  One way to do this easier would be to create an array with the elements you want on it, as the name of the virtual machine, the use of the processor etc... and then you can filter/sort by CPU utilization, memory usage etc. and only have the Top 10 or anything else you like.

• Script of PowerCLI to capture ESXi host CPU & memory

  Hi all

  I'm having the time more difficult to find a script that will give me ESXi host CPU and memory. I just need something simple, if there is such a thing?

  Example of what I'm looking for:

  Host name	Ability of GHz CPU	CPU GHz used	Free GHz CPU

  Host name	The memory capacity	The memory used	Free memory

  Help, please.

  You mean like this

  Get-VMHost-name MyEsx |

  Select Name,

  @{N = 'GHz CPU capacity'; E = {[math]: tour ($_.)} (CpuTotalMhz/1000,2)}},

  @{N = "GHz CPU used"; E = {[math]: tour ($_.)} (CpuUsageMhz/1000,2)}},

  @{N = "CPU GHz free"; E = {[math]: Round (($_.))} CpuTotalMhz - $_. {{(CpuUsageMhz) / 1000,2)}}.

  @{N = "GB memory capacity"; E = {[math]: tour ($_.)} (MemoryTotalGB, 2)}},

  @{N = 'Memory used GB'; E = {[math]: tour ($_.)} (MemoryUsageGB, 2)}},

  @{N = "GB free memory"; E = {[math]: Round (($_.))} MemoryTotalGB - $_. {{(MemoryUsageGB), 2)}}

• Reboot planned ESXi host or guest vm programmed

  Hello

  I am new to Linux, but basically I am trying to automate backups on my server ESXi 3.5, I managed to use tasks planned windows to stop the comment of 2003 Server (only 1 guest on the ESXi host at this time) and then at 23:00 then I use regular Veeam Backup at 23:30 to make a copy of all VDMK & files to store data to a NFS volume I set up as a data from a store another Windows XP computer. Everything all right at this stage!

  But...

  How to make a regular guest VM to restart (Windows 2003 Server) to 06:00 before the start of the work, or I can restart all of the ESXI server at 6:00 so it will bring up the guest with it OS? (I activated the operating system invited to start restart esxi)

  To clarify, is there a simple way to automate a check from 06:00 the esxi server or a vmware guest?

  I might add this, as a scheduled task windows or bat with the following command line at 06:00:

  The command whith:

  "C:\Program VIX\vmrun.exe VMware."

• What metrics to use for memory capacity planning? Active or consumed (in request or use vROPS)

  Hey all,.

  I was wondering once more what metrics to use for memory capacity planning. Since the information from different sources (for example your ESXi host needs more RAM to Iwan Rahabok or VMworld 2012: Session VSP1729 - virtualized memory understanding performance management - Eric Sloof - NTPRO.NL Kit Colbert) pointing all assets (vROPS request), I expect that when we have high memory consumption / use in vCenter there will be no balloon / compression / permutation.

  Also the metric active / request should not be used for all workloads (e.g. Java / DB), why is - this? I have not found the reason of this anywhere, only the fact.

  Other sources such as Mark Achtemichuk suggests using consumed/use, which is the opposite (Understanding Active Memory - VMware vSphere Blog - Articles VMware vSphere).

  So I thought I'll with active / demand as metric and ignoring the warnings inside of vCenter.

  But the last time we have fixed half of our group, we had consumed/high memory usage and the vCenter began to inflate, compress, and finally to Exchange. Not a lot but I had not expected that, because memory active was only a small percentage of consumed.

  Can someone explain to me why this happened and who is right on this issue.

  Kind regards

  jengl

  jengl I don't know if you asked the wrong question, or I give the wrong answer :-)

  It is always good to attach screenshots, background to the issues, and what exactly you are trying to solve.

  You wrote:

  So to summarize:

  -ESXi uses consume to decide when to start the recovery techniques of memory RAM

  -To rightsize VMs for RAM, you must use the counter inside the BONE, not active

  -If you do not want to commit too much RAM and have a lot of the balloon you should right-size your virtual machines or extend the RAM / buy additional servers

  Please correct me if I'm wrong.

  My answer: you are right. If you do not have access to the guest operating system, then Active VM and VM consumed are better guess. Better than nothing :-)

  Sizing sizing of VM and ESXi are 2 different things (2 use cases) different. Please don't mix up the as soon as they are confusing. Do not try to resize the virtual machine when you are sizing the ESXi, unless you have a control total on them.

  You wrote:

  The question for me is: how many cache (standby under Windows) inside the VM is really necessary for the virtual machine to get the best performance without wasting resources. Perhaps this issue can be resolved only by tests or do you know another option?

  My answer: it's a different topic brother :-) It is different, because it is within a guest operating system (Windows in this case) and is no longer at the level of the ESXi. Suggest that post you another, possibly under Windows or vSphere too :-)

• 8.3 OMSA @ ESXi 6.0 U2 @ R515-> cannot log into the website OMSA to ESXi HOST.--

  Hello guys.

  I've updated my ESXi of U3 5.0 to 6.0 U2 and I lost my OMSA. I can not connect from the web page.

  For the update of the host, I used this ISO file:
  . VMware-VMvisor-Installer-6.0.0.update02-3620759.x86_64-Dell_Customized-A00.iso

  After that, I installed OM-SrvAdmin-Dell-Web-WINX64-8.3.0-1908_A00. EXE to a VM W2012S to this host. I can open the web site to connect, but when I try to connect to my ESXi HOST, I received this message: failed to connect... connection error.

  When I saw that I began to check a few things, I ran: 'list of vib software esxcli' and I saw:

• Connect 2 ESXi hosts to array SAS MD3220

  I have two R620s who go to the server as a host for the VM for several web servers (in a Windows NETWORK load balancing) and two other R620s which will be considered as physical database servers (in a Failover Cluster) and have to apply to a single Bay MD3220 SAS. The DB cluster will host the databases shared on a virtual disk and a data store shared on another virtual drive on the Bay. ESXi hosts will store their vmx/vmdk files elsewhere on the Board.

  I'm still waiting for delivery of the second DB server, but in the meantime, I installed the first and he speaks with success to the table - I run MDSM on that server and the server is successfully connected to DB and filestore volumes. guess I'm having a little problem with the second server.

  I installed ESXi on both VM hosts. I guess the next step is to save in MDSM, but MDSM is not automatically host port identifiers as assigned. Does?

  My next guess would be to identify manually port host identifiers, but how can I determine what are their respective IDs? I couldn't see anything obvious in the BIOS.

  I have currently two independent hosts to VM with ESXi installed v5.1 - I have not created a VM vCenter again because the host does not have access to the storage Bay (!), so I can pair together for HA hosts, etc. As a broader question, given what I want to achieve, how should I be going to this topic?

  Indeed, you will need to register the VMware hosts in MDSM yourself. There is no agent to have a VMware host register automatically on the SAN (at the regular difference in Windows and linux).

  You may be able to find the WWN of the HBA SAS in the SAS controller bios.

  The only other way I know not to register the correct WWN with the server is intrusive, but not so hard:

  -Stop your Windows (cluster SQL) servers

  -Stop the VMware servers

  -power of the MD3220 downwards

  -power up the MD3220

  -power up to one of the servers Windows (one that has MDSM on it)

  -power up the VMware Server 1

  In MDSM, you can now save this first VMware Server.

  Turn on the other 2 servers and register the 2nd VMware Server.

  I found that only shutting down 1 VMware server is not erase the memory of the MD whose WWNS are connected and there is no way to find which ports you enter the WWN in question.

• ESXi Shared memory of commom and UCS B200M2

  I vSphere 4.x environment to IBM 3650 and half B200M2 (a group consisting of the 3650 and a group consisting of the B200M2).  IBM machines are 2 socket quad core with 34 GB of memory and Cisco are 2 Socket 6 core with 48 GB of memory.  Workloads on IBM and Cisco ESXi hosts are the same.  For most of 2008 and Windows 2003 machines.  On IBM machines, I move 1 GB, 2 GB of shared memory (common shared memory - amount of memory that is shared by all virtual machines powered and vSphere services on host machine) on each ESXi host.  On Cisco machines, I get around 15 MB on each ESXi host. Considering that it is one of the great features of VMware (sharing of memory) why is there such a huge disparity between the machines?  Is it because the Cisco blades NUMA machines?  Is there a setting I'm missing?  It's a huge difference.  I don't regret getting the UCS stuff I like it but it is the big novelty of the VMware that does not work with the UCS.

• Machines and ESXi ESXi virtual memory best practical considerations

  We have a new Infrastructure built current and capacity planning that happens. It would help if someone can provide me with best practices on the hardware requirements while building ESXI hosts.

• Update Server VC and 5.5 ESXi hosts to update 3 b (Build 3248547)

  I'm in vCenter Server 5.5 and 5.5 ESXi hosts.  Both are updated 3A, patched to version 201510001, which is the build 3116895.  I plan the upgrade of update 3 b (Build 3248547) and I'm a little confused on the question of SSLv3.

  I wonder if this point below ESXi55 U3b & VC 55U3b Known Issues applies to my config:

  ESXi does not automatically added to the inventory of the vCenter servers
  If you install an earlier version of vCenter Server and vSphere Update Manager for ESXi 5.5 updated 3B, then after the task of sanitation, ESXi does not automatically added to the VC inventory. Remediation process never gets done and ESXi State of connection in the VC inventory is presented as disconnected. Solution: When you restart ESXi after reorganization process is started, enable SSLv3 on ESXi (which is disabled by default). This will ensure that ESXi is added to the VC inventory automatically in minutes and sanitation as completed.

  If I'm reading things correctly, upgrade to vCenter Server to 3 b first and then upgrade the ESXi hosts, will avoid lost communication problems.  Can anyone confirm?

  It should be good if you update vCenter first.

  The problem is that pre - U3b vCenter 5.5 forces an SSLv3 connection when connecting to an ESXi host on port 443 (not the reverse). It does this, even if the host ESXi and vCenter SSL/TLS libraries actually support TLS 1.0 + since at least vSphere 4.0.

  So when you update one host to 5.5 U3b, the oldest vCenter again will try to force a connection SSLv3 that will fail, since SSLv3 has been disabled to the host. If you're updating vCenter, first of all, it will initiate a good TLS 1.0 + connection to more similar and updated hosts.

  Here is an explanation of the (pre - U3b) vCenter SSLv3 handshake behavior:

• 5.5u2 ESXi host will not mount CF data warehouses

  I am the admin in a test lab, so many times I have to "make do" with what I have for the material.  I recently reassigned a R910 Dell with 64 GB memory in a 5.5u2 ESXi host.  It has some storage SAS (2.5 to) and some (CT 11) directly connected FC storage and some FC HBAs for use by VMs to send data to the tape library.

  Recently, we had a power failure, and this host does not reconnect to the CF storage when she returned to the top.  (Duty to "make do" with what I means not having is not the capabilities of UPS).  I can tell the host of HBA see it properly and sees the LUNS on RAID controllers, but refuses to mount.  I go through the add storage Wizard, and he sees that there is a store of data storage VMFS, but always refuses to mount.  I also tried to remove the redirection to the two FC HBA that have been set up for this purpose, but it made no difference.

  I have now three users unable to work because they cannot access their virtual machines on storage of this FC.  I can't even transfer them off to use the SAS storage form.

  I think it might be the cause file system damage, but I'm not sure.  Someone at - it suggestions?

  Have you ever tried to set up data warehouses from the command line (see, for example, http://kb.vmware.com/kb/1011387)?

• Change of identification 5.0 ESXi Hosts DNS

  I have a 5.0 vSphere infrastructure not integrated with Active Directory.

  Either the vCenter and ESXi hosts have a DNS identification that uses a domain name that is identical to an existing Active Directory domain.

  To avoid potential conflicts, I plan to change the domain name in the DNS configuration, as described on page 74 of the manual on the https://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-501-networking-guide.pdf page.

  Can I just change the DNS domain name without having to restart ESXi hosts?

  The domain name DNS influence the affiliation of ESXi in a cluster (not integrated into AD)?

  Should I change the name of the DNS domain of the vCenter as well?

  Is there anything else I should consider?

  Concerning

  I recommend you change the domain name on all systems related to the vpshere environment.

  Don't forget to also change your dns server DNS records. I guess they are hooked up with the right dns name vCenter?

• Should the RAM for an ESXi host replaced the same ones remaining?

  Hello

  We are running a cluster of servers ESXi 5.1 - 2 of them are Xeon E7440 2.4 GHz (64 GB of RAM) and 1 of them is Xeon X 5460 3.16 GHz (32 GB of RAM).

  Currently, the use of the memory of all three ESXi hosts are about 60%.

  We will replace the Xeon X 5460 server with a new physical server.  We would like to ask for your opinion how much RAM you must order (my manager of door on the cost of the new server).

  Thank you

  Hi again Tony,

  1. No, it is not high at all. You should begin to worry about this, after reaching approximately 85-90%.
  2. My short experience with clusters of memory-unbalanced, adding that more memory would be a lot like the DRS manages memory locations & 'kindness host' in the right direction, but I'm not really sure how that would turn out in the long term. If you decide to present more memory to your server, it would be possible to upgrade the other two guests sooner than later
  3. Yes, ask the seller would be the right thing to do. Please note that you will need to put in place an enhanced vMotion to conform to your next "older" CPU then, because you'll have something other than X 5460. I guess you'll have to "intensify" a generation or two, depending on what you have found.

• When was the last time that 5.5 ESXi host not re-initialized and total times restarted last month.

  Hi team,

  We have more than 100 ESXi host in our environment, and we need to know when was the last time ESXi host rebooted and no times restarted last month. Please help me get the power cli script. Any help will be much appreciated. Thank you

  Thank you

  VMware tech

  OK, so the ESXi nodes were hard started (as if you pushed the power button).

  This is probably why the task for a planned restart does not turn upward.

  Do you see the ESXi nodes with the following script?

  It shows the events where the connection to a host has been lost.

  $start = (get-Date). AddDays(-7)

  Get-VIEvent - MaxSamples ([int]: MaxValue)-start $start |

  where {$_-is [VMware.Vim.HostConnectionLostEvent]} |

• ESXi host security

  What is a good strategy to use AD to authenticate access to an ESXi host?  (I don't want to use root).  Can I create multiple groups in AD with different levels of privileges to access an ESXi host using SSH?  Or can I only use the ESXADMINS of the group do?

  Thank you!

  Hello

  Fixing a VMDK broken-> glass break

  Configuration of the equipment of CLI-> break glass

  With the help of AD does not lighten the need to reset the password every day 50 +. That will still happen. AD simply adds the ability to add other users who are managed remotely, it does not control 'root '. So you still have to do that. This is why I don't really like integrate AD ESXi, I rather integrate HyTrust and let HyTrust manage my passwords. It will change them automatically for you every X days. It will be Thycotic and Xceedium actually. Two other password systems. You can already use one in your store, if you do, see if it will work with ESXi.

  Regarding the ESXCLI, some esxcli orders can be executed with nothing more than your credentials of vCenter. Some require 'root' access to run. Even user access may not work. If you use the vSphere Management Assistant, you can control who does what on a host as well. I prefer it on powershell. Or sit on a Windows or Linux host vCLI. I have this and the use of powershell. Adapt the tool to the solution. I use them all according to what it takes. My scanner to 'security' for example uses vCLI/SDK on Linux and uses your credentials from vCenter for most. If it requires identification information specific vSphere I report only to VMware to solve.

  I'd build my own tool using puppets, Chief, or Perl and wait for it to change passwords, set the new password in an encrypted safe and another tool to recover, connect through a proxy and capture my actions for the purposes of audit, can once again change the password automatically with 50 + guests. Again, it is a glass break situation that requires additional verification. All of these features can be duplicated using the free tools and a little ingenuity, but it can just take the time to do.
