       rrdtool info - extract header information from an rrd

[1mSYNOPSIS[0m

[1mDESCRIPTION[0m
       The [1minfo [22mfunction prints the header information from an rrd in a pars-
       ing friendly format.

       Check rrdcreate if you are uncertain about the meaning of the individ-
       ual keys.

[1mEXAMPLE[0m
       This is the output generated by running [1minfo [22mon a simple rrd which con-
       tains two datasources and one rra. Note that the number after the
       [4mlast_update[24m keyword is in seconds since 1970. The string [1mNaN [22mstands for
       [4m*UNKNOWN*[24m data. In the example it means that this rrd has neither mini-
       mum not maximum values defined for either of its datasources.
