• question of delay ESXTOP

  I'm doing a release of the batch from two servers ESX here.

  I run the following command at a time;

  nohup esxtop b d 3 - n 28800 & gt;/mnt/esxshare/vmHostNameHere.csv

  The problem is one of the hosts delaying entered every five seconds, but I say ' d 3'.

  I went through esxtop, hit' and specified 3, then W (write to /root/.esxtop3rc).

  Any suggestions?

  Thank you

• Can question about a possible question, I do it my way?  The end result really me the measure of success?

  I have a question about a theoretical question of the VCAP (specifically the example below).  I could do it is a flash by going directly to the host instead of using the stinking vMA and resxtop, I've always will mark the full points by my way?

  Scenario 11

  < Return | Next >

  Scenario:

  On a specific host of ESXi, a set of virtual machines is not good. You intend to determine the root cause. To do this, you want to collect usage data of resources at a level more granular than vSphere Client performance graphs can provide.

  Requirements:

  • Use resxtop to collect all the statistics for 2 minutes every 3 seconds.
  • Export the data to a CSV file called results.csv.
  • Import the results.csv file in the Windows performance monitor.
  • Use Windows performance monitor to indicate the time of CPU ready for all the virtual machines on the 2 minute period.

  Environmental information:

  • ESXi host: Home - 01.lab.local

• ESXTOP is empty after the capture?

  Hello people,

  I run the following command to esxtop to capture data.

  ESXTOP d 10 - a-b - n 1800 > /tmp/esxtopiometeromni01_05112015.csv

  
  

  I see that the growth of the file running (he looks one of winscp), but eventually I come back to it or when it is done shows 0 B and empty when I opened in excel.

  I was wondering if someone else sees it?

  
  

  Thank you

  The actual writing is only happen when the file is closed and after 1800 iteration data will write do not have enough space to write. That's why you are faced with the question.

  I would suggest that you run the same command and copy the file in file/vmfs/volume/datastore/your name. CSV

  It will work try

• kmoy data on too high esxtop

  Hello

  I do a performance test for my application that is running on the virtual servers with oracle database.

  I'm trying to see what is the storage overhead that is made because the fact that I am running on a virtual server.

  I thought that checking the average kernel memory would be a good parameter to see it.

  When I run esxtop that I get huge numbers on the kmoy/cmd parameter, even when I run for an hour, it is not reached a maximum.

  

  I had 2 questions I would be happy if someone could help me with:

  1. is it possible that the data I see on esxtop is not ture? the numbers are too high (my appliction seems to work very well)

  2 - is a good way to measure the charge made by the vmkernel? (in storage)

  This is probably the reason for the high kmoy numvers:

  When you use VAAI you can't really trust those numbers.

• Understand esxtop output?

  Hi there

  I am fairly new to esx and need some information to help understand the esxtop output. We run esxi 4.1 and I'm trying to figure out if we have some issues of contention of the processor. We run on blade with 4 to 8 core cpu (disabled ht) dell centers. I am of course hunting some response slow times that could be related performance - but I don't know how to interpret the figures here of esxtop - what is normal and when we receive a test system - here - slow response to take a look - here are some of the functioning of the VM on an esxhost - that look like a healthy system?

  In general, I don't see % RDY being a problem when it is less than 5%. A value of 1.6% is certainly nothing to sweat more.

  It is a good resource for answering your questions on what each does and common thresholds numbers to indicate the questions:

• Poor performance of the virtual computer. Questions RDY %

  I installed an environment to ESXi 4.1, and less than a week that I started getting complaints that some virtual machines were slow. Using ESXTOP moment RDY % is usually great, as in simple figures. Then there are times where it spikes up to 80% or hangs around 50% for about 30 seconds.  I know not all the virtual machines have VMTools updated may cause CPU scheduling questions?

  Never, I followed this environment in the past, so I don't know if they had a CPU contention before this upgrade or not, I'm going strictly by the comments of users.

  No, the VMware tools backdated wouldn't interfere.  In fact, you don't have even the VMware Tools installed to a virtual machine running normally.  Will pass you right next to the advanced features and performance gains unrelated to the CPU.  The CPU is the processor there is no driver for this specific to VMware.  Values of loans are quite specific - the virtual machine has something to see CPU wise and his waiting for access to the CPU.

  The physical number of nuclei in the home and what is it (Intel 5500 or 7300 etc.)?  How many virtual machines?  How many virtual processors assigned to hospitality?   How many VMS are multi-CPU?  What is most vCPU per VM on the host?

• Question about CPU Ready time %

  Hello Vmware experts.

  Small question about time loan cpu in esxtop. I have a couple of the virtual machine that has been entrusted to 4 vCPU. When you view their stats in esxtop they indicate the highest term of loan from CPU. I was wondering if this figure is the result of adding the ready time of each vCPU? For example, a 4 x vCPU VM with ready time of 10%, does it really mean 2.5% by vCPU? Should I be concerned about ready time of 10%? I read that the multiple assignment of vCPU can unnecessarily cause time CPU ready. How others decide on how many vCPU they must assign to VM here?

  OK, just realised that was more than just a small question... anyway, would be great if someone could make all this a bit clearer for me.

  Thank you

  BTW, my hosts CPU usage to sit at an average of 25%.

  In vSphere they eased the scheduling of multiple vCPU co even more so that only the vCPU who got ahead of the rest is stopped.  It is always advisable to start with a single vCPU and work your way up if necessary.

  In esxtop you can use the e command to extend the CPU statistics.  In several vCPU machines this will let you see the playing time of each CPU (which should add until you have seen earlier) and it will also allow you to see the % used for each processor.  This should allow you to see if the two vCPU are properly used in a box of vCPU multi.   I had also the CSTP % field shows which is the stop of co and will give you an indiciation of how often vCPU on the machine stopped to allow the other CPU to stand.

• Script Get-stat for VM Perfomance - Questions

  I am writing a script to get data on our virtual machine performance of the measures of depth for CPU and memory.  Its a great project task I have to do for our mgt and so I am writing a script extremely important and vital for our company.  I use the command get-stats and feedback from the messages I posted about get-stat in particular lucd and lebouf who have been very helpful.  But I have collected their answers and writes the script below.  Currently, it must be used with an argument, but I can change it later.  It also uses many counters of cpu and memory that is why it is a long script.  But I have a lot of questions on the script before I run it, I need to be clear with the data I receive in return.  The script is below:

  $vm = $args

  $vmguest = @{N = 'operating System'; {E = {.osfullname (get-vmguest - VM $_)}}

  Get - VM $args | where {$_.} PowerState - eq "Receptor"} | `

  Select name, NumCpu MemoryMB,

  @{N = "Mem.Usage.Average"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.usage.average | Measure-object-propriete value - average). Average}},

  @{N = "Percentage of use memory Maxiumn"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.usage.maximum | Measure-object-propriete value - average). Average}},

  @{N = "Memory use Ko"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.consumed.average | Measure-object-propriete value - average). Average}},

  @{N = "Memory status"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.state.latest | Measure-object-propriete value - average). Average}},

  @{N = "Memory Swapin average ko"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.swapin.average | Measure-object-propriete value - average). Average}},

  @{N = "Memory Swapout average ko"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.swapout.average | Measure-object-propriete value - average). Average}},

  @{N = 'Memory reserved MB capacity'; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat mem.reservedCapacity.average | Measure-object-propriete value - average). Average}},

  @{N = 'Average CPU usage percentage'; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat cpu.usage.average | Measure-object-propriete value - average). Average}},

  @{N = "CPU REady"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat cpu.ready.summation | Measure-object-propriete value - average). Average}},

  @{N = "Maximum percentage of CPU usage"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat cpu.usage.maximum | Measure-object-propriete value - average). Average}},

  @{N = "Use CPU MHZ on average"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat cpu.usagemhz.average | Measure-object-propriete value - average). Average}},

  @{N = "Maximum MHZ CPU utilization"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat cpu.usagemhz.maximum | Measure-object-propriete value - average). Average}},

  @{N = "MHZ CPU reserved"; E = {(get-stat - entity $_ - Start ((Get-Date).))} AddDays(-7)) - finishing (Get-Date) - stat cpu.reservedCapacity.average | Measure-object-propriete value - average). Average}} | `

  Export-Csv c:\stats5.csv

  The questions I have are:

  The first question is I want the stats to be based on the last 7 days, so I used the .adddays (-7).  It would give me the last 7 days stats?

  In my settings of virtual center statistics, I have all interval times checked.  So if I want last 7 days stats, I would use the samples for the interval of 30 minutes duration.  Also I have not used all interval parameter in the get-stat, so my samples will be based on the interval of 30 minutes.  Is this correct?

  Also, I have not used the maxsample interval, so by default I get to use all the values in the sample, and measures will give me the average of all samples (duration 30 min) values in the last 7 days.  Is that correct. ?

  Another key question is that is it possible to get readings of samples for only Monday to Friday, from 06:00-18:00, as this is when the virtual machine is used.  I don't know how this can be done and how it can be incorporated in the above script.  Is this possible to do?

  Also about the measure-object cmdlet, I used to all counters, as for the average values of use of cpu and memory.  I also use counters for cpu and memory max.  Would I need to use the average value of the object of measures to this end, as this counter will give me the max value for cpu/memory for all 7 days, which will be a single value, because I want to know the max value, it achieved, so I don't know if I have to use measure-object with these counters, do I need to use?

  About the ready CPU meter I use, also gives the value in millseconds.  Is it possible to get loan from cpu percentage value as we see in ESXTop because it is easier to understand for the cpuready.  I don't see any counter loan as a percentage of the CPU.  Is it possible to get a value for it.

  With the - equal Start parameter to specify that you want the values from 1 day back.

  This means that you will get the values historical interval 1 and the period interval 5 minutes ago.

  It is the HI1 interval in the scheme of part 1.

  When you specify not one - Start parameter and - finishing you will in effect of the values of historical interval 4, which has a period of 1-day interval.

  In a next blog post, I will talk about default values in the cmdlet Get-Stat.

• using ESXTOP and swap

  I have been instructed by a work colleague to create plugins Nagios that monitor the CPU, memory and swap usage of our ESX machines. Have almost completed the task, I will have questions my head around how an ESX Server uses Swap package. I understand it is swap dedicated to the console that can be listened to via the utility native linux 'free. ' My understanding is that this isn't the Exchange against what my colleague wants to monitor. In my view, that I would like to control the use of the Exchange reported by esxtop.

  My question is how does a server ESX manage swap space and what is actually reported to me by the "SWAP/Mo' aka 'Swap used Mo' statistics given by esxtop?

  An ESX server create/manage space separate global exchange on his SAN attached readers for all the VMS to use or does each VM create/manage their own space to swap out under construction?

  It is more a global exchange space.  It is now by vm, which is represented by the .vswp file located in each virtual machine itself.  The virtual machine will create a swap file that is the difference between the memory allocated for them and the amount of memory reserved for him.  Where a host is out of memory, and share page and balloon does not provide sufficient space, the virtual machine will swap the memory of their vswp file.

• Question of cloning for SSD upgrade on 12 Macbook Pro

  Previously, I did an upgrade to SSD on my Macbook Air to 2012 according to the instructions of JetDrive transcend. Basically connection via USB 3 and using Mac OS X to clear (and format) disc utilities new SSD, then restore again SSD and then remove the original 128 GB SSD and insert the new 480 GB SSD.  For about a month and so far without problem.

  Now I'm trying to 2012 Macbook upgrade my Pro partner (on 10.11.6).  I got a Crucial SSD MX300 to replace his HARD drive.  Crucial comes with (or recommend) Acronis software.  And a lot of the messages of the forum recommend Carbon Copy Clone.

  My question is if I can use the same method for the cloning of the HD as my Macbook Air (just restore disk of Mac OS X utilities)?  This time, I'm upgrading HARD drive and I don't know if something is different.  At the same time, if I got lucky the first time, I don't not ruin Macbook Pro my spouse this time.

  Thank you.

  Yes, you can use disk utility to clone your MBP wives, but unlike CCC, it will not clone the recovery and Partition.
