[rrd-users] Re: Graphing Total Bandwidth

[Stephan Harren]

Hi Andre,

AFAIK, you've got to do this by yourself, for example in a little perl 
script:

Collect the data you need by rrdtool fetch, add the values to the total 
amount you want to be graphed and put it into a rrd-database (use GAUGE 
as DS-Type). Then you can graph them.
Every hour: collect the values for the last hour, add them and put the 
sum into your database for hourly graphs. Be sure to have the database 
have a resolution of one hour.
Every day: collect the values for the last day, add them and put the sum 
into your database for daily graphs. Be sure to have the database have a 
resolution of one day.
Every month: collect the values for the last month, add  them and put 
the sum into your database for monthly graphs. Be sure to have the 
database have a resolution of one month.
Graph them with the exact timeframe you want to have, because you don't 
have a higher resolution than you want to have, there will be no 
consolidation and the values you inserted will be graphed exactly.


Another thing  you can do is to fetch the stuff and write a 
comma-separated file, import it into excel or whatever office and do a 
bar-graph there (wouldn't prefer this solution). The thing is, that 
rrdtool can only calculate single values to be graphed.

Pls let me know if anyone finds a better solution.

Best regards,

Stephan
