rrdlast - Return the date of the last data sample in an RRD

The l\bla\bas\bst\bt function returns the UNIX timestamp of the most recent update
_\bf_\bi_\bl_\be_\bn_\ba_\bm_\be
The name of the R\bRR\bRD\bD that contains the data.
+ -\b--\b-d\bda\bae\bem\bmo\bon\bn _\ba_\bd_\bd_\br_\be_\bs_\bs
+ Address of the rrdcached daemon. If specified, a "flush" com-
+ mand is sent to the server before reading the RRD files. This
+ allows r\brr\brd\bdt\bto\boo\bol\bl to return fresh data even if the daemon is con-
+ figured to cache values for a long time. For a list of
+ accepted formats, see the -\b-l\bl option in the rrdcached manual.
+
+ rrdtool last --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

+ The following environment variables may be used to change the behavior
+ of "rrdtool last":
+
+ R\bRR\bRD\bDC\bCA\bAC\bCH\bHE\bED\bD_\b_A\bAD\bDD\bDR\bRE\bES\bSS\bS
+ 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.
