This may be way off on a tangent but some users may also benefit from the CM exposing these as to mmapable so that one can do RDMA reads to gather them. This is useful in monitoring a large clusters of IB nodes as efficiently as possible. This type of scenario has been discussed and researched (see the OSU paper by Panda et. al.).I'd like to start adding some statistical information to the IB CM to help identify scalability or connectivity issues. Some example statistics that I would like to expose now are number of retried MADs, unmatched requests, total number of connections, etc. Longer term, additional statistics and information on each connection could be added.I'm looking for ideas on the best way to expose this sort of data. Any thoughts? - Sean
