Hi there, I'm struggling to find the total time taken by a database query on the disk? As I understand when a database query start execution it takes some time inside the database engine & some time to seek the result from disk (if that is not in cache/buffer) Can anybody from the group please suggest any clue about the execution time on the disk? Many thanks Stdranwl
As stated in other emails you can use the performance_schema. Mark Leith has provided a stable version of ps_helper now called the sys schema and can be obtained on github here, https://github.com/MarkLeith/mysql-sys . There is quite a bit of help and examples in the README.md. Also you check into the experimental portion of it called dba helper also on github, https://github.com/MarkLeith/dbahelper . I think you will be able to find what you are looking for utilizing these tools that make performance schema much easier to use and under stand.
