RRDINFO(1)                          rrdtool                         RRDINFO(1)



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 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"
        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 examine.
