Hello,
Do you mean a Client monitoring Alarms created by a Server when you say “get all alarms in ua server”? That has already been answered in this thread: https://forum.prosysopc.com/fo…..ng-alarms/
Or do you mean something else?

Hello,
You mentioned that you are “creating a REST API”, does it mean that you are developing a UA server with REST API?

Hello,
No, I am developing a REST API that through an ua client, retrieves the alarms generated by the ua server.

Hello,
after you have subscribed to Server Object for Events, you can call ConditionRefresh manually:
client.call(Identifiers.ConditionType, Identifiers.ConditionType_ConditionRefresh, new Variant[] {new Variant(sub.getSubscriptionId())});
“client” here is your UaClient object and “sub” is the Subscription object ConditionRefresh is called for. This will return all active alarms and conditions.

Hello,
Sorry that “return” might be a incorrect word here. ConditionRefresh itself doesn’t return anything. Your server will resend notifications for all active Conditions. Please check OPC UA Specification Part 9 for more information.
