This post summarizes the progress in the tenth week of the coding period. Last week most of the time was spent on matching the output of pcp-mpstat. This week pcp-mpstat is merged and is to be included in the next version of the pcp.

Added archive

Considering all the required metrics, I created an archive with 4 samples, tested unittests on it and added it to /qa/archives/. This archive would be used for implementing the regression tests.

Added regression tests

After the code being ready to be merged, I created a new test (number 883) under qa/ directory using ./new. Added test cases and generated the out file using ./remake.

pcp-mpstat merged

Although a few new challenges had to be faced (like handling machine dependant interrupt metrics), experience from pcp-pidstat has been a lot useful for writing this command.

With this, comes an achievement of the second goal for GSoC, we have been able to finish the pcp version of mpstat command in a short time. A big shoutout to the mentors and community for their time and guidance.

That’s all folks.
