Agent Deployment Models

As mentioned earlier, administrators can choose between the agent-based and agentless approaches to Citrix Hypervisor monitoring. In case of the “agent-based” approach, a single eG agent deployed on the control domain (i.e., Domain 0) of the Citrix Hypervisor can be configured to monitor the host and each of the guest operating systems executing on it. The control domain of the Citrix Hypervisor runs a Linux variant. Hence, the eG agent for Linux should be deployed on the Citrix Hypervisor. When installing the eG agent, make sure that you have at least 350MB of free disk space on Domain 0. The procedure for deploying the eG agent on the control domain is exactly the same as the process for installing the eG agent on Linux, which is described in the eG Installation Guide.

In case of the “agentless” approach, an eG agent deployed on a remote Windows or Linux host in the environment can be configured to monitor the loading of the physical Citrix Hypervisor, the relative loading of each of the guests on the server, and how well each guest is using the resources allocated to it. Refer to the eG Installation Guide for a detailed procedure on how to install and configure an eG agent on Windows/Linux.

To obtain the 'inside view' of each of the VMs, you need to deploy a piece of software called the eG VM Agent on every VM. Refer to Configuring the Remote Agent to Obtain the Inside View of VMs for more details on the eG VM Agent.
