Real time data analysis, any tools or package inside ROS?

edit

Hello

Im wondering is there any tools or some packages inside ROS that permit real-time data analysis. I have used ROS in our mobile device , but I need to perform some online (real-time) analysis of the datas provided by my ROS nodes. Like speed profiles, distances to some object or obstacles , would like to be collected in long period of time, stored in some location and than in real-time (on-line) make them available for analysis. Is there any help inside ROS or do I need some additional Hardware and Software outside ROS??

Any help or comment would be welcome

Thanks
