[rrd-users] GSoC 2014 - an R package for working with RRD files

[Steve Shipway]

It's great to have support for RRDTool in more languages.

Are you going to add support for calling the RRDTool standard library functions, to create graphs or update the data?

Subject: [rrd-users] GSoC 2014 - an R package for working with RRD files

Hello,

I spent the past few months implementing an R package that makes it possible to directly import and work with RRD files in R.

There are currently three ways to use the package:

- importRRD("filename", "cf", start, stop, step) - returns a data.frame containing the desired portion of an RRA
- importRRD('filename") - imports everything in the RRD file into a list of data.frame objects (one per RRA)

(the metadata is read and appropriate names are given to columns and list elements)

- getVal("filename", "cf", step, timestamp) - optimized for getting the values at a specific timestamp, uses a cache to minimize the read frequency

Please, feel free to install and test the package: https://github.com/pldimitrov/Rrd

I'm now getting close to finishing it so any feedback is more than welcome!

Thanks,
Plamen
