Monitoring Resource Manager
Resource Manager provides self-monitoring capabilities. A visual pipeline-based status page in the browser interface shows an overview of the monitored Resource Manager instance, including key metrics for nodes in the metric collection, event generation, and modeling processes.
Resource Manager monitoring listens to events in the event class /ZenossRM. Each pipeline includes nodes and aggregate data for the associated components. Events on monitored components are used to flag a data pipeline node for your investigation. When a threshold violation occurs, the node changes from green to flashing gray, as shown by the metricshipper node in the figure. To open the detail page for the associated component, click a node in a pipeline.
Use data to troubleshoot performance issues with Resource Manager components and proactively manage performance. For example, data can help you determine when a component or service in the system is overloaded. Before issues occur, optimize system performance by adding more instances, more memory, more CPU, or adjusting configuration settings.
The Resource Manager installation or upgrade process creates device class /ZenossRM, and creates and models the local Resource Manager device with ID 127.0.0.1. Locally stored metrics for the monitored device provide detailed performance tracking for Resource Manager components.
You can add multiple Resource Manager instances as devices. Monitor the health and performance of multiple Resource Manager and Control Center instances from the same or another Resource Manager instance. You can monitor remote Resource Manager instances on the same Control Center and remote Resource Manager instances that are on a different Control Center.
