• Need help with NetImageTracker/Manager

  Hi all

  I need help to understand how NetImageTracker works. What I want to achieve is to download the images into listview, but I'm trying to use it directly from C++. What I have right now is declaring a new ImageTracker Net and then I use the function imageSource, but for some reason I can't pass my url in there.

  So I have

  NetImageTracker* nit = new NetImageTracker();
  
  nit->setImageSource(QUrl(feed.value("url")));
  

  but I don't think that the way it was suppose to work. the feed.value ("url") is a json file I upload to the web

  Thank you for the help

  You will need create a NetImageManager instance which will use all the NetImageTrackers:

  To all:

  NetImageManager * manager_;

  In the constructor:

  manager_ = new NetImageManager (this);

  When to create ImageTrackers also put their parents so they will be automatically destroyed as well as parent:

  NetImageTracker * nit = new NetImageTracker (this);
  or
  NetImageTracker * nit = new NetImageTracker (manager_); If you want to define manager_ as parent

  Configure ImageTrackers with instance of NetImageManager:

  nit-> setManager (manager_);

  Set the URL of the image to load: (use setSource, not setImageSource because it contains the result)

  nit-> setSource (QUrl (urlString));

  Connect to the imageSourceChanged signal and when it starts to get the URL of the uploaded image.

  In the signal handler:

  NetImageTracker * Tracker = (NetImageTracker *) sender();

  QString urlStr = Tracker-> getImageSource();

  QUrl url = QUrl (urlStr);

  This url can be used in ImageView

  Tracker-> deleteLater(); possibly destroy NewImageTracker because it is no longer necessary

• Need help network!

  We are a House of Apple? 2 iMac, MacBook 2, 1 MacBook Pro, iPhone 4. I have an AirPort Extreme and an airport express Network Extender. At one point, some of our phones or computers cannot access Internet. See the router, they are unable to open a session. I'm not an irritable Apple. I did reset hard in AirPort Extreme. I tried a number of things, but the problem seems to be growing.

  My equipment is:

  iMac 21.5 "end 2013

  3.1 GHz Intel Core i7

  OS X 10.9.5

  iMac 21.5 "end 2011

  3.06 GHz Intel Core 2 Duo

  OS X 10.6.8

  iPhone 6 +.

  iOS 9.3.1

  iPhone 6 s

  iOS 9.3.1

  iPhone 6 s

  iOS 8.4.1 (update needed)

  iPhone 5 s

  iOS 9.3.1

  All components see the router but will not have Internet access. Sometimes I get a message on an iMac that says, "another device uses this IP address. Try again later or change IP addresses. ". I have also a message that indicates the IP address is assigned manually. I have never manually assign an IP address. I could really use some help here. Don't forget, you talk with the novice.

  You have not thought about it, but the "modem" which provided you your provider of Internet Service (ISP) may be the culprit. This is because it is quite common for ISPS to limit the number of devices that can connect to the Internet in a given "modem".  A common limit is 5-6 devices.

  Is is possible to communicate with people of support at your ISP to ask them...

  (1) is there a limit of 6 to 8 devices on the modem they received for you?

  (2) if so, ISP support people can change this limitation to allow more devices to connect... Ideally, at no additional cost to you?

  Looks like you probably need at least 15-20 connections available... one for each device and 4-5 extra to help prevent conflicts.

  If you could provide the number of brand and model of the device that you call your "modem", let's get a setup guide or manual to learn more about the features of the device.

  My Lab Top is runing slow

  Hello

  Slow is a relative term, if you can put some number (or a more detailed description, it might help you.

  Associated with the network several times slower are a result of viruses and malware that got into the shape of the Internet System.
  Carefully analyze the computer and clean it from the 'Junk.

• Need help with Photo Manager

  Cannot find pictures on microsoft office manager. Do the steps which have been called for and still can't find the program. Information on the microsoft Web site says to click the office program and should be able to get her there – no results.

  If Picture Manager is installed on your system, you can run it by going to start / run
  and type or copy / paste > OIS.exe

• Need help from Picture Manager! My pictures keep replicating & have 100 to 150 copies. When I try to delete, they are continuing to replicate.

  Have tried and tried to remove duplicates. Nothing works!

  Have tried and tried to remove duplicates. Nothing works!

  =============================
  Unwanted copies have file names with
  copy "prefix of"?

  Example: Copy of IMG_1455.JPG

  If_yes_maybe the following tutorial, I wrote
  for XP offers a few ideas:

  Here's how to reproduce the unwanted
  copy of...

  Hold down your CTRL key and select multiple files...

  Place your pointer over the selected group
  (holding the key ctrl) and left click / drag
  the group even just the slightest bit... now
  release the mouse button.

  Maybe the following will help:

  Sometimes most of the person who
  trying to select multiple by holding the CTRL
  or the SHIFT key down while clicking on the left to select the
  image files.

  Copies are created when you are unable to
  completely release the mouse button before
  you move the pointer to another file. When a group
  the selected file is dragged... even the slightest
  release the mouse button will produce a bit...
  copies of all the files previously highlighted.

  It's a little easier if you have your folder
  Options set at single click... that way you can
  select/deselect a file with just a mouse more
  and you don't have to click. For multiples you
  I have to keep... CTRL or Shift.

  Do not click on... no slip... no copy... maybe that of
  your solution. To adjust the click...
  Open a folder and go... Tools / folder
  Options / General tab... Check... 'single click '.
  To open an item"/ apply / OK.

  If you want to delete all the files in a folder
  You can try the following:

  Reach... Edition / select all... or type... CTRL / has...

  With all of the files selected... go... Drop / delete...
  or press your delete key... or... click on the
  Group and choose 'delete '.

  How do I find and remove unwanted 'copies '.
  of your image files.

  Open the folder that the images are saved in and
  on the left, click on the button 'Search' in your toolbar.

  (If you view the files from a montage
  program and do not know where the record is... right
  Click on one of the image files and the menu...
  choose... Properties. The path to the folder will be
  in the tab 'General' to 'Place').

  In the research pane select... "All files and folders".

  In the "All or part of the file name" field. Come in...

  a copy of

  Now... on the left, click on the search"" button.

  When the search is complete... go to... Edition / select all...

  Then go to... Remove / delete.

  You will see a dialog box asking if you are sure
  you want to delete the files, click Yes.

  Now... on the left, click on the 'Back' button in your toolbar.

  Now the remaining files should be your originals.

  If you delete the wrong files... recover from
  your basket now.

• Lab Manager acceleration kits / required licenses?

  Hello!

  We are currently using ESXi and plan to move to centralized test Lab Manager lab. The estimates are based on the acceleration kit that used to be available at about 4-5 k €, which seemed to include VI 3 licenses that are required for the Lab Manager to run on top of ESXi (or if whatever the basis ESXi does not support).

  Now I can't find the acceleration kits more 'Buy Lab Manager', instead I find licenses for Lab Manager only.

  Now I read everywhere that the vCenter is necessary and even messages that describe that vCenter foundation is not sufficient to run the laboratory Manager. However no official 'that's what you need to do if you want to get Lab Manager' running.

  To be honest, if the acceleration kits were gone for good, licensing begins to be as clear as some States large company in their regulatory policy, "must be this version of the database server", but do not worry to mention what license you need for the said server or background Windows server...

  I would like to know the price of 'minimum' (to continue) Lab Manager on top of bare metal, start-up costs and maintenance renewals when the initial support runs.

  With regard to reading, 2 or 4 processors as it seems to count.

  BR,

  Kalle

  Sorry, that seems so difficult.  To sort through all of this:

  • Lab Manager requires ESX Standard or Enterprise.  It does not currently run on ESXi, but it's on the Roadmap (cannot discuss dates here).

  • Lab Manager 3 requires vCenter (Lab Manager 2 does not work).

  • vCenter Foundation is untested, but should work (but can only manage up to 3 knots).

  • ESX Foundation is not supported by the Lab Manager.

  • The laboratory director is authorized by the node (the server Lab Manager is free).

  • Lab Manager Server runs on Windows Server 2003 and can run on a virtual machine

  • VirtualCenter runs on Windows 2000, Windows XP Professional, or Windows Server 2003 and can also run on a virtual machine.

  Thus, the minimum subscription is:

  • ESX Standard for two processors

  • Lab Manager for two processors

  • vCenter Foundation

  • Windows licenses you need for the Lab Manager server and VirtualCenter Management Server.

  Installing vCenter Management Server and server Lab Manager on the two virtual machines on this host ESX and use their local drive to store the virtual computer images.

  Such a system doesn't scale well, of course.  When you size, you will need to add the following:

  • Shared storage (NFS, iSCSI, or FC)

  • More ESX and Lab Manager licenses

  • vCenter Standard or Premium, instead of Foundation.

  Hope this helps,

  Steven

• Storage for Lab Manager

  My client needs storage for Lab Manager running on 100 servers. Is it recommended to use the NAS or SAN for Lab Manager running and what type of e/s that you wait for the same thing?

  I did a little bit with storage of LM in recent years.

  I have a development/test environment on LM 600 machine, using 2 Sun 7210 storage devices (is no longer available) on NFS shares. We have 2 links 1 G servile vmKernel traffc as well as links to more vmnetwork, management, etc.  The devices are related to links of 4 x 1 G each.

  I don't know what are the current constraints of LM/ESX, but whenever we revisit the decision 'block vs NAS' we end up selecting NFS (our Sun boxes can present the iSCSI as easily).

  As Jon says, what storage you need certainly depend on your VMS and load.  NOTE: my experience is * NOT * in a production environment, where I am squeezing virtual machines performance.  It's more about the functionality and "adequate" performance (where "adequate" is a measure based on the user experience topic).

  Some things we have learned over the years:

  • IOPS / s are kings, and most of them are entries.  (Written at the moment, I have a few heavy ready operations push me down to about 65 percent.)  I saw > 80% of entries maintained for days.)
  • Latency does not seem as important - VMs run about the same at 10ms latency and latency 250ms NFS NFS.  When latencies above 750ms grows, they will be noticiable users and if they go more than a second over 1000 ms you will begin to see the impact on the guest OSes, especially Solaris x 86.
  • Normal operations don't care about bandwidth - just current execution machines don't even fill a link 1 G
  • Deployment operations * could * start filling to the top of the bandwidth, maybe
  • Betware storm IO.  Often people think the storm IO deployment/boot, but 400 RedHat machines all the kickoff of their 'updatedb' cron job at 04:00 can produce any IO storm as well.  NOTE: IMHO if you buy storage to handle this kind of thing, you're overpaying storage.  I've spread my cron through the night and now can not see on the graphs of storage performance.
  • There is * NOT * a good correlation between guest OS IOPS / s as shown, for example, iostat and PAHO are / s NFS presented to the storage system.  I'm guessing that ESX made a lot of caching.

  Most storage vendors I spoke last year does not seem to find it.  They think in terms of bandwdith and it accelerates with read cache, so unimportant in my environment - I had to push really hard to get sellers to think in the right conditions and some of them really seem out of their depth there.

  I think that this state of mind is important: consider the IOPS / s as you consider CPU: how much should I give to each machine?  How much should I oversubsubscribe?

  Like CPU, a physical machine which IO a lot more available that he needs and you can consolidate - but don't know how.  A physical machine with a pair of 15 k drives RAID1 has about 200 IOPS / s available and readers spend most of time inactive (a bit like the CPU).

  That will boost the machines and when?  Right now I'm on average 9 inputs/outputs by VM, which in my opinion is quite small.  My storage system can go higher under request, but I have enough machines that it is fairly constant.

  In my quest for the perfect storage of LM, I found the usual: good, not expensive or fast, you can choose any two.  How we use LM (lots and lots of shared models) we would really like a unique namespace shared (i.e. 1 data store). I have yet to find the 'perfect' - storage, the Suns are very profitable for the performance and space, but their management takes too much of my time and my 72XX are not expandable - the 74 might be a different experience.  I am currently looking to add some SSD storage, but the ideal configuration would be automated migratino between levels (for example, EMC QUICKLY) and if I bought only from EMC I would triple my cost per VM.

  I talked to people who have a pattern of use of different models that are quite happy on several data stores.  If you can move your load through many warehouses of data then Isilon looks like interesting storage.

  So, in summary:

  • Watch IOPS / s 1st, 2nd and 3rd, then the latency time, then (maybe) bandwidth
  • Manage the budget or the ability of the IOPS / s as you CPU
  • You may not use comments IOPS / s to provide shared storage IOPS / s

  I'm hoping to have a better storage solution in the next 6 months or more.

• Lab Manager V3 and a second NETWORK card

  Hello everyone. I have a question I hope you can help me with. In Lab Manager V2.5, we were having a problem with fencing. Our fencing required 5 IPs and our customer wants about 100 fences. As we seek to do not use more than 2 C all classes of IP addresses, we hoped an alternative solution.

  Our current idea is to try to use the second NETWORK card on a separate internal switch. This option would use the internal IP for 4 IP addresses and an external IP address. Although this plan seems feasible in theory, the V2.5 Lab Manager did not work to achieve this end. Thus, we are now experiencing V3. Does anyone know if this plan of attack is feasible? If so, what measures are necessary to achieve this goal? The second NETWORK card will be detected automatically by the Lab Manager, or is there a configuration I do not see any there to achieve?

  In short, I need to know if a second NETWORK adapter is feasible with V3 before submitting a request for a second switch. Please let me know if anyone has any info on this subject. Thank you kindly.

  LM 3.0 allows to use up to 4 network LM by VM Interfaces.  A Network Interface is the combination of the virtual NETWORK card and a physical interface LM LM 3.0, or virtual network.  Networking has been considerably strengthened LM 2.5 days.  Instead of a comprehensive physical network, you can have several (limit)? Physical networks that map to vSwitches in your vCenter/ESX host environment.  The Act of creating a physical network of LM 3.0 creates a group of ports on the vSwitch that you you mapped physical network LM.  Each physical network can accommodate up to worth (1024) 4 c of static IP addresses.  If you want that your different physical networks LM using different physical network interface cards on the ESX host, map to different vCenter/ESX vSwitches.

  Fencing is also managed a little more dynamically without the limitations in number of closed configs that were in previous versions.  All virtual machines in a fenced config needs to be hosted on the same ESX host however.

  Oh, virtual networks are a separate issue, which allow the installation of a local network visible only to virtual machines in a configuration.

  I hope this helps.

• Need help to understand the network of vSphere environment

  Hello

  I need your help in understanding the network environment in vSphere. Please see the diagram and the text below:

  

  NIC #1 - Management Port (access from client vsphere, vCenter server)

  NIC #2 - Port of VMkernal (for iSCSI, vMotion, etc.)

  NIC #3 -?

  #4 – CARTE NETWORK INTERFACE?

  Q1 how allow external users to access services over the ESX host? (for example, IIS, FTP, Exchange, NFS)

  Q2, what will be the role of the other two network cards? Is it connected to the physical switch?

  * Ask you all to please help me by sharing your knowledge / experience on the network portion, you have made in your environment as NIC how, what to do with that. *

  I really need to understand the networking of concepts in vSphere, hope that your help!

  
  

  Best regards: Yash

  With an additional NIC with 2 port a general configuration might look like this:

  vSwitch0 - vmnic0, vmnic1 (connected to different physical switches)

  Network VMkernel management

  VMotion VMkernel network (own IP network, own VLAN)

  Better if they is configured as active / standby.

  vSwitch1 - vmnic2, vmnic3 (connected to different physical switches)

  Trade VM

  vSwitch2 - vmnic4, vmnic5 (connected to different physical switches)

  VMkernel iSCSI (own IP network, own VLAN)

  Ideal if it is added to the component Multipath iSCSI, which is quite easy to vSphere 5.
