ESXI4.1 has how often is DRS control the CPU usage?

ESXI4.1 has how often is DRS controls the use of the CPU on the host?

I have 16 ESX host. Some of the hosts reach very hight CPU use, up to 98%, although some are as low as 52%. I understand DRS moves virtual machines only when you have to. I wonder how often it checks. Is there a set period of time, or DRS works in real time to check the hosts. Virtual machines are finally left guests busy, although guests were constantly busy today, about 90% + CPU, while some have been systematically 50%.

On the 16 hosts, we have configured 1 host failover capability and the current capacity of 11 host failover. Affinity rules apply only to a limited number of virtual machines (about 6) of about 300.

By default DRS is called every 300 seconds.

Best regards, Robert

  • Windows XP I often setup.exe keeping the CPU at 100% for at least a few minutes.

    Running Windows XP, I often setup.exe keeping the CPU at 100% for at least a few minutes... this process can be completed or ignored?

    "Setup.exe" is a generic term used by many applications.  The short answer is 'yes', it's OK to complete the process, but you really need to know what it is and why it continues to run.

    You probably need to download, install, update and run these free malware scanner (not at the same time):
    MalwareBytes AntiMalware
    SUPERAntiSpyware

    If that is not fix things, and assuming that this process begins when you start the computer, download, install, and run Autoruns.  When Autoruns has finished scanning, click the 'Connection' tab and look for the line that contains "setup.exe".  You can just uncheck the box on the left, or remove the item, which will prevent the routine of starting when Windows starts.

    Preferably, however, you should look at the path containing setup.exe where you should be able to deduce what application is trying to set itself up.  You can then take the appropriate measures, which may be simply delete the folder that contains the file.  Note that if you delete the file, you must ALSO remove the line in Autoruns, otherwise you will get a "file not found" error every time Windows starts.

    Hello

    If you plan to build your app for Windows, you can use .NET classes. (System.PerformanceCounter), there is a simple example with LabVIEW:

  • How to set up notification by e-mail to the CPU usage complete on OEM12c?

    I found a Doc Oracle, the way that e-mail notifications are configured? How can I check that after setting the notifications?

    4.1.2.3 to subscribe to receive e-mail for the Incident rules

    An incident rule is a rule defined by the user that specifies the criteria by which the notice should be sent for specific events that make up the incident. A set of collateral rules, as its name suggests, consists of one or more rules associated with the same incident.

    When you create an incident rule, you specify criteria such as targets that you are interested in, the types of events you want that the rule applies to. More precisely, for a given rule, you can specify the criteria that you are interested in and the methods of notification (such as email) to be used for sending these notifications. For example, you can set up a rule that when a database crashes or any database backup job fails, e-mail should be sent and "disruption log" notification method must be called. Or you can set another rule that when the CPU or memory of any host using reach the critical severities, SNMP traps to be sent to another management console. Flexibility of notification is reinforced by the fact that with a single rule, you can perform multiple actions depending on specific conditions. Example: When a condition of monitoring such as machine use of memory, for an incident severity of 'warning' (to 80% memory usage), send an e-mail message to administrator if gravity is "critical" (99% memory usage), the administrator of the page immediately.

    You can subscribe to a rule you have already created.

    In the configuration menu, select cases, and then select rules of the Incident.

    On the rules of the Incident - all company page rules, click the rule set containing rule climbing incidents in question and click on change... Rules are created as part of a set of rules.

    Note: where there is no set of existing rules, create a rule set by clicking Create Rule Set... Then, you create the rule in the context of the creation of the rule set.

    In the section the page rules change a game rule, select the rule of climbing and click on change...
    Go to the Add Actions page.
    Select the action that intensifies the incident and click on change...

  • How can I remotely control the music on the 4th generation Apple TV

    On the 3rd generation Apple TV, I could use the app Remote for artist, Albums, songs and playlists which was to play directly from the Apple TV remote. This allowed me to sit on the deck and set or change my playlist remotely while my Apple TV played on and on. I couldn't count on Airplay from my iPhone to the Apple TV because of being at the edge of my wireless connection. So I used the application to load a playlist on the Apple TV, which was always in range and connected to my stereo.

    With the 4th generation, I can't find an option to load remote a playlist, artist, album, or song. I can only handle what has been loaded using the physical remote control and a TV screen that beats my goal. I bought the 4th generation, because the 3rd generation could not access my subscription of Apple's music while the 4th generation can.

    Am I missing something or is the 4th generation Apple TV / Remote app missed something?

    Make sure that your Remote application is up-to-date. The current release is 4.2.3 and fully supports the music playback controls.

  • How to use and control the tabs?

    Sorry for such a general question, but I use Firefox with older versions of Mac OS x for years and have just been struck by this brand new and I have no idea on your tabs, "new tab page" etc. Can you just send me some documents so I can understand what they are and how to use them?

    All I see on my headers Ff are all sorts of legs that have no relevance to me, like 'how to stop Firefox from... '. "(twice), a few other symbols Ff and other"tabs"I don't know everything." All the do is filling up a bar line.

  • How can I dynamically control the sound

    Hello
    In the header part of my site, I have included a flash with sound, it plays automatically when the page is loaded, if I stop the sound in homepage, it plays the sound, when I go to another page. I want to play the sound continuously, even if the pages are loaded. How can I solve this problem?

    The problem is that the whole page reloads when you click on a button.
    My suggestion would be to frameset to load separate pages in a separate frame navigation. This should keep the music played on all pages as navigation charges ever.
    Also, I noticed that there is no way to start playing the sound again after you stop it once.

  • How Essbase treats nets of the CPU?

    Hello

    In our environment, we have the following Solaris machine:

    Computer type: T4 - 1 8 Core SPARC SUN

    CPU speed: 2 850 MHz

    UC: 1

    Cores/CPU: 8

    Total number of cores: 8

    Memory: 32 GB

    Of these resources, 3 cores are available for Essbase 11.1.2.4. As we know from the material administrator, each kernel has 8 wires, so in total for Essbase, we have 3 cores x 8 = 24 son son. And now the question is, how Essbase treats these wires? Separated from central units 'virtual '? In other words, we can for example set of CALCPARALLEL 8 in our environment, and these 8 wires will be used by Essbase (of course, assuming it's possible)?

    Thanks in advance for your prompt response.

    Rafal

    If it is SPARC T4, then you should have 8 threads by heart, calcparallel must set the number of threads to use.

    I've never heard of Bullguard, and he certainly isn't one of the
    best antivirus products.

    My guess is that you are infected with malware.

    For an anti-virus program, I recommend eSet NOD32, if you're ready
    to pay for it. If you want a free anti-virus, I recommend one (are not
    run several) of the following three:
     
    Avira AntiVir
    Avast
    Microsoft Security Essentials
     
    You also need anti-spyware software. I recommend that you download and
    (both freeware) to install MalwareBytes AntiMalware and
    SuperAntiSpyware.

    Hello

    I guess that the Toshiba Power Saver has been installed on your laptop and you use this software from Toshiba.

    If you are using Win XP and that the GST is installed, then you can check the configuration of basic settings and you might find the options to control CPU, CPU processing speed and method of cooling.

    If you are using Vista, then you should check the Vista Power Options:
    Check this thread how to manage Windows Vista power management features

    But in most cases, the cooling modules are controlled by fan that is stored in the BIOS table.

  • How to add a control to a tab

    Hello, thank you for reading my question.

    I've been wrestling with this for several hours. Just trying to change one of the examples provided in LV2014.

    1 I add a control, in the command window, a tab as the original controls as you can see on Ref [1], I added the extra and the farm AND Boolean Y & Z, tested and it works very well. This seems to work on any tab, in other words, I click on the tab I want and select a control I want a TI works fine.

    2nd I want to actually control the same appearance, see Ref [2]. I could not figure out how to copy and control the moose in the control panel user interface, but has been able to copy and paste the control into the block diagram. However, the control is not associated with the tab and is it should be a simple mater of shuffling to the active tab but not!

    Also is there some explanation why two Boolean z, that I did slip on the tab seems different than Y Boolean in the block diagram window? Is this because the Y Boolean has been customized?
