• Alarming on slot voltage vCPUs at the Cluster level

  I'm trying to implement a rule that set an alarm when powered vCPUs in a cluster exceeds a certain level.  The following function works very well when I create a dashboard, but when I try to bring in a rule, I can't get the values of the scope of the VM.  The 'State' variable is assigned to Null.

  cluster = args ['clusters'];

  esxHosts = cluster.get ("esxServers");

  Integer vCPUCount = 0;

  for {(esxHost to esxHosts)

  VM = esxHost.get("virtualMachines");

  for (VM in SMV) {}

  State = VM.get("vmState/current/value");

  If (State == "receptor") {}

  vCPUs = VM.get("cpus/cores/current/average");

  vCPUCount += vCPUs.

  }

  }

  }

  Return vCPUCount;

  I'd appreciate any help you can provide!

  as a general rule, I usually do something like this:

  DS = server. DataService

  cluster = scope;

  esxHosts = cluster.get ("esxServers");

  Integer vCPUCount = 0;

  for {(esxHost to esxHosts)

  VM = esxHost.get("virtualMachines");

  for (VM in SMV) {}

  State = ds.retrieveLatestValue(VM,'vmState').getValue)

  If (State == "receptor") {}

  vCPUs = ds.retrieveLatestValue(VM.cpus,'cores').getValue () .getAvg)

  vCPUCount += vCPUs.

• total consumption on the cluster by vm

  My environment consists of a virtual centre with a bunch of 3 boxes of esx. We also use VMotion to move 3 servers. Is it possible to get using powershell, how a single virtual machine consumes total resources on the cluster vmware and who brings in a csv file? I ask for a single virtual machine, but really, I'm looking in the csv file to list all VM and what amount of resources (such as mem.consumed.average

  mem.sysUsage.average and cpu.usage.average) they consume on the cluster.

  Any help would be greatly appreciated!

  We will address this problem step by step.

  (1) statistics for virtual machines that may have been vmotioned

  There is a problem when you ask - real-time statistics.

  The reason is that these data are stored on the ESX Server, not on the virtual circuit.

  The cmdlet Get-Stat returns only the data of the ESX host on which the virtual machine is running.

  So, if we want to see statistical data for virtual machines that have been vmotioned, it is advisable to opt for one of the historical intervals!

  Note that this is not a problem VITK, QueryPerf in the SDK method displays the same behavior.

  (2) how to calculate the % of its use against the cluster?

  I don't think that the script should ask the percentages for statistics (e.g., cpu.usage.average).

  In this case, it is better to go to statistics expressed in a value for which we also have a total value at the cluster level.

  That means the script should measure for example use of the processor in MHz (cpu.usagemhz.average).

  (3) as the resources available on the cluster that take us?

  On a cluster, we can make a simple addition of the resources available on each of the clusternodes.

  For example, a 3-node cluster, where each node has a 2,669 GHz quadcore would have 3 x 4 x 2,669 GHz of CPU resources available.

  But that's what we want to measure the consumption of the virtual machine against?

  Only part of the total resources available on the server (a clusternode) ESX Server is allocated to the guests.

  Part of available resources go to the "system".

  Given the previous the next script, in my view, expresses the CPU usage and the memory of each virtual machine as a percentage of the available cluster resources.

  $report = @()
  
  $cluster = Get-Cluster  | Get-View
  $clusterCPU = $cluster.Summary.EffectiveCpu
  $clusterMem = $cluster.Summary.EffectiveMemory * 1Mb
  
  $from = [Datetime]"03/05/2009 00:00"
  $to = [Datetime]"03/05/2009 23:59"
  
  Get-VM | % {
       $cpu = $_ | Get-Stat -Stat cpu.usagemhz.average -IntervalMins 5 -Start $from -Finish $to
       $mem = $_ | Get-Stat -Stat mem.consumed.average -IntervalMins 5 -Start $from -Finish $to
       for($i=0; $i -lt $cpu.Count; $i++){
            $row = "" | select VM, Timestamp, CPUperc, Memperc
            $row.VM = $cpu[$i].Entity.Name
            $row.Timestamp = $cpu[$i].Timestamp
            $row.CPUperc = "{0:N2}" -f ($cpu[$i].Value / $clusterCPU * 100)
            $row.Memperc = "{0:N4}" -f ($mem[$i].Value / $clusterMem * 100)
            $report += $row
       }
  }

• New analysis of data warehouses... at the level of the Cluster with PowerCLI 5?

  Hello

  Since vSphere has been provided (I think) the option to open a new analysis of the HBA on every host in the cluster ESXs is available in the GUI if you click with the right button on the cluster, select analyze again to data warehouses.

  I have read several threads from people requesting this option in Powercli but have not found a solution for this.

  When you do Get-Cluster-name | Get-vmhost | Get-vmhoststorage - RescanAllHBA to do this, the new analysis a host once in the cluster.

  Is there a solution for this now in PowerCLI 5.0?

  As far as I know, there is still no option to launch the new analysis across the cluster in paralel.

• Not enough resources to meet the level of HA failover in the cluster in data center

  Hi guys,.

  We just migrated our ESX 4 clusters to a new VirtualCenter (version of Base 2.5 - & gt; 2.5U4), and one of the clusters is showing «insufficient resources to meet the HA...» "error message.

  First of all - is it possible to refine what host is at the origin of the problem (or VC), or is it a real issue with ability?

  I followed some VMTN articles to avoid the usual bugs: -.

  • Ensure all host FQDN, and domain names are lowercase in VC - home | Configuration | DNS and routing

  • Make sure while tiny in/etc/hosts, sysconfig, /etc/vmware/esx.conf and/proc/sys/kernel/hostname on all 4 hosts.

  • Deactivated / reactivated HA on the cluster

  • Looked into the VC vpxd*.log the period of time during which HA was past - but don't know what to look for?  There are a few warnings such as:

  • Warning 'Local' 5940] FormatField: optional unset (vim.event.VmUuidAssignedEvent.vm)

  • "VpxProfiler" 2752 WARNING] InvtHostSyncLRO::StartWork took ms 2203

  • Warning 'Local' 6032] FormatField: optional unset (vim.event.HostDasErrorEvent.message)

  • "PropertyJournal" 5380 WARNING] ERProviderImpl & lt; BaseT & gt; : _GetChanges: global version name overflow host-600

  • .. .etc

  There are 4 hosts in the cluster - and capacity seems ok.  I watched [doc ability vmwarewolfs | ] http://www.vmwarewolf.com/HA-failover-capacity/ [ ], but am not sure that I totally understand it.

  4 guests look like:

  1 - 32 GB RAM (22 in use) / 17600 Mhz CPU (5548 current usage)

  2 - 64 GB RAM (31 in use) / 17600 Mhz CPU (7661 current usage)

  3 - 32 GB RAM (18 in use) / 17600 Mhz CPU (4210 current usage)

  4 - 64 GB RAM (20 in service) / 17600 Mhz CPU (7440 current usage)

  How can I work if there are really insufficient resources or is it a bug that will be bypassed by creating a new cluster and migrate more hosts in maintenance mode?

  Thanks for your time guys!

  Dan

  You have all vms with a high reserve (memory or cpu)? If so, this can cause the HA being too conservative admission control algorithm. The guide of availability of vSphere for details on the algorithm of "slot" - http://www.vmware.com/pdf/vsphere4/r40/vsp_40_availability.pdf, especially pages 13-16. Some of the mentioned options are only available in vSphere 4, but the basic mechanism is also applicable to the VC 2.5.

  VC 2.5 does not expose the details of accommodation through the user interface as vSphere 4, but you can get some information in the vpxd newspaper. Try the power on a virtual machine (you should get an error message on failover insufficient capacity) and look in the logs of vpxd for 'Housing news' - the following lines should have a few details - download those to this topic if you need help their deciphering.

• Script to reconfigure the cluster HA

  Hello

  Here, I wrote a script that changes the PA according to the entry. However I have a few questions because of this script is the error handling...

  }

  }

  If ($n - eq. 1)

  {Write {"are component snap"}}

  on the other

  Here, I want to insert where it should be able to check the settings and then performs the action of the error handling.

  You guys could help me check the parameters or arguments.

  Thanks,

  * Priya

  I'm not sure that I understood what you want, but if it is the validation of the parameters in a function, you can do the following 100%.

  (1) to define the type of the parameter

  
  param ([string]$param1, [int]$param2)
  ...
  

  PS will give an error message when the type of the parameters passed is not correct.

  (2) check that the parameter is not empty

  
  param([string]$param1=$(Throw "Parameter missing: -Param1 string"),
            [int]$param2=$(Throw "Parameter missing: -Param2 int"))
  ....
  

  (3) If you need more specific tests on your settings, you must include you this logic in your script.

  Note that the Param statement in PowerShell v2 has been revised and is now a number of additional options.

• pass-through of a Subvi to the next level with continuously running loops

  Hi all

  It is a very simple question, for some reason, data available as a Subvi indicator doesn't it up level vi. I think it might be something to do with the while loop I use, but I cannot understand, any help will be appreciated. I don't think I quite understand how data comes out of a loop constantly running.

  GPSdisplay runs a driver called GPS.vi (im not worried for my event structure immediately, which could be bad, but I am yet to test this bit yet) 1 probe should have the values of GPSCluster

  

  Loop in GPS.vi. GPSCluster (sensor 2) is updated correctly

  

  I can't work on why the data is not passed to GPSCluster at the top of page vi

  

  Hi bennymacca,

  I think that you are on the right track with a FGV. You can do quite easily with GPS vi you have.

  Before going further, your GPS while loop will return only the last reading and because the Boolean value of "Read" output state is set to FALSE, it will not stop. You see it out at all? The logic, I read, once entering this while loop, that he will not stop until said.

  There are 3 options you can try.

  (1) use a FGV, because you are looking in. To do this, you need to change the boolean TRUE State and set records in the GPSCluster - to analyze the information around, holding each time the vi is called and you leave. Outside the while loop you will thread to the top of the cluster to the indicator that you want to collect (OR you can have it inside the case statement where you read - be careful here, if).

  (2) in the main code, above the frame of the sequence, you can place the GPS vi while loop (the ' read' a), given the State of the boolean connected to a local variable of the Stop button. This while loop will start depending on how feels LV, wire, one line error for the two while loop and Frame (indicating that the two are to run in a parallel mode), OR you can put it in a case statement and say 'go' when you want to start playback. In this while loop, you can then copy the data to read directly in your variable Cluster that it is generated.

  But with (2), you move yourself away from the purpose of the GPS vi, which would be to bring all the features of the GPS functionality in a vi - which is a good idea.

  (3) put a condition on the State of the Boolean case "Read" statement - just make it TRUE when you want to stop reading the data (do you have a time or a condition, you can check here?). Even by doing this, you would / may still need to shift on your lease registers loop to keep the data for each iteration.

  I hope that all of this help. See you soon. David.

• New host is added to the cluster

  I took over the administration of a cluster 4 host running ESX 4 U1.  The processors are Xeon E5335.  The admin before ordered 2 extra guests with Xeon E5620 CPUs.  I wonder if vmotion will work when I add new hosts, it looks like in KB, I found that I have to change the mask on new hosts and select CVS on all hosts for this to work.  Any help would be greatly appreciated.

  Just turn on CVS at the level of the cluster before adding new hosts. And vMotion works perfectly after that.

  It seems that the value for minextents for your tablespace is located at 56 and tablespace doesnot have enough space to allocate as much quantity of memory regarding the contiguoes extensions. Then, either you need to add a data file tablespace or resize the existing table. You can also try the decrease of the Minextents value for the tablespace if you think this tablespace has enough space to accommodate segments. Better would be to add a file or resize a file.

• Auto micro adjusts the input level

  Hi all

  I tried this several times and never seem to be able to find an answer that works...  When I talk in my microphone on my macbook pro, it adjusts permanently the input levels, so in mid-sentence volume varies (always at peak).  It is extremely annoying, and there seems no obvious way to a certain volume of recording.  Any help here?

  Thank you!

  Hi Aprilstern,

  I understand that the input of your Mac's built-in microphone volume seems to be fluctuating when you save. In this case, if you use Mac OS X Yosemite or earlier, you may want to turn off noise reduction in system preferences > Sound > entry.

  OS X Yosemite: adjust the settings of your computer's audio input

• Q: I have transferred all my iPhone 6 more apps to my iPad Pro. When I went in Clash of Clans I expected to be at the point, (level) I am with my phone?

  Q: I have transferred all my iPhone 6 more apps to my iPad Pro. When I went in Clash of Clans I expected to be at the point, (level) I am with my phone? Rather than start from the beginning!

  Any tips?

  Are you signed the same center of game username and password?

  The other thing I can think is clash of Clans a universal application? The button 'get' was a sign? If it isn't then you can play a different game... by that I mean, there's game has scaled for iPHones and game set B nationally for iPads... they have the same game but different - just like a cover can be the same brand and color but different model for different iPads.

  You can contact the support of the COC and see if they can transfer progress from one device to another or if there is something you need to do to move your progress to the wire
