SYNOPSISmountstats [−h|−−help] [−v|−−version] [−f|−−file infile] [−S|−−since sincefile] [ [−n|−−nfs] | [−r|−−rpc] | [−R|−−raw] | [−x|−−xprt] ] [mountpoint]... mountstats iostat [−h|−−help] [−v|−−version] [−f|−−file infile] [−S|−−since sincefile] [interval] [count] [mountpoint]... mountstats nfsstat [−h|−−help] [−v|−−version] [−f|−−file infile] [−S|−−since sincefile] [−3] [−4] [mountpoint]...
DESCRIPTIONThe 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.
Sub-commandsValid mountstats(8) subcommands are: mountstats 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. iostat Display iostat-like statistics. nfsstat Display nfsstat-like statistics.
OPTIONS
Options valid for all sub-commands−h, −−help show the help message and exit −v, −−version show program's version number and exit −f infile, −−file infile 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. −S sincefile, −−since sincefile 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.
Options specific to the mountstats sub-command−n, −−nfs Display only the NFS statistics −r, −−rpc Display only the RPC statistics −R, −−raw Display only the raw statistics. This is intended for use with the −f|−−file and −S|−−since options. −x, −−xprt Display only the transport statistics
Options specific to the iostat sub-commandinterval 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. count 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.
Options specific to the nfsstat sub-command−3 Show only NFS version 3 statistics. The default is to show both version 3 and version 4 statistics. −4 Show only NFS version 4 statistics. The default is to show both version 3 and version 4 statistics.
