RRDINFO(1)                   rrdtool                   RRDINFO(1)


NAME
       rrdtool info - 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 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 datasources 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 not
       maximum values defined for either of its datasources.

        filename = "randome.rrd"
        rrd_version = "0001"
        step = 300
        last_update = 955892996
        ds[a].type = "GAUGE"
        ds[a].minimal_heartbeat = 600
        ds[a].min = NaN
        ds[a].max = NaN
        ds[a].last_ds = "UNKN"
        ds[a].value = 2.1824421548e+04
        ds[a].unknown_sec = 0
        ds[b].type = "GAUGE"
        ds[b].minimal_heartbeat = 600
        ds[b].min = NaN
        ds[b].max = NaN
        ds[b].last_ds = "UNKN"
        ds[b].value = 3.9620838224e+03
        ds[b].unknown_sec = 0
        rra[0].cf = "AVERAGE"
        rra[0].pdp_per_row = 1
        rra[0].cdp_prep[0].value = nan
        rra[0].cdp_prep[0].unknown_datapoints = 0
        rra[0].cdp_prep[1].value = nan
        rra[0].cdp_prep[1].unknown_datapoints = 0


       filename.rrd
               The name of the RRD you want to dump.
