Red Hat Virtualization (RHV) is an open, software-defined platform that visualizes Linux and Microsoft Windows workloads. The RHV infrastructures are based on KVM hypervisor (Kernel-based Virtual Machine) and features management tools that provides resources, processes, and applications to ensure service performance and business continuity.
Applications Manager lets you perform precise hierarchical service topology mapping of all aspects of the RHEV hypervisor and RHEV guest VMs, where admins can set up a consistent monitoring system, control user experience and improve real-time performance of mission critical business services in the RHV cluster.
Supported Versions: RHV 4.2 version and above.
Using the REST API to add a new RHV monitor: Click here
We recommend to use the admin privilege account to monitor the RHV server.
Go to the Monitors Category view by clicking the Monitors tab. Click on RHV under the Virtualization table. Displayed is the RHV bulk configuration view distributed into three tabs:
RHV servers are monitored based on the parameters or the attributes listed below. These attributes provide information about the functioning of the monitors of the RHV server. In addition, you can configure thresholds to the numerical attributes monitored by the server based on these details.
Click on the monitor listed to view detailed performance metrics of the RHV server. These metrics are categorized into four different tabs for easy understanding. Below is an explanation of the metrics shown in these tabs:
This tab provides a high-level overview of the performance and availability of the RHV server.
