1.7.2                                              2025-03-04                                   RRDLASTUPDATE(1)

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

       filename
               The name of the RRD that contains the data.

       --daemon|-daddress
               Address  of  the  rrdcached  daemon. If specified, a "flush" command is sent to the server before
               reading the RRD files. This allows rrdtool 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

       The following environment variables may be used to change the behavior of "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.
