OMi Management Pack for Infrastructure2.00

Essential XEN Management Template

The Essential XEN Management Template monitors the resource usage for XEN host and individual guest systems. It monitors the basic functionalities of XEN virtualization environment - Guest availability and resources, Host resource utilization and discovers the virtual components like hypervisor host, guest, and resource pool. The Essential XEN Management Template comprises specific Aspects to monitor these features.

Note: You can deploy Essential XEN Management Template only on the host.

Management Template - Aspects

The Essential XEN Management Template consists of the following Aspects:

Xen Guest Health

The XEN Guest Health Aspect monitors the guest availability and resources in a virtualized XEN environment. This Aspect consists of the following policy templates:

CI Type	Policy Template	Indicator	Policy Description	Policy Type
Computer (Virtualization Layer Software)	Virt_LinuxHV_GuestCPUUtilMonitor	CPULoad	Monitors the CPU utilization of VMs within a host. The CPU utilization of each VM is checked against the threshold limits. In case of any violation, alerts are raised with the list of VMs on that host.	Measurement Threshold Template
	Virt_LinuxHV_StateMonitor	NodeStatus	Monitors and evaluates the KVM and Xen logical system which has any one of the states such as `nostate, running, run/idle, paused, shutdown, crashed,` or `shut off`. An alert is raised only if the VM is in the same transient state for more than 30 minutes.

Xen Host Health

The XEN Host Health Aspect monitors the host resource utilization in a virtualized XEN environment. This Aspect consists of the following policy templates:

CI Type	Policy Template	Indicator	Policy Description	Policy Type
Computer	Virt_LinuxHV_HostCPUUtilMonitor	CPULoad	Monitors the host CPU utilization for KVM and Xen systems in a virtualized environment. The CPU bottleneck symptom is indicated by high CPU utilization rate in the host system.	Measurement Threshold Template
	Virt_LinuxHV_HostMemoryUtilMonitor	MemoryUsageLevel	Monitors the physical memory utilization of hosts in Linux virtualization environment. The memory bottleneck symptom is indicated by high memory utilization rate along with low available memory.

Virtual Infrastructure Discovery

The Virtual Infrastructure Discovery Aspect discovers the virtual components such as hypervisor host, guest, and resource pool in a virtualization environment. This Aspect consists of the following policy template:

CI Type	Policy Template	Indicator	Policy Description	Policy Type
Computer	Virt_Discovery	NA	Discovers the virtual infrastructure components like hypervisor host, guest, and resource pool in a virtualization environment.	Service Auto-Discovery Template
