NAME
rrdlastupdate - Return the most recent update to an RRD
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.
--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 lastupdate --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 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.
