Pre-requisites for Monitoring RHEV

General Pre-requisites

  • Enable the remote agent to communicate with the eG manager port (default: 7077).

  • If VMs running on multi-byte operating systems are to be monitored (eg., Windows Japanese), then the remote agent monitoring such VMs should also run on a multi-byte operating system.

  • 32-bit VMs that are to be monitored in an agentless manner should be configured with at least 2 GB RAM, and 64-bit VMs require at least 4 GB RAM. If more than four RHEV Hypervisors are being monitored in an agentless manner, then the RAM capacity of the VMs should be increased proportionately.

Pre-requisites for Obtaining the "Outside View" of VMs by connecting to the RHEV Manager

  • Ensure that the remote agent has IP connectivity to the RHEV manager.

  • Ensure that the remote agent has HTTP/HTTPS access to the port (port 8080/8443) at which the RHEV manager listens

  • All the tests that the remote agent executes should be configured with the name and password of a user with read-only access to the REST API of the RHEV manager. To know how to configure a read-only role on the RHEV manager and assign that role to a user, follow the steps detailed in Configuring the eG Agent to use the RESTful APIs on the RHEV Manager to Obtain the “Outside View” .

Pre-requisites for Obtaining the "Inside View" of VMs

  • Install a light-weight software called eG VM Agent on each VM. For details on how to install the eG VM Agent, refer to Configuring the Remote Agent to Obtain the Inside View of VMs.

  • Enable the remote agent to communicate with the port at which the eG VM Agent listens (default port: 60001).

  • Set the Inside View Using flag for all the “inside view” tests to eG VM Agent
