Hosts in maintenance and CPU/memory consumption mode

Similar Questions

• Host memory consumption is higher than the comments its use (incl. Cached) and overhead?

  I'm under ESXi 5.1. I don't have any custom reserve configured for memory. I'm running in CVS 'Sandy Bridge' mode.

  I noticed earlier than expected host memory consumed on many of my guests. This example comments running Server R2 2012 with the latest version of VMware tools running.

  VMware reports

  

  The guest operating system reports

  

  My understanding is that the "Standby" and "Modified" on the client contains the ' cache ', and the 'Cached' memory prompt is the typical response to this question that I see when people seek only to the memory of 'In Use'. In my case, I'm factoring in the memory cache, my guest shows 3805 MB of real memory, yet my host shows 7.68 GB of memory consumed host, with only 68 MB of general consumption. According to my calculations, the virtual machine should be only consume about 4.28 GB of memory.

  I think I found my answer in the guide 'Understanding memory resources management' here: http://www.vmware.com/files/pdf/mem_mgmt_perf_vsphere5.pdf

  Section "when to retrieve memory host" page 15:

  «In the high State, the use of global memory machine virtual comments is smaller than the size of the host memory.» Whether or not the host memory is overcommitted, the hypervisor will not recover memory via hot-air balloon or permutation. (It is true that when the limit memory VM is not set).

  If memory free host down to the low threshold, the hypervisor begins to find the memory using the balloon. Balloon happens before free memory has actually reached the soft threshold because it takes time for the balloon pilot to allocate and PIN memory physics reviews. Usually, the balloon pilot is able to retrieve the memory in a timely order to keep free memory in the host above the soft line. »

  I checked esxtop, pressing "m" for the display of the memory, and I see that hosts VMKMEM shows 'State', so the only memory of way either currently retrieved is by sharing the page. Only when I start to run out of memory of the host, that this State becomes 'soft' or 'hard', balloon or Exchange will be held in order to free the "free" memory of comments. ESXTOP show my 'minfree"than 940 MB, while it shows that I physically 6960MB of free memory.

• CPU/memory of the ESXi host totally access & usage and temp CPU with PowerCLI.

  Dear all,

  I am struggling with the CPU/memory reading of the host completely & information about the use of PowerCLI and the temperature of the CPU is also very useful for me. I used "Get-VMHost-name" to get VMHost to object, but cannot get its properties such as CpuTotalMhz, CpuUsageMhz, MemoryTotalMB, MemoryUsageMB.

  And also do not know which object has temporary information of the CPU. Thank you!

  You probably have a fairly old PowerCLI version (4.0).

  We'll see if the upgrade solves a number of these problems.

• 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.

• Maintenance and phasing mode

  Dear all,

  I would like to create a script to stop the host (and guests) when a power failure occure. I found a nice script on the web, and I see that he put the host in maintenance immediately mode, and subsequently, he begins to stop guests. I do not understand its purpose.

  I found in the documentation: "the host is in a State of entering Maintenance Mode until all running virtual machines are turned off or migrated to different hosts. You can power on virtual machines or migrate virtual machines to a host of passage in maintenance mode. »

  If the host will not be maintained until guests stops. I thought that maybe in this State there is no network communication between the clients and the clients, then maybe its purpose is to keep the guest in a more consistent state, but I don't know.

  So my question is what is the real reason to be maintenance host mode prior to the guests?

  Thank you very much

  Hello

  One advantage is that no new VMs will be migrated to this host by the DRS.

  If otherwise you stop VMs, that host suddenly will have tons of free to use resources, DRS could therefore kick in and migrate new virtual machines on that host.

  On the otherside, putting the host in maintenance mode can even save you having to close all virtual machines if your infrastructure is designed so that it:

  If you have a cluster stretched, or different power for lack of domains in a domain controller, you may experience a loss of power on we'll say half of your ESXi hosts in a cluster. If your second half of the cluster has a power source and is not affected, put the soon-to-fail hosts in maintenance mode and let the DRS to evacuate VMS, is the fastest way to move your virtual machines with other hosts.

• 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

• 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.

• The host in maintenance mode

  Is there a way to determine who put the hosts in maintenance mode and when (if there is no tasks/events in VC) VC, D/B.

  Something similar in the context of "that erased my VM.

  THX,

  Lalit

  Of course, look for the EnteredMaintenanceModeEvent event.

  Something like that

  Get-VIEvent -Entity (Get-VMHost ) -Start (Get-Date).AddDays(-7 ) | where {$_.GetType().Name -eq "EnteredMaintenanceModeEvent"} |Select @{N="Host";E={$_.Host.Name}},CreatedTime,UserName
  

  This will search for all hosts in the last 7 days.

• While putting the host in maintenance mode, I'm stuck at 2%

  While putting the host in maintenance mode, I'm stuck at 2%

  With the message at 2% it get stuck below.

  "Waiting for machines virtual to be powered off or migrated. In a DRS cluster, see the page of defects on the tab of the DRS for troubleshooting. "

  When you put a host in Maintenance Mode, the virtual machine will be generally migrated to other hosts automatically by the Drs there are reasons why it would not work.

  Some of them are:

  • You do not have DRS licensed (only included in Enterprise and Enterprise Plus)
  • DRS is set to manual
  • You have the DRS, but the virtual machine connected local resources (such as the CD-ROM player,...)
  • You have the DRS, but there are no hosts available because of rules configured to affinity/Anti-Affinity
  • Not available on other host resources

  In both cases, you will have to solve the issue and migrate virtual machines to other hosts or stop the virtual machines. As soon as he has no more power on virtual machines on the host, it will enter into Maintenance Mode.

• 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.

  Kind regards

• 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.
