Managed Instances
Click Managed instances to view the table of managed instances for the selected fleet. The table presents a list of managed instances that have reported the presence of a Java installation or the start of a Java application.
For each managed instance, the table presents the following information:
- Host: name of the host associated with the managed instance
- Agent status: status of the agent
- Initializing: the agent has registered with JMS, but it's in a transitory state until it is fully functional. An agent can remain in this state up to 15 minutes, and if this state persists, this could imply a communication error between the agent and the agent service.
- Active: the agent service is communicating with the agent, and the agent is functioning as expected.
- Silent: the agent service isn't communicating with the agent. While communication was established after the agent installation, there currently might be a communication problem between the agent service and the agent.
- Deleted: the management agent or the compute instance have been deleted or the agent has been deleted from the Java Management service console. In the latter case, the agent might be running but isn't functional because it isn't attached to any fleet.
- Moved: the agent has been moved to another fleet.
- Unregistered: an agent that was associated to a fleet but was detached due to lack of activity.
- Needs Attention: the agent is not functioning properly or is misconfigured.
- Agent state: specifies the agent security state, such as Update available
- OCID: OCIDs of the managed instances in the fleet that have Java installation or Java application started at the selected time period
- Java runtime installations: number of Java applications installed on the managed instance at the selected time period
- Applications: number of applications installed on the host at the selected time period
- Deployed applications: number of application deployed on the Java server at the selected time period
- Operating system: operating system of the host, such as Windows, Linux
- First reported: date and time when the managed instance was first reported
- Last reported: date and time when the managed instance was last reported
