rrdlast(1) rrdtool rrdlast(1)
NAME
rrdlast - Return the date of the last data sample in an RRD
SYNOPSIS
rrdtool last filename [--daemon 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 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.
