Re: [milo-dev] 回复: How many request does the monitor support when subscription

The answer is server specific. You should be able to create thousands at a time. The server will respond with Bad_TooManyOperations if you're trying to request too many at once. In this case you should create the items with multiple requests. 

Some servers also expose a operation limit nodes in the address space that tell you how many. Try reading the value of this NodeId: Identifiers.ServerType_ServerCapabilities_OperationLimits_MaxMonitoredItemsPerCall

主 题:[milo-dev] How many request does the monitor support when subscription

Hi, 

When call function createMonitoredItems to create monitor, the second parameter is request list,  how many request does the monitor support?
Tens of thousands of nodes need to be subscribed in our warehouse,I don't know the support status and performance, Could you provide some theory and test data?

Thanks!

Best regards,
George Ray
