Subject: Re: [wsdm] Requirements for Management Using Web Services
Pankaj, This is an excellent start! Here are some of my comments, alongwith the appropriate context from your write-up - Management Interface Requirements Section Requirements on Web Services (generic): > 3. Web Services Identification Actually, this is more general - "Managed Resource Identification", since management products compliant with WSDM will manage resources other than web services as well. This is the first issue we need to agree on as part of a building block for the rest of the spec, in my opinion. > 9. Support for events Aren't existing message mechanisms sufficient for what we need? Maybe you can elaborate on this during the conf call tomorrow. > 12. Discovery mechanisms Scalability Requirements: > 1. It should be possible to off-load certain kinds of processing/ > filtering at Agent to reduce network traffic. I think we should be more specific here, since this aspect deals a lot with operational/implementation issues. Possible kinds of filtering or work to be offloaded to the Agent: a) computation of derived statistics b) event co-relation (sequence and time-based) c) local root-cause analysis (??!!), d) ... > 3. A Manager should be able to support a large number of > Managed Resources. This is also subjective and "close" to operational/implementation aspects. What is the scale here - ten's, hundred's, thousand's? I think the ability to multiplex across ten's of "children" at the Manager and Agent level might be more appropriate. Also, we are not saying anything regarding the levels of hierarchy a product could support amongst the Manager -> Agent -> Managed Resource layers. Other views are welcome if I am off-base here. Also, it might be useful to add a section on "Usability" as well. One aspect I can think of right away for this is - - It should be possible to configure an operation on more than one Managed Resource, rather than having to go through a configuration step for each Resource.
