RRDINFO(1)                          rrdtool                         RRDINFO(1)



NNAAMMEE
       rrdinfo - extract header information from an RRD

SSYYNNOOPPSSIISS
       rrrrddttooooll iinnffoo _f_i_l_e_n_a_m_e [----ddaaeemmoonn|--dd _a_d_d_r_e_s_s [----nnoofflluusshh|--FF]]

DDEESSCCRRIIPPTTIIOONN
       The iinnffoo 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.

       _f_i_l_e_n_a_m_e
               The name of the RRRRDD you want to examine.

       ----ddaaeemmoonn|--dd _a_d_d_r_e_s_s
               Address of the rrdcached daemon. If specified, a "flush"
               command is sent to the server before reading the RRD files.
               This allows rrrrddttooooll 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 --ll option in the rrdcached manual.

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

       ----nnoofflluusshh|--FF
               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.

       This is the output generated by running iinnffoo on a simple RRD which
       contains two data sources and one RRA. Note that the number after the
       _l_a_s_t___u_p_d_a_t_e keyword is in seconds since 1970. The string NNaaNN stands for
       _*_U_N_K_N_O_W_N_* data. In the example it means that this RRD has neither
       minimum nor maximum values defined for either of its data sources.

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

       RRRRDDCCAACCHHEEDD__AADDDDRREESSSS
           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.
