about Yarn Cluster Metrics API's return value

daily
I confuse about Yarn Cluster Metrics API ( http://rm-http-address:port/ws/v1/cluster/metrics ), it does't get the correct info in my cluster.Did I misunderstand some properties?

(hadoop version=2.7.3)
1) The number of applications in my cluster is like below ( total=18) :
ACCEPTED 3
RUNNING 5
FINISHED 6
FAILED 4
KILLED 0

2) Yarn UI ( http://rm-http-address:port/cluster/apps ) info is like below (apps completed=7 ) :

3) I use Cluster Metrics API ( http://rm-http-address:port/ws/v1/cluster/metrics to get ) to get Yarn applications, the info is like below (apps completed=5 ) :

so, i get three different result.

Did I misunderstand some properties?

thanks.
Best regards.
