• Script Get-stat for VM Perfomance - Questions

  I am writing a script to get data on our virtual machine performance of the measures of depth for CPU and memory.  Its a great project task I have to do for our mgt and so I am writing a script extremely important and vital for our company.  I use the command get-stats and feedback from the messages I posted about get-stat in particular lucd and lebouf who have been very helpful.  But I have collected their answers and writes the script below.  Currently, it must be used with an argument, but I can change it later.  It also uses many counters of cpu and memory that is why it is a long script.  But I have a lot of questions on the script before I run it, I need to be clear with the data I receive in return.  The script is below:

  $vm = $args

  $vmguest = @{N = 'operating System'; {E = {.osfullname (get-vmguest - VM $_)}}

  Get - VM $args | where {$_.} PowerState - eq "Receptor"} | `

  Select name, NumCpu MemoryMB,

  @{N = "Mem.Usage.Average"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.usage.average | Measure-object-propriete value - average). Average}},

  @{N = "Percentage of use memory Maxiumn"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.usage.maximum | Measure-object-propriete value - average). Average}},

  @{N = "Memory use Ko"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.consumed.average | Measure-object-propriete value - average). Average}},

  @{N = "Memory status"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.state.latest | Measure-object-propriete value - average). Average}},

  @{N = "Memory Swapin average ko"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.swapin.average | Measure-object-propriete value - average). Average}},

  @{N = "Memory Swapout average ko"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.swapout.average | Measure-object-propriete value - average). Average}},

  The questions I have are:

  The first question is I want the stats to be based on the last 7 days, so I used the .adddays (-7).  It would give me the last 7 days stats?

  In my settings of virtual center statistics, I have all interval times checked.  So if I want last 7 days stats, I would use the samples for the interval of 30 minutes duration.  Also I have not used all interval parameter in the get-stat, so my samples will be based on the interval of 30 minutes.  Is this correct?

  Also, I have not used the maxsample interval, so by default I get to use all the values in the sample, and measures will give me the average of all samples (duration 30 min) values in the last 7 days.  Is that correct. ?

  Another key question is that is it possible to get readings of samples for only Monday to Friday, from 06:00-18:00, as this is when the virtual machine is used.  I don't know how this can be done and how it can be incorporated in the above script.  Is this possible to do?

  Also about the measure-object cmdlet, I used to all counters, as for the average values of use of cpu and memory.  I also use counters for cpu and memory max.  Would I need to use the average value of the object of measures to this end, as this counter will give me the max value for cpu/memory for all 7 days, which will be a single value, because I want to know the max value, it achieved, so I don't know if I have to use measure-object with these counters, do I need to use?

  About the ready CPU meter I use, also gives the value in millseconds.  Is it possible to get loan from cpu percentage value as we see in ESXTop because it is easier to understand for the cpuready.  I don't see any counter loan as a percentage of the CPU.  Is it possible to get a value for it.

  With the - equal Start parameter to specify that you want the values from 1 day back.

  This means that you will get the values historical interval 1 and the period interval 5 minutes ago.

  It is the HI1 interval in the scheme of part 1.

  When you specify not one - Start parameter and - finishing you will in effect of the values of historical interval 4, which has a period of 1-day interval.

  In a next blog post, I will talk about default values in the cmdlet Get-Stat.

The time interval can be anything, I'd like to see the same values that manifest slot for power under the tables of performance of an esxi host.

  Any help would be appreciated.

• Get-stat - disk for virtual machines on NFS data warehouses

  Hi all

  Through work for VMs on NFS data warehouses get-stat-disc?

  $myVM | Get-stat - disc

  Doesn't seem to work for VMs on NFS data warehouses, but that works for VMs on VMFS data warehouses.

  After a presentation of VMware to http://webcache.googleusercontent.com/search?q=cache:h78Db7LqHcwJ:www.slideshare.net/vmwarecarter/powercli-workshop+%2Bget-stat+%2Bnfs & cd = 2 & hl = in & ct = Europeans & gl = at the & source = www.google.com.au

  «WARNING: NFS performance statistics are not available (to come in a future version of vSphere).»

  When these statistics are available for NFS data storage?

  Kind regards

  marc0

  The answer is in the property of instance data that Get-Stat returns.

  (1) get-Stat ==> canonical name of the LUN on which disk the hard

  (2) get-Stat virtualdisk ==> The SCSI id of the virtual disk inside the VM

  (3) get-Stat data store ==> the name of the data store

  (1) you give statistics for view virtual machine i/o activity starting from the LUN. For a VM with several virtual disks on the same data store, this will display the total IO statistics. And it will also include i/o generated by another VM on the LUN as swap, Flash files related...

  (2) gives statistics for 1 specific virtual disk of your virtual machine

  (3) statistics of e/s of your VM to a specific data store. Interesting when you have a store of data with multiple extensions (multiple LUNS)

  I hope that clarifies it a bit.

• get all the date of end of months between two dates

  Hi all, I'll try to find together the date of end of months between two dates.
  I have the following data in a table
  
  WITH AS's Data1
  (
  SELECT To_Date('4/30/2009','mm/dd/yyyy') dt, 'TEST' lname FROM dual UNION ALL
  SELECT To_Date('5/01/2009','mm/dd/yyyy') dt, "TEST2" lname FROM dual UNION all
  SELECT To_Date('5/02/2009','mm/dd/yyyy') dt, "TEST3" lname FROM dual UNION all
  SELECT To_Date('5/03/2009','mm/dd/yyyy') dt, "TEST4" lname FROM dual UNION all
  SELECT To_Date('5/04/2009','mm/dd/yyyy') dt, "TEST5" lname FROM dual UNION all
  SELECT To_Date('5/05/2009','mm/dd/yyyy') dt, "TEST6" lname FROM dual UNION ALL
  SELECT To_Date('5/31/2009','mm/dd/yyyy') dt, 'TEST7' lname FROM dual UNION all
  SELECT To_Date('6/01/2009','mm/dd/yyyy') dt, 'TEST' lname FROM dual
  
  )
  
  I would like to write an application that gives you all the end date for months between two dates
  for example, if you give the date 9/1/4 and 5/6/9, the output should be
  

  DT          LNAME
  -------------------
  4/30/2009   TEST

  IF I give you the dates 01/04/09 AND 01/06/09, THEN output should be

  DT          LNAME
  -------------------
  4/30/2009   TEST
  5/31/2009   TEST7

  as you can see, I want all the end dates of months between two dates by giving the output.
  
  If I give you 06/05/09 and 05/06/09, and then does so no output because there is no end of month between these two dates.
  Similarly, if I give you 30/04/09 and 30/04/09 then output should be 30/04/09 because it is an end of month date
  
  anyone can help to write a query. Thank you very much

  Jin
  Not sure if you need subquery, analytical functions for this.
  According to me, which should solve your purpose.

  WITH data1 AS
  (
  SELECT To_Date('4/30/2009','mm/dd/yyyy') dt, 'TEST' lname FROM dual UNION ALL
  SELECT To_Date('5/01/2009','mm/dd/yyyy') dt, 'TEST2' lname FROM dual UNION all
  SELECT To_Date('5/02/2009','mm/dd/yyyy') dt, 'TEST3' lname FROM dual UNION all

  SELECT To_Date('5/05/2009','mm/dd/yyyy') dt, 'TEST6' lname FROM dual UNION ALL
  SELECT To_Date('5/31/2009','mm/dd/yyyy') dt, 'TEST7' lname FROM dual UNION all
  SELECT To_Date('6/01/2009','mm/dd/yyyy') dt, 'TEST' lname FROM dual 
  
  )
  select distinct last_day(dt) dt,lname
    from data1
   where dt between &start_date and &end_date
     and last_day(dt) <= &end_date
  

  also, i have another request. how would i do this without using the data i provided. lets say,
   i tell you, give me alll the months end between two dates using dual in the from clause of a query.
  how would you do this in a query or pl/sql? thanks again
  

  Can be like that

  with data1 as(
  select &start_date+level-1 dt from dual
  connect by level <= &end_date-&start_date+1)
  select distinct last_day(dt)
    from data1
   where dt between &start_date and &end_date

• Cluster data warehouses

  I would like to create a dashboard that displays a list of all VMWare clusters and for each handset display data warehouses that are used for each of them. Looking for a way to create the dashboard without slipping each store data in the dashboard.

  1 is it possible with a query of the user interface?

  Data > VMWare > centers > (name datacenter) > cluster > (cluster name) > ESX host > (host name) > storage > data warehouses

  If you want the names and what may not be a little cleaner that I would try this, it also removes the need for the additional query keep things all neat.

  cluster = server.get ("QueryService").queryTopologyObjects("!) VMWCluster')

  output =]

  (cluster in clusters)

  {

  data warehouses = cluster.esxServers.datastores

  for (data in data warehouses store)

  {

  map = [VMWCluster:cluster.name, VMWDatastore: datastore.name]

  output. Add (Map)

• 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

  Kind regards

  [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

• Average values for separate sets of data graph XY multiplot

  Hello

  I'm using Labview 2010 and I'm a bit of a novice, unfortunately.

  So I am currently trying to get average values of the three plots I have on a multiplot XY Chart. I thought the best way to achieve this would be to use the express VI of statistics, but when I try to wire the data I need for this I can get statistics for a set of data and not the other two.

  I don't know how the separately on data sets, as it is not a table.

  If anyone can help me, it would be much appreciated. Sorry for the probable simplicity of the question.

  (The program is basically an ODE Solver, which then displays pressure at different places in a bioreactor).

  In the small LOOP where you have data of y for each parcel in the form of a 1 d table, add a "mean.vi" in the math palette: statistics. AutoIndex the output on the edge of the loop to get a table 1 d containing three ways.

  (In addition, a lot of your code could be considerably simplfified. You can [i] connect directly to the structure of the case and a case of '0' and the other, by default. Better would simply initialize the shift, no means required register. Index table is resizable, so you don't need to a single instance on the lower right corner. Wouldn't be easier to just get the latest column and it wire back the entrance inside the structure cases via the feedback node? No need to "subset of table to replace").

  You have forgotten to attach a Subvi, so we can't really test.

• get guests basic stats and data warehouses

  Hi all

  I am totally new to vcenter and power shell, so please, be gentle on my stupid questions. I'm desperate to compile a script to get the weekly statistics for host, County of vcpu and data store memory space and export it to a csv file. Numbers so very basic for each host computer and the data store. Here's what I have so far based on blogs of the LucD generous. It would be great if someone of you can help me realize what is wrong...

  It took a lot of time for me to understand what are the parameters I need and I'm sure that they are correct, but the syntax is killing me now. Basically, I realize there is something wrong with my variables since nothing is exported to the file you want, but I do not know how to define variables and their attributes. And the error was "impossible to replace the host variable because it is read-only or constant", while other properties such as "name", "mem", etc.

  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

  Oliver

  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.
