Question about work load alerts

vCOPs has been running in our environment for 10 months and more. So far it has been used more for critical alerts that analysis. We are trying to get a deeper understanding.

5.8.1 running

I read the following messages, but am still a little foggy on why we see what we see.

https://communities.VMware.com/message/2396460#2396460

https://communities.VMware.com/thread/449924

We receive alerts alert network that demand is to reach 100% of the available resources.

New alert Type: health, Sub-Type: workload, State: immediate, kind: HostSystem

The application of the object: info is 100% capacity of available resource. Network is a limited resource.
Alert type: health
The attention of subtype: workload
Alert: immediate
Resource type: HostSystem

We receive as critical network warns that demand 100% of available resources.

Nalert Type ew: health, Sub-Type: workload, State: criticism, genre: HostSystem,
The application of the object: info is 100% capacity of available resource. Network is a limited resource.
Alert type: health
The attention of subtype: workload
Alert: critical

If you look at the attached doc you can see actual usage during the alarm time is about 55% of the capacity and actual use during the critical alert is about 77% of the capacity.

If the alerts are not an indication of actual use of NIC I'm not sure what we say the alerts.

Any help would be appreciated.

This network IO bar there is just the last collected metrics. You need to appear a metric chart, where draw you the overall badge | the workload for this host, as well as individual workloads of cpu/mem/disk/network. Look back the past 24 hours or 7 days... and you will see them fortification (vC Ops is not incorrect to say that you are 100 > 90). It is these spikes that can cause alerts. One option would be that you could reduce the alert for infrastructure. workload in config policy to not notify you when this product (alert system host workload). Or instead to drop quite alert, simply set the levels of warning/immediate not getting attention, the critical value to 100 and see what is happening (for the badge of infrastructure workload changes). However, probably if you let this long race, vC Ops will learn the maxObserved of the NIC and conditioned as well higher watermark beyond your normal percentage of 80/90/95 levels.

For CAP / etc, you can ignore the e/s disk and network i/o, but not the case with the calculations of badge of health.  If you need to exclude individual components of the overall workload of a vSphere resource calculation, the only way is to stop the alerts on the overall badge "charge" and alert on the parameters of work of children... e.g. cpu | workload, mem | workload, etc.

A lot of options... Try them and see what works best for you.

    (3) can we ignore this alert?

    Hi Lee,.

    If the State of health of the device then changes to a stranger in the status survey OME automatically generates this alert to say that the health of the device has changed.

    If you don't want to see these alerts, you can disable this alert settings option in the preferences. Uncheck the box enable internal health alerts and you will not see these alerts.

  • Satellite L650-11R - a few questions about this

    Hello there :-)

    I have a few questions about my new L650.

    I've never had Toshiba notebook before so I apologize if some of these "quirks" are actually quite normal on this laptop. I really want to hear the views of other users L650.

    1)
    First of all, by the time I turned it on I saw gradient thin (1-2 mm) along the right edge of the screen that goes from the bottom up. Maybe "degraded" isn't the right word, but it seems that since two or three pixels are kind of discoloration or lose brightness/sharpness to the edge along the straight bezel. It is not really that visible, looks like the colors are desaturated a bit here or brightness is a bit lacking. He can be seen everywhere (bios or no color in Windows, but better in the lighter background).
    The left side (or other) seems ok, all this along the right edge is somewhat suspicious. If one can compare? I don't know if it's something to worry about or is just supposed to be like that.

    2)
    The other thing I noticed heating of the processor (Intel i3 330M) and GPU (ATi Mobility Radeon 5650). It's pretty hot here right now (I would say that the temperature is around 28 degrees Celsius when using cell phones). He is sitting on the hard surface (table) and nothing is blocking the vents.
    However, at "rest" (surf the web & regular light stuff), average CPU temp hovers around 58 ° C. It usually goes from 45 to 62 in just a few minutes after starting, and then I can hear and see (Toshiba PC Health Monitor) evacuate the kicks in. Temp goes back to 50 +, event stops and then the temp rises to 60 + until the vent is used again.
    During load full (Prime95 or some games), CPU is going all the way up to 75 degrees (the highest being 77). Fan runs at 75 to 77% during this time, never go faster.

    GPU idling is usually around 5 degrees above temp CPU (62-65). During full load (for example. Benchmark of Far Cry 2), I see a lot of stuttering with the latest drivers Catalyst and DX10 (not sure if the stuttering has something to do with heat), otherwise it is ok (no artifacts or anything like that). Temp of GPU during the loading goes up to 74-75, fan speed is locked at 30%, the frequency of the heart 5650 is 450 MHz. left side of the laptop (vent and below) is pretty hot, while the keyboard is warm (or slightly warmer who who).

    These time seems correct and safe in the long term? I'd rather events works all the time (they aren't really very strong) and keeping time less than 50, but there are just wishful pious bios control events and I can't control not the bios. :-)

    3)
    This is just General related products. :-)
    Official specifications of Toshiba L650 say ATi 5650 (between other low range GPU), but I saw a few specifications calling for there 5730 (same model 11R). Is there really a Satellite L650 with ATi 5730 GPU models?

    Sorry for the long post, I tried to include the best possible description that I could do. :-)

    Thank you in advance.

    Thanks for the additional info!

  • Question about the charging light on the venue Pro 11 (5130)

    I'm curious... read these discussions in recent weeks... found this work with the Tablet for about 2.5 hours after... I was up to 75% of battery. Connect the tablet to install a software... noticed 75%, not charging. Stop... removed the battery and put it back... He then read 75%, in charge. OK... so what's fixed now... a question about the manual of the system. Said that when the battery is charging, a white light is supposed to be on... where? When that I start, I see a momentary white light at the top of the screen, by the front camera... but when it is plugged and the loading and off... white light no.... No a - I misread? Thank you

    Light (color is white when the load) is located next to the power switch (top, right). Mine re-load very fast.

    White light goes off (or does not) when the Tablet is fully charged (the light on the charger is always on when it is plugged into the outlet)...

  • Questions about discussions...

    Hello

    I have a new app to do that requires network access.

    I have read this EXCELLENT post from peter_strange:

    http://supportforums.BlackBerry.com/T5/Java-development/connecting-your-BlackBerry-http-and-socket-c...

    Because I can't use BIS - B because I'm not a partner of the Alliance, I wanted to take a look at the new OS 5.0 network API and see how it works.

    I know that network connections should be performed in a separate thread.

    I'm far from being an experienced Blackberry developer... so I have a few questions about discussions.  I looked around the Internet, read on the forum, read the documentation, did some tests and so far, I came up with this code:

    SerializableAttribute public class HTTPConnection extends UiApplication {}
    Public Shared Sub main (String [] args) {}
    HTTPConnection PAP = new HTTPConnection();
    theApp.enterEventDispatcher ();
    }

    public HTTPConnection() {}

    }
    }

    class HTTPConnectionScreen extends form {}

    ' Public Sub fieldChanged (field field, int context) {}
    ConnectionThread ct = new ConnectionThread (rbGroup.getSelectedIndex () + 1);
    CT. Start();
    }
    };
             
    ButtonField buttonField = new ButtonField ("Connect", ButtonField.CONSUME_CLICK);
    buttonField.setChangeListener (listener);
    Add (buttonField);
    }

    / * method of onSavePrompt override default to avoid being asked if I want to record every time * /.
    protected boolean onSavePrompt() {}
    Returns true;
    }
    }

    class ConnectionThread extends Thread {}
    private int transportType;
    public ConnectionThread (int n) {}
    transportType = tt;
    }
        
    public void run() {}
    ConnectionFactory connFact = new ConnectionFactory();
    ConnectionDescriptor connDesc = connFact.getConnection ("URL", transportType, null);
    If (connDesc! = null) {}
    try {}
    HttpConnection httpConn = (HttpConnection) connDesc.getConnection ();
    httpConn.setRequestMethod (HttpConnection.POST);
    httpConn.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");

    Dialog.Alert ("- SUCCESSFUL CONNECTION-");
    }

    }
    If (httpConn! = null) httpConn.close ();

    System.Err.println ("IOException Caught:" + e.getMessage ());
    }
    }
    }
    }

    In fact, this code works very well... but I want to improve it, and I have a few questions:

    1. I think that right now, every time I click on the 'Connect' button, I start a new thread. I would like to end this thread in the "run" method, but I don't really know how to access the variable 'ct' from there.   Counsel on how to do it?  Or maybe always use the same thread until my application is closed?

    2. in the FieldChangeListener of my "Submit" button, I want to access the value of radio box.  I did work, but I had to do my 'final' variable  What is the right way to do it?

    3 - to display a dialog box with 'Successful connection', I just wanted to write something in my main screen.  How I do that?

    I'm just a bit confused as to just what set up when you use a separate thread.

    Thanks for your advice!

    Edit: Hidden URL I connect to...

    That's what I call a good question! (now I'm wondering why the forums do not work with opera correctly, in any case, here my baldy to the answer format): 1. your thread "dies" when it's over, no need to close it. 2 Yes 3.

  • EBS 12.1.3: a few questions about cloning

    Hello

    We have EBS 12.1.3 on AIX 7.1.

    A few questions about the cloning of level shared environment of application layer non-shared application environment. We followed 'Cloning Oracle Applications V12 with rapid Clone [ID 406982.1]'

    Environment (shared application layer) source:
    -Two nodes in the active application and LBS
    -A database of active and a passive database configuration with Oracle Data Guard.
    -Terminate SSL at the load balancer
    -Updated CFP implementation

    Environment target (level app not shared):
    -A single node of the application active
    -One data node active
    -Without SSL
    -No PCP

    After the cloning was completed, we noticed the following problems in the target system:

    (1) home page is not available because application $CONTEXT_FILE layer always contains the endpoint "https" and ssl settings.

    Workaround solution:

    Change (with text editor) layer Application $CONTEXT_FILE as follows.
    < webentryurlprotocol oa_var = "s_webentryurlprotocol" custom = "yes" > http < / webentryurlprotocol >
    < sslterminator oa_var = "s_enable_sslterminator" > # < / sslterminator >
    < login_page = "s_login_page" custom = 'yes' oa_var > http://myhost.mydomain.com:8000/OA_HTML/AppsLogin < / login_page >
    < externURL oa_var = "s_external_url" custom = "yes" > http://myhost.mydomain.com:8000 < / externURL >

    Run the automatic configuration service and application layer.

    Is there a better solution and supported for this?

    (2) simultaneous managers do not work properly, because they still have old names of node (used in the CFP in the source system). The solution is used:

    1. connect to the EBS GUI web and delete all nodes of all concurrent managers.
    2 shutdown application layer. Check that all concurrent managers have been extinguished. If not, kill the process manually
    3. as a user apps run cmclean.sql
    4 restart the application layer

    Is there a better solution for this?

    (3) database ARCHIVELOG mode nonarchivelog mode changes in the target system. Is anyway to prevent this?

    (4) in addition, we would like to make a full clone (app + db levels) of production without closing the application. Is this possible? What would be the best documents to describe it? In Production, we have Oracle Data Guard physical standby installation as per "Note technique Oracle: Business Continuity for Oracle E-Business release 12 Using Oracle 11g Physical Standby Database [1070033.1 ID]. This can be used when executing a clone of warm for the database, right? What application layer? The steps in 406982.1 include AutoConfig in what application level should be running down. Must the application be broken when running "to maintain the Snapshot information?"

    (5) one last question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. For example, https://myhost.mydomain.com:5501 / em gives "cannot display the Page. It was working properly last week. In Firefox, the same link works fine. Any ideas how to solve this problem?

    Thanks for your replies in advance.

    BR,
    TH

    (1) home page is not available because application $CONTEXT_FILE layer always contains the endpoint "https" and ssl settings.

    Workaround solution:

    Change (with text editor) layer Application $CONTEXT_FILE as follows.
    http
    #
    http://myhost.mydomain.com:8000/OA_HTML/AppsLogin
    http://myhost.mydomain.com:8000

    Run the automatic configuration service and application layer.

    Is there a better solution and supported for this?

    No, you must modify the context manually and run the automatic configuration.

    (2) simultaneous managers do not work properly, because they still have old names of node (used in the CFP in the source system). The solution is used:

    1. connect to the EBS GUI web and delete all nodes of all concurrent managers.
    2 shutdown application layer. Check that all concurrent managers have been extinguished. If not, kill the process manually
    3. as a user apps run cmclean.sql
    4 restart the application layer

    Is there a better solution for this?

    You follow the best approach. You could update the details of the server node if you wish.

    (3) database ARCHIVELOG mode nonarchivelog mode changes in the target system. Is anyway to prevent this?

    By default, the quick Clone will create the target in noarchivelog mode database.

    (4) in addition, we would like to make a full clone (app + db levels) of production without closing the application. Is this possible? What would be the best documents to describe it? In Production, we have Oracle Data Guard physical standby installation as per "Note technique Oracle: Business Continuity for Oracle E-Business release 12 Using Oracle 11g Physical Standby Database [1070033.1 ID]. This can be used when executing a clone of warm for the database, right?

    Fix.

    What application layer? The steps in 406982.1 include AutoConfig in what application level should be running down. Must the application be broken when running "to maintain the Snapshot information?"

    You can copy the files from the application tier node, while demand is rising. And, there is no need to stop the application to run "to maintain the Snapshot information."

    (5) one last question (not related to cloning). Oracle Enterprise Manager console webUI has recently stopped working in IE8. For example, https://myhost.mydomain.com:5501 / em gives "cannot display the Page. It was working properly last week. In Firefox, the same link works fine. Any ideas how to solve this problem?

    If it works from a browser, then it should not be a problem of EM. Have you tried another client and see if it works? Have you changed a setting in your Internet Explorer browser? Please make sure you add the URL of the EM to the list of trusted sites.

    Thank you

  • Questions about the installation of ColdFusion 9.0.2 version of existing in version 9.0.1

    Hello

    I'm currently running ColdFusion 9.0.1 enterprise edition and plan to upgrade to version 9.0.2 version. I understand that this requires uninstalling existing 9.0.1 and perform a new installation of version 9.0.2 version. My concerns are below:

    1. for the installation of the 9.0.2 version the 9.0.2 installer (demo / trial version) must be downloaded and the existing serial number (used in version 9.0.1) can be given during installation to convert it in fully registered mode - please correct me if my interpretation is incorrect here. My question is will the existing serial key (as shown in the page Admin of CF 9.0.1 version version) work with the 9.0.2 version as well?

    2. There are many features that are present in the current 9.0.1 version - for example the sources of data configured in the Admin see Y page there a way I can save these configurations of the existing version and to migrate settings to the new 9.0.2 install, or what I have to do the entire configuration manually after the installation of new? Data sources is something I can think; What other configurations can I save, if such a provision is available?

    3. in the installation of the 9.0.2 version there is a question about "configure the Web server for CF Connector" allows me to add Web/sites Internet servers during installation. If I select "built-in Web server" as the option (so do not configure any Web-site Web server), can I change this and configure Server/site later, after compeleting installation?

    What would be the things I need to be careful during this installation to version 9.0.2 from 9.0.1?

    Thank you!

    Arun-

    I did a successful version 9.0.2; installation answering my own questions, for the benefit of future development-

    1. Yes. Only the serial number is required (as shown in the Page of the CF Admin of existing facility)

    2 configurations (for example: data sources) can be exported. Go to CF Admin Page, click on packaging & deployment, click on Archives of CF. Basically, you export settings as files with the extension archive. car. Once exported from the current installation, it can be imported by clicking on the button deploying car file.

    3 server configuration can be modified (Add/Remove) by using the "Web Server Configuration Tool" which is installed by default with CF 9. You can find it under program files (windows OS).

    I had some problems during the installation. After installation, the CF Admin page would not be made. Virtually no cfm page don't take charge, because the extension is not known by the IIS (or the server you are using). To set this up, use the "Web Server Config Tool" mentioned above. This launch and activate the check box that is on the rendering cfm pages (forgot the exact name). Once this is done, cfm pages must load. I had to enable this and then do a reinstall but.

  • A few questions about integration between POET and EBS

    Hi you
    I am a new bie BIEE. In those days, have a look at the POET architecture and BIEE components. In the next project, there is some work on the development of POET based on request of the EBS. I have a few questions about integration:

    (1) generally, the POET application and database server is decentralized with application and database EBS? Both BIEE 10g and 11g version can be integrated with EBS R12?

    (2) in the POET administration tool, the first step is to create arrays of physics. If the source application is EBS, is it still necessary to create the physical tables?

    (3) if the physical creation of tables is needed, how to transfer data from the source of BSE BIEE physical tables tables? What ETL tool is preferred for most of developers? generator for warehouse or Oracle data integration?

    (4) during the data transfer phase, there are many many large data to transfer, how to keep the entire? for example, it must transfer 1 million lines of source to physical tables BIEE database, when 50% is completed, users try to open the POET report, they can see the new data of 50% on the reports? is there some transaction in phase control ETL?

    could someone give some pointers for me? I am very appreciated if you can also provide any other information.

    Thanks in advance.

    (1) generally, the POET application and database server is decentralized with application and database EBS? Both BIEE 10g and 11g version can be integrated with EBS R12?

    You shud look at OBI request here that uses OBIEE as a tool for reporting with pre-built modules. 10g & 11g comes with different versions of the applications of BI that supports sources such as Siebel CRM, EBS, Peoplesoft, JD Edwards, etc...

    (2) in the POET administration tool, the first step is to create arrays of physics. If the source application is EBS, is it still necessary to create the physical tables?

    His independent of any source. It comes to OBIEE modeling to create the RPD with all the layers. If you build from scratch, then you will need to create all layers else if BI Apps is used so you can get pre-built RPD and other pre-designed components.

    (3) if the physical creation of tables is needed, how to transfer data from the source of BSE BIEE physical tables tables? What ETL tool is preferred for most of developers? generator for warehouse or Oracle data integration?

    BI apps comes with ETL pre-built mapping to use with the tools majorly with Informatica. Only applications BI 7.9.5.2 comes with ODI, but oracle has the intention of having only ODI for any other versions.

    (4) during the data transfer phase, there are many many large data to transfer, how to keep the entire? for example, it must transfer 1 million lines of source to physical tables BIEE database, when 50% is completed, users try to open the POET report, they can see the new data of 50% on the reports? is there some transaction in phase control ETL?

    User will see still old data because its good enable Cache and serving it after each load.

    See http://www.oracle.com/us/solutions/ent-performance-bi/bi-applications-066544.html...
    and a lot more docs on google

    Hope this helps

  • Question about DISCHARGE (expr, 1016) function

    Hello

    I have a question about the DUMP function, specifically the DUMP (expr, 1016). What character set is the function of report? The only logical answer seems to me the characters of data. The http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions055.htm#SQLRF00635 docs it says: "by default, the return value contains no character set information. To retrieve the name of character of expr, add 1000 to all the values of previous format. "For example, a return_fmt of 1008 returns the result in octal * and provides the character set name of expr.*.

    I ask this question because a client complains that there a database with database EE8MSWIN1250 (obtained from DATABASE_PROPERTIES) characters and when I asked him to run a SELECT that could empty the contents of a column, he gave me this result:
    select dump(some_col, 1016) from some_table;

    Now I can't imagine how the data can be stored in the AL32UTF8 character set if the characters of the database are EE8MSWIN1250. This scenario is still possible? I tried in vain to reproduce on my test database.

    I don't know if the column is defined with the characters of database or the national database characterset, but even if it was a NVARCHAR2, the dump function could not return AL32UTF8 since he is not a national character set.

    If anyone has an explanation, I will be very grateful.

    Thanks in advance and best regards,

    1. to help with the confusion about the DUMP function: index realizes that the DUMP function can be performed in the remote database. Oracle tries to push as many functions as possible and semantically correct on the remote site. Therefore, it sends the statement of simple table on the remote site after stripping the DB link. In this case, the DUMP function sees the character set of the remote database and creates the resulting string of information. This string of AL32UTF8 to EE8MSWIN1250, as described in the note, but as all the characters in the string of information are pure ASCII, some codes are actually changed.

    Things get more interesting if you start to combine the tables of local and remote databases. For example, the following query is will normally return the character of local database defined for the two columns:

    select dump(xx,1016),dump(yy,1016) from (select x.dummy xx, y.dummy yy from dual x, dual@dblink y);
    

    This is because the first dual@dblink is transported to the local site and the join is performed here with application of DUMP.

    The following query returns the set for two columns of characters in remote database:

    select dump(xx,1016),dump(yy,1016) from (select x.dummy xx, y.dummy yy from dual@dblink x, dual@dblink y);
    

    This is because all the tables are remote and the entire query is sent to the remote database and y.

    The following query returns the remote character set thus:

    select dump(xx,1016),dump(yy,1016) from (select /*+driving_site(y)*/ x.dummy xx, y.dummy yy from dual x, dual@dblink y);
    

    Here, the DRIVING_SITE hint asks the database to perform the join in the database of the table, for example dual@dblink.

    2. to answer your question:

    Your understanding of the way of conversion is generally correct, but conclusions are not quite correct. In the scenario [client EE8ISO8859P2, EE8MSWIN1250 local database, remote database AL32UTF8], Eastern and Central European characters will work correctly, but the other characters to the remote database will not be (for example, French, Greek, Chinese). It is, I think, quite clear and is usually not a major problem, as usually only compatible languages EE8 are interesting for an EE8ISO8859P2 customer. However, in the scenario [customer AL32UTF8, EE8MSWIN1250 local database, remote database AL32UTF8], the problem becomes more visible. Having a taking customer support Unicode, you can recover some data French or Greeks of the remote database but you will fail as all of these characters will be "killed" by the conversion of distance at the local level (link DB conversion).

    EE8ISO8859P2 is also for the same group of languages, such as EE8MSWIN1250, indeed, but it lacks some interesting characters. The most important of them is the symbol of the Euro. Others are "' quotes, long dashes, TM symbol, and a few other less frequently used punctuation. Therefore, always define a database as EE8MSWIN1250, even if you run some clients (Unix) with EE8ISO8859P2. Do not run Windows with EE8ISO8859P2 clients, except for purposes of loading/generation of special file.
