Generate event

Hi All,
I am using Labview7.0 and need to generate automatic event. It means without any button press or mouse move activity on front panel, i want to generate event after every particular time interval.
How i can fullfill my requirement??
Regards,
Ratna
Solved!

Hi Ratna,
Dynamic event registration gives you increased flexibility in controlling how and where events are handled in your application. You can try the attachment. It should open in LV 7.0.
Thanks,

How to manually generate events in SMC 3.5 ?

Dear,
We are using the SDK of SMC 3.5 to build an application. To test the application, how can we generate events manually ? I'd like to have a script on Solaris that, when run, generates an event in the SMC database. Does anyone have such a script ?
Best regards,
Marc.

Can I use AWT elements in a JSP, and so could I generate events with them?

This is because I�m doing a simple JSP that showing a button, my JSP is:
<html>
<%@ page import="java.awt.*" %>
<%! Button b = new Button("Hola!!!"); %>
<% add(b); %>
</html>
But when I tried to see the button in the browser, my JSP generates the following:
Compilation of '/RAID5/weblogic/myserver/classfiles/jsp_servlet/_gep/_alterno/_23_mayo/__mr4.java' failed:
/RAID5/weblogic/myserver/classfiles/jsp_servlet/_gep/_alterno/_23_mayo/__mr4.java:79: cannot resolve symbol
probably occurred due to an error in /gep/alterno/23_mayo/mr4.jsp line 7:
<% add(b); %>
Could somebody help me please?.....

There are 2 ways to run a web page dynamically:
1) Reload the page via use of javascript or some other scripting language.
2) Use an applet to regularly check a URL for the data
Remember, as Paul pointed out, JSP's only generate HTML output. AWT components need to run inside a JVM not a just the browser.
I could recommend an applet but you may have problems with IE6 not supporting java. Otherwise there shouldn't be too much of a prob.
If you prefer to use an AWT/Swing setup (for example an application) rather than a JSP setup, Webstart is good for delivering online applications which operate standalone or remotely.
When you consider that the Java-Plugin and the Webstart puligin are about the same size it's just a matter of weighing up who your target clients are and whats easiest.

Generating events such as "push buttons" in ABAP

Hi,
Is it possible to make code in ABAP that given a screen number can generate events for that screen.
For example create a Z program that given the input parameters screen name and transaction, do something like:
screen 101.pushChangeButton.?
regards
Baran

yes see this code.

Differences between Robot class generated events and real input events

Hello everyone!
I'm having a problem with the translation of the description of the awt.Robot class.
- "This class is used to generate native system input events" -
Does this mean there is no difference between real input events and generated events from the Robot class? Difference in reference to that the generated events can't be recognized as generated events by the os or programs.
Thanks in advance.
Chris B.

The Robot class will use an interface provided by the operating system to inject events. Those are very close to 'real' input events, but not quite there. There are, for instance, several games out there which have a protection mechanism against Robot's events to prevent scripting/botting. However, any application that is not paying special attention to the event's source will assume that the input events generated by Robot are actually coming from the user, so you can 'control' any application with the exception of the beforementioned games.

Event monitor cannot find PowerShell generated events

I have a basic event monitor that only looks for an event ID and source. The event I am monitoring is generated via Powershell from a remote system rather than being locally created. I'm not sure if that matters, but it sure seems like it.
If I change the event expression in the monitor to look for other events it will generate alerts, it just cant see my PS events. I've tried changing the ID number, the source, using different params, etc... I'm convinced that this is due to the event creation
process and PS must be creating the event in a different manner than SCOM is looking for. Maybe its a bug where SCOM just ignores events created by proxy.
I found this: http://www.systemcentercentral.com/monitoring-events-written-from-a-remote-server-with-scom/
But that is for Rules. I still tried adding <AllowProxying>false</AllowProxying> to the XML of the MP...SCOM didn't like
it.
Has anyone ran into this before?
We are using SCOM 2012R2 fully updated.
- Slow is smooth and smooth is fast.

I guess I should have been more specific. I am using PowerShell to create an event, it isnt an actual PowerShell event.
write-eventlog -computername Server -logname Application -source Orchestrator -eventID 1 -message "This is an example of the events created with PS that SCOM cannot detect."
Maybe I should explain what I'm doing. I have an Orchestrator runbook that does stuff with things. If one of the runbook activities fails, it will send an event to the machine it was trying to run the activity on. SCOM is monitoring for that PowerShell generated
event stating that the runbook failed.
- Slow is smooth and smooth is fast.
I think you haven't native source "Orchestrator" in PoSh log.
Vladimir Zelenov | http://systemcenter4all.wordpress.com
I run a New-EventLog command first to create the Orchestrator source. Otherwise the Write-EventLog command would fail if the source wasn't there. I can see the event there in the logs.

Disabled button generates events

Hello,
I have a radio button that I want to disable while a background process is running.
After the process finishes, I enable the button again.
However, if the user clicks on the disabled button during the background process, an ActionEvent still gets generated.
Then when the button is re-enabled, it responds to the event that was generated while it was disabled. I want to prevent my button from responding to events generated while it was disabled.
I do not want to use the getGlassPane.setVisible(true) technique because I still want my cancel button to be able to generate events during the background process.
I am using JDK 1.3.1 and my button is in a panel contained in a JFrame application.
Suggestions?
Thank you,

Why shared variable generates events when I write constant value?

Hello all,
I'm using LV 8.5 with DSC packet.
I modified "DSC Events Demo".vi and made a test. I noticed that only variable which work okay is double typed. Why this code generate events all the time when I write constant values to shared variables? Double is okay, but string and boolean types not work okay. Is there any other people how have noticed same symption?

You may get an initial event on startup which is normal. Also make sure that you have not enabled timestamp change events.

Generate Events based on Cache size

Hi,
I have a use case where I need to generate events when the size of the cache has reached a specific value. The cache will be highly transactions (lot of inserts and deletes totaling to 6 million transactions per day). Also, I cannot limit the size of the cache as I don't want any data to be lost (trying to insert when cache size has reached its limit).
One of the ways I could do this is to use a MapListener to generate an event on every insert to the Cache, and then check for size each time to decide if the further processing needs to be done. With the nature of the traffic in the cache, the items in the cache are to be processed when the size threshold is reached and then deleted. But, I'm not sure how much of an overhead these events and listeners will have (with 6 million items going through the cache each day)
Is there any other more efficient way to do this? I have looked at Continuous Query cache which uses a filter based on a cache. But, I'm not able to figure out a way to get the size of the cache using a filter.
Any pointers are helpful
Thanks in advance

Hi Vikas,
Typically a size type calculation is the cumulative result of all storage enabled nodes, i.e. a Count aggregation. In your use case you want to be made aware of changes to an aggregation but as an aggregation is point in time of request opposed to continually being updated it does not fit your use case. One option is to create a MapEventTransformer that you register with the cache which increments a counters cache (on a separate service) using an EntryProcessor, i.e.
MapEventTransformer...

                break;

How I Generate Event from ADF to talk BPEL

Hi ,
I want to generate Event in ADF on click of button.
That Event suppose to send message to BPEL process.
Can anyone suggest me on this?
Thanks,
Ramit

You would need to use Mediator component in the SOA composite to listen to this event generated from the ADF layer.
The Mediator can route to the BPEL component where you could do the required processing.
ADF Developer's guide has all the required information with respect to this:

Disabled buttons still generate events

It seems that disabled buttons still generate events in business one. If a button is disabled (even a standard one) click events can still be seen in the SBO event logger. I would have expected a disabled button to be completely disabled and no events to be generated whereas as it is I have to check in the event handler to see if the button is enabled or not.
Is my understanding of this correct?
Has anyone else had issues like this?
Gordon Wood

Hi Gordon,
That sounds like an issue with the SBO Event Logger because no event is actually triggered in the addon when the button is disabled.
Kind Regards,
Owen

IDM Generate-Event in Sentinel

I have an IDM environment setup and I configured the Audit PA to send
events to the Sentinel IDM Collector. Sentinel is setup with the IDM
collector via audit to receive the messages. The setup works fine for
all built-in events.
What I am now trying to do is get custom events created with the
Generate-event token in IDM in Sentinel. They show up as an undefined
event and reference the LSC file. I have located the LSC files, but am
not able to modify those files directly. I have tried modifying them in
the cache, in the zip file after importing, and in the zip file before
posting. I tried modifying them in the zip file, then updating the xml
file with the hash values, but still am not having any luck with this.
The next thing I stumbled upon was the 'Custom Execution Mode'. I have
added the custom.js file and a LSC file which is referenced, but am not
sure of exactly what to add in the custom.js file to make the events get
properly recognized by Sentinel. Currently, my custom.js file has the
following for the customInit section:
Collector.prototype.customInit = function() {
// load additional maps, parameters, etc
var file = new File(instance.CONFIG.collDir + "dirxml_GCA.lsc");
this.MAPS.LSCMap.extend(this.CONFIG.collDir + "dirxml_GCA.lsc",
"#EventID");
return true;
I have uploaded the file dirxml_GCA.lsc and verified that it exists in
the plugins_repository for the aux_Identity-Manager... zip file.

Hi robertivey,
This is a great question; as you've seen we've included some general
methods to customize and extend existing Collectors, but to do so you
also need to know a little bit about how the particular Collector you
are extending works. We have plans to add a bit of specific
documentation to the IDM Collector since it's so common to generate
custom IDM events.
What you need to know is that normal nAudit events contain a number of
pre-defined fields such as Date, EventID, Originator, Target, Text1,
Text2, and so forth. These pre-defined buckets define a datatype and a
little teeny bit of semantics to the values contained within them, but
then on top of that the protocol uses the LSC file to add an additional
layer of semantics on top of the basic elements by adding an additional
descriptor to each field in the event per event ID. So for example
you'll see "Text2 Title" as something like "Client IP" which tells you
that the value in Text2 for event ID 00031550 is the client IP of the
system that connected to and logged in to the UserApp (note that LSC
files use an 8-digit hex value for the event IDs; I believe IDM's policy
code uses decimal so you'll have to convert).
In our IDM Collector, what we've done is written a little parser that
knows what to do for any given value in any given nAudit event field.
For this example, we've written a parser that knows to take the value in
Text2 and put it in Sentinel's "InitiatorIP" field, adjusting for
endianess and the like if necessary. If you look through the LSC file
and through 'dirxml.js', you'll see that for every combination of nAudit
field and semantic LSC definition, there's a defined parser. We use the
nAudit field codes defined at the top of the LSC, so you'll see a
function: "String.prototype["T-Client IP"]", as an example.
Now, to extend this structure is quite simple - you need to define the
equivalent of an LSC file for your custom events. To do this, copy some
lines from the existing LSC into a new file and edit them to match your
events:
1) Change the event ID to match your events. Always prefix with '0003'
- the last four digits are the hex version of your event code, so '1000'
becomes '03e8'.
2) Give your event a name
3) Assign semantic labels to your custom event fields; you should have
paid attention to the first layer of semantic meaning in Originator,
Target, etc, but fill in more detail as applicable.
Note that if you can, re-use the same semantic labels that you see
applied to other, similar IDM events.
OK, once that's done, you need to add your new LSC file to the
Collector using the "Add auxiliary file" process detailed on the
Customization page.
Next, you need to load your new LSC file and use it to extend the
existing one. Simple: from the SDK, grab a copy of custom.js and add
lines like you have above (you don't need to create a new File object
though, the single 'extend' line is sufficient).
Finally, edit your Collector and set its Execution Mode to 'custom',
then restart.
Your events should now be parsed!
The only caveat is that if you don't re-use semantic labels from other
IDM events, you'll need to define your own parser for your own
field/label combination, which you can do in custom.js just by copying
one of the parsers in dirxml.js and modifying the function name to
match.

Collector Rule stays with the same Description after "fast" generated Events - (Custom MP)

Hi , I have a problem to customize one management pack
I use this MP for a reference
http://windowsmasher.wordpress.com/2011/02/07/monitoring-esxi-syslogs-with-opsmgr-2007-r2/
The problem is when I generate event (they are syslog events) the description Data is all the same for some time :)
For example if I generate 10 events fast , the description is all the same , but the data inside is different. MP should take XML element with Powershell script and it's working fine for a "slow" published events.
I don't know why only the description data is the same . I tried to modify the script to NULL the $bag variable and $xmlMessage but without any luck.
Any help will be appreciated
I'm trying to build SYSLOG parser to visualize my data and eventually to do some reports.

Still having a problem? Can you explain a little more what the issue is? Are you saying the event collection provider does not work correctly when there is a burst of events matching your criteria?

Generate event when stack changed

I have a task develop a class Stack that generate event when you add new element ? Develop a class Stack is not a problem, what means event that apears when a new element is added ?[

That about awt / swing ..or I can to apply listeners

It's probably the intention to implement the observer pattern into your code.
Here's a small demo of how this can be done:import java.util.List;
