Unwanted interface Alarms and Events in PI2.0

We receive a lot of interface events and alarms from our 3560s access ports. We have not deployed any interface monitoring yet but still hundreds of alarms and events warns us about interfaces going up and down. Anyone who know why Prime is monitoring all interfaces and how to disable that?
Many tanks in advance

Additional lab tests shows that all interfaces of a device indeed is monitored by snmp. When an interface changes from UP to DOWN/DISABLE an event and an alarm is generated. We have not deployed any "Interface health montoring" and still the interfaces are monitored. Not good for access ports.
As a workaround we created a new Interface health monitoring template with the interface availability check disabled and just one other check enabled (interface util) and deployed it on two specific ports on a switch. Did not help. Alarms were still generated when the access ports were disabled.
Any ideas?

Alarm and Event Query Very Slow

Group,
I am using the DSC Alarm and Event Query vi to pull data from the SQL database (not the Citadel). I have a filter set up that specifies the "Alarm Area" and the start and stop dates with maximun results set to 22. These dates are set to only pull the last 24 hrs. This vi will return around 10 to 20 entries out of perhaps 80-90 total events in the last 24 hours in the database. This database is ~2M in size. I have to set the timeout to almost 10 min for this vi to not produce a timeout error. The results returned are correct but it just seems that the time to run this vi is excessive. It is quering a database on the same system that the quering vi is running on. Should I expect better preformance?
Thanks
Todd

Verne,
I have boiled down the code to this attachment. This query took almost 7 min to return 22 results from a database size that is listed as 2.09877E+6. I have also tried the Alarms and Event Query to spreadsheet vi also and it takes the same amount of time. I am wondering if I place the Alarms and Events into the same (Citidel) database that the traces are going if it would be much faster. I seem to get trace data back very fast. If I recall correctly I seperated the alarms from the trace because I was having some sort of problem accessing the alarm data in the combined database...but that was several labVIEW versions ago. Anyone else having this problem?
Thanks
Todd

Prime Infrastructure: Can you export Alarms and Events?

Hello
In Prime 1.4, you had the ability to export the alarms and events you saw being reported, at least according to the PDF manual: http://www.cisco.com/c/en/us/td/docs/wireless/prime_infrastructure/1-4/configuration/guide/pi_14_cg.pdf
I want to export these events and alarms that can be found in the Monitor section of Prime 2.1, but the export option does not seem to be available.
Does anyone know if it is possible to export these via a scheduled report or by looking in a particular place on Prime? I would like to import the information into Splunk to see if we can gain an insight into the information that is being collected.
thanks
Bryn

HI,
Did you ever determine an answer to this question? I really need to export data after a certain date... (I would also like to publish a calendar, after a certain date-- as no one needs to see the "old" events).

Alarming and Event Data Storage Locations

I'm having a problem where the Alarms and Events files are filling up the system disk and causing Lookout to crash. Is there any way I can set things up so that those files are stored on another disk? I already have the Historical files being archived on a separate disk, but the alarms and events seem to have stayed on the System disk. The system disk doesn't have that much free space all the time, which is why I put the historical files somewhere else.
Also, I have the Historical Data system set to only archive data for 90 days (it was changed a while back from storing perpetually), but I still have files in the database going back years. Is there a way to purge the old data out?
David Dudley

David,
It's important to note the alarms and events are actually in a separate database from Citadel.
This KnowledgeBase article discusses removing/archiving alarms from the database:
http://digital.ni.com/public.nsf/websearch/B23BDD585BAEB25086256C00005C2851?OpenDocument
Moving the alarms database is a bit more tricky. It uses the MSDE 2000 SQL engine, which defaults to using a database on the drive it gets installed to. I think short of installing Lookout to another drive, there's no "easy" way to move it over.

[Bug?] DSC - Clusters Different between 'Read Alarm.vi' and 'Alarm and Event Query.vi" but Contain 'Same' Data

Howdy!
Why are the clusters different coming out of the Read Alarm.vi and the Alarm and Event Query.vi when they have the exact same data?
The only difference is the order of two last elements.
I am leaning towards bug on this one, unless these clusters need to be distinct for some reason?

Thanks for posting Ravens Fan
I re-jiggered my API to reverse my datatypes then applied changes to my application code.
It wasn't that painful to update.
My current understanding is that this bug affects one VI, so I decided it was easier to wrap that VI with the bugfix.
Attached is my implementation if anyone wants it too.

Alarm and event related problem

hi dear all
again my problem needs u
On upgrading my project from labview 6.1 to labview 7.1 version i have problem in generating alarm related .ALR file which i further use in my software. for this i m using "legacy_hist_alarms_&_event_Query_to_spreadsheet_file.vi" this vi but in labview 7.1 i replaces it with
"Alarms and event query to spreadsheet file.vi" but its number of display format and filter elements are changed i also changed these.
but how i order the elements so i correctly connect with vi . i tried acc. to error list but it gives error every time so pls give the example or any suggestion regarding the order of elements .
i m thankful to u all in advance
regards,
Dhanwanti

Dhanwanti,
What error are you receiving when you try to connect to the VI? What do you mean by "order the elements"? Are you talking about the inputs to the VI? If so, the easiest way to connect to these are to right click on the terminal and select "Create -> Control", which will make a cluster that connects to the VI.
Let me know if this helps.

Alarm and event logging has stopped

Alarm & Event Logging with Citadel 5 and Lookout 6.02.
I have a continuously running application that stopped logging alarms and events approx. 6 weeks ago. (March 07, 2010) The problem went unnoticed until a recent event/alarm sequence needed to be investigated. Data traces are not a problem. They are visible using MAX as well as with Lookout hypertrends. However, MAX shows nothing for alarms or events past that date. (No problem earlier, going back to 2002)
The Alarm panel in Lookout will show the alarms and events as they occur so I know they're being detected.
I understand that the data traces are logged to Citadel, whereas alarms and events are passed to the MSSQL server. (In my case the free version that comes with XP - SQL Server Express I believe.)
This version has a database size limit of 4 GB. What exactly does that mean?
An *.mdf file >4GB cannot be created?
An *.mdf file >4GB cannot be read?
The total size of all *.mdf files cannot exceed 4GB?
Curiously the file in use is 1.99GB. When archived, it is only about 750 MB, yet the total number of alarms and events are the same in each. There are other *.mdf files that exist on the system but aren't in use.
NI document 4GPBLT21 states "Once that limit is reached, the alarm and event data is logged to the high performance Citadel database". Then what? Is that data viewable with MAX?
MAX doesn't appear to have any tools to selectively delete old alarms or events.
How can I determine what has happened and what do I need to do to restart the logging?
Any and all help most welcome.
Bob L

Lookout 6.0.2 uses SQL Server Desktop Engine which has the limit of 2G, so your alarm/event database has already reached the limit.
After the SQL database is full, the alarm/event will be logged to Citadel database. But this maybe reduces the performance of Citadel, that's why we log alarm/event to SQL Server first. But I'm not sure why the alarm logging is stoppted.
To delete the alarms from SQL Server is not straightforward. One way is to archive it. Follow the steps below.
1. In MAX, create a new database in different folder.
2. Create a Trace View and add the whole old database to the trace view.
3. Right click on the Trace View and select Archive. Archive all to the new database. You don't need to specify the time range.
4. After the achiving, the new database will have all the trace data and no alarm data in it. You can detach the old database.
In Lookout, select File->Modify Process to change the database to the new database. Or you can change the system default database from Option->System. And then the lookout process will use the new database which has no alarm in it.
You can keep the old database files. All the data and alarm/events won't be lost. When you need them, you can attach the database.

"alarm and event display" crashes my application

Dear All,
I use the "alarm and event disply.vi" in my DSC application. It works fine: I can acknowledge alarms, events etc. BUT...
When I double click the alarm item (or press Alt-Enter) and watch the alarm properties in the Alarm Properties dialog, I can usually watch the properties for some time, selecting the next or previous alarm item, but most often than not, my application just crashes. I don't get any LabVIEW error dialogs. Only Windows is telling me that the application stopped working and it just closes giving me no explanation. Sometimes I don't even see the Windows message.
I've tried this on two different computers... same boat!
I'm using:
- LV2011
- Windows 7
In my application I create the shared variables programmatically, set alarm thresholds programmatically etc.
Anybody had the same problem?
regards
Witold Nocon

Well…I think I have isolated the problem, and I have recreated it in the Boiler example. Here’s what’s happening:
If you watch the properties of the alarm in the Alarm and Event Display, and if this alarm “disappears” at this time, the application will crash. This will happen for example when this variable is set to AUTO ACK.
You can try setting the R02 pump to zero. This will cause the L01 level to increase reporting an alarm. Now if you set the flows so that the level start decreasing (I set the outflow to max, and the inflow tozero), and immediately click the HI HI alarm and watch it’s properties, the application will crash at the time when this alarm is cleared due to the decreasing level (AUTO ACK).
It also seems a “little non-deterministic” but this may be my own impression.
Anybody had a similar problem or is able to recreate it?

DSC 8.01 Configuring alarm and event display control

Hi all,
How to configure the columns in this control (alarm and event display control) in order to hide columns, changing the langage ?
In the previous DSC version it was different.
Thanks
Best regards,
Julien

Hello Julien,
At my knowledge, such a control is not customisable. I think you should use the "Alarm and query filter" control (in your FP) linked to the filter input of the "Alarm and query" vi (in your diagram). This should enable you to select the alarms to display

Alarm and event notification DSC

I can't understand the functionality of these DSC VIs:
Acknowledge Alarms .vi
Set user Defined Alarms .vi
Request Alarm & Event Notifications .vi
I appreciate any guide.

Hi Maryam,
Acknowledge is where the sequence action that indicates recognition of a new alarm.
Where an alarm is an abnormal process condition. In the LabVIEW Datalogging and Supervisory Control (DSC) Module, an alarm occurs if a shared variable value goes out of its defined alarm limits or if a shared variable has bad status.
This is the URL of the DSC module Glossary:
http://zone.ni.com/reference/en-XX/help/370246D-01/lvdschelp/dsc_glossary/
If you want to know more about the general functionality of alarms and events and what to use specific VIs for.
The fisrst call as I said previously should be the context help, check the example library and the NI developer zone. Another reasource which you can check is the DCS module "VI, Function, & How-To Help".
Click on the "Help" then "VI, Function, & How-To Help", expand the following items in the tree structure "DSC Module"> "DSC Module VIs & Functions" > "Alarm & Events VIs".
For future reference it would be helpful in future if you gave more information in your posts eg what version of LabVIEW you are using - so can post back relevent versioned example code.
And what you are trying to do - why are you interested in the DSC alarm VIs, could make more specific replies given this information.
Sorry if my initial replies are basic but I had no way of knowing the level of information you were looking for and you did not say what you had already tried/ looked up.
Alarms can be used in many applications but as I said their basic functionality is to alert the user to an abnormal process condition eg sub/super limit values or bad status.
I hope the above helps but if you require more information please let me know what it is you specifically want to know.

Custom alarm and event view

Hello
I tried to create custom alarm&event view. I used "read alarm.vi" and "format alarm data.vi" to fill multicolumn listbox where i changed columns names. Why alarms disapear when they are not active anymore? How can i change that? I would like to have all alarms in table, new and old ones. How can I change colors when alarm is active, inactive or ack?
thanks

Hi
I did it, but... There is always but. I've changed columns names, switch position of 1st and 2nd, and 3rd and 4th column, and alarms in different state have different color. But its not working properly. Few seconds table is changed and few seconds in not. Maybe my PC is too slow, or is it something else. Please look at picture in attachment. Is there easier way to do it?
Thanks

LMS 4.2 Alerts and Events

I tend to get alarms/events that I really would rather not see. For instance, I have a voice router that consantly shows BACKUPACTIVATED, which is the intended use of the ports. Also I have another alert/event for CARDS whose Status is NOT PRESENT. I'm not really concerned about these, but I'm sick of clearing them manually all the time. Is there a way to prune or weed these out so I no longer have to see them in the fault/event managers?

If you have nothing selected by default , you will be notifed for every event.
creat a Event set with the Events you are interested in and use that event set ( lets say A) in the Notification Group and this should work.
Read the below document for more understanding of the Alarm and event :

INTERFACE AND EVENTS IN ABAP OO

Can some one explain me the real time need with example for use of interfaces and events in abap objects
(asking interface and events along doesnt mean that i am relating them).
<removed_by_moderator>

Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.
Cheers.

MM Cal. - how to set default new event to a email alarm and two days??

I create events from what ever is close ipad iPod. It would be very helpful if the MM calendar could be set to email alarm and a two day lead. I know there are alternative todo etc.; but This would be much better.

Generate Prime Interface Availability and Utilization Report for unified APs

Hi,
I´m trying to generate interface availability and interface utilization report for unified APs on Prime Infrastructure 2.0, but it doesn´t display any information. I have created device health and interface health templates under desing/Monitor configuration/My templates and deployed under Deploy/Monitoring deployment, but it still don´t show any information,
thaks for your help.

Hi Alejandro,
Did you solve this problem? Or is it a bug?
I face the some issue with you, I just run "Report/Report Launch Pad/Deivce/Interface Utilization"
and then I create a report for interface utilization.
But it display nothing when the report run finished.
I ask some guys in this forum, they said maybe it's a PI2.1 bug.
