RRDLASTUPDATE(1)                     rrdtool                    RRDLASTUPDATE(1)

NAME
     rrdlastupdate - Return the most recent update to an RRD

SYNOPSIS
     rrdtool lastupdate filename [--daemon|-d address]

DESCRIPTION
     The lastupdate function returns the UNIX timestamp and the value stored for
     each datum in the most recent update of an RRD.

     filenameThe name of the RRD that contains the data.

     --daemon|-d address
             Address of the rrdcached daemon. If specified, a "flush" command is
             sent  to  the server before reading the RRD files. This allows rrd‐
             tool to return fresh data even if the daemon is configured to cache
             values for a long time.  For a list of accepted formats, see the -l
             option in the rrdcached manual.

              rrdtool lastupdate --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

ENVIRONMENT VARIABLES

     "rrdtool lastupdate":

     RRDCACHED_ADDRESS
         If  this  environment  variable  is set it will have the same effect as
         specifying the "--daemon" option on  the  command  line.  If  both  are
         present, the command line argument takes precedence.
