Dear all, somebody knows how to open a .rrd file (round robin database file) with Matlab?. Thanks so much in advance. Alfredo

Im trying to analyze bandwith data from a communication link. This data is in rrd format.

You can use rrdtool to get the data of the rdd file into XML format.

>> rrdtool dump filename.rrd

Once the XML is generated, you can import the XML directly into MATLAB and extract the data from that XML file, and do further analysis (like time-series plots etc..)

See the following link for more information on reading XML file in MATLAB:

Thanks so much Nagarjuna. Im already download rrdtool application but have not enough skills to run rrdtool on my MAC.

Do you know what is the system environment that I need (on my MAC) and what command I need to execute >> rrdtool dump filename.rrd?

Thanks again Alfredo
