Resource Discovery and Monitoring Overview
Resource Discovery and Monitoring auto-discovers and monitors the applications (resources) running on Oracle Linux Compute instances. It does this by periodically checking running processes and identifying the type of application to which it belongs. Then it starts monitoring its state, overall CPU Utilization and Memory Utilization. The set of application (resource) types supported are Oracle Database, Oracle Database Listener, WebLogic Server, Oracle HTTP Server, Apache Server, Tomcat, and MySQL.
Resource Discovery and Monitoring only supports OCI Linux instances supported by the OS Management service, except OCI Linux for ARM (AArch64) instances. OCI Windows instances are not supported at this time.
Using the Monitored Resources page, you can monitor the applications' current State, Memory Utilization and CPU Utilization as well as review its historical trends. You can also quickly see how CPU and Memory Utilization for an application changed compared with the same time last week.
You can set alarms and notifications when CPU Utilization or Memory Utilization of any of these resources exceed specified thresholds.
If you enable the integration with Java Management Service, then, for resource types that use Java (Tomcat and WebLogic Server), you will be able to identify their associated Java Runtime versions as well as their security state.
If CPU or Memory Utilization on the compute is high, and these are not due to the discovered applications, you can use the Top Processes page to identify the top 10 processes running on the Compute instance that are consuming the greatest amount of CPU and memory, thus allowing you to quickly pinpoint the cause of high resource consumption.
Once Resource Discovery and Monitoring is set up, you can begin monitoring the resources running on OCI Compute instances.
