Manual
RRDLAST
NAMESYNOPSIS
DESCRIPTION
ENVIRONMENT VARIABLES
AUTHOR
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.
