I have a job that is taking a very, very long time to complete. I want to understand why.
When I look at the job’s execution history, I can see the job’s runtime under the “Overview” panel and information on the components under the “Tracking” panel.
The “Tracking” panel show lots of interesting information, but it doesn’t show the “wall clock” time each component was running for.
How can I get these component “wall clock” times?
More generally speaking, how should I profile my jobs for performance issues like this?
