Chapter 2. JBoss ON Managed Fuse Resources
Overview
Metrics are collected for managed resources that are deployed in Red Hat JBoss Fuse.
- Apache ActiveMQ managed resources
- Apache Camel managed resources
- Apache CXF managed resources
- JBoss Fuse managed resources
- Fuse Fabric managed resources
Note
This guide descibes the metrics collected on Apache Camel, Apache CXF, JBoss Fuse, and Fuse Fabric managed resources only. The Performance Metrics Reference for Red Hat JBoss A-MQ describes the metrics collected on Apache ActiveMQ-managed resources.
Important
Newly added resources, such as ActiveMQ queues and topics, will not appear in JON's list of resources until the JON agent discovers and adds them into inventory. By default, the agent scans for services at twenty-four hour intervals, but you can easily change the default interval either through the JON console or by resetting it in the agent's configuration file. For details, see Setting Discovery Scan Intervals in the Configuring JBoss ON Servers and Agents guide at https://access.redhat.com/site/documentation/.
Based on a managed resource's metrics, you can invoke Control Operations on the resource to avoid or correct throughput and performance problems.
Availability Status
For all JBoss Fuse managed resources, this metric is of category Availability and of measurement type Dynamic. It indicates the availability status of a resource during a given time slice.
| Icon | State | Description |
|---|---|---|
 | Available (Up) | Resource is running and responding to availability checks. |
 | Down | Resource is not responding to availability checks. |
 | Unknown |
The agent has no record of the resource's state.
This could be due to the resource having been newly added to inventory, so has not yet been checked for availability. Or it could be that the agent is down.
|
 | Disabled |
The resource has been administratively marked as unavailable.
In reality, the resource could be running or stopped. When a resource is disabled, the server ignores availability reports from the agent to prevent unnecessary alerts triggered by known down (or cycling) states.
|
 | Mixed (resource groups only) | Members in a resource group have different availability states. |
Per Minute metrics
Because metrics of type Trends Up and category Throughput continuously increase, the rate of change becomes more important to track than the total number of exchanges. So JBoss ON automatically calculates and creates a secondary Per Minute metric for many of these type of exchanges. By default, the Per Minute metrics, rather than their counterparts, are enabled and charted.
Referencing properties in Dynamic Group Definition expressions
To reference configuration properties and traits in Dynamic Group Definition expressions, you must use the item's internal name.
