I got my ambari-server with Python 2.6 and Centos 6.8 and AMBARI VERSION is 18.104.22.168
I've installed a new host with Centos 7.2 comes with Python 2.7, on this host i've installed ambari-monitor.
With ambari GUI, I can't start Metrics Monitor, ths logs said OK, but not process starting
However I can start manually with this command :
/usr/sbin/ambari-metrics-monitor --config /etc/ambari-metrics-monitor/conf start root 10085 1 0 09:44 pts/0 00:00:16 /usr/bin/python2.7 /usr/lib/python2.6/site-packages/resource_monitoring/main.py start
Where I can check issue ?
When you attempt to start the service - in the task status window don't you see any errors? or else find out the task id and go to /var/lib/ambari-agent/data/output-XXX.out and .error files and see if it is giving any errors.
