  Under the Enterprise-> Monitoring-> click the Incident Manager to go to the Incident Manager UI menu item and then click on the link ' open issues ' on the left

  Identify problems specific to your target.

  Click the problem link to view details

  On the right side, you should be able to solve the problem which will clear all Incidents related to the problem.

  or

  Go to the homepage of the target

• Clear the console through script?

  Is there a way to clean the console to Extendscript Toolkit of the currently running script?

  Thank you!

  I wonder if there is a way to clear the console from a script running.

  Ah, that would be a no. ExtendScript Toolkit isn't a scriptable application.

• public network for virtual machines, private storage and the service console?

  Hello

  So far I had a pretty small facility with 2 servers with 4 physical network adapters each running ESX 3.5, a small box of EqualLogic SAN to shared storage and a few virtual machines on our network of regular reinforcement, routed, not on a private.   The network config was really simple.  I just put everything on real IP addresses on our network of building.

  Now I want to move the SAN and the traffic on a private service console network, but I don't know how to do this.

  Right now I use 2 NETWORK cards on each server:

  vmnic0 is configured on vSwitch0 and has the network of the VM on it that all my use of VMS to talk to the outside world, and it also has the Service Console that uses Virtual Center and I use ssh to it.

  vmnic1 is configured on vSwitch1 and a VMKernel Port and also a Service Console Port for iSCSI Software to talk to my SAN.  (never been clear on why both are needed to talk to the SAN, but doctors say they are)

  My plan is to set up a vSwitch2 and bind it to vmnic2 and implemented a VMKernel Port and the Service Console Port for software iSCSI on the 10.x.x.x network, set up my new (larger) SAN box on the 10.x.x.x network and simply use Storage vMotion to move virtual machines to the new storage space.  As soon as I did this, I would like to not use the Service Console on vSwitch2 and not a Console Service at all on vSwitch0.  Is it possible to delete the one on vSwitch0 and just use a new vSwitch2 for Virtual Center and ssh access?

  So my proposed configuration would be:

  vSwitch0: VM network only, used by the VM guests for oriented public access network, no construction of Network Service Console, linked to vmnic0

  vSwitch1: superfluous once I do storage vMotion of everything on my old SAN, will eventually remove and pair vmnic 1 with vmnic0, linked to vmnic1

  vSwitch2: VMKernel and Service Console on the network 10.x.x.x, used to access the new SAN, used by Virtual Center to access the ESX, used to SSH in to ESX on private network, associated vmnic2

  If it works?

  Thank you.

  Hello

  VMkernel ports cannot live on the same subnet. So if you have 3 vmkernel ports say: vMotion, iSCSI and NFS. You really need 3 subnets. 1 for each vmkernel port.

  Otherwise how does he know all send properly?

• Why my ZTE open c Firefox OS Smartphone forget the wlan settings and does not sound the alarm?

  Sometimes it is even enough to go outside the trash to let my smartphone to forget the settings for the wireless LAN. When I come back, I have to re-enter my wlan router - not so short - code. Once the internet connection is running as it should.

  In addition, the alarm does not work, I can adjust alarms as I like, set the volume to maximum and also activate the vibrator but does nothing when the time arrived, even when the alarm appears on the screen all the time. Is my broken phone? Or is this a bug in the installation of Firefox OS?

  Where Firefox OS does not store these values for wlan connection and waking hours? Is there an internal database that may be corrupt?

• Clear the history of 'back/forward' to a pinned tab?

  Hi all

  A few years ago "delicene" posted this question (https://support.mozilla.org/en-US/questions/847382) and 'cor - el' posted a useful answer, however, Firefox has changed a lot since this was posted and I couldn't work it. Does anyone know how to achieve the same thing today.

  Thank you very much

  Chris

  That the code should still work in the Console browser (Firefox/tools > Web Developer) which replaced the error console.

  • https://developer.Mozilla.org/Tools/Browser_Console

  This will clear the history tab for all tabs and windows and not for a specific tab.
  Also data on closed tabs and windows are removed (history > recently closed Tabs/Windows section).

  See onPurgeSessionHistory in resource:///modules/sessionstore/SessionStore.jsm

  var os = Components.classes["@mozilla.org/observer-service;1"]
        .getService(Components.interfaces.nsIObserverService);
      os.notifyObservers(null, "browser:purge-session-history", "");

• Structure of the event does not clear the queue after his release from the Subvi

  OK I'm not sure if this is a stupid question or not...

  I was trying just a few tips and stumbeled on this problem...

  So I created a sample (not exactly)

  In qqq_Main.vi just press PressMe

  (it opens a Subvi qqq.vi)

  There are two buttons to stop "Alt1" and "pylone2".

  To close the Sub - VI press either on "pylone2".

  or press "Alt1", then "pylone2".

  with the latter method of the value of closing change pylone2 is registered outside the while loop and after the closure of the Subvi should not it be erased? (Or should manually clear us it?)

  For this reason not clear, the second time I press 'PressMe' change the value of pylone2 even goes off before you press anything

  I can't look at your code at the moment, but according to your description, it seems that the system works as expected. I guess you do a completely static record of events (open the event configuration dialog box and select the controls and event).

  The first thing to clarify is your use of the term "registered". In this case, it's a problem, because the registration in the context of the protests means asking to receive the event when it happens.

  Now that you know it's important to understand where the recording is happening, because that's what determines which events are stored in the queue. When you use this type of static record, registration happens from the VI the event structure is in run mode (Note: this does not mean that the VI is actually running, but just that it's the of running or reserved for the race) and the cancellation of registration only happens when the VI mode of execution. Who is right for which you get the events in the queue of the previous run of the VI - the VI is still in run mode, then the event is added to the queue and still waiting in the queue until the structure of the event to run again.

  You can work around something like that by switching to dynamic registration of events, where you can unsubscribe to empty the queue at the end of the VI, but requires more code. Also, in 2013 LV there are a few features added to events that could allow to do this statically (I don't study all the additions, so I don't know if this is possible for static recording).

  There is a good presentation on the events of NIWeek 2013 by Jack Dunaway. You can find details of how to download the video here - http://lavag.org/topic/16091-ni-week-2012-videos/

• All-in-one printer 6500: how to clear the history of calls for a 6500 printer has?

  I am upgrading to a new HP printer and want to donate my 6500 a, but need to erase history calls first.  It has been a tool to clear the fax log, but how do I clear the call history?  I checked after clearing the fax log, and all the phone numbers are always listed in the call history.

  Perhaps a better question is to know if I can reset to default, all settings the settings/history of compensation?

  It turned out that, I contacted HP by phone and received excellent help.

  There is a subset menu which can be found when you press the icon 'back'... on the icon outside the lit display that doesn't show until you type.  They had me find the appropriate page and make a "partial reset".  Brings back the printer to the page where the next time it is turned on, it will ask for questions of initial set-up and all the memory is deleted.  So I have been able to give the machine to the local women's organization helping women with no problems that I can also gave a list of contacts!  Thanks to HP for the excellent customer service!

• WebLogic Instrumentation field to start the Weblogic Console

  Hi people,

  I have a question on the instrument WebLogic domain with two groups on two servers that the application servers are instrumented when they are started from the Weblogic console (I'm not terribly familiar with Weblogic so go easy on me)

  The manual is 'almost' clear for stand-alone Weblogic Server instrumentation or using Weblogic node Manager, but does not mention anything on Weblogic instrumentation so that instrumentation is picked up when the Console is used for stop/start server

  The environment includes:

  -A server for the executed on server1 and started Weblogic domain administrator but this script:

  /bin/startWebLogic.sh

  -NodeManagers two, one on each server1 and server2, started by these scripts on each server:

  /bin/startNodeManager.sh

  -Also has two startup scripts Weblogic server on each server:

  /bin/startManagedWebLogic.sh

  /bin/start_server1.sh

  So far we've instrumented the /bin/startManagedWebLogic.sh with:
  

  QUEST_DEPLOYMENT_DIRECTORY = / foglight/Quest_Software/Foglight_Agent_Manager/agents/JavaEE
  If [f ' $QUEST_DEPLOYMENT_DIRECTORY/integrate.sh ']
  then
  QUEST_JAVA_ENV_OPTS = WEBLOGIC:SERVER
  . "$QUEST_DEPLOYMENT_DIRECTORY/integrate.sh".
  on the other
  echo agent Java EE not activated
  FI

  and instrumented the /bin/startNodeManager.sh with:

  QUEST_DEPLOYMENT_DIRECTORY = / foglight/Quest_Software/Foglight_Agent_Manager/agents/JavaEE
  If [f ' $QUEST_DEPLOYMENT_DIRECTORY/integrate.sh ']
  then
  QUEST_JAVA_ENV_OPTS = WEBLOGIC:NODEAGENT
  . "$QUEST_DEPLOYMENT_DIRECTORY/integrate.sh".
  on the other
  echo agent Java EE not activated
  FI

  This set works fine as long as the node and the server are started from the command line but it not instrument anything if they are handed over to walk through the Weblogic Console

  Issues related to the:

  -the scripts above (or all) of which have to be modified (and how) so that Weblogic Server starts instrumented to start the Console

  -what I'm missing? everything that needs to be done so that the Console is restarted with start the instrumented servers?

  Thank you

  Ovi,

  When you're setting switch servers using the console are not be started by the Manager of nodes? If they are, the instrumentation on Node Manager should do the trick. If they are NOT started using the node Manager then how they get the JVM settings?

  I saw the case in which settings for the boot server were not going through the Manager of knots, they were taken in the FMV of the options in the welogic server administration console. If you can find this place (pretty good the region where you set your memroy settins), you can manually add the flags that get the agent running.  You can see the parameters when you start weblogic from script, Xbootclasspath-... - javaagent..., you can just copy paste these lines and hardcode them into the admin console with settings java (jvm) for these servers.

  It will be useful.

• [Explanation necessary] Clears the listview data and fill it again with new data

  Hello

  I correctly filled a listview in c ++, data analysed and does interesting things with it. However, I am drunk stumbling, unable to find a way delete and repopulate my display of the list...

  Question 1:

   

  1. How can after I insert data in the list view, I clear the list data and run again the same method (init) who populated the list view with the data in the first place?

  Here are the docs that I referenced and I don't understand how to implement the methods in my code.

  QList - clear() method

  https://developer.BlackBerry.com/Cascades/reference/QList.html#clear

              //grab references
              list_view = root->findChild("listView");
  
              // set created root object as a scene
              app->setScene(root);
  
              mNetworkAccessManager = new QNetworkAccessManager(this);

  Question 2:

  How reference to the ListView object with the name "listView" in different parts of the MyApp.cpp file? Is there anything else I should add to the header file to make the accessible listView?

  Question 3:

  What happens when you call the clear() method? How the data model is affected? How the user interface is affected? What happens in memory?

  Question 4:

  How do you verify that the data in the list has been deleted so that you can go ahead and fills again with new data? What is the cheque that I perform?

  I would also like to know how you manage multiple views of lists and data sources in your applications. Best practices or ideas?

  Thank you
  

  I was able to clear the listview with the following code, if anyone is interested.

  listView.dataModel = null
  

  The dataModel must be set to "null".

  So there is clearly no problem on the side of Nexenta.

  What I am doing wrong?

  Is there a problem with this build exakt?

• Dashboard of the alarms to expire

  Hi all

  Anyone had a similar experience? Our dashboard alarms even expires when the time range is set to the last 4 hours and the County of alarm value 100. I know we have a lot of alarms, but I don't mean to get all the alarms. It's bad Foglight reputation within our society, I don't like people to think that Foglight is slow.

  Then I looked at the definition of dashboard and found the question is an WCF application called something like alarms alarm/Histocal. When I tested this application, it also has expired. BTW, our timeout value is 60 sec which is fine, I don't want to wait more than 60 seconds to see my alarms.

  We are always on FMS 5.5.5, do not know if the dashboard of the alarms were improvements in newer versions. I just wanted to ask if they are facing the same question to the community.

  Because it aims to tell the people to do their troubleshooting in Foglight, I decided to make my own dash of the alarms based on the AlarmService API and a few days later, I got it to work and it has a filter too. Without using this request of WCF, my dashboard of alarms is very fast, it takes seconds.

  Quest will improve the performance of these dashboards? I remember that I had to modify the dashboard failure because there was too much delay.

  Sorry for the long post.

  Yes, the performance of the dashboard alarms has been significantly improved in the FMS 5.5.8. You will see the best dashboard performance and many new features and improved when you upgrade to version 5.6.

  Kind regards

• Installation Partition problem (allocated too expensive for the Service Console?)

  Installation Partition problem (allocated too expensive for the Service Console?)

  RAID1 (15K 146 GB SAS) on Dell R710 and VMFS is on table EQL.

  What I did during the ESX4.1 excavation, it's that I have used ALL the space in 146 GB (mainly for / and / var), after adding this ESX host to vCenter, VC and EQL ASM/VE started to complain about the following points:

  1 VC: health check of localstorage warning (only has 245 MB left on 146SAS localstorage)

  2 EQL ASM/VE: warning rootFolder folder (due to the above)

  I thought that he is authorized to use all the space for / (50 GB) and / var (50 GB) in my case for only 146 GB, I don't think I need to leave any space on the installation disc.

  Could someone share some lights here?

  Thank you

  As you can see SDS use all the SDC VMFS partition space.

  This create the alarm.

  The thing really confused me why I have to leave a space on the disk at all?

  Technically there is no reason to let the space... but also no reason to have a big service console

  Usually, you need 10 to 20% free space for each snapshot data store and Exchange files... but in your case, you will not have these files.

  If you have any problems, but you receive the alarm until you do not disable them on this specific data store.

  PS: I suggest you switch to ESXi, is quite simple and it doesn't have this strange vmdk for the "console".
