  • 1.  TMF 640 Monitor Listener query

    Posted 22 days ago

    Hi All,

    I want to know about  monitor event Listener : monitorCreateEvent, monitorAttributeValueChangeEvent, monitorStateChangeEvent & monitorDeleteEvent.

    On which use case I will use these event in TMF 640 (serviceActivationandConfiguration).

    Can you provide scenario example it would be a great help.

    Hi Shivam

    The Monitor pattern was introduced a while back, specifically for Service and Resource Activations, recognizing that the operation of activating or configuring in the network is likely to take time (seconds, minutes?). So as not to block a consumer thread, the API implementation allows definition of a monitor, which will notify the consumer when the activation request (POST/PATCH) is complete.

    It could be argued that this could be addressed in other ways, e.g. by events, or (in the future) by Async API.
