Hello all, I am aiming at integrating the NETLINK patch, submitted last year, to the latest version of net-snmp, in the coming two months. The purpose of this patch is to bring instant (relatively...) notifications when an interface is brought down/up.
The patch works with a prior version of net-snmp but is currently broken in the latest. We get response times within a second of the event. This patch was made by a collegue (Michael Leslie), so I have direct access to info about its implementation. I see that the topic of a NETLINK-based mechanism (and specifically of that patch) was brought up recently in an IRC session (dts12, hardaker - simple clusty.com search ...). I'm glad that there's interest in it since I do see the benefit of having an immediate response to such interface status changes as opposed to periodic polling. From our perspective, users do want to know about a router's interfaces status changes, quickly. The quickest the better. Now, I do not have an URL about follow-up comments to that patch at the moment, but I recall having read that it was somewhat mentioned that the place the mechanism was located was not ideal, eg. DISMAN. Before doing anything I would like to know the feedback of the net-snmp coders community so that the functionality is optimally better integrated to net-snmp and can survive many revisions :-) So please, do not hesitate to comment. I will appreciate any feedback. Perhaps it'd be possible to integrate immediate responses of any kind from the NETLINK mechanism in a more flexible framework that could cater to various needs. I surely would like to see something along that way, if possible at all. If there's already work being done regarding this, perhaps we can work together.
