NAME

rrdlast - Return the date of the last data sample in an RRD

SYNOPSIS

rrdtool last filename [--daemon|-d address]

DESCRIPTION

The last function returns the UNIX timestamp of the most recent update of the RRD.

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