What's the best way to subscribe real-time on parameter value changes on DataMiner North-bound?
There is an (yet to be documented) websocket connection possible.
I did get some additional help from Wim per e-mail. But it requires to make some calls to the Internal.asmx api. So i'm not sure if i can share it here as well.

I’m not sure, i’m currently using it to observe alarms they seem to be real-time. But i saw they have some Observer Tables as well.

did an quicktest with the ObserveParameterTable:
Realtime: yes
Large amounts of updates unsure. Keep in mind that i tested with an Json response where the initial response was over (table of 1302 rows) 122844 lines of json
Does this support subscribing to real-time value updates of parameters?
How does it handle large amounts of updates?
