The virtualization monitor is a specialized variation of the usage monitor mechanism that provides monitoring functionality specific to virtualization-related usage. A variety of virtualization monitors can be used to perform different forms of monitoring. Virtualization monitors are typically implemented as service agents.
Figure 1 shows a hypervisor cluster being monitored by a virtualization monitor as part of the virtual infrastructure monitor as follows:
- Hypervisors are installed on the three physical servers.
- Virtual servers are created by the hypervisors.
- A shared cloud storage device containing virtual server configuration files is positioned so that all hypervisors have access to it.
- The hypervisor cluster is enabled on the three physical server hosts via a central VIM, and monitored by the VIM’s virtualization monitor function.
