NAME

       fnotifystat - a tool to show file system activity

SYNOPSIS

       fnotifystat [options] [delay [count]]

DESCRIPTION

       fnotifystat is a program that dumps the file system activity in a given period of time.

       Statistics  are  output every 'delay' seconds. One can use the 'm' (minutes), 'h' (hours),
       'd' (days), 'w' (weeks) or 'y' (years) suffix to specify large delay intervals. By default
       the delay is 1 second.

       Statistics  are  ouput  'count'  many times before exiting. If count is not specified then
       fnotifystat will run until it is stopped.

       Note that if no file activity has occured  during  a  sample  delay  period  then  no  new
       statistics are output. The -f option will force output if desired.

       By  default,  fnotifystat  will  display  the  following  statistics  every sample 'delay'
       seconds:

       · Average number of opens, closes, reads and writes over the sample period

       · Average number of opens over the sample period

       · Average number of closes over the sample period

       · Average number of reads over the sample period

       · Average number of writes over the sample period

       · Process ID

       · Pathname

       The -I option will display the device (major, minor)  number  and  inode  instead  of  the
       filename while the -I option will just show the device (major, minor) number.

       The -c option will display the cumulative count of the open, close, read and writes rather
       than the averages.

OPTIONS

       fnotifystat options are as follow:

       -c     dump cumulative totals over all time rather than totals over each sample period.

       -d     strip full directory path off the filenames.

       -f     force statistics output even if no file  activity  has  occurred  during  the  last
              sampling period.

       -D     order  statistics  by  unique  device.  Rather than ordering periodic statistics by
              unique filename, instead order them by unique device (major, minor)  number.   This
              allows one to see file activity on a per device basis.

       -h     show help

       -i     pathnames  to include in filename activity. By default, all mounted filesystems are
              monitored, however, this may produce to much information.  The -i option allows one
              to provide a comma separated list of just the specific paths to monitor.

       -I     order  statistics  by  unique  device  and  inode.   Rather  than ordering periodic
              statistics by unique filename, instead order them by unique device  (major,  minor)
              and inode number.

       -m     merge  events.  The  default  -v  verbose  output  will  show  all  new events that
              fnotifystat detects on a file by a specific process. The -m option will  merge  all
              consecutive  events that occur on the same file from the same process to reduce the
              amount of event output.

       -n     no periodic statistics, just verbose mode  only.   Do  not  display  periodic  file
              activity statistics, but just show the verbose mode -v file activity.

       -p proclist
              monitor  specific  processes.  proclist is a comma separated list of process IDs or
              process names to monitor.

       -P     sort stats by pid first, then by totals and filename

       -s     turn off data scaling. By default the  read,  write,  open  and  close  counts  are
              displayed  by  scaling  by  multiple of thousands with suffixes of K (thousands), M
              (millions),  B  (billions).   The  -s  option  disables  this,  resulting  in  less
              aesthetically pleasing unaligned columns of data.

       -t N   only display the top busiest N files.

       -T     show timestamp

       -v     verbose  mode,  dump all file activity. This will display the following file access
              information:

              Date (in DD/MM/YY format)
              Time (in HH:MM:SS format)
              Event count
              Access type, O=Open, C=Close, R=Read, W=Write
              Process ID
              Process Name
              Name of accessed file

              Note that the names of deleted filenames cannot be determined and  are  flagged  by
              the "(deleted)" tag.

       -x     pathnames  to  exclude  from filename activity. By default, all mounted filesystems
              are monitored, however, this may produce to much information.  The -x option allows
              one  to  provide  a  comma  separated  list  of  pathnames to exclude.  Matching is
              performed on partial pathnames, for example -x /pro will exclude all paths starting
              with  /pro,  such  as  /proc.   Note  that  excluding  a  file with -x takes higher
              precedence over including a file with -i.

       SIGUSR1
              Sending SIGUSR1 to fnotifystat will toggle the verbose option (-v) on/off.

EXAMPLES

       Show file activity every second until stopped.
               sudo fnotifystat

       Show the top 10 active files every 60 seconds until stopped.
               sudo fnotifystat -t 10 60

       Show file acivity every 10 seconds just 6 times.
               sudo fnotifystat 10 6

       Show file activity of thunderbird and process ID 1827.
               sudo fnotifystat -p thunderbird,1827

       Show every file notify event and the top 20 active activity files over a single period  of
       5 minutes.
               sudo notifystat -v -d -c 5m 1

       Just show every file notify event on /sys and /proc and no periodic statisics.
               sudo fnotifystat -n -i /sys,/proc
