• Get daily usage of memory and CPU VMs

  Good morning guys,

  Will be possible to do?, all that I need is to get all our virtual machines the CPu and the memory (percent) usage for the day elapsed (within 24 hours) for each virtual machine and save it in one. CSV file, also send me an email telling me that vCPU and daily usage report memory was created, here is what will be great to have:

  CPU and memory daily report:

  The virtual computer name . vCPUs Assigned | Last day, use of the CPU Max . Last day, the CPU min | Average CPU utilization last day | Men assigned . Max men use last day | Use of men min last day | Average use of men last day |

  Appreciate any help.

  Thanks in advance.

  Try something like this

  $report = @()
  $metrics = "cpu.usage.average","mem.active.average"
  $vms = Get-Vm | where {$_.PowerState -eq "PoweredOn"}
  $start = (get-date).AddDays(-1)

• When to start CPU contention?

  I have a core eight ESX 3.5.0 server running about 25 VM.

  Usually, the server runs with 40% CPU usage.

  At what time would you expect vying for CPU come into play?

  What is the best way to control the CPU contention?

  Thank you

  Steve

  Your understanding of contention made CPU fault... it is NOT a direct consequence of vSMP exclusively.

  If you load 100 100% active single CPU VMs on a host of 8 cores, you would end up with submission and high when they're ready, no matter if made them vSMP or not.  Certainly, vSMP increases significantly the liklihood of restraint and high when they're ready, but it is not the only (or even primary) contributor.

  To the OP - theres no individual number because it depends on your vCPU mixture and the activity of the virtual machines themselves.  For OUR environment, we try to keep it under 70%, but this is only a valid number for OUR CA.  Your, in all liklihood, will be different.

• Fake call Tx detected with 160 seconds timeout

  I just upgraded ESXi hosts to 6 5.5U2 8. 0 b (2809209).  The first host I have improved (a Dell R910) is fine for about a week and then died in the middle of the night Sunday night.  Came to him hung up, couldn't SSH to it, does not respond on the console and was shown as disconnected in vCenter, all virtual machines on it had HA'ed to other hosts.  Should be able to turn off that through iDrac and he came fine.  The syslog feature stopped 9 minutes before the events in vCenter showing he's going down, so I couldn't check the newspaper to see what happened before he went down.  Writing chalked up an anomaly and put back into production.  Less than 24 hours later, woke to pages of our monitoring system of virtual machines on the same host.  These virtual machines are inaccessible.  The host was always sensitive and marked as upward in vCenter.  Cannot open consoles for any of the virtual machines on this host.  Was able to SSH in the host and it was in the vmkernel.log:

  These repeated again and again many times per second.  The host locked again shortly after and had to be restarted to force the VMs system HA to other hosts.

  The vmnic4 and vmnic5 are ports on the same Intel NETWORK adapter X 520-2 (two ports), Intel, not the re-brand of Dell version version.  We have two of these network adapters in each host with the ports of the other card of the NETWORK being vmnic6 and vmnic7.  vmnic4 and vmnic6 go to our network local, vmnic5 and 7 go to our iSCSI network.  These cards use the IGB driver (ethtool reports 3.21.6iov * last * with firmware version 0x61c10001).  TSO and LRO are off due to problems that we already had.  I spent yesterday upgrading all the firmware on the host of problem but the Intel X 520 - 2 does not appear to be newer firmware that I can find, even if Dell seems to have a version for it which does not apply to these network cards Intel version.

  The host of problem is currently in production with a very low charge on it for more than 24 hours so far and I am increasing the load on a regular basis to see if it eventually bombs again.

  Googling "Fake Tx crash detected" results in a lot of older hits, mostly from the Linux IGB problems associated with pilots.  Nothing to really related to VMware.  And nothing that seems relevant.

  Any ideas?  Find it me hard to believe that the NIC itself suddenly has gone wrong that this host has been with us for years without problems until we went to 6. 0b.  I have an another R910 which was bought at the same time that I'm tired of the upgrade that I can't have two hosts having problems it would cause problems of capacity within our cluster.

  Say that there is no work around and the only solution was to go down to 5.5U2 when I opened a SR with VMware, I discovered other ways there is a workaround script that seems to change the management of interruptions of CPU from automatic to manual, which is supposed to be the cause of this problem.  Why VMware is distributing this script to some people and not others that I don't know, I hope it was just the tech who worked my case not having is no knowledge of the script of the workaround at the time said.

  EDIT: I should add that since the purpose of this script to our guests, we have not seen the problem still happen when I had three accidents in the first week.  /knockonwood

• SatPro A60 can hardly operate at 2.8 GHz since problem of thermal regulation

  Hey guys, a nightmare for A60, its CPU clock can hardly run at 2800 MHz, it is supposed, since 75 of the A60? Thermal regulation time is too easy to access.

  Using the processor RightMard and Mobilemeter clock utilities, I found the temprature entry A60 to thermal regulation 75? When this temperature is reached, cpu clock slow down up to 1500 MHz (you can't see it using the normal test program, because Throttling is like cheating... that is to say force CPU to stop for some time in order to avoid overheating), and when temperatures rise less than 70?, he will return to 2800 MHz. Another delay: the auto-off temperature is 85? for A60.

  Although the temperature which got the Mobilemeter is the sink, not the CPU core temperature, it seems that oshiba made this 75? Date limit too low (default time of Intel is probably about 90?). In addition, with evil designed sink heater, the temperature remained generally above 70-80? with room temperature 15? and only some word processing or navigation base and also with the machine almost free of dust. All this means that the laptop can hardly run at 2.8 GHz. You could never have this speed in any graphical game.

  The real clock must be test using RightMark clock, it allows to test if the CPU is forced to stop frequently due to thermal regulation. Everyone wants to do this experience can download these two free software of:
  RMC(177Kb):
  http://CPU.RightMark.org/download/rmclock_18_bin.rar
  MobileMeter(40Kb):
  http://www.geocities.co.jp/SiliconValley-Oakland/8259/release/0310/mm0310.zip

  with SuperPI, who can make as high CPU temperature as you want opening it serval times at the same time
  http://ftp15.ENET.com.CN:88/pub/system/sysanaly/SuperPi-8.zip

  Finally, my original idea to write about it here is not only to tell a truth, but also I want that people of Toshiba could do something on this issue, or do an updated bios updated to allow to off the thermal regulation, or make the deadline for her superior to only 75? ,
  as you have about bios satellite 1805 last updated:

  Version 2.10 24/09/2002
  A change has been made to allow only BIOS enable and disable the CPU limitation during the operation of Windows 98SE.

  Give the original CPU speed, because that's the only reason I and a few other people chose this machine.

  Hi Al

  Well, I put t know if you have experience in the technology of the laptop but heat is a known issue on all laptops. It s a fact that all the parts (Cpu, graphics card, etc.) in the unit produce a lot of heat and it s very difficult to cool these rooms because there is no place. You can't compare the computer laptop and desktop PC!

  In addition, to protect against overheating of the CPU has an internal temperature sensor. (You know that) If the temperature of computer s reaches a certain level, the cooling fan is turned on or processing speed is lowered. You can choose to control the temperature of the CPU by the setting of the fan first, then if necessary, reduce the speed of the CPU.
  Alternatively, by lowering the speed of the CPU first, then if necessary, turn the fan. You can use the element of the standard tab cooling method in Toshiba Power Saver.

  Here are the features:
  Maximum performance: Turn on fan first, and then if necessary decreases the speed of the CPU processing.
  Performance: Use a combination of fan and a decline in the processing speed of the CPU.
  Optimized battery: Lowers the speed of the CPU first, then if necessary turns on the fan.

  In addition if the temperature of the CPU reaches an unacceptable level with two parameters, the system stops automatically to avoid any damage.

  Hopefully this description can explain this problem.

  Best regards

• Satellite Pro P100 - WinDVD stutters during playback

  Satellite toshiba windvd Pro100 stutters during playback of dvd movies - worse yet, when you use windows Vista media player - can help you solve?

  Hello

  If Norton antivir is running, try to disable all functions. My experience is that permanent HDD scan can force CPU for greater use and because of this DVD movie stutters all playing.

• Stuttering DVD with Satellite L series

  DVD played fine for a year, but last night, they began to stutter, audio and video.

  I have compacted the HD and released as much memory as possible by disabling the AV etc, but this was not necessary before.

  Any suggestions as to what happened and how I can correct are very popular.

  Alex

  Hello

  Please check all the processes running, particularly activities of antivir. For the most part a background activity force CPU to run faster. This may be responsible for stuttering when watching films on DVD or listen to music CDs.

• Satellite P100-160: cooling fan comes loudly for 1-2 seconds every 30 seconds

  I have Vista and I tried everything.
  I set the thermal control mode in the BIOS to "Silent" (although sometimes I look in the BIOS and it is up to the performance). I have disabled Aero, changed the minimum and maximum processor speed etc..

  The irregular, loud fan noise leads me into the wall! I'd rather work permamnently at volume slightly harder than that! The laptop is great, but if someone said "I'll give you a full refund" I would like a shot - only on this noisy fan irritating each ch. 30 seconds!
  Can anyone help? I suspect not - I suspect Toshiba needs to work on its drivers and maybe a BIOS update. I kind of feel that I am at the edge "bleeding" here with this purchase. I have other problems too that I'll post separately.

  Hi David

  I'm sure that any comment as if it was normal will be good enough for you, but there is really not much to do. You can try to play with the power settings and see if something will be better.

  Two weeks ago, I did some experiments with P100 and I installed my Vista with the necessary drivers and tools only. I was positive surprised how Vista works now. If possible, remove all the stuff that you don't need. The fact is that much preinstalled stuff running in the background and force CPU to work under pressure. I really don't see another solution at the moment.

  In my opinion it has nothing to do with the drivers, but perhaps with BIOS. We'll see if Toshiba will offer soon new updates to the BIOS.

• Equium A200 - 1VO hangs intermittently

  I bought a brand-new Equium A200 - 1VO and it crashes intermittently. When it crashes near the top, nothing does. Laptop must be switched off / get it on.

  No one knows why this happens? Nobody knows how to solve this problem permanently? Your help will be appreciated.

  Hello

  You must understand that no one can give you an answer why this happens. Nobody we exact configuration for laptop and software pre-installed. I imagine that some background activity forced CPU to 100% of the blocks of its use and laptop.

  Try to open the Task Manager and try to find out what process force CPU 100% usage.

  I noticed the similar problem by running IE7 on my Satellite P200.

• Storage strategies, SSD?

  First time with VSANS

  If I have 6 guests with a mixture of SSD and the rotating discs, is it possible to force specific VMs to use the SSD or do I need to create a separate VSANS cluster?

  6 guests:

  Host 1 - 3 has 1 SSD and 8 turning each

  Home 4 - 6 has all SSD

  Thank you

  There is a way to put a "Flash read the booking cache" on a VSAN hybrid both a VMDK can essentially 'live' in the level of caching in a hybrid configuration.

  Honestly our caching isn't a simple FIFO buffer (we are working on publishing a good page 8 read on this subject) so unless your having problems and support is to steer you reserve the cache, I would trust CRA and other systems that we use to be smart enough to do the job.

  FYI: the default policy is mirror once, Ray zero, no strength of commissioning, no reservation space.

  You can have lots of fun with the policies, but I'm curious to know what is your use cases?

• Fusion 8 Pro (Mac) / vCPUs how? (3.5 GHz Intel Core i5, ultimo 2014)

  Hello

  I use the trial version of VMware Fusion 8 Pro on an iMac.

  Mentioned the title CPU has 4 cores and 4 wires.

  VCPUs how I could create for my VM runs in Fusion 8 Pro.

  Kind regards

  Roland

  Hello

  Really just try and see how far you get as processors behave differently.

  With virtual hardware 11, you are limited to 16 vCPUs in your guest OS.

  I'm not sure what the limit is for vHW12 (Fusion 8), but I do not have to start a little lower and intensify If you need more.

  Your guests will share CPU resources between them, this isn't like 4 nested dual CPU VMs need 8 vCPUs in your virtual ESXi.

• vCPU Allocation

  Hey guys,.

  I fell on the first number of vCPU use... I didn't know that there so far. I guess that you can run 25 by heart physical vCPU on a server? I created all of my models with 2 Sockets and 2 hearts, giving total 4 cpu VMs, but let me just run about 50 virtual machines... I so went back in my models, cloned, deleted the old, changed the clone of 1 Plug and 1 core and booted up outside Director. VM appeared to run very well, performance and all.

  I re-imported the model to the Director, then deployed a virtual machine of this model with the CPUs has changed... the virtual machine runs very slow (it takes about 5 minutes to just log) and I can't really do anything else as it's the jump frames look. I looked into the Task Manager and CPU usage is at 100% when I do something as simple as opening internet explore. I then did the same procedure as above, this time making 1 Plug and 2 carrots, it helped somewhat reduce the CPU usage averaged about 50 percent.

  What I don't understand is why outside Director, virtual machine works absolutely well with little or no overhead for the use of the processor, but in the realization, it's awful. Am I set something wrong or is this something with the 50 VM Director already use all 4 vCPUs already? I am trying to run the maximum amount of virtual machines that I can, but I don't know how to to this topic as it seems you need to have all kinds of restrictions for consumption in place. Thanks for any idea.

  -Mike

  By default, VCD allocates only 5% of a physical processor as a limit to a given virtual machine (see: http://www.yellow-bricks.com/2010/09/22/vcd-allocation-models/) which is a performance very very little.

  That to something more reasonable.

• I really do this now, but...

  I'm trying to write a simple script to write data.  I normally don't use Export-Csv, but I'm for this report.  I went back and discover how Export-Csv can output data as [System.Object] and [System.String], depending on how Powershell sees the data.  The section of IPaddres, I was getting and then I made the adjustment for out of the way of writing, but for hard drive data, I can't make it work.

  Given that some virtual machines have several readers, I see that Powershell shows he has a FlatHardDiskImpl, but I don't know how to get to the exit properly in the csv file.  I tried many things for the hard drive section: subexpression, Select-Object, Array @ (), but I cannot get export-csv to show the two discs.  I really thought I'd get this now, but there is still so much more to learn.  Here's the script.

  $AllReport = @)
  Get - vm | {Foreach}
  $VMS = $_
  $Report = "" | Select VMName IPaddress, domain name FULL, OStype, "Memory (GB) ', CPU 'HD (GB)'
  $Report.VMname = $vms.name
  $Report.IPaddress = $vms.guest | Foreach {write $_.} Ip_address}
  $Report.FQDN = $VMS.guest.HostName
  $Report.OStype = $VMS. Guest.OSFullname
  $Report. 'Memory (GB)' = $VMS. MemoryMB / 1024
  $Report.CPU = $VMS. NumCPU
  $Report. 'HD (GB)' = $VMS. Hard drives | Select CapacityKB | Foreach {write ($_.)} (CapacityKB/1Mo)} impossible #I that it works correctly
  #Write $Report
  $Allreport += $Report
  }
  $AllReport | Export-Csv - NoTypeInformation C:\file.csv
  II C:\File.csv

  Hello, : DZ1-.

  If you are looking for a list of the disc formats in the property "HD (GB)" of the $Report object, you can change the line you mention that you are unable to work properly to something like:

  ...$Report.'HD(GB)' = ($VMS.HardDisks | %{[Math]::Round($_.CapacityKB/1MB,1)}) -join ","...
  

  You should get the VM hard drive format given in this property.

  And, later, you talk about the New-Object cmdlet.  Here is an example usage of this cmdlet in your script:

  &{Get-VM | Foreach {    $vm = $_    New-Object -TypeName PSObject -Property @{        VMname = $vm.name        IPs = ($vm.guest | %{$_.IPaddress}) -join ","        FQDN = $vm.guest.HostName        OStype = $vm.Guest.OSFullname        "Memory(GB)" = $vm.MemoryMB / 1KB        CPU = $vm.NumCPU        "HDs(GB)" = ($vm | Get-HardDisk | %{[Math]::Round($_.CapacityKB/1MB,1)}) -join ","    } ## end new-object}} | Export-Csv -NoTypeInformation -UseCulture C:\file.csvii C:\file.csv
  

  Using New-Object, you don't need to store things, you don't need to add them to a table, then you can help reduce the memory usage in your scripts (not that you run your client machine out of memory, but you can cause script errors to System.OutOfMemoryException exception).  And you can see how it's a little cleaner with less repetitive typing.  I also used the cmdlet Get-hard drive here, as the. Drives property is obsolete.

  How do these examples for you?

• How to change the number of processors / cores

  I have virtual machines that I have to move periodically between 3 computers main host that I use:

  1 Intel Core 2 Quad CPU with Windows 7 Home Premium 64 - bit - 1 processor with 4 cores

  2 Intel Core i7-2630QM CPU with Windows 7 Home Premium 64 bit - 1 processor with 4 cores

  3 Intel Core 2 Duo T7700 CPU VT with Windows XP 64 bits - 1 processor with 2 hearts

  Hosts running VMWare workstation 7.

  Most of my virtual machines running XP 32 bit and have been initially created for my 3 platform.

  When I move my machines between computers I see that the parameters of the Virtual Machine for my change of processor in (for me)
  in unpredictable ways. Sometimes it shows 1 processor and gives me a choice of up to 4 cores.
  in other cases (always on a 4 base platform) 1 single processor with 1 core, in other cases, with 1 core 2 processors.

  In most cases, my freedom of choice is limited, because the selection of the number of cores is grayed out.

  When I try to make changes by editing the vmx file, I find them ineffective (no change).

  The other problem I think is that my VMs run VERY SLOWLY on my i7 with 8 GB platform!
  I have no idea if this is related to the improper setting of the number of processores / cores (I'm not able to define
  1-4-hearts and spin with settingsd 1.1 instead).

  Could someone please help me understand how:

  1. check / change the number of processors / threads on an existing virtual machine.

  2. how to set properly for an i7 processor

  Thanks in advance,

  Andrew

  1. providers that create virtual machines are in a race - they assume that customers use this version which proposes to use the virtual processors more ;-)
  For some workloads inside a virtual machine - say Oracle or other database and applications servers such that it is sometimes really good idea to use more than one virtual processor

  2. virtual machines to scale differently with more CPU than the real computers.
  Virtual machines are for host applications.
  This means that the host schedules the time CPU to each virtual machine.
  If you follow this thought that you will see that a virtual machine that uses one virtual processor has a greater chance to run then a VM with 2 virtual processors.
  A VM with 4 cores running on a host with 4 cores will spend a lot of wait time - it may work only when the host reports the application of Workstation 4 hearts are available.

  A virtual machine with only 1 vCPU will probably be able to run all the time without any waiting time.
  This is why usually with a single CPU VMs feel better to the needs of the user.

  This translates into the best practical advice: assign a CPU unless you really notice you need more.

  3. probably, you try to change the values, while the virtual machine is suspended?

  4.
  numvcpus = '8 '.
  cpuid.coresPerSocket = "4".

  We hear two processors with 4 cores of each

  numvcpus = "4".
  cpuid.coresPerSocket = "4".

  means a processors with 4 cores

  numvcpus = '2 '.
  cpuid.coresPerSocket = '1 '.

  We hear two processors with a carrot

  No effect? n ' mind that not all clients can use 2 or more processors
  For example, XP is limited in this respect.
  Some guests may also not change the number of CPUS after what they have been installed
