RRDLAST(1) rrdtool RRDLAST(1)

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.

filename
The 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 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

ENVIRONMENT VARIABLES

The following environment variables may be used to change the
behavior of "rrdtool last":

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.
