Get-Cluster execution memory and cpu details

I am writing a script to generate graphs based on average use memory and cpu during the previous month, but I'm doing it for each cluster itself without explicitly naming them. The graphic bit side (I use mschart or googlechart for this) I just need to get the actual statistics and it's the bit that I have a problem with because everything I see with my research pulls the individual information of the VMs or the hosts in the cluster.

I am looking for two values in each case - the name of the cluster and average use. But the use of the average for the overall Group and not the indivdual VMs.

I was watching this:

script of PowerCLI to capture cpu usage statistics & mem

But that you use hosts.

I have attached a picture of something that I'm looking, red line on average in percentage and the blue line on average in megabytes. It has been exported from the vcenter however. I'm just trying to save time.

Thanks in advance

For a data point average per day, you can simply add -interval 86400 education Get-Stat:

Get-Stat - entity (Get-Cluster Cluster) - Stat $metrics - start $start - finishing $finish - interval 86400
Instance of MetricId Timestamp value unit
--------                ---------                          ----- ----     --------
CPU.usagemhz.Average 14.05.2014 02:00 MHz 4298
CPU.usagemhz.Average 13.05.2014 02:00 MHz 4109
CPU.usagemhz.Average 12.05.2014 02:00 MHz 4163
CPU.usage.Average 14.05.2014 02:00 10,74% *.
CPU.usage.Average 13.05.2014 02:00 10,27% *.
CPU.usage.Average 12.05.2014 02:00 10,41% *.

Note that it may not include the values of the last day, since the rollup database for daily statistics task has not yet executed.

  • ESXi 5.1 - Exchange 2007 - file Page memory and CPU allocation

    I'm currently migrating a class Cluster CSC Exchange 2007 running on vmware on windows 2008, 2003.  It is also a SCC Cluster.  I followed all of the vmware and MS best practices, but not sure of one thing IM is the size of memory and CPU allocation page/swap file.  I have 5 Esxi hosts and each is running only Exchange 2007 comments according to vmware and MS recommendations when you use the Clustering of CSC.

    Each host has 2 CPUs to 6 cores per processor and 48 gb of Ram and that each host will have only a guest, would like to send it to the guest.  I read somewhere that it is recommended this page exchange 2007 memory size + 10 mb file.  Do I really need to get the page to the size of the file?  250 GB of disk space is a lot for swap files! IM also not sure what to set the allocation processor too.  If someone can point me in the right direction, I would be grateful.

    Thank you

    Hi dlargeit,

    First of all, off - welcome to the VMTN forums!

    I'm with Josh26 I've ever seen any recommendations indicating that when a CCS cluster virtualization virtual machine by host is taken in charge. It is recommended to keep only a single node SCC by host (which is true for all virtual clusters or technologies like Exchange CSC/CCR/DAG), but there is nothing specific regarding the keep only a single virtual machine by host.

    On the file page, you are actually right on that.  For Exchange 2007, the paging file must be on the amount of memory configured as well as 10 MB to account for overhead costs of the kernel.  It is recommended by Microsoft and it is planned to provide enough space page Exchange should exchange more provide the necessary overhead if meet you a server failure and need to create a complete memory dump.

    You can find this recommendation here: http://technet.microsoft.com/library/aa996719 (EXCHG.80) .aspx

    In terms of CPU allocation, which should really be made according to your individual needs rather than just give all the resources the VM on the ESXi host.  Microsoft lists the maximum recommended for processor resources (Planning Processor Configurations: Exchange 2007 help) and it says that 12 hearts is the maximum for mailbox or Hub Transport box.  Is your really big enough environment need a lot of CPU resources?  Why not start small and increase it if necessary?

    You are in control of your own destiny in some of these configurations.  If you know the recommended page file size is 10 MB of RAM +, do not give the server more RAM is really needed, or you will have to pay for it in the consumed disk space to host the pagefile.  See the guide to memory resources (Planning Memory Configurations: Exchange 2007 help) to understand the maximum rates of memory for Exchange.  You will see that the maximum memory is 32GB, so there are very few reasons to assign all 48GB of RAM on your server, if it can even use.

    In short, the size of the server based on the real needs and I am confident, that you will have a virtualized Exchange system that performs as well as physical.

  • Flash Player 17.0.0.134 high memory and CPU

    Hello

    I can't find any information or solutions to this. From the 17.0.0.134 updated Flash version, it uses a ton of memory and cpu high. I've updated everything (windows, browsers, plug-ins, video... etc) I am on Windows using Firefox 36.0.4(up-dated hier de.0.3) 8.1 and it continues to sky rocket, and then everything slows down and tell me the shockwave plugin broke down and I need to close. In addition, I continue to receive messages from my Norton on the high use of the disc of the flash player: (PLEASE)... can someone help me or at least tell what other people have the same problem.

    Thank you very much!

    Yes, I'm not surprised by the memory.  Farmville may have earned of objects loaded, which gets intensive memory, and then we do a lot of caching and optimization on top of it.  The CPU usage is higher than I'd like, but there is so much crazy stuff goes under the hood of these kinds of games.  Zynga is actually in front of the team of Flash Player in San Francisco, so we spent a lot of time to work with them to build the profilers and adjust their games.

    Honestly, you will get probably better performance in IE - there was a lot of performance tuning for Win8 spent energy, and it does not suffer from either architectural deficiencies in the implementation of Firefox this impact, or performance of the OpenGL performance issue that affects the PPAPI Flash Player at the moment.  We are actively working on both of these problems, so it is hopefully a temporary situation, but two corrections are negligible.

    The ActiveX control also gets a lot of latest Windows compiler optimizations that we use for the Chrome or the plug-in on Firefox NPAPI still.  We will eventually migrate to the latest compilers of Windows for everything, but it's a lot of work.  Switching compilers seems easy, but it's always a very difficult effort when you have a million line code base and more.  I don't think that what you see, it's quite unreasonable as it is really ambitious content, but you will probably get a better experience of IE on the desktop with Stage3D mode such things.

  • Allocation of memory and CPU

    Guys,

    My question may sound trivial, but I need it to be clear.
    If I allocate a certain amount of RAM and CPU (without reservation) on some VMS, if virtual machines are not fully allocated amount, is used by other virtual machines.
    I am asking that more I VCOPs reports with a lot of oversized VMs and I also I know I must take measures to reduce the overhead of each virtual machine, I need to know if the memory and CPU are shared dynamically in case of needs of other virtual machines.

    Thanks in advance.

    Daniele

    Short answer Yes, if no reservation is defined, resources are allocated dynamically.  In case of contention, actions values will be used for the allocation of resources.  Virtual machines with lots of unused memory are taxed (income tax slowed) and claimed in a balloon.  The important thing is to know what the VM workload is running, and if VMs are memory aid for the contents of the cache, it is to say sql or exchange and these may consider oversized VMs.  Monitor the virtual machine during the period during the normal business cycle and the size of your virtual machines accordingly.

  • Reservations of memory and CPU

    Simple question please: a virtual machine must be powered turn off/on when implementing a reserve of memory and cpu? I know kernel certainly used swap file automatically disappear when the virtual machine is running and a reserve of memory - at least I do not.

  • HP 550: updated hp 550 memory and cpu with the unconventional settings. is not ideal, but not other choice

    HI guys, I hope you can help or at least give a point in the right direction. I am a freelance photographer with a large part of the suite creative Adobe CS6. After a disaster of a week, I came home to find the motherboard on my editing station is fried somehow. I don't know what happened though I wouldn't put past my inattention of roommates.
    I'm desperate. I have to finish my current job until I'm able to afford to buy a replacement. So I have to rely on stop-gap measures, in desperation to finish my project, that are less than ideal, but so far are doing better than I'd hoped.
    Im a photographer, Capture One, Adobe Photoshop Lightroom, Adobe Photoshop and Premiere Pro are the go for workaholic applications that I need to work. without them I have no income. in order to have this machine run these applications,
    the machine I have left is an old hp 550 that was gathering dust in the closet. It was built for 32 bit Win XP and in no case is designed to run adobe products food pork I use, particularly of Lightroom.
    Unfortunately PS with Lightroom and first are 64-bit programs and LR and first are hyper threaded. so I did some research and with the help of the list of the utility windows 7 Advisor to upgrade instructions, I was able to get windows 7 Pro 64-bit to install and run.

    I know that this is not the ideal machine or the situation, but for a few weeks, I need to make it work.

    I really just 2 simple questions. First of all, I went to the HP technical support. but they were not useful. as the guarantee of the laptop are long gone, they would be not even polite and basically told me to shove off. Then on another forum, I called back and comes with a knowledge it all who constantly insisted on the fact that there was no way no how this pc could run 64 bit win 7, which i thought what am I seeing things? It works very well for 3 months. So I decided to come to you. your forums were useful on many occasions.

    Basically, I need this machine to run these programs during the next month or two, until I can buy a new machine.

    essentially, what I want to know, it's the motherboard support an upgrade of the processor? and if anything goes, what do you suggest as a substitute, given my needs? The Core 2 duo is the bare minimum of what I can limp with like photo/video rendering times are excessively slow.

    then I was talking to the support staff essential tech upgraded memory. and possibly set the bios to force to run 8 gigs of ram. They said that they have cold cannot find any version of bios that would make that possible, but only by forcing already run 64 bit, which has already allowed the pc to use the full 4 GB of ram, which was impossible in the 32-bit format. He suggested that I buy 2 4 gig modules such as 4 GB DDR2 PC2-5300 unbuffered NON - ECC, 1.8V 512Meg x 64 which can be seen at http://www.crucial.com/usa/en/memory/ct51264ac667 and try to install the full 8 concerts and see what would happen, saying that he had a feeling that I might get lucky. his logic is that the 64-bit system already open the ram limits and who knows, you can't make an omelet without cracking of eggshells! It seemed very optimistic. So, what do you think? It seems likely you because I love to work. or do you think the guy was a quack? and this whole endeaver is a waste of time and money?

    also, any other suggestions on how to time this month long storm that do not involve suggestions of buying new machines would be appreciated!

  • Windows.exe gobbling up memory and CPU often CPU ranges between 50 and 100%.

    Hello

    My PC recently turned very, very slowly and often unresponsive.  When I bring up the Task Manager, on the processes tab, I see that Windows.exe uses as much as 1 million K of memory and often the CPU ranges between 50 and 100%.  What is happening while no application works.  I have also noticed that in the Task Manager, there are two processes with the name of the image of windows.exe and consuming all the power and memory has no user name.  When I try to end the process on this one it still won't let me and a message appears saying that I don't have permission to do this, or something to that effect.  I am however able to stop other processes including the windows.exe with my username process.  The cases where it allows me to stop the process, performance improves, but given a little time, again with nothing running, it starts again. Thinking it was a virus, I missed the live update on Norton and performed a full scan, but nothing found.   I also tried Windows defender, but in vain.  Any help on this problem is greatly appreciated.

  • Shares of memory and CPU

    Hello everyone,

    I was wondering how actually work actions. Given that the CPU shares these MHz influence how much will be the virtual machine when hardship and access to the virtual machine at the same time the pCPUs or actions also affect the time a virtual machine to use the pCPUs to keep a VM will spend more time the execution of the instructions?

    For the record, actions, when the host has a lack of RAM, the virtual machine will receive an amount of RAM based on the actions and if it is not enough for the hot air balloon of COS and swap will take place?

    Is this correct?

    Thank you

    Dan

    the Scheduler is called vmkernel. VMkernel CPU relocates the CPU every 20ms to balance the load and serve until new instruction time slices (based on all the actions and reserves) for each workload. If the CPU is not heavily used, everyone gets the instruction time when they need it.

    for the record, based on the actions that define the priority memory ballooning will activate to provide real memory for those who need more. just as in the case of memory should be enough memory it is memory virtual swap ESX follow always pagefile in windows OS.

  • Compaq 500 b memory and CPU compatibility problem

    I have a Compaq 500 b MT, that came from the factory with 1 GB of RAM and a processor Intel Celeron E3200 CPU.  I upgraded my memory to two sticks of 2 GB Kingston DDR3 1600 RAM, which worked perfectly for a while.  I then upgraded my CPU to an Intel Pentium E6500 CPU processor (supported), and when the start he gave me a code beep RAM (1 short, 1 long, 3 second pause) error.  I bought 2 sticks of memory PNY thinking I have fried my other sticks.  Same beep code.

    To make a long story short, I tried all possible combinations of the two processors and the three types of memory. The only time wherever I could get the Pentium E6500 to start was with the factory installed 1 GB memory.  It would give errors of memory with any of the other 2 GB sticks, even when considered individually.  Celeron CPU works very well with them.

    Is there something that I need in order to get the E6500 working with sticks of 2 GB of RAM?

    When you updated the modules of memory did you some they are guaranteed compatible? This isn't an amateur PC equipped of a BIOS level that allows for flexibility in the choice of primary and secondary memory sync settings and take. This means that it is essential that one chooses to upgrade memory that meets the criteria specified in the image below. Otherwise, the way the easiest way to upgrade is to buy only compatible memory guaranteed of leading manufacturers of memory.

    When I search for Compaq 500 b MT I come with a desktop PC. Is this correct? You posted in the notebook section, perhaps by mistake. If you will check, I can move this correct place.

  • Maximum use memory and CPU host

    Hi all

    I have a code that gives me the average cpu, memory of a host of more 1 day use, 7 days and so on.  I want to know is if it is possible to extract the maximum value of CPU usage and the memory of a host in the previous 7 days.  I would like to integrate this in a performance report.  Average usage over a week is fine, but I want to what the maximum value of the previous week was too. If my host CPU hits above xx % at some point, I'd like to be able to see and study if necessary.

    Yes, you can get the maximum CPU usage and the memory of an ESX Server, as the statistical level that curl period is set to 4 (maximum level).

    I suspect you use the cmdlet Get-Stat with the cpu.usage.average and mem.usage.average parameters.

    For the maxima, you must use the cpu.usage.maximum and mem.usage.maximum parameters.

  • DRS cluster resource allocation and CPU

    Hi all

    I have a question about the allocation of CPU resources to the guests in an environment of DRS. I was under the impression that all physical CPU resources are completely abstract the guest virtual computer. However, I see the following behaviors...

    -J' have a cluster DRS with two ESX hosts ~ 59GHz of the total available CPU resources. Physical ESX host computers have several multicore 2.9 GHz (I don't have practical details right now but that is irrelevant)

    -J' have a linux comments running RHEL 3.0 which seems high on slightly less than 2.9 GHz.

    Now there are a lot of resources of cpu without reserve available to the cluster, but this particular virtual machine can't enter any allocation of processor more than a little less than 2.9 GHz.

    So my question is this: are VMs limited CPU resources to the maximum of available resources to a single physical processor on the host, or must it be able to recover more of the DRS cluster resources? (Assuming a single vCPU guest), I can't seem to find any material that provides black and white if that's the case?

    If an SSN processing power is limited to the total amount of CPU resources of a single physical processor in the host, which is recommended for a machine that requires more CPU resources? Adding an another vCPU (and running vSMP)? I was under the impression that vSMP should be avoided unless a particular SMV workload could truly take advantage of SMP?

    See you soon,.

    Ben

    Well, Yes, each vCPU is limited to the resources of a single processor - there is no aggregate CPU by VM resources.  In the end, son of vCPU of a VM are given for a single CPU.  The only way to improve the performance of the virtual machine, it is just as you wrote - add vCPUs if the guest operating system and applications can use.  The cost is that all threads of vCPU for a virtual computer must be taken together, so if the virtual machine is unable to make their use, the waiting time for this and other virtual machines could increase, degrade their performance of the processor.

    A little more info...  An ESX host has one or more contexts of material performance (SESC).  Each core is a HEC.  Each instance of a CPU hyperthreading is also a HEC.  Thus, for a host with two processors Quad-heart and without hyperthreading, the total number of sesc on the host is eight.  Another example; for a host with two single core processors and each processor supports hyperthreading, the total number of sesc is four.

    Each vCPU uses a HEC.  A virtual machine with two vCPUs will use two sesc.  According to VMware, ESX will try to prioritize different sockets for use of the VM before two hearts on the same socket and before hyperthreading sesc on the same socket.

  • Satellite 1800-314: upgrade of memory and CPU

    Hello everyone,

    I'm interested in upgrading my old satellite 1800-314.
    Does anyone know the upgrade of the maximum for this machine processor?
    It does support only pc100 or pc133 memory modules?

    My idea is to upgrade from the origin to a Celeron 1.4 or even a Pentium III Coppermine Celeron 1.1 / Tualatin processor and add more 256 MB machine.

    Thanks in advance,

    André

    Hello Andrew

    Upgrading the CPU is not possible. The processors used in laptops are connected to the motherboard using a process called TCP (tape carrier package). It is a method of permanent connection and is used in the interest of miniaturization and heat dissipation.

    Expansion memory is not a problem. You can use PC100 256 MB (PA3069U - 1 M 25) memory module.
