• Average usage of the CPU with get-stat

  With get-stat, I can get average use of the processor in MHz using the metric usagemhz.

  However, by default the maximum and minimum values in MHz is not in data points from 2 months ago.  That's fine if I want to just average, but I also need average peak values.  The average maximum CPU usage is possible with powerCLI?

  The thing is that when you have found these averages and you do that a day or a week of a data value is not enough to really give you a true picture - you need 2 - 3 months.  Can Haw I achieve this with PowerCLI?

  1. you can easily adapt the cmdlet Get - VM to produce the result for 1 or a limited set of the virtual machine

  For example:

  Get-VM-name MyVM | Select...

  Returns the result for 1 computer virtual called MyVM

  If you do

  Get-VM-name my * | Select...

  It returns results for all virtual machines whose name begins with "My".

  2. that's because Select-Object generates a hash table, and by default PowerShell displays like that hash tables.

  To get only the value real exchange the last select like this

  ...

  } | Select AvgCPUMhz - ExpandProperty

• Get some pics of use with get-stat

  In vCOps, you have the concept of the 95th percentile, which allows you to get the 'average of the peaks '.  The idea is that you're taking a set of data points and get the 95th percentile of them for something like the CPU demand MHz for a set of virtual machines.

  Transfer to PowerCLI - in powerCLI rely on database of vCenter data points that were on average through the stacks.

  The problem is the following:

  If I use that data points in the last hour of the statistics 'real-time', my 95th percentile is made with points of data representing the polling intervals of 20 seconds.

  When I move the data points "Last day", then I use averages of these 20 seconds, question marks to get just the data points that represents the average of the 5 minute intervals.  In other words, I've already lost a part of my high and low data points in the update rollup and by 5 minute data are smoothed out now to be an average of the 20 seconds that I had.

  Then spend a week and I have stacks of my data points "last day."  Now my data points are smoothed even further.  Among all of the points of data to the left now, I lost still more ups and downs in my every 5 minutes, and I have only the averages for these intervals of 5 minutes in my 30 minutes of interval data points.

  The point is that the further I go back, the pics more and valleys I lose as rollups toning their stop.  So if I do the calculation 95th percentile, over the period of time, I'm comment less than a true representation of the 95th percentile I don't really have.  Because I work off the coast of data where the peaks and troughs have been rounded more for fewer data points.

  By LucD, who proposed a way to get the 95th percentile:

  https://communities.VMware.com/thread/460129

  I can get a rough estimate of the 95th percentile.  However, it appears (correct me if wrong) that I'll be back a month or two or three months or one year that my 95th percentile will be reduced and a balance budget actual 95th percentile and more a 95th percentile of the average instead of a 95th percentile of actual performance data. and probably further from vCOps make account.

  Any proposed solutions to this problem?  The goal here is to use PowerCLI for model truly what my 'tip' periods look like for an application of VMs CPU when for example, at the end of the month, everyone makes their treatment.

  Although there is no official took in charge methods to extract data from the DB vCOps, it is possible.

  Clinton did a post on this, see informal VMware vCenter Operations Powershell Module

  And of course, there will be a chapter in vCOps in my next book, that I mentioned earlier

• VM return do not all data with Get-Stat

  Hello

  I'm having a weird problem with a script to output report PowerCLI (attached), there are 3 machines that do fit all the data (the exit is on the attached .txt). This is probably a simple solution, but I don't know how I could reproduce it in my lab and I don't want to mess with the customer's production environment. Maybe some of you guys have concocted with something similar.

  I have powershell v.4, PowerCLI 5.1 running on a windows 7 Pro 64-bit

  Thanks in advance for your ideas.

  It seems that the jobs of aggregation have stopped running.

  For the import of these data to our central database, the formats must be uniform.

  Someone at - it an idea to get the uniform format?

  Thanks in advance

  Concerning

  Why don't you use the solution in Use-Culture - Culture culture - Script {scriptblock} ?

  You do all the writing to your database in 1 selected (for example en-US culture).

  This way all your date and and digital formats have the same layout.

• "Mem.Usage.Average" against the total aggregate of cluster host memory

  Please see the attachment for the whole story.

  Please give me a sanity check on this. I used the "Mem.Usage.Average" as a % against allocated VM MemoryMB. The sum of these calculations escaped by far the actual calculations of the vCenter % memory-based. So, I changed my calculations that you see in the worksheet to use the 'Mem.Usage.Average' against the total aggregate available on all hosts in the cluster. This amount came to less than 1% of my calculations based on vCenter GUI. Am I right against the total aggregate memory cluster host instead of against VM memory assigned using 'Mem.Usage.Average '? Thxs-

  

  SDK is not clear on "total configured memory available or". https://www.VMware.com/support/developer/converter-SDK/conv55_apireference/memory_counters.html Part description of memory used as a percentage of the total configured or available memory.

  
  

  $start = (get-Date). AddDays(-5)

  Get-cluster-location ActualClusterName | Get - VM | Where {$_.} PowerState - eq "Receptor"} @{N = "Mem.Usage.Average"; E = {[Math]: round ((($_ |))} Get-Stat - Stat mem.usage.average - start $start - $finish - IntervalMins 1800 - MaxSamples finishing (250) | Measure - Object - average value). Average), 2)}}"

  
  

  Cluster is 6 hosts with 128G per host for total of 768G (786432 MB of RAM), there are 118 powered on virtual machines

  
  

  
  

  for me the SDK says that percentage reflects the relationship between the memory 'active' in the virtual machine against the memory configured for the virtual machine.

  A configured with 8 GB of memory virtual computer that has 'use' of 25% is actively using 2 GB of memory.

  

  I think that your numbers you get for VMS are biased because of the great period of time during which you take the average (see previous answer).

  You can cross-check the mem.usage.average with the mem.active.average.

  In the following code, I calculate the different 2 meters actual memory used by the virtual machine.

  $clusterName = "mycluster.

  $stat = 'mem.usage.average ','mem.active.average '.

  $vm = get - Cluster - name $clusterName | Get - VM | where {$_.} PowerState - eq "Receptor"}

  $stats = get-Stat-entity $vm - Stat $stat - Realtime - MaxSamples 1

  $stats | Group-object - property {$_.} @entity.name} | %{

  [PSCustomObject] @ {}

  VM = $_. Group [0]. @entity.name

  MemoryMB = $_. Group [0]. Entity.MemoryMB

  MemUsagePerc = $_. Group | where {$_.} MetricId - eq "mem.usage.average"} | Select - ExpandProperty value

  MemUsageMB = [int]($_.) Group [0]. Entity.MemoryMB * ($_.) Group | where {$_.} MetricId - eq "mem.usage.average"}). Value) / 100

  MemActiveMB = ($_.) Group | where {$_.} MetricId - eq "mem.active.average"} | Select - ExpandProperty Value) / 1 KB

  }

  }

  The result shows a specific virtual machine, these two numbers are close enough to be considered the same imho.

  That they should be in fact, the mem.usage.average is derived from the mem.active.average.

  

• MEM.usage.Average Question

  We make sure that our ESX clusters are run under 70% memory usage.  Is it possible to subtract 70 (percent) memory usage in the following script?

  now Questions or clarification;

  1.

  NET. Throughput.usage.Average

  Use of net debit

  Kbps

  The use of band current network bandwidth for the host

  Why then the o/p shows MBPs & not Kbps

  2. If a second on the last day 1 as the VM did network traffic means 2.16 for vm y?  Does include entering & leaving them both?

  Thank you

  To get the unit use the property Unit of or the returned samples.

  The net.throughput.usage.average metric is the sum of the net.received.average and net.transmitted.average parameters.

• Get-Stat & weighted average

  When I run

  Get-ResourcePool -name "RSNAME" | Get-Stat -Stat mem.consumed.average
  

  Powercli is a weighted average (weighted average arithmetic - Wikipedia, the free encyclopedia)? Or I have to take into account that a VM can have data for each interval points, IE the VM did not exist at that time?

  It is a weighted average return.

• Average read get-stat - virtualdisk.read.average stat?

  Hi all

  I want to use the metric virtualdisk.read.average to calculate the average read speeds per virtual disk to a virtual computer in the last 24 hours (using the 5 min interval)

  [1]

  I want to calculate the average in * every * instance and then add these individual averages until you get the desired amount.

  For example (using real-time output just for example only, I want 24 hours actually):

  MetricId unit Insta timestamp value
  NCE
  --------                ---------                          ----- ----     -----
  VirtualDisk.Read.Ave... 13/05/2011 19:39 6 Kbps scsi0:0
  VirtualDisk.Read.Ave... 13/05/2011 19:38:40 Kbps 11 scsi0:0
  VirtualDisk.Read.Ave... 13/05/2011 19:38:20 KBps 39 scsi0:0
  VirtualDisk.Read.Ave... 13/05/2011 19:38 431 Kbps scsi0:0
  VirtualDisk.Read.Ave... 13/05/2011 19:39 10 Kbps scsi0:1
  VirtualDisk.Read.Ave... 13/05/2011 19:38:40 Kbps 0 scsi0:1
  VirtualDisk.Read.Ave... 13/05/2011 19:38:20 5 kbps scsi0:1
  VirtualDisk.Read.Ave... 13/05/2011 19:38 0 Kbps scsi0:1

  Average (6 + 11 + 39 + 431) = 121.75

  average (10 + 0 + 5 + 0) = 3.75

  Total liked: 121.75 + 3.75 = 125,5

  What is the best way to achieve this? (Unfortunately there is no global instance as with the network and cpu.usagemhz parameters)

  [2]

  For the calculation of the IOPS / s, if you use the metric datastore.*, OR as the virtualdisk.*, is the following statement, 100% good:

  (a) virtualDisk.number [Read |] Write] Averaged.Average will calculate the OPS are / s generated by the virtual machine

  (b) disk.number [Read |] Write] .summation will calculate the OPS are / s that hit this particular data store (useful to see how busy is a data store - but will not provide any info on a single virtual machine (unless by chance, there is only a virtual computer on this data store special))

  [3]

  How to use virtualDisk.number [Read |] Write] calculate the IOPS / s for a given virtual machine?  Depending on the issue [1], to each VMDK, PAHO are / s on average individually and then add the averages for overall IOPS generated by this virtual machine in the last 24 hours?

  Concerning

  marc0

  Kind regards

  marc0

  [1] use the Group-Object and Measure-Object cmdlets for this.

  For example

  $vm = Get-VM MyVM $report = @()
  $stats = Get-Stat -Entity $vm -Stat virtualdisk.read.average -Start (Get-Date).AddHours(-12)
  $stats | Group-Object -Property Instance | %{
      $row = "" | Select Instance,Average
      $row.Instance = $_.Group[0].Instance
      $row.Average = ($stats | Measure-Object -Property Value -Average).Average
      $report += $row}
  $report $total = ($report | Measure-Object -Property Average -Sum).Sum
  Write-Host $vm.Name $total
  

  This will calculate the averages per virtual disk and add the averages together

  [2] see my post get PAHO are / s maximum .

  (a) Yes, provided that you add the OPS are / s for each virtual disk total

  (b) No, if you run the Get-Stat for an entity that is a virtual machine, you will get the statistics for this specific VM disk.

  The metric is available for HostSystem and VirtualMachine. See the column of the entity in the drive settings page.

  [3] Yes

  CC for flash doesn't support AS2, so perhaps that is the reason.  CS6 (or earlier version) supports AS2.
