Citrix Hypervisor (XenServer)


Overview

Applications Manager provides monitoring support and virtual machine management of your Citrix Hypervisor (formerly XenServer) infrastructure with a comprehensive view into individual components. You can monitor Citrix Hypervisor host metrics, virtual machines metrics for your Citrix Hypervisor Host and capture XenMotion under Resource Pools for easier management of hosts and to detect performance problems.

The key performance metrics monitored by Applications Manager include those pertaining to CPU usage, memory usage, storage details, network utilization and configuration info at both the Citrix Hypervisor host and VM level. Once the host is added, the virtual machines are auto-discovered. You can receive immediate notification with historical reporting of VM performance to enable the rapid diagnosis of problems in your virtual infrastructure.

Creating a new Citrix Hypervisor monitor

Supported versions: Citrix Hypervisor 5.6 and 6.2

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

Follow the steps given below to create a new Citrix Hypervisor monitor:

  1. Click on New Monitor link.
  2. Select Citrix Hypervisor under Virtualization category.
  3. Specify the Display Name of the Citrix Hypervisor.
  4. Enter the Host Name or IP Address of the host where the Citrix Hypervisor runs.
  5. Enter the Https Port where the Citrix Hypervisor web service runs. The default port is 443.
  6. Enter the credential details like user name and password for authentication, or select the required credentials from the Credential Manager list by enabling the Select from Credential list option. It should be the credentials of any Citrix Hypervisor Host user with admin privileges.
  7. Select the VM Discovery option. Available options are Do not discover, Discover VM but do not monitor metrics, and Discover and Monitor VM metrics.
  8. Specify the Polling Interval in minutes.
  9. Choose the Monitor Group with which you want to associate the Citrix Hypervisor to, from the combo box (optional). You can choose multiple groups to associate your monitor.
  10. Click Add Monitor(s). This discovers the Citrix Hypervisor from the network and starts monitoring it.

Citrix Hypervisor resource pool discovery

Applications Manager automatically discovers the slave Citrix Hypervisor Hosts under the Resource Pool when adding the Master Citrix Hypervisor Host. Once the Master host is added, the resource pool will be discovered and added as a monitor group. The user must provide the credentials for the slave Citrix Hypervisor Host and manage the Citrix Hypervisor Host to collect the performance metrics. Adding a Slave Citrix Hypervisor Host is equivalent to a standalone Citrix Hypervisor Host and Applications Manager will not determine the master and other slave Citrix Hypervisor Hosts.

Monitored Parameters

  • Availability tab shows the availability history of Citrix Hypervisor for the past 24 hours or 30 days.
  • Performance tab shows some key performance indicators of the Citrix Hypervisor such as Response time, Total CPU Utilization along with heat charts for these attributes. This tab also shows the health status and events for the past 24 hours or 30 days.
  • List view lists all the Citrix Hypervisor servers monitored by Applications Manager along with their overall availability and health status. You can also perform bulk admin configurations from this view. Click on the individual servers listed to view detailed performance metrics.
  • Top Citrix Hypervisor tab shows graphs for the top total CPU utilization consumers, top guest CPU utilization consumers, top memory consumers and top idle CPU utilization consumers.

Citrix Hypervisor Resource Pool discovery

Applications Manager automatically discovers virtual elements within the environment - including Resource Pools, physical hosts, and VM guests. The Resource Pool will be automatically discovered when the Master Citrix Hypervisor Host is added.

Once the Master Citrix Hypervisor host is added, the Resource Pool will be discovered and added as a monitor group. All the slave Citrix Hypervisor hosts under the resource rool will be discovered automatically and all the Citrix Hypervisor Hosts (both Master & Slaves) will be mapped to the Resource Pool.

Note:

The discovered slave Citrix Hypervisor hosts are added in 'UnManaged' state. To associate/dissociate any monitors to this Resource Pool, the user must provide the credentials for the Slave Citrix Hypervisor Host and change it to managed state. After providing the credentials, Applications Manager discovers the virtual machines under the slave Citrix Hypervisor Host and collects performance metrics.

The Resource Pool will have the separate details view which has the following list of information:

  • Master Citrix Hypervisor Host and list of Slave Citrix Hypervisor Hosts.
  • Pool Configuration details.
  • VM and storage counts for all the hosts under the Resource Pool.

Click on the Resource Pool name under monitor groups to see the availability and health status of the pool, number of hosts, vms, storage and network.
