I have researched many open source monitoring tools(ganglia,ELK stack,zabbix etc) to monitor existing Bigdata component cluster. I got some success with Ganglia and ELK for hadoop metrics only. I have to monitor other components also like hive,kafka,hbase,spark. I have used Ambari before also but that time i have installed all the components through ambari only.
This time i already have all the bigdata components installed/configured and i want to provision,manage and perform admin tasks through ambari GUI.
Is this possible with Ambari to monitor existing bigdata components ?
Can Takeover by Ambari work for cluster consisting of plain apache bigdata components also or for HDP only ?
