Generating report resource usage report for child processes

Question

I'm looking for a tool that would generate a report about child processes. I'm interested in CPU usage, memory usage, etc.

Ideally the tool would be used like this:

uber_reporter -o report.html command -command_param_1

What I'm looking for on the generated report are:

• Charts over time containing CPU usage, memory usage.
• The report should contain only parent and child processes started with command. I.e. I'm not interested in other processes.
• The legend should contain full invocation path of the process.
• The output format is not so important, HTML was used only as example. Output format could be source for GNU plot, image, PDF, etc.
  • In the simplest form such a report could be tabularized data (e.g. CSV).

Is there any such tool existing?

The system is Ubuntu Linux.
