  • 1.  TMF 640: Servic create event vs Monitor create event

    Posted Dec 09, 2022 10:17
    Hi There,

    Could you please guide me to understand the difference between TMF 640 service create event and monitor create event. Under what scenario service create event to be used and under what scenario monitor create event to be used ?

    Hi Suresh
    The Monitor pattern is a special case of an API that is likely to have asynchronous behavior - currently it is used only in Service and Resource activation (TMF640 and TMF702), since direct communication with network elements is expected to take longer than 10's of milliseconds, and perhaps you wouldn't want a thread blocked waiting for a synchronous answer. So you can use a Monitor to help understand when the POST (or PATCH) operation is complete.
    The Service Create (or attribute change) event is an alternative mechanism for discovering when the operation is complete, using the event hub pattern that is common across all APIs.
    Please note that the Open API team has started to look at adopting AsynchAPI, which could possibly render the Monitor pattern obsolete. See the early adoption page https://projects.tmforum.org/wiki/pages/viewpage.action?pageId=128855518 for an initial example TMF925 Trouble Ticket asynchronous.
    Hope it helps

    Hi Jonathan,

    Can it be said that if notification is triggered from Network element or other south bound system than it is monitor create event and when the status is requested from Service order management it is Service create event?

    Thanks
