       RRDcollect  --  Round-Robin Database Collecting Daemon.


       rrdcollect [option]...


       The rrdcollect daemon is responsible for fetching statistical data from
       various soures  (listed  in  rrdcollect.conf),  typically  files  under
       /proc/ directory.  It periodically reads them and searches for patterns
       from configuration file.  Values are then stored inside rrdtool’s  .rrd


       RRDcollect follows the usual GNU command line syntax, with long options
       starting with two dashes (‘-’).

   General options
       -c file
           Specifies which file should be read instead of default config file.

           Program will not fork.  Very useful when testing or debugging.

           Increase  verbosity.  This option also implies --no-fork, since you
           probably  don’t  want  RRDcollect  in  daemon  mode  trashing  your

   RRD update options
       -o file
           Specifies   file  to  which  rrdtool(1)-style  commands  should  be
           written.  If file you specify is ‘-’  (hyphen),  then  commans  are
           written to standard output (this case implies --no-fork).

           When  this  option is used, RRDcollect will open pipe to rrdtool(1)
           program and send it update commands.  If you  don’t  give  program,
           the  compiled-in  default is assumed (either ‘rrdtool - >/dev/null’
           or full path to rrdtool(1) binary).   The  program  option  can  be
           specified as a full path or just a command name, in the latter case
           the program should reside on PATH.

       If no RRD update option  is  given,  RRDcollect  uses  internal  librrd
       routines  (the  preferred  mode  of  operation).   If RRDcollect is not
       compiled with librrd, then it will fall back to pipe-mode.
