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.
