mountstats - Displays various NFS client per-mount statistics
mountstats [-h|--help] [-v|--version] [-f|--file infile] [-S|--since sincefile] [ [-n|--nfs] | [-r|--rpc] | [-R|--raw] ] [mountpoint]...
mountstats iostat [-h|--help] [-v|--version] [-f|--file infile] [-S|--since sincefile] [interval] [count] [mountpoint]...
mounstats nfsstat [-h|--help] [-v|--version] [-f|--file infile] [-S|--since sincefile] [-3] [-4] [mountpoint]...
The mountstats command displays various NFS client statisitics for each given mountpoint.
If no mountpoint is given, statistics will be displayed for all NFS mountpoints on the client.
Valid mountstats(8) subcommands are:
Display a combination of per-op RPC statistics, NFS event counts, and NFS byte counts. This is the default sub-command that will be executed if no sub-command is given.
Display iostat-like statistics.
Display nfsstat-like statistics.
show the help message and exit
show program's version number and exit
Read stats from infile instead of /proc/self/mountstats. infile must be in the same format as /proc/self/mountstats. This may be used with the -S|--since options to display the delta between two different points in time. This may not be used with the interval or count options of the iostat sub-command.
Show difference between current stats and those in sincefile. sincefile must be in the same format as /proc/self/mountstats. This may be used with the -f|--file options to display the delta between two different points in time. This may not be used with the interval or count options of the iostat sub-command.
-n, --nfs Display only the NFS statistics
Display only the RPC statistics
Display only the raw statistics. This is intended for use with the -f|--file and -S|--since options.
Specifies the amount of time in seconds between each report. The first report contains statistics for the time since each file system was mounted. Each subsequent report contains statistics collected during the interval since the previous report. This may not be used with the -f|--file or -S|--since options.
Determines the number of reports generated at interval seconds apart. If the interval parameter is specified without the count parameter, the command generates reports continuously. This may not be used with the -f|--file or -S|--since options.
Show only NFS version 3 statistics. The default is to show both version 3 and version 4 statistics.
Show only NFS version 4 statistics. The default is to show both version 3 and version 4 statistics.
