Recently, I am using percona-toolkit. One of tools is pt-trend. It is used likept-trend mysql-slow, and it’s output as followings:
- 1344442759 1.000000 0.004988 0.004988 0.004988 0.004988
- 1344442763 2.000000 1.124892 0.000889 1.124003 0.562446
- 1344442764 133.000000 1.609606 0.000284 1.483041 0.012102
What does each column mean? I can’t find information on the percona official docs.
