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.- filename
- The name of the RRD that contains the data.

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
