• vCenter 5.1 having issues with snapshot size alerts

  Hello world
  I have a problem regarding the sending of alerts by e-mail when vm snapshot size exceeds a certain size. (in fact, any size with problems)

  She doesn't send traps, ignoring what I did come in like it size and spamming my Inbox.

  Go to alerts vcenter - new alarm - monitor: VMS - monitor specific conditions or State...

  Trigger: Condition: above

  Size of Snapshot in VM (GB): WARNING: level 1

  Snapshot in VM (GB) size: alert level: 2

  Send email to: myself

  When I click on ok. I have tons of emails from vcenter which all my virtual machines exceeded the size limit of 1 GB instant! (but he doesn't based on storage views)

  Then I put the level to 10 GB makes no sense. It keeps me spamming all my virtual machines with snapshot size exceeded.

  This setting worked well with vcenter 5.0 because I upgraded to vcenter 5.1, this problem appeared. Note that I have 2 vcenters, two of them having the same problem.

  Please see the attached photos.

  VCenter version: 5.1 build: 880146 running on windows server.

  Would you kindly try to put the same trap and let me know if this is a bug or not?

  Thank you all happy new year

  It is a known issue with vCenter Server 5.1 (VM Snapshot size (GB) alarm incorrectly triggers on VMS with no snapshots (2037464)), which - according to http://www.vmware.com/support/vsphere5/doc/vsphere-vcenter-server-510b-release-notes.html - does not seem to have been resolved with the last 5. 1 b version.

• Space management and snapshot size

  Hi, guys.

  As I learned today deleting a snapshot can take fifteen or twenty minutes. From what I've read it can take much longer if he snapshot is extra-large.

  Here are my questions.

  When I have a virtual machine of the provisions, I could say that I am allocating 100 GB machine. The real op system can take 40 GB. Does this mean that I have 60 gigs of space left? If I take too many shots, saying, for example, 15 of them and each snapshot takes 4 gigs, I will crash the virtual machine because I filled my space? If so, do any kind of warning?

  My snapshots seem to be about 4 gigs each. What is 'normal' or not a size depend on the system operation and other factors?

  I don't see a way to browse my store of data and know how much free space is available for each virtual machine, if this notion is still relevant here. ..: -

  Thank you, as always.

  Hello.

  As I learned today deleting a snapshot can take fifteen or twenty minutes. From what I've read it can take much longer if he snapshot is extra-large.

  Yes, this depends on the number of snapshots and the size snapshots.

  When I have a virtual machine of the provisions, I could say that I am allocating 100 GB machine. The real op system can take 40 GB. Does this mean that I have 60 gigs of space left?

  If you use a provisioning, then yes the 60 GB of space left at the start would remain.  Over time, the amount of space consumed will probably increase because of the way that writing consumes space and cuts back by them.  You use VMFS or NFS to your data warehouse?

  If I take too many shots, saying, for example, 15 of them and each snapshot takes 4 gigs, I will crash the virtual machine because I filled my space? If so, do any kind of warning?

  Snapshots are stored on the VMFS or NFS volume and do not depend on virtual disk (VMDK) files.  You have to worry is in the data store.  This can happen, and it would not be a good thing.  If you use vCenter you can set an alert when data warehouses comes to some capacity.

  My snapshots seem to be about 4 gigs each. What is 'normal' or not a size depend on the system operation and other factors?

  Size depends entirely on the amount of entries past in the virtual machine.  The snapshot is basically a differencing disk, so all new entries is written in it.  Snapshots can reach the same size as the VMDK file.

  I don't see a way to browse my store of data and know how much free space is available for each virtual machine, if this notion is still relevant here.<>

  Check your data for the amount of space available warehouses.

  Good luck!

• Collection of information from snapshot size takes 10 + hours

  I stipped name most of the other information, so it is only by pulling the virtual machine, number of snapshots and the total size.  However it EAujourd takes 8 to 12 hours to complete.  Is it possible to speed it up?  Thank you.

  I forgot to tell you that.

  The script uses a c# structure that allows me to add a variable number of columns for the snapshots.

  But once this structure is loaded in your PS environment you can't change it anymore.

  Can you stop/start the PowerCLI or any environment PS prompt you run the script from?

• Report to the size of the list of snapshots that are used by a virtual machine

  I'm looking for to add to my report to the size of all the snapshots that are currently used by each virtual machine.  For example, I'm already reporting on space put into service and used space - but how much space are using snapshots?   Is there a way to get this data using powerCLI?

  Thank you!

  Get-Cluster-name NOMCLUSTER | Get - VM | Select

  Name, MemoryMB NumCpu, Description, PowerState, ProvisionedSpaceGB, UsedSpaceGB, Version, VMHost, ResourcePool,

  @{N = "HDsizeKB"; E={($_. Hard drives | Measure-Object-CapacityKB property-sum). Sum}} folder,.

  @{N = "Datastore"; E={($_ | Get - Datastore). Name}},@{N="#snapshots '; E={($_ | Get - Snapshot). County}},

  @{N = 'Name of the OS'; E={$_. Guest.OSFullName}} | Export-Csv "C:\report.csv" - NoTypeInformation

  The cmdlet Get-SNapshot in PowerCLI 4.1 returns an incorrect value. See the size snapshot by Dimitar and Vitali.

  And they display a script, called getsnapshotsize - 1.ps1 that returns the correct value.

  You can use this script to your script as follows:

  (1) download the script and save it in the directory where your other scripts

  (2) call the script of the post in your script and use the size of return value

  Something like that

  Get-Cluster -Name clustername | Get-VM | select Name,MemoryMB,NumCpu,Description,PowerState,ProvisionedSpaceGB,
       UsedSpaceGB,Version,VMHost,ResourcePool,
       @{N="HDsizeKB";E={($_.Harddisks | Measure-Object -Property CapacityKB -Sum).Sum}},Folder,

• No snapshots, but watch that I might have

  As you can see on my screenshots below, I have not instant, but the volume indicates that I have 300 GB +.

  I don't know if this happened after I installed the version 6.4.0 BETA 3, but it was the only change that I made recently.

  

  

  

  Snapshot size bug is fixed in version T-136 (Beta 4)

  It runs very smooth on my ReadyNAS 104.

• I - delta.vmdk files, non - .vmsn files. It is safe to delete all the snapshots in snapshot Manager?

  Hello

  Our VM froze because our ESXi data store is full. I deleted - .vmsn for the 1st file snapshot via CLI (using the "rm" command).

  VM is on thick disk and have 2 snapshots. so I still - flat.vmdk, - delta.vmdk. (for the two snapshots) and - .vmsn (only for the 2nd snapshot).

  wouldn't be all right if I delete all the snapshots in snapshot Manager? ATM, we don't have that 8 GB on the data store, and snapshot size is approximately 67GB

  Thank you

  Dan

  The lack of . VMSN file shouldn't cause problems because it is necessary in case you want to or need to go back to a snapshot. In all cases, with only 8 GB of free space on the disk, you can consider deleting the snapshot with the virtual machine being turned off. This avoids the need for disk space temporary additional database snapshots while / delta are merged into the base/flat disc.

• VM wants to drive consolidation, but no snapshots are listed in the Snapshot Manager

  After a replication failed with VEEAM, I get this on one of my virtual machines:

  "Configuration problems.

  Disks of virtual machines-building is necessary. »

  without having any snapshots indicate Manager snapshots.

  The name of the drive listed under 'change settings' does, that the disk is a snapshot, however.

  How to solve this problem properly?

  Best regards, Lars.

  The two option should work fine even when the virtual machine is running. According to the snapshot sizes, deleting it may take a while so please be patient.

  André

  PS: A thought if the Basic virtual disk is thin and put into operation, make sure that you have enough of free disk space on the data store before starting the deletion/consolidation!

• The list of all snapshots wth Orchestrator with

  Hello

  I'm doing a script to list all snapshots of a vcenter Orchestrator with javascript. It's easy with powershell, but we changed our vcenter for vcsa 5.5 windows so I can't use it.

  I would like to have the date of creation of snapshots, snapshot size and vm. I would like to have the output to a file to send it, or in html format.

  I have to say that I'm not good with orchestrator, this is a new product for me, and I know not how to send an e-mail and how to make a script of ' hello world! '

  Someone at - it a script like this?

  Thank you to

  Try this workflow attached... Recently, I helped someone with a similar request.

• What is the use of snapshots of consolidation?

  I've read up, but I'm still not really what is the usefulness of this feature.

  Please can someone enlighten me?

  Also please correct if my train of thoughs is wrong:

  i. instant aren't really backups

  II. the Snapshots are supposed to be taken so that the virtual machine can be recovered at this point in time (for example, before the Windows Update)

  III. snapshots are "integrated" with dare the virtual machine (via VMware Tools), which means that we can make the Brownie when virtual machines are on the rise.

  -Windows 2008?

  -Microsoft SQL?

  IV. Snapshots would take place outside the VMs

  -The data store should be much larger then the VMS (for example if the virtual machine is 200 GB, datastore shd be 300 GB to VMDK + Snapshots)

  -Snapshot sizes would grow as time passes (eg. instant 100 days ago risked increasing from 10 GB to 20 GB according to the changes made to the virtual machine)

  v. recommendations (by VM)

  -Do not to keep snapshots to extend the periods of time

  -Do not keep too many clichés

  -"consolidate" snapshots

  So, what is the difference between "Consolidate" and "Delete All"?

  I think you may have the wrong idea of the snapshot...

  I would like to use Windows update + service pack installation for example.

  VM with MS svr 2003 running... you can install SP1, and then test, can install updates to Windows, and then test.

  -snapshot 1 (sn1): Win2003 Updates & SP

  -Install of Win2003 SP1 (with reboot etc.)

  -snapshot 2 (sn2): Win 2003 SP1

  -Install Windows updates current on Win2003 SP1

  -snapshot 3 (sn3): Win 2003 SP1 with updates

  -svr stable for 5 days (eg. installing Acrobat reader, Microsoft office)

  So u shd have 3 pictures... who all "grows" that you test your DVS.

  But your VM will be 4 types of main file (with respect to this context)

  1. basis of files of the virtual machine (vmdk, vmx, memory of the computer virtual, swp files etc.)

  2 VM snapshot file

  3 VM snapshot files swp (swap is maybe not correct name... but I do think that the proper name)

  In terms of logic...

  -'sn1' is the basis of the snapshot

  -"sn2" is "sn1" + "data1."

  -"sn3" is "sn1" + "data1" + data2.

  "- VM1 is sn1' + 'data1' + data2 ' + data unnamed swap

  The 5th day of test, the virtual machine will have files for

  ' '- sn1', "sn2", "sn3", 'data1', 'base VM,' data2 ' and unnamed swap data that are generated during the 5 days of tests.

  Then from the right 'consolidation' will convert the name in "data3" swap so that

  -'sn1' is the snapshot of base + 'data3 '.

  -"sn2' is 'sn1' + 'data1', 'data3 '.

  -"sn3" is 'sn1' + 'data1' data2' + 'data3 '.

  "- VM1 is sn1' + 'data1' + data2 ' + 'data3 '.

  In a way layman... Virtual machines with snapshot are VMs who have ΘtΘ divisΘs into multiple files.

  "" When you remove stereotypes (please do not try everything remove), what you do is merge sn1 "+"data1"+ data2 ' + data not named swap or 'data3' in a virtual machine.

  Sorry... I forgot to add... Please do not receive or keep snapshots VMware for long periods of time.

  The snapshots are not backup. They can line up while you have yourself photographed... soon...

• How to take snapshots on a global scale

  We use virtual disks supplied thickness in VMware but use thin volumes put into service on our SAN (known as thin thickness).

  We back up our virtual machines using Backup Exec, which creates a snapshot for VMware backup of the snapshot and then removes it.

  When if failed backups can leave the snapshot behind which uses more disk space on the SAN until we notice and delete it.

  Thin provisioned SAN volumes cannot grow, not shrink, then the extra space that has been used so that grew the snapshot is now wasted in the SAN.

  It is therefore an easy way to monitor snapshots without entering the Snapshot Manager for each virtual machine, just a place that would be would be list of all pictures in our cluster.

  Any ideas?

  Thank you

  You can create an alarm in the VC, there is a default a VM Snapshot size available (GB) who customize to the size warnings and the alert message.

  Or use powercli to run a script every day to send a list or instant operation, there are a few scripts autour already that you can use (Chris Uys made one).

• Overview in vSphere Web Client?

  Hi community

  In vSphere Client c# , I had the chance to see an overview of all virtual machines and their snapshot spaces: home - inventory - warehouses and store data from cluster - storage tab views.

  By selecting my data center on the left, I had a glimpse of all the VMs on a data center and size of snapshot (on all data warehouses). See my attached screenshot.

  I just upgraded my vCenter to 6.0U2, so I did not tab views storage more.

  Does anyone know how to proceed with the Web Client vSphere? I don't want to check every vm or each data store but would like to have a similar overview of instant spaces of all the virtual machines on all data warehouses.

  Best regards

  Roland

  Version 6 does not offer this view more, see this KB article: VMware KB: The Storage Monitoring Service plug-in installs in VMware vCenter Server 6.0

  In VMware vCenter Server 6.0:

  • The selection of storage reports tab monitor an object is no longer available in the Web Client vSphere 6.0.
  • Tab views storage is no longer available in the vSphere Client 6.0.

  As I said before, you have the possibility to use RVTools or something like PowerCLI and vRealize Operations Manager, see this thread another talking about the same thing: the storage vsphere6 reports

  We were using display of storage reports to audit for forgotten shots. So far, there are some alternatives to see the snapshot size

  Use of Ops 1 Manager) and a heatmap personalized, note the Foundation (for some free version) does not have the feature. As we use Foundation, it is not an option.

  (2) RVTools - GUI based (easier for some) but pretty basic

  (3) PowerCLI - yup, get used to it. (get - vm | get-snapshot |) FT VM, SizeGB, created, name, Description)

• 48 hours instant historical report

  I'm looking for a script that can give a report of all the clichés that have been created and deleted in the last 48 hours on all data warehouses. Basiclly I want to do is set up the timeline of our backups when snapshots are created on each virtual machine and what data store the snapshot has been created on the size of the snapshot.  The question we have is that our data warehouses are roughly on provissioned (Installer before starting here) and not budget for additional storage at this time.  We had problem with stores fill during backups because data snapshots.  I want to change the location where the snapshots are created to a different dedicated LUN to the Virtual Machine folder by default.  I want to have an idea of when the snapshots are created, the snapshot size, when removed, in a 48-hour window.

  Any ideas on how this can be done?

  I can watch the backup program and see when the virtual machine started the backup process, but he didn't tell me what data store, the virtual machine is on and what other VM is currently underway in the same database.  Also storage DRS can move VM around and now cause problems with e/s when multiple snapshots are created on the same logical unit number at the same time.

  I'm just trying to get a better idea and a good way to create a Visual report to view my managers why databases are fill due to backups.

  Thank you

  You could do something like that

  $taskNames = "CreateSnapshot_Task", "RemoveSnapshot_task".

  Get-VIEvent-beginning (Get-Date). AddDays(-2) - MaxSamples ([int]: MaxValue) |

  where {$_-is [VMware.Vim.TaskEvent] - and $taskNames - contains $_.Info.Name} |

  Tri-objet-property Createduserid |

  Select Createduserid, username.

  @{N = "VM"; E={$_. UMM name}},

  @{N = "Datastore"; E = {(Get-View-Id $_.)} Vm.Vm - property 'Config.Files.SnapshotDirectory'). Config.Files.SnapshotDirectory}},

  @{N = ' task'; E={$_. FullFormattedMessage}}

  The size of the snapshot is problematic, since the snapshot is already removed when you run the report.

  If the snapshot still exists, you can calculate the total size of the snapshot.

  See for example my UML diagram your VM snapshots and the vdisks, you can use the same logic to get the total size of the last snapshot.

• The instant profile questions

  I read the article in the knowledge base on the structure of files and folders that are created when the snapshot is taken. I looked at my data store and I did not ' see the file with 00003.vdmk. I didn't ' see the file with the name of delta on the name of the file. Is there a problem because this file is not there?

  Also is there a formula that would allow me to calculate how long it would incorporate the original virtual machine snapshot?

  Thank you for your help

  Edsel

  The numbers used for snapshots not necessarily be in the same sequence as snapshots. With the numbers in your case, it seems that 8 snapshots have been created, and then some of them have been deleted. If you now create another cliché, it would most likely get 000003 in his name, because it is then next free number.

  With the current snapshot sizes, remove them (using "remove all") may require between 1 and 2 hours on a system with a flow rate of ~ 10 MB/s.
