Troubleshooting performance problems with the mail server on the virtual computer

I have a virtual machine with a mail server installed on a windows OS. But all of a sudden, my clients on the server response times decreased significantly.

This could be the cause of this problem?
It could be to do with the network, storage, or resources, but I don't know what steps I could take to determine fault

Would someone mind helping me with the steps I could take to solve this problem?

Thank you

The below document page 20 and 21 accurate meters, you should look at the virtual machine level.

http://www.VMware.com/files/PDF/Exchange_2010_on_VMware_-_Best_Practices_Guide.PDF

These counters can be used for any virtual computer not only Exchange.  If you are familiar with ESXTOPs I believe that the best way to deep dive in the diagnosis of performance problems.  Also here is a link for these parameters.

  • Performance problem with the guest operating system

    Hello gurus - I have one of the most unusual questions, I ran into a few time.   Here it is:

    I have a guest w2008R2 OS - installed in a 5.1 version of VM 7 vSpherer - which has an Emulex LPe 12002-E 8 GB dual HBA port is assigned to the as 2 PCI (1 device per port) via DirectPath devices

    The guest operating system has an application that performs backup tests.   WWPN of the HBA is zoned in the fabric and declared in the interface of Compellent Storage Center and everything is good here. the application creates a replay of a volume, mount it as a drive, read all the blocks, then dismantles and moves then repeat the process with what ever additional volumes should be safeguarded.   It is so cool I have do this with a VM right and not a physical host?  (would be cool if I had work NPIV but that's another story, not with technology HBA vendor support...)

    So, what's the problem?   Well, the bed the mounted disk backup will work extremely slow as slow as 5MB\sec flow, then during any other activity takes place on the system the flow jumps up to 150MB\sec all of a sudden and will continue to run fast for a long time and finish jobs on time with each work taking a little more than an hour.  But when the slow going the same work (all jobs are the same, they are simply by reading all the blocks of a bunch of 200 GB volumes and wrote a set of NULL value, do not forget this is just test) takes up to 10 hours to complete.

    I think that what is the culprit?   POWER MANAGEMENT.

    I have just about each performance counter and the journal of events known to man and I don't see anything abnormal on the table, ESXi virtual machine, nothing.  But what I see in the newspapers is any kind of activity that could happen in a transparent manner to save energy.

    FACTS on this case:

    -Reservation of memory is defined (it must be for directpath otherwise, you can't power on the virtual machine)

    -Booking CPU - has not been defined before an hour ago, I gave her just a small reserve for this rule, so I do not know if this will help alleviate the slow flow, or have an effect on what I think is a question of power (unit linked) management

    -windows power management is set to high performance never-ever - but not until an hour there doesn't I changed advanced settings for USB Disabled------turned off.  PCI peripheral energy saving setting was already off.  Which is in contradiction with my theory.  But maybe, just maybe, something is broken somewhere, or could be a bug... blah blah blah

    -the HBA, Emulex, as it appears in Device Manager in the guest OS doesn't have a power management tab to disable the feature, I don't see that the adapter VMXNET3 had this tab, and I turn off the power save setting to be conservative, do not think that it was the culprit, but as there is no real data running through the NIC.  The data is simply to be read from the disk mounted, not copied on any wire Ethernet.  never the less, in the Emulex properties is a Details tab and a selection of power data, and performance data indicate you what power mode, the device is, as well as feeding supported systems.  D0: full power, but D3, which shows as supported by the device, is an energy saving mode.   I could not yet attend the setting at the time of slow activity, my good intention as soon as possible. He is currently shooting in D0, full power.

    This is so what I have to offer on this, I hope that its just...   If I'm missing something, or if others have experienced this massive loss of unknown flow without reason and have resolutions, please share.

    If there is a way for me to disable power on the Emulex HBA management inform you please, I don't mind if I stop to enter the firmware, if that was even possible.  But if possible I would disable it immediately before any new tests are executed.

    The root cause of this issue has never been identified by VMware support which for me is a question of ugly.  Reservation of CPU for the VM using directpath IO with HBA installed in it corrected the problem.  I'd be leary with direct path IO.

  • Windows 7-problems with the laptop computer's System32 folder

    I bought this brand new Acer Aspire 5251-1005 computer laptop a week ago from Best Buy and it comes pre-installed with Windows 7. Everything went beautifully except for an unknown problem.

Mail box), this task is not activate Instead, my System32 folder opens... Very weird.

    I searched on several forums. I tried to do a system restore (quite a pain to reinstall everything) and did not work. Tried to activate my guest account to check if my account is corrupted. This was not the case.

    If anyone has a solution (hopefully one that doesn't require too many steps) Please help me!

  • Problem with the virtual store to Windows 7 basic, home

    Hello, I have a problem with Windows 7 64-bit home basic e-store. What happened is that I have a program that I use to make small electronic circuits and it was working fine until a few days when I noticed that the design I was doing seemed to be locked - I can open it but I can't open the second tab of the main window, which I should be able to do. After much research I discovered that the problem was caused by the virtual store of Windows - system registers my designs. I need to disable this feature because it prevents me from doing my work. I tried many things including turning off virtual store in REGEDIT and it doesn't change anything. I have another computer with Windows 7 starter and I have no problem there at all. I searched the internet for ideas and found two to this site http://www.askvg.com/how-to-tweak-user-account-control-uac-options-in-windows-vista-home-basic-home-premium/

    In all no joy. Help, please. I would appreciate only the answers that have been tried and tested not something that is supposed to work.

    Thank you, Ed

    I have a program that I use to make small electronic circuits and it was working fine until a few days ago.

    Given that things worked fine until a few days ago I would use system restore to set Windows back a week.

  • VM hung due to a problem with the virtual processor

    Hello

    Has anyone faced with the following question?

    I use ESXi 5.0. I have several virtual machines run on the ESXi server. There is a virtual machine hung 2 times this month. I had to restart the vSphere Client Console.

    I saw this strange event message in the event tab of ESXi host for this virtual machine:

    Error stack:
    Click OK to restart the virtual machine or Cancel to turn off the virtual machine.
    An error has occurred causing a virtual CPU go into the stop State. If this anomaly had occurred outside of a virtual machine, it would have caused the physical machine restart. The stop State are accessible by properly configuring the virtual machine, a bug in the guest operating system or a problem in VMware ESX.

    Thank you!

  • Problem with the virtual copy exports - JPEG vs DNG

    Hi all - just a quick question - I have a set of photos developed in LIghtroom that include several virtual copies of which I now want to export to in the form of final versions on my hard drive. All virtual copies are B & w versions of the masters (post-processing work also differs slightly on the top of the b & w preset).

    I need a patch of JPEG and DNG files.
    Export to JPEG files seems to work without a hitch and all the pictures come out like in Lightroom.
    Exporting DNG however come with a question - all virtual copies come out as images themselves IE. not virtual copies, but they are more b & w as they are supposed to be, but go out like color.

    Color version masters come out well. Exports of virtual copy have different look (as expected) and the file size slightly different (also planned?) suggesting this only thing missing for me is the parameter b & w.

    I have tried everything to fix this problem with no use - export the virtual copies separately etc. As already said - JPEG works, but DNG does not...

    Someone at - he experienced this and if so any suggestions on how to fix...?

    Thks a lot!

    V

    DNG files are 'RAW' files - they cannot be changed.

    You can export only B & W versions as (pixel database files) as JPG or TIFF

    You can export copies of a DNG, but they are still RAW.

    You can embed data in a DNG file (containing similar to XML with the NAVE sidecar files and raw CR2 files), but editing will be visible in software that can interpret the raw data (like Lightroom or ACR)

    Did you make the registry change that I sent you a private message?

    So, I agree with your statement. These are certainly back up files. The question is; What is backup files?

    Microsoft System Restore only deals with backup of critical system files and registration and records in a hidden folder that is not easily editable. In addition, you verified that this is not enabled for this player. So who is excluded.

    Another possibility is that other Windows, such as Windows Backup service, creates these files. Backup Windows treats the user's choice of the files instead of just the files of backup system.

    Try the following steps.

    1. Click Start, type "backup and restore" and press ENTER.
    2. This will bring up the Windows backup window. It seems to be set up, or it asks you to configure for the first time?
    3. If it is flagged by the look on the left side and you should see an option "disable automatic schedule;" turn this option off. The backup will be not automatically, but you can always do it manually on this screen.
    4. Delete the file Moberdan_HP from the HP_Tools partition.
    5. Improperly editing the registry if you used it.
    6. Reboot the laptop and make sure that the problem is resolved.

  • VMware Workstation with ESX3.5u4 - problems with the virtual machines within ESX3.5u4

    Hello world

    I really need a consultation on this one:

    I'm testing ESX3.5.

    As I don't want to buy any material for now I thought it would be a good idea to test ESX3.5 in my computer.

    I used this model to install ESX3.5 in my computer: http://xtravirt.com/node/100

    ESX3.5 works perfektly in workstation.

    The only problem is that if I create a computer virtual within the VM ESX3.5 works very very slow.

    I searched on the VMware Forum for this problem and found that you need Intel VT enabled to speed things up.

    But I think that my "Intel (r) Core (TM) 2 Quad CPU Q9300 @ 2.50 GHz, 2000 MHz" should have Intel VT.

    Does anyone have any ideas why my VMs on esx3.5 within the short slow workstation?

    Thank you all in advance for the help!

    Material used:

    ASUS P5B

    Intel Quad Core Q9300

    3 GB RAM

    Intel PRO/100 S-Serveradapter Ethernet

    According to your log file, the external VM using VT - x.  I'm afraid, it's as fast as your nested VMS are going to get.  While I would qualify as slow or even nested VM performance very slow, I'm not sure I'd go so far as "very very slow."  It is perhaps a matter of perception.

  • SMTP problem with the recipient's address

    Hi, I made a copy of the function of SMTP Email message send to use it with another port smtp (as 587). Everything works well when the recipient's address is like [email protected] or any what normal address. The problem is when I'm trying to use this function to send an e-mail to an address like [email protected]. Each email to the address of the company is like the second example. Does anyone have an idea to solve this problem?

    I had the same problem with my mail server @msu.edu.

    The problem is that many companies use TLS or SSL security settings.

    There are ways around this problem.

    I have attached a VI that should work for you.

    I can't take credit for the VI, it was given to me by a person on the forums.

    I've just modified it a bit.

    Edit: If you look at the block diagram, upward, there is a node to invoke.

    It's for "SMTP Client", and the element is "host".
    You will need to change that to 'mail.msu.edu' to any server used by your company.

    And you may need to change the port as well.

    I also customized the VI icon, but you can leave if you like it
