This is a general question and I am looking for tips and best practices.
What are some ROS/Linux commands and tools for measuring performance of a node or a system in ROS? (Beyond rostopic hz).
For example, do we have something similar to strace, written specifically for ROS nodes?
I typically use normal Linux tools like perf and flame graphs for performance analysis.
You can also use ftrace and catapult to find inter-thread and inter-process interactions that are creating performance bottlenecks.
Unless you're trying to look for performance problems specifically around interactions between nodes, or across a multi-machine ROS system, the standard Linux tools should do very well.
P.S. - I have not used strace as a performance measurement tool. It's fine for introspection, but doesn't seem well suited to measuring performance.
