I was wondering, if there is a program similar to time, but instead of just printing out the time it took to execute the command, it also prints out the average CPU and Memory usage. Alternatively a program which records the CPU and memory usage every couple of seconds and then writes it to a file would also work.

Any help is appreciated!

Thanks

Sysstat package is useful. You can customize how often and how many times to harvest the information. It consists tools for CPU usage , memory , processes. Also can store information in different formats

  1. iostat: Reports all statistics about your CPU and I/O statistics for I/O devices.
  2. mpstat: Details about CPUs (individual or combined).
  3. pidstat: Statistics about running processes/task, CPU, memory etc.
  4. sar: Save and report details about different resources (CPU, Memory, IO, Network, kernel etc..).
  5. sadc: System activity data collector, used for collecting data in backend for sar.
  6. sa1: Fetch and store binary data in sadc data file. This is used with sadc.
  7. sa2: Summaries daily report to be used with sar.
  8. Sadf: Used for displaying data generated by sar in different formats (CSV or XML).
  9. nfsiostat-sysstat: I/O statistics for NFS.
  10. cifsiostat: Statistics for CIFS.

  • Thanks alot! This looks like what I needed! Do you know if using this slows down the actual command?

  • As every process - will have an impact on the system but in normal case (if you are not on the edge of the resources) it won't affect the performance
