NAME

6       rrdinfo - extract header information from an RRD
7

SYNOPSIS

9       rrdtool info filename.rrd
10

DESCRIPTION

12       The info function prints the header information from an RRD in a
13       parsing friendly format.
14
15       Check rrdcreate if you are uncertain about the meaning of the
16       individual keys.

EXAMPLE

19       This is the output generated by running info on a simple RRD which
20       contains two data sources and one RRA. Note that the number after the
21       last_update keyword is in seconds since 1970. The string NaN stands for
22       *UNKNOWN* data. In the example it means that this RRD has neither
23       minimum nor maximum values defined for either of its data sources.

51               The name of the RRD you want to examine.
