>Description:
nfsstat on FreeBSD lacks the following useful options/features,
taken directly from the Solaris 7 man page:
-m Display statistics for each NFS mounted file sys-
tem. This includes the server name and address,
mount flags, current read and write sizes, the
retransmission count, and the timers used for
dynamic retransmission. The srtt value contains
the smoothed round trip time, the dev value con-
tains the estimated deviation, and the cur value
is the current backed-off retransmission value.
Here are what the stats look like (this is sweet):
/m/t from ro:/
Flags: vers=2,proto=udp,sec=sys,hard,intr,dynamic,rsize=1024,wsize=1024,retrans=5
Lookups: srtt=1 (2ms), dev=1 (5ms), cur=0 (0ms)
Reads: srtt=7 (17ms), dev=3 (15ms), cur=2 (40ms)
/m/k from kahuna:/
Flags: vers=3,proto=tcp,sec=sys,hard,intr,link,symlink,acl,rsize=32768,wsize=32768,retrans=5
And:
-z Zero (reinitialize) statistics. This option is for
use by the super user only, and can be combined
with any of the above options to zero particular
sets of statistics after printing them.
The -z option helps diagnose NSF performance problems.
The only way to zero the nfs stats right now is to reboot.
It gets even better:
-r Display RPC information.
This is a minor improvement; it reduces the total info
to RPC data only.
>How-To-Repeat:
1. Compare the FreeBSD and Solaris man pages for nfsstat.
2. Try to debug an NFS performance problem with FreeBSD,
then use Solaris.
>Fix:
Add options/feature(s) to the code.
