Ambari-metrics-monitor works inappropriately

[Dongkyu Hwangbo <hw...@gmail.com>]

Hi. 
I installed Ambari 2.5 by building source. and then, add ambari.repo file to my /etc/yum.repos.d.

ambari.repo:
#VERSION_NUMBER=2.4.2.0-136

[Updates-ambari-2.4.2.0]
name=ambari-2.4.2.0 - Updates
baseurl=http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/2.4.2.0
gpgcheck=1
gpgkey=http://public-repo-1.hortonworks.com/ambari/centos7/RPM-GPG-KEY/RPM-GPG-KEY-Jenkins
enabled=1
priority=1


afther that, I add a ambari-metrics service with ambari server web-console. but any metrics is unavailable. How can I solve this problem?
My every node is already done
  - Reverse dns setting 
  - add my every host and ip to /etc/hosts.
