    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 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 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.
