[rrd-users] getting formatted output from rrdtool fetch

[Anant Tamgole]

Hi all,

How can get formatted output from "rrdtool fetch"

I used following command to create the rrd database (collecting in/out
bytes from cisco switch ports )

/usr/local/rrdtool-1.0.28/bin/rrdtool create switch.rrd \
DS:input:COUNTER:300:U:U \
DS:output:COUNTER:300:U:U \
RRA:AVERAGE:0.5:1:8928

I am using update command as follows:

rrdtool update N:$inbytes:$outbytes

Now when I try to fetch I get following output, which is not quote
readable.

rrdtool fetch switch.rrd AVERAGE                   
                    input        output


 984097200: NaN NaN
 984097500: 2.4100671141e+01 5.1861744966e+02
 984097800: 2.4100671141e+01 5.1861744966e+02
 984098100: NaN NaN
 984098400: 2.3885521886e+01 5.5295286195e+02
 984098700: 2.3221525028e+01 6.4252594299e+02
 984099000: 2.2458127048e+01 6.4225971358e+02
 984099300: 2.2437710438e+01 6.4218518519e+02

My requirements are:

1. input and output should be in Mbytes/sec ( no e+01 etc should be there)
2. Is it posssible to have local time instead of unix time
   Or how to convert unix time to local time.

Thanks in advance.
