Current text is:

"Shows the running time of each completedtasks in this job(Each point represent a task)."

should be: "Shows the running time of each complete task in this job (each point represents a task)". Or if you like: "Shows the run time of each of the job's completed tasks. Each point represents a completed task. Red point means non-zero exit code."

Also, don't think it needs to be Italics, normal text would match the rest of the app.

And the link "tasks running time", should probably be "Task run time"
