty average

  $readyPerc = $readyAvg / ($stats [0].) IntervalSecs * 1000)

  Write-Output "Cluster $($clusterName) - CPU % loan $(' {0:p}'-f $readyPerc).

• Export data of material state via PowerCLI

  Hello

  I was just wondering if anyone have used PowerCLI for export the xml information of material status for a host to vCenter?

  I'm not really familiar with PowerShell and PowerCLI so I don't know if this is even possible but it would help us to completely automate some pilot third party verification.

  Thank you for your time and help

  Matt

  You can check the driver versions when you are connected to a host without the need for an XML export.

  I've attached a quick script and dirty to write versions of all the drivers in the console.

  Main points of the script:

  Connect-VIServer - Connect to vCenter

  Get-VMHost - lists associated Hosts the vCenter

  Get-EsxCli - access to the host ESX CLI

  $EsxCli.system.module.get("$DRIVER_NAME") - retrieves the VMKernel module (if the system knows about it) by name

  It's just the best way to show how to get information about the drivers. Basically you just connect the vCenter Server via PowerCLI, then connect to hosts one by one. When you are connected to a host, use EsxCli to obtain the driver information (module).

  I also forgot to add a line at the end of the script, so here it is: ' $DISCONNECT = Disconnect-VIServer $VCENTER_SERVER-force - confirm: $FALSE.

• Collect information of the NIC via PowerCLI

  Hi all

  We need to collect the following information about all the cards in all hosts via PowerCLI:

  -name

  -manufacturer

  -version of the driver

  -firmware version

  -MAC address

  We know the esxcli method, but it would take a lot of time that we have many hosts and they would send an alarm to deactivate the lock mode and activating SSH and it would be extremely long and inefficient.

  While Google search, we found this method through Get-EsxCLI (http://jreypo.wordpress.com/tag/powercli/), but for some reason that I can not even list the NICs.

• Help, I changed the password of root ESXi via powerCli, now I can not connect with the web client or the console.

  Help, I've changed the root ESXi via powerCli password, now I can not connect with the web client or the console, but I can still connect to powerCli. The command I used was;

  SE connect-VIServer esxihostname-user root - password newpasswd

  This production network btw, I have connected to each host and run the above command, these ESXi hosts are not on a domain

  y at - it something I have left out. I really appreciate any assistance that you people can provide.

  Thank you, Joe

  It is probably a longshot, but a lot of things in the land of windows is not sensitive to capital letters as Unix is.  I wonder if your new password you put through powerCLI mixed uppercase in it and if the capitalization was abandoned by command windows powerCLI Analyzer, or he interpreted as all capitals or something.   If you can still get through the powerCLI you could try to reset the password again to something simple without capitalization mixed case and if your password on ESXi strategy requires a special character, try something different than a "$", like a "_" (I find that a '_' is less likely than some other special characters (, as a '-' or a ' / ' to cause problems with analyzers.).

  Edit:

  Another thing, you can try before playing with the password once again, is to create a different username ESXi using powerCLI and see if the password ends up what you think, it should be, and if you can get with the client vsphere using it.  In this way, you can find out if there are some problems with certain characters or Cap through command powerCLI Analyzer without losing your remaining root by powerCLI access.  After some tests, you can understand what went wrong with your initial password change and may be able to fix it with less risk of losing access.  I also assume that you can not create a new username on ESXi who is able to change the root password no matter what authority give you it, otherwise, you could create a new username with PowerCLI, then connect to the client vsphere with it and change the password to root from there.

• Cultivate a disc of virtual machines via PowerCLI

  Hello

  I'm looking to cultivate a few volumes on some servers via PowerCLI. I got the code to extend successfully the volume inside the prompt below OS once I increase it configured size through the user interface.

  Hard drive get "name VM | where {$_.} {Name - eq ' hard disk 2 "} | Together-hard drive - CapacityGB 20 - ResizeGuestPartition-confirm: $false

  My question is:

  Is it possible to increase the size put in service of a disk via PowerCLI I could run before the above code that extends the volume inside the guest OS?

  Thanks in advance for any help!

  As each correct answer, I'll have to start with "it depends".

  If this isn't the vdisk that contains the system partition, you can simply use the hard drive Set cmdlet with the CapacityGB parameter. See example 2.

  If it is the system partition vdisk, you need to use the parameter HelperVM of the cmdlet Set - hard drive .

  Note that the virtual machine and the HelperVM both must be switched off!

• The host system resources / booking via PowerCLI

  Hello chaps,

  Does anyone know if it is possible to adjust the CPU and the memory that is reserved for a host via PowerCLI?

  As far as I know, there's no cmdlet for this, but you can use the UpdateSystemResources method.

  You just need to know that the key to the Scriptures "host/system".

  $esx = Get-VMHost MyHost 
  
  $spec = New-Object VMware.Vim.HostSystemResourceInfo $spec.key = "host/system" $spec.Config = New-Object VMware.Vim.ResourceConfigSpec$spec.Config.cpuAllocation = New-Object VMware.Vim.ResourceAllocationInfo$spec.Config.cpuAllocation.reservation = 800$spec.Config.memoryAllocation = New-Object VMware.Vim.ResourceAllocationInfo$spec.Config.memoryAllocation.reservation = 800$spec.Config.ChangeVersion = $esx.ExtensionData.SystemResources.Config.ChangeVersion

• Disable Hyperthreading via PowerCLI

  Hello Chaps,

  Does anyone know a way to disable hyperthreading CPU via PowerCLI?

  I can tell you if it is enabled or not with this:

  Get-Host | Select-Object Name, HyperthreadingActive

  But now I need to disable...

  Thank you

  Dan

  Hello, dtracey-

  It looks like you can enable/disable hyperthreading on the host using the HostCpuSchedulerSystem, which is part of the HostConfigManager for the host.  So, for a single host, it would be something like:

  ## host upon which to act$strMyHostName = "myhost.domain.com"## get the View object for the HostCpuSchedulerSystem$viewHostCPUSchedulerSystem = Get-View (Get-View -ViewType HostSystem -Property ConfigManager.CpuScheduler -Filter @{"Name" = $strMyHostName}).ConfigManager.CpuScheduler## disable hyperthreading$viewHostCPUSchedulerSystem.DisableHyperThreading()
  

  You can quickly adjust this to any desired hosts, as you wish.  Note, if the method succeeds, this tells the system to not "treat Hyperthreaded as resources can be planned at the next startup the Scheduler of UC", by docs.

• Disable the host followed via PowerCLI

  Hi all...

  
  I am looking for a way to disable the host followed via powercli.

  I found one-liner of LucD to get the current state: Get-Cluster | Select Name, @{N = 'Home monitoring status'; E={$_. Extensiondata.Configuration.DasConfig.HostMonitoring}}

  And I know how to turn on/off HA: Get-Cluster | Cluster - HAEnabled game: $false

  But I'm not sure how to combine the two.

  I want to be able to quickly toggle host control without having to disable HA altogether.

  Thoughts?

  Thank you!

  You can use a where clause

  Get-Cluster | where {$_.} Extensiondata.Configuration.DasConfig.HostMonitoring} | Cluster - HAEnabled game: $false
