• 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}},

  @{N = 'Memory reserved MB capacity'; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.reservedCapacity.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.

  I'm considering buying a MacBook Pro 15 inch. I use programs such as Stata, for big calculations. What is my best option?

  Either of the 15 "MBPr come with 16 GB of RAM and because it appears that RAM is paramount for Stata then one of them should be able to manage it.

  Is the portability of paramount importance for you? If this isn't the case, you might consider an iMac. You get more for your money from a laptop to a desktop computer. In addition, the RAM on the iMac can be improved if need more later. From what I've read on Stata resembling an important consideration.

• Get-Stat for use of the power of the ESXi Server

  Hi all

  Need your help to get a script to capture power consumption/use of an esxi host. I checked the command get-stat, I don't see any special argument as energy consumption in check for the host entity. 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.

  Thanks in advance

  Try like this

  10 P 002 003 004 005

  $entity = get-VMHost-name MyEsx $stat = "power.power.average". Get-stats - $entity - $stat - Realtime - MaxSamples 1 Stat entity

• The use of objects multi-state for the next stage of the course 9

  In my old clumsy e-Learning authoring tool, I could create a slide with several steps. You would click the button Next to display text and graphics.  When you get to the last step, the next step button disappears, so that you know that you have completed. How can I make this work with multi-state Cap 9 objects?  I created an object with 3 States multi-state. I created a button with an action go to Next State.  It is fine until you get to the last State.  If you click the button again, it starts again with the first State.

  Yes, I can create several buttons. But I really just want a button called next step which disappears after posting the last State.  The user would know that she had displayed all the steps.

  Any suggestions are welcome.  Thank you.

  Jeanne M

  Here is a sample script:

  

  This has been implemented for 6 States (for a container of text, the Normal State is an empty form).

  There are 2 user variables:

  • v_counter has a default value of 0
  • v_max is the number of States, you can replace it with the literal '6' or you need to

  The first decision "done" check if the counter reaches the maximum value (v_max). If this is the case all States should have been disclosed, and it should end the loop. That's why this decision will disable the button used to change States (SB_StateTrigger) and here also to change its status to an invisible state (AfterLoop). Upon return to the slide, the State will be back to Normal (visible), and simply activate the button again. You can replace this with a simple action to hide as well if you want.

  If the first decision is not true, there are still reports to be shown and the counter is incremented.

  All 6 other decisions are similar (I collapsed 2 of them): they will test the value of the counter and show the associated State. I used to state3 on a common standard. This makes it possible to use exactly the same advanced also action if the total number of States is less than 6. Simply change the value of v_max.

• Get-stat for monthly trends of data warehouses

  Hi all

  Long time lurker of time,

  I have not been using PS for long and mostly just pin out one liners for things like "whats connected to X", etc.

  I'm trying to output a file that I can put in excel and create configured vs used graphics is the idea.

  I would like to get this down so I can manipulate to other entities.

  I can wrap this around a foreach loop that I can usually understand.

  With get-stat, I noticed that he gets a single value, then the other so the MetricID is evolving, so I can't just select the property.

  I have a script already where I show the last value and then put them all on the same graph, but it would be cool to have a chart with the data store to see the trends.

  We have vcops, but I find the graphics a slow process, because we have dozens of warehouses of data around the world.

  It's my script simple I must then cut and paste the values into additional columns, but who wants to do it manually

  I can do something like this

  $todayMidnight = (get-Date-time Minute 0 - 0 - 0 second)

  $Startmonth = - 1

  $metrics = "disk.capacity.latest", "disk.provisioned.latest", "disk.used.latest".

  $datastore = "vm_production01".

  $arrds = get-datastore. WHERE-object {$_.} Name - like $datastore}

  $a = get - Stat - $arrds - Stat $metrics entity [0] - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight | where {$_.instance - eq ""} | Sort the timestamp | Select the timestamp value

  $b = get - Stat - $arrds - Stat $metrics entity [1] - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight | where {$_.instance - eq ""} | Sort the timestamp | Select the value

  $c = get - Stat - $arrds - Stat $metrics entity [2] - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight | where {$_.instance - eq ""} | Sort the timestamp | Select the value

  $fin = $a + $b + $c

  $fin = $a + $b + $c

  $fin | ConvertTo-Csv | Out-file C:\support\scripts\development\datastoreusage.csv

  See the attachment for the final goal.

  I don't know if I need to create a custom object to accomplish, if someone could help me that would be great.

  and none of the useful articles where I can learn to do it, I'm almost finished powershell in a month of meals but I do not think that this is covered

  Thank you all

  To run this for all your storage data and then create a spreadsheet with the data store, you can use the function of export-Xlsx .

  The script should look like this

  $todayMidnight = (get-Date-time Minute 0 - 0 - 0 second)

  $Startmonth = - 1

  $metrics = "disk.capacity.latest", "disk.provisioned.latest", "disk.used.latest".

  $ds = get-Datastore

  $xlsxPath = "C:\ds-report.xlsx".

  Get-Stat - $ds - Stat $metrics entity - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight |

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

  $dsStats = $_. Group | Group-object - property Timestamp | %{

  New-object PSObject-property @ {}

  Timestamp = $_. Name

  'Capacity (GB)' = [Math]: Round (($_.)) Group |

  where {$_.} MetricId - eq "disk.capacity.latest" - and $_. ({Instance - eq ' '}). Value / 1 MB, 2)

  'Allocated (GB)' = [Math]: Round (($_.)) Group |

  where {$_.} MetricId - eq "disk.provisioned.latest" - and $_. ({Instance - eq ' '}). Value / 1 MB, 2)

  'Used (GB)' = [Math]: Round (($_.)) Group |

  where {$_.} MetricId - eq "disk.used.latest" - and $_. ({Instance - eq ' '}). Value / 1 MB, 2)

  }

  }

  $dsStats | Tri-objet-Timestamp property |

  Select the Timestamp, 'Ability (GB)', 'allocated (GB) ', ' used (GB) |

  Export-Xlsx-path $xlsxPath - AppendWorksheet - WorksheetName $_. Name of the end - SheetPosition

• How to use the API to perform a "Power on and Force Recustomization" 1.5?

  With the help of VMWare vCloud Director, when the virtual machine is turned off, I have the menu ' power on and Force Recustomization "to turn on the machine and do some recustomization work such that reset the administrator password.

  However, I can't do this using the API. The vm/vapp. PowerOn() has no parameters. The vm/vapp. Deploy (true, 0, true) can (re) deploy the vm/vapp and plugged. But the recustomization never runs.

  My code can update the section "customization of the OS invited." I can see it in vCloud Director. And then if I manually ' power on and Force Recustomization ", the machine will be powered on to reset the password. But if I use the above codes, none of them works. So, I conclude that the problem occurs in the sending of the statement of "Power on and Force Recustomization ' using the API.

  Any help will be evaluated.

• Possible to use the IDE controller card in ESXi 4.0

  I have a lot of hard disks IDE that I would use in my ESXi host, but I don't have a motherboard all IDE interface is SATA and I have the DVD player plugged into that. There are more available on this cable plug, but it is unusable as a result of the configuration of the necessary training and the fact that the right ribbon cable won't reach it. So I took an old PCI Ultra ATA/133 (ITE IT8212 ATA Raid Controller) and plugged into a slot available PCI and then attached to one of my IDE drives... But when I rebooted, it is not found on the system. So I looked around, and it seems that these cards are not supported? Go figure. If these cards are not supported, then I'm looking for a really intelligent person who has found a way to make these devices run. Correct me if I'm wrong, but VMWare seems to have decided to simply drop all legacy devices together... Why? Is he really consider a lot to allow older device drivers? Yes, I'm just a user trying to do something my old camera, so I understand that I am part of a very limited audience which is not the target. However, I am also pushing my virtualization Initiative at work and am just getting up ESXi on one of our older PowerEdge servers with plans to do the same thing on our new r710 if bosses are satisfied by tests on the former, and my house already tests helped me identify some limitations of the equipment of PE2800 at work , and I think they would also attract large scale as possible.

  For the laboratory and home, try the steps in VM-HELP - install ESXi 4.0 on an IDE drive.

  When I check in the internet I found a few points and need clarity also by the following.

  -It is recommended that this switch Redo log 5 times maximum per hour, but I have this time of maximum peak about 100 redo log changes occur.

  -It is recommended to have the large size of the Redo log. But I have 3 Group of redo and each size is 50 MB by default.

  -My group of Redo log not multiplexed and it by default with each group have only a single Member

  Group 1 - D:\APP\ADMINISTRATOR\ORADATA\AWSPROCESS\REDO01. JOURNAL

  Group 2 - D:\APP\ADMINISTRATOR\ORADATA\AWSPROCESS\REDO02. JOURNAL

  Group 3 - D:\APP\ADMINISTRATOR\ORADATA\AWSPROCESS\REDO03. JOURNAL

  And advised by experts with add that again group will give more performance in the other location. Is it mean that I need to add the Redo log as a different group, player or Redo Log itself I need to replace the other location.

  Say in the end, My Live server works with the location and size of restore default. I'm trying to create a better way and get all confused

  How to do it perfectly.

  Experts, please share your comments to my environment to log redo instance as better through your comment or recommended weblink based on my above needs, or a document.

  Thanks in advance, if you need more information to help me, then ask me, I'll share you.

  Hello

  You can't resize an existing redo log group.

  You will need to create 3 new redo log groups and drop old log redo (with 200 MB size) groups.
