I am Using NodeOPCUA To detect Variable change,So i am using this code as ref
https://github.com/node-opcua/node-opcua/blob/master/documentation/creating_a_client_callback.md
Every thing is working fine, only i need to is it possible to monitor multiple Variable value change in one subscription ,if possible please share the ideas, Thanks

I have simple game on Google Play and Apple App Store that I have created in Unity. Now I am thinking about creating a global high score, so if you are in top 10 for example you can enter a made up user name.
The thing is I do not want the users to sign in since I want the game to be easy to access. One user can also enter a new username each time a record is beaten. So you can for example have the first three positions.
In principle, the app should read the high score from database and one should be able to write to it with {userID, new_score}, but no data is connected to any particular user. I am used to work with Firebase, what would be the easiest way to achieve this?
Thanks,
Erik
Well, the fact that you don't have data connected to any particular user do not means that you can't store the highscores. Cause one user can beat himself.
So if your database (I don't know if it's realtime or firestore) knows which are the top scores, when a user (indpendently of his ID) beats the score threshold, you can give him the option to put a name on that highscore, and update your database with this new score.
I will also recommend to bind users with data, his highscore or the name it's using to register the highscore, but you can achieve the same result without it.
You could try having a read and create only set of records, where write requires a valid anonymous auth key. I haven't tried that setup with Anonymous only auth before though.
Otherwise you could also try setting up a cloud function to validate and write the high score records.
I am very new to Anylogic and am trying to send/receive information between agents, but not sure how to accomplish that. Attached please find an image which shows connections between agents. It also shows two-way connections between agents and dependent variables 1.
What parameters/settings does one need to change to develop such a diagram?
So far I have tried embedding a dynamic variable inside the agent and then drawing a connector between the agent and a dependent variable - but doing so replaces the agent icon with a dynamic variable icon.
you cannot connect agents graphically with connectors (except in special cases).
Normally, you use the "Agent Link" objects to establish agent connections and send messages. In short, you do the following:
drag it into agent type 1
Set it up to connect to agent type 2
when it asks to create a corresponding Agent Link object in type 2, agree
Now, you have a way to connect agents using the agent link object.
Do check the AnyLogic help and tutorials on that, there is a lot of info on how to use them.
Here is the situation:
I've got the application that requires different actions for different months. For example if I'll create a task that requires some actions for next 5 months I need some kind of method to keep jumping ti next months to confirm correct behaviour.
Usually I would just connect custom NTP for the server and than change date to whatever I want but this application works on Sharepoint online and as far as I know I can't do that (even if I'll it will affect all users not app under test only).
Another problem is that method should be easy and possible to explain or at least show to business during UAT.
Thanks in advance.
When I append a new subscription in ORION, it automatically evaluates the condition and it invoques the designed end-point for that. I want that the new subscription affects only entities appended later.
Is there any way to avoid it or I have to control this at end-point level?
Related to this, is there any batch option to create several subscriptions at same time for a initial load of the platform?
Orion Version: 1.2.0
Regarding initial notification:
No, it isn't.
We understand that for some uses cases this is not convenient. However, behaving in the opossite way ruins another uses cases which need to know the "inicial state" before starting getting notifications corresponding to actual changes. The best solution to make everybody happy is to make this configurable, so each client can chose what it prefers. This feature is currently in our roadmap (see this issue in github.com).
While this gets implemented in Orion, in your case maybe a possible workaround is just ignore the first received nofitication belonging to a subscription (you can identify the subscription to which one notification belongs by the subscriptionId field in the notification payload). All the following notifications beloning to that subscription will correspond to actual changes.
Regarding batch option to create several subscriptions
No, there isn't any operation like that.
EDIT: the posibility of avoiding initial notification has been finally implemented at Orion. Details are at this section of the documentation. It is now in the master branch (so if you use fiware/orion:latest docker you will get it) and will be include in next Orion version (2.2.0).
I am using Gatling and am running into an issue implementing an integration test. The test I am running has two parts (scenarios):
The first part is a simple GET request to verify expected server responses. In this step, it returns a form's configuration ID as well as other properties of the form.
In the next step, I am hitting PUT route which updates various properties of this form's configuration for testing of this route and other functionality through the back ends of an application.
The issue with these steps is that after running the second step, if there are any forms saved under that configuration, it will clone a copy for security purposes and changes the ID. Long story short, the same ID does not persist from test to test.
My question is: Is there a way within Gatling to run SQL Queries to get values and store them and then pass them? OR is there a way to store a variable from the GET method and pass it in in the second scenario's PUT method. I know there is Gatling's .saveAs() method, but I believe the scope of this function is only scenario.
Please notify me for further clarification and details; thanks in advance.
The Google group link only shows you how to share (&cache) data between different user-sessions.
If you are looking for sharing data between "scenarios" rather than "user sessions", you should check out Peter's answer: https://stackoverflow.com/a/43061278/1395126
It's the only information I can find on the internet today that really shows you how to share data between scenarios in Gatling.
IMHO, it's super important to look out for the line of "// Set it here" comment. This is THE secret about sharing data among scenarios. Without setting session attribute first or accessing the "CreateId" directly in another scenario could not work.
This answer: https://groups.google.com/forum/#!topic/gatling/bfpKd_9d6gk can probably be used to handle your use case.
