Re: [netmod] I-D Action: draft-ietf-netmod-syslog-model-08.txt
Tom, In the latest draft I have removed an action, some features and shortened more names. I think that we are close to the minimum functionality that should be specified.

Sorry, if there was a miscommunication. I thought the rational that networks devices are rarely configured as syslog servers made sense. I will let the WG decide if they want to keep syslog server configuration. We were discussing ssh server and client configuration and the desire to include that as part of the work (being done by Kent and others in NETCONF WG).

Hi Clyde, I was a bit surprised to see the receiver/server side config in here (log-input-transports). That seems to be a somewhat significant change in scope. I thought the focus of this was more on the generation & distribution. Do many implementations have functionality that maps to this log-input-transports ? In any case the pyang tree has log-input-transports but it doesn't seem to be down in the actual model itself. But I'd be inclined to just remove this from the model. Maybe Mahesh has some thoughts here (I didn't see a posting about this in the mailing list). I agree there are multiple implementations of console, buffer and session logs. But maybe 'terminal' should be removed or an if-feature ? I'm not sure that one is so widespread (not in JUNOS, not in SR OS). Buffer-limit-messages and having multiple log buffers are both supported by Nokia SR OS. I would think that both of those would have support in other logging implementations as well. I'm not sure if Tom P. was really concluding that there are no implementations of these in his email. Do we have multiple examples of implementations that limit log buffers using bytes ? Buffer-limit-messages would be easy to do as an augmentation but making the log-buffer a list is probably something we should just do from the start. That is also consistent with all the other types of actions (except console of course). The use case for multiple log buffers is that you might sort/filter different types of log events into different circular buffers (i.e. have one for really critical log events, etc) for viewing on the node.
