How to get the coverage report for Jenkins Jobs

[Wu Xun]

Dear Jenkins Managers,

We are currently using Jenkins for a lot of our testing jobs, but one problem we are finding is that, when we try to make the Restcall for that Jenkins jobs by adding "api/json?pretty=true" it will list the healthreport there, but the healthreport score is different from what is showing on the Jenkins html page, So I am wondering what is the score means in the api/json page and what restcall should I use to get the numbers in html page.

I have attached the screen shot for the job I have.

Thanks

Xun
