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.
