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.
