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 the rrdcached manpage 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 the rrdcached manpage 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 rrdtoollast:

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.
