Graphically monitor CPU - RAM etc over ROS
Hi,
I am using an ODROID-XU4 on a quadrotor. On the ODROID is running ROS. To the Odroid is also connected to a camera flea3 by PointGrey. I am launching the pointgrey node to connect to the camera and it is working fine.
I am not sure but it seems that when I increase the frequency of acquisition of the camera (from 30 Hz and greater) the quadrotor becomes a bit unstable. It does not happen all the time but sometime. Because I don't know where this behavior is coming from I thought that it could come from the CPU/RAM which are working too much.
For this reason I was thinking if there is some tool which enables to store a rosbag file which then can be easily plotted to check the allocation of RAM and CPU when the frequency changes.
Thanks in advance for your help.
