RHV - Overview

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.

Creating a new RHV Monitor Group

Supported Versions: RHV 4.2 version and above.

Prerequisites for monitoring RHV metrics: Click here

Using the REST API to add a new RHV monitor: Click here

1. Go to New Monitor → Add New Monitor → Virtualization category → RHEV Virtual Infrastructure monitor type.
2. Specify the Display Name of the RHV server.
3. Enter the Host Name or the IP Address of the host where the RHV server is running.
4. Enter the User Name and Password for authentication.
5. Enter the Port where the server is running.
6. Select the VM Discovery option. The available options are Do not discover, Discover VM but do not monitor metrics, and Discover and Monitor VM metrics.
7. Specify the Polling Interval in minutes.
8. If you are adding a new monitor from an Admin Server, select a Managed Server.
9. Choose the Monitor Group with which you want to associate the RHV server from the Select the Monitor Group combo box (optional). You can choose multiple groups to associate your monitor.
10. Click on the Fetch Hosts button. This discovers the RHV server from the network and starts monitoring it.

User Permissions

We recommend to use the admin privilege account to monitor the RHV server.

Monitored Parameters

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:

• Availability tab gives the Availability history of the RHV server in the past 24 hours or 30 days.
• Performance tab gives the Health Status and events for the past 24 hours or 30 days, some key performance indicators of the RHV server such as CPU Utilization and Memory Utilization along with heat charts for these attributes.
• List view enables you to perform bulk admin configurations and displays all the RHV servers along with an overall idea of their availability and health status.

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:

• Overview
• Memory
• Network
• Configuration

Overview

This tab provides a high-level overview of the performance and availability of the RHV server.

Memory

This tab provides details about the memory usage of the RHV server.

Network

This tab provides details about the network utilization of the RHV server.

Configuration

This tab provides the configuration details of the RHV server.
