Oracle NoSQL Servers

Monitored Parameters

Applications Manager provides out-of-the-box performance metrics and helps you visualize the health and availability of an Oracle NoSQL server farm. Database administrators can login to the web client and visualize the status and Oracle NoSQL performance metrics.

 


Note:

  • To create a new Oracle NoSQL monitor, you should have admin privileges. 
  • Jconsole can also be used to access the Mbeans
