OPCUA : Monitoring mode


I am using telegraf opca plugin for collecting data by polling it every 1 second, It is working as expected not issues in this.

Now, I want to update few parameters to store only on change, hence I want to setup monitoring mode (change trigger) on opcua side so that I will only receive data at output side when there is change in parameter value.

I went through telegraf opcua GitHub page for documentation, but didn’t found anything related monitoring parameters.

Any idea how can I achieve this?
Thanks in advance.!
