Garrett Wollman asked me via email how a server admin could tell what usage NFS over TLS was happening. I admitted that there was nothing. I have come up with a patch that generates the following: kern.rpctls.snd_tls_msgbytes: 21508 kern.rpctls.snd_msgbytes: 20828 kern.rpctls.snd_tls_msgcnt: 57 kern.rpctls.snd_msgcnt: 58 kern.rpctls.rcv_tls_msgbytes: 12336 kern.rpctls.rcv_msgbytes: 12072 kern.rpctls.rcv_tls_msgcnt: 57 kern.rpctls.rcv_msgcnt: 58 Basically counts of number of RPC messages and total number of bytes those messages result in. (Both with/without TLS.) Does this seem reasonable or are there better statistics that could be generated? Obviously any other suggestion might or might not be practical to implement. Thanks, rick
