NAME
rrdinfo - extract header information from an RRD
SYNOPSIS
rrdtool
info
filename.rrd
DESCRIPTION
The
info
function prints the header information from an RRD in
a parsing friendly format.
Check
././rrdcreate.html
the rrdcreate manpage
if you are uncertain about the meaning of the
individual keys.
EXAMPLE
This is the output generated by running
info
on a simple RRD which
contains two data sources and one RRA. Note that the number after the
last_update
keyword is in seconds since 1970. The string
NaN
stands for
*UNKNOWN*
data. In the example it means that this RRD
has neither minimum nor maximum values defined for either of its
data sources.
filename = "random.rrd"
rrd_version = "0001"
