Oracle Coherence Servers Monitoring

Overview

Applications Manager provides out-of-the-box performance metrics and helps you visualize the health and availability of an Oracle coherence server farm. Using the Oracle Coherence monitoring utility provided by Applications Manager, will help to obtain a deep insight into health and performance of complex Coherence implementations. Database administrators can login to the web client and visualize the status and Oracle coherence performance metrics.

Creating a new Oracle Coherence Monitor

Supported Versions: Oracle Coherence 14.1.x and below

Prerequisites for monitoring Oracle Coherence metrics: Ensure that you enable JMX for Oracle Coherence monitoring. For you to create a new Oracle Coherence monitor, you should have admin privileges.

Using the REST API to add a new Oracle Coherence monitor: Click here

Click on New Monitor link.
Select Oracle Coherence.
Enter the Display Name of the monitor
Enter the IP Address or hostname of the host.
Enter the JMX Port in which the JMX is running.
Enter the Additional JMX Port in which the JMX is already running in any of the other machine of the same cluster.
Choose the Credential Details either use below credentials or select from credential list
Enter the Username and Password.
Enter JNDI Path (eg.) /jmxrmi
Enter the polling interval time in minutes.
Choose the Monitor Group from the combo box with which you want to associate Oracle database server Monitor (optional). You can choose multiple groups to associate your monitor.
Click Add Monitor(s). This discovers Oracle database server from the network and starts monitoring them.

Note:

To create a new Oracle Coherence monitor, you should have admin privileges.
Jconsole can also be used to access the Mbeans.
In case you are unable to add the monitor even after enabling JMX, try providing the below argument:
-Djava.rmi.server.hostname=[YOUR_IP]

Monitored Parameters

Availability tab gives the Availability history for the past 24 hours or 30 days.
Performance tab gives the Health Status and events for the past 24 hours or 30 days.
List view enables you to perform bulk admin configurations.
