RRDINFO(1)                          rrdtool                         RRDINFO(1)

NAME
       rrdinfo - extract header information from an RRD

SYNOPSIS
       rrdtool info filename [--daemon|-d address [--noflush|-F]]

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.

       filename
               The name of the RRD you want to examine.

       --daemon|-d address
               Address  of  the  rrdcached  daemon.  If  specified,  a "flush"
               command is sent to the server before  reading  the  RRD  files.
               This  allows rrdtool to return fresh data even if the daemon is
               configured to cache values for a long  time.   For  a  list  of
               accepted formats, see the -l option in the rrdcached manual.

                rrdtool info --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

       --noflush|-F
               Omit  the  "flush"  command usually sent to the daemon prior to
               retrieving the data.  If all you are interested in is  the  RRD
               structure, and not the last update time or current values, then
               this will improve efficiency.

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
        header_size = 2872
        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

ENVIRONMENT VARIABLES
       The following environment variables may be used to change the  behavior
       of "rrdtool info":

       RRDCACHED_ADDRESS
           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.
