• Script of PowerCLI to capture ESXi cluster CPU & memory

  Hi all

  I'm having the hardest time creating a script that will give me the cluster CPU and memory. I just need something simple, if there is such a thing?

  Example of what I'm looking for:

  Name of the cluster	Ability of GHz CPU	CPU GHz used	Free CPU %

  Name of the cluster	The memory capacity	The memory used	% Memory free

  I need to present them in graphical format, but I could look to do something with a PivotTable later.

  Any help would be greatly appreciated.

  
  

  Thank you
  

  Yes, it's time the aggregation was made.

  To run against all clusters and store data of each cluster in a separate worksheet in the spreadsheet, you could do

  $fileName = "C:\Temp\cluster-stats.xlsx".

  $stat = 'cpu.usagemhz.average ','mem.usage.average '.

  $start = (get-Date). AddDays(-30)

  {foreach ($cluster Get-cluster)

  Get-Stat - $cluster - Stat $stat entity - start $start - MaxSamples 30 - IntervalMins 1440 |

  Group-object - property Timestamp |

  Sort-Object-property name.

  Select @{N = "Cluster"; E = {$cluster. Name}},

  @{N = "Time"; E={$_. Group [0]. Timestamp}},

  @{N = 'GHz CPU capacity'; E = {$script: capacity = [int]($cluster.)} ExtensionData.Summary.TotalCPU/1000); {{$script: capacity}},

  @{N = "GHz CPU used"; E = {$script: used = [int] (($_.))} Group | where {$_.} MetricId - eq "cpu.usagemhz.average"} | (Select - ExpandProperty Value) / 1000); {{$script: used}},

  @{"N =' free CPU %";} {E = {[int] (100 - $script: used / $script: capacity * 100)}}.

  @{N = "GB capacity Mem"; E = {$script: capacity = [int]($cluster.)} ExtensionData.Summary.TotalMemory/1GB); {{$script: capacity}},

  @{N = 'Mem used GB'; E = {$script: thought = [int] (($_.))} Group | where {$_.} MetricId - eq "mem.usage.average"} | Select - ExpandProperty value) * $script: capacity/100); {{$script: mused}},

  @{"N =' % Mem free";} {E = {[int] (100 - $script: thought / $script: capacity * 100)}} |

  Export-Excel-path $fileName - WorkSheetname $cluster. Name

• Need help PowerCLI with recovery ESXi host Asset Tag Info

  In the hope that someone, anyone, will be able to help me understand what I can do wrong and how to use PowerCLI to retrieve valid ESXi host Asset Tag information that appears in the tab material status vCenter. I have absolutely no problem of recovery of the serial numbers of host (sometimes referred to as Service Tags), manufacture, model, part, build, etc., but don't can't seem to be able to interrogate the current numbers of inventory number .

  None of the following attributes or property values currently returned the information required and which exists (see image below):

  Hardware.SystemInfo.OtherIdentifyingInfo [0]. IdentifierValue

  Hardware.SystemInfo.OtherIdentifyingInfo [1]. IdentifierValue

  Hardware.SystemInfo.OtherIdentifyingInfo [2]. IdentifierValue

  Hardware.SystemInfo.OtherIdentifyingInfo | where {$_.} IdentifierType.Key - eq "assettag" IdentifierValue})

  

  This is the script that I am running. I used PowerCLI Version 5.1:

  $VIServer = 'enter vCenter Server Name'

  
  # Add component snap kernel PowerCLI
  If (!) () Get-pssnapin-name VMware.VimAutomation.Core - erroraction silentlycontinue)) {}
  Add-pssnapin VMware.VimAutomation.Core
  }

  SE connect-VIServer $VIServer

  $HostReport = @)

  $VMH = get-VMHost | Get-View | % {}

  $Report = "" | Select the host name, Version, build, manufacture, model, series, Asset Tag

  $Report.Hostname = $_. Name

  $Report.version = $_. Config.Product.Version

  $Report.Build = $_. Config.Product.Build

  $Report.manufacture = $_. Hardware.SystemInfo.Vendor

  $Report.Model = $_. Hardware.SystemInfo.Model

  $Report.Serial = $_. Hardware.SystemInfo.OtherIdentifyingInfo [0]. IdentifierValue

  $ Tag = Report.Asset?

  $HostReport += $Report
  
  }

  $HostReport | Export-Csv «.\HostReport.csv"- NoTypeInformation

  Disconnect-VIServer-confirm: $false

  Ron thx.

  As far as I know, has nothing to do with PowerCLI, this is how vCenter gets this information, and how and where some HW providers make this information available.

  With the interface of the CIM, you can dump all the available information and then find exactly the tag died murdered.

  See what this returns

  import-module CimCmdlets$esxiHostname = "MyESXiServer"$HostUsername = "root"$CIOpt = New-CimSessionOption -SkipCACheck -SkipCNCheck -SkipRevocationCheck -Encoding Utf8 -UseSsl$Session = New-CimSession -Authentication Basic -Credential $HostUsername -ComputerName $esxiHostname -port 443 -SessionOption $CIOptGet-CimInstance -CimSession $Session -ClassName CIM_Chassis
  

  You will be asked the password root ESXi.

  On some of our older IBM HW, I get the following where we expect the identification sticker.

  

  But the information is there, just to another property.

  As we have already mentioned our VMworld session, exploring the CIM API.

  There is a lot of information in there

• script to find configuration of esxi host problems.

  Need a script to find if all configuration host on all issues the esxi host in the vCenter...

  example: alert, warning.

  Hello, nareshunik-

  You can consult the properties TriggeredAlarmState and ConfigIssue to display HostSystem for the VMHost objects, such as:

  Get-View -ViewType HostSystem -Property Name,TriggeredAlarmState,ConfigIssue | ?{$_.TriggeredAlarmState -or $_.ConfigIssue} | `    select name,         @{n="NumConfigIssues"; e={($_.ConfigIssue | Measure-Object).Count}},        @{n="NumAlarms"; e={($_.TriggeredAlarmState | Measure-Object).Count}}
  

  This will return just all hosts with a triggered alarm, a configuration problem or two (and the course of each):

  Name       NumConfigIssues  NumAlarms
  ----       ---------------  ---------
  myHost001                1          0
  myHost122                2          0
  myHost212                1          1
  

  How does do for you?

• WFE SharePoint causing an ESXi host cpu to boost

  Can someone help me. I recently noticed that the CPU of the host sounds a little crazy. Similar to the "image1.png" attached. I started to move each vm on the host until I've had a left vm SharePoint WFE look that makes the chart as "image2.png", I have 2 sharepoint vm causing my host to act this way. If I migrate all the vm on the host, leaving one of these virtual machines SharePoint history is the same. However if I move SharePoint boxes outside the host CPU performance table goes back to a more normal view as "image3.png" environment have 6 host with 2 Sockets, processor and 12 cores per socket. Hyperthreading is enabled. Most of the virtual machine have 2 vCPU and 4 GB of ram. However, SharePoint boxes are running 4 vCPUs and 16 GB of RAM. "sharepointcpu.png" is an example of the use of the processor on the computer virtual SharePoint. My question is this something a web front end would normally? Also has anyone seen this type of behavior? If Yes is something worrying? I have also attached a host esxtop output.

  Hello

  all seems well in esxtop according to this post: is why % WAIT so high in esxtop?

  Can you provide us with more data from your operating system? The CPU of fortification in both BONE or is it idle? That would be the main point from as we saw only the level of the hypervisor to date. vCPUs crosses around physical processors on the same NUMA node where they can be better planned then maybe that's why you see so many spikes. Also, I see that the virtual machine is not much loaded - you can try decreasing vCPUs we will say 2 and repot the back?

• script of PowerCLI to capture cpu usage statistics & individual VM mem

  Hello

  Is it possible to know or to get cpu usage statistics & mem of individual virtual machines for the last 5 days through PowerCli and export to CSV report

• Invited 3.5u4 swap ESXi host and memory size

  As seen, no swap no used. Why VI customer counters and swap file size differs so much use of guest operating system counters.

  Hello

  You are looking at two different levels of memory usage. VI customer, you can read information about the actual use of memory and swap ESX. It differs generally you can read from within the guest for example OS Linux. VM swap file (not asked) if used by VMkernel in situation when the assertion of memory occurs. Lack of memory is mapped in the Exchange. It is the last resort and causes significant performance degradation.

  Guest os swap is "high" this VM swap. It is entirely managed by the guest operating system. It size is based on the memory configured for VM and guest OS configuration. Only the situation when VMkernel can affect the exchange of comments is the balloon pilot. It is a breakthrough of technical recording memory that allows ESX to "say" the guest OS some free memory and use more swap file (Exchange of comments!). Freed memory can be reclaimed by VMkernel and used by other virtual machines. This driver is available for the guests with VM Tools installed.

• Share of CPU between ESXi hosts in a cluster?

  Is it possible to configure a cluster with a pool of CPU resources such as all CPUS of all ESXi hosts in the cluster are in the pool and if a virtual machine starts using more CPU that's current host has it can draw another ESXi host CPU to deal with?

  A virtual machine can use CPU only from the host where the virtual machine works... There is no way to allocate CPU of multiple hosts to a single virtual machine.

• script to find the local TSM and TSM remote is activated on the esxi host

  Need to generate scripts to find on which esxi host in the vcenter is enabled for Local TSM and TSM remote...

  Hello, nareshunik-

  Thanks to the handy Get-VMHostService cmdlet, you can quite easily get this info:

  Get-VMHost | Get-VMHostService | ?{"TSM","TSM-SSH" -contains $_.Key -and $_.Running} | Select VMHost,Key,Running
  

  The result is something like:

  VMHost    Key      Running
  ------    ---      -------
  myHost01  TSM         True
  myHost02  TSM         True
  myHost05  TSM         True
  myHost05  TSM-SSH     True
  

  TSM is the local service of TSM or "ESXi Shell", and the TSM - SSH service is "SSH".  How does do for you?

• CPU/memory of the ESXi host totally access & usage and temp CPU with PowerCLI.

  Dear all,

  I am struggling with the CPU/memory reading of the host completely & information about the use of PowerCLI and the temperature of the CPU is also very useful for me. I used "Get-VMHost-name" to get VMHost to object, but cannot get its properties such as CpuTotalMhz, CpuUsageMhz, MemoryTotalMB, MemoryUsageMB.

  And also do not know which object has temporary information of the CPU. Thank you!

  You probably have a fairly old PowerCLI version (4.0).

  We'll see if the upgrade solves a number of these problems.

• PowerCLI script for join ESXi hosts to Active Directory

  Is there a script that I can run to join the ESXi hosts Active Directory?  I have over 100 guests that I need to join AD and want to add it script instead of using the GUI VC.

  Thank you!

  Matt

  You can browse all of your servers, but you would need to make fully automated, is get the credentials somewhere.

  You have different passwords on all ESXi servers?

  In this case, you could do something like that

  $cred = get-Credential # prompt for user and password

  Get-VMHost | Set-VMHostADDomain -ADJoin:$true -Domain$domain-Credential $cred

  If you do not have the same account/password for all servers ESXi, you want probably asked for each host.

  You could possibly temporarily store in a file and read this file.

  $accounts = @ {}

  Import-Csv "C:\accounts.csv" | %{

  $accounts [$_.hostname] = $_.password

  }

  Get-VMHost | Set-VMHostADDomain -ADJoin:$true -Domain$domain-User root -Password $accounts[$_.Name]

  The CSV file contains 2 columns, called host name and the other called password.

  We read the CSV file and store the passwords in a hash table, where the host name is the key.

  We use the hash table to fetch the password of the Set-VMHostADDomain cmdlet tree.

• Script to check the version of Cisco VEM on ESXi host

  Hallo,

  I need help, a script to check and report in a CSV file, the version of Cisco Nexus 1000v VEM on all ESXi hosts connected to a vCenter.

  Basically, "vem version - v" but for all the ESXi hosts connected to a vCenter.

  Thank you

  Joseph

  I suspect you could use PowerShell v1, in this version that the Export-Csv has not had the UseCulture parameter.

  Try to run the script without this parameter.

  But I would strongly suggest to upgrade your version of PowerShell (v3 is available)

• Can I use the total amount of resources (cpu/ram) of two esxi hosts if I place a cluster so that a single VM gets all resources?

  I use vCenter 5.1 with two esxi 5 guests, both exactly the same (Evga SR - 2 pc with two Intel x 5670 each) with the exception of the disk storage. Processor x 5670 a 12 hearts if HT is enabled. Since then, I have 4 of these processors that would be 48 cores. Each processor is clocked at 4 GHz for a total of 16 GHz. Each host would also 24GO of total Yes 48 GB of ram.

  I doubt that this is possible, but what I want to do is to install a virtual machine like Win 7 x 64 and give all these resources to it... all of them (perhaps leave some carrots and ram aside for guests of esxi, of course). This vm is run to 16 GHz? It would be nice if we could create a cluster with a Setup like this and give the "total available resources' for a single virtual machine running on a esxi host.

  I doubt that this is possible because I've tried that before and it wouldn't let me create a virtual machine with this number of nuclei or ram because he said that they were not available or something... as if to suggest that I can only use the total amount of resources to AN esxi host.

  There may be another way I could give this 16 GHz machine?

  Could not assign more resources to a host to a virtual computer.
