Configuring XenServers

To monitor the Citrix XenServer environment, you must first create a connection between PATROL for Citrix XenServer and the Citrix XenServer environment. To do this, you need to add hosts (XenServers) to the Citrix XenServer environment. You can either add a resource pool master or a standalone host. When you add a resource pool master for monitoring, PATROL for Citrix XenServer discovers the inventory (hosts, virtual machines and storage repository) of that resource pool. It also fetches performance data such as memory, network, processor, and disk details for all the hosts and virtual machines that are part of the resource pool.

For a standalone host (that is not part of a resource pool), PATROL for Citrix XenServer discovers all the virtual machines and storage repository associated with the host. It also fetches the performance data such as memory, network, processor and disk details for the standalone host and the associated virtual machines. When you remove a pool master from monitoring, all the hosts under that resource pool are also removed from monitoring.

Using Active Directory integration with Citrix XenServer version 5.5, you can provide access to multiple users to access each resource pool. Because every user account is given the same set of permissions as the local root account, every user can download performance and inventory data for the resource pool. If the user account has been added in the subject list of resource pool, the user can access performance and inventory data of respective resource pool.

If external authentication has not been enabled for a user account, then the local root account is required for connecting and collecting inventory and performance data from XenServers.

The following topics describe the tasks associated with configuring a XenServer:

• Adding a XenServer connection
• Removing a XenServer connection

Adding a XenServer connection

Perform the following steps to add a XenServer host to the Citrix XenServer environment.

1. Right-click the CitrixXenServers node and select KM Commands > Configure Citrix XenServer.
2. In the Configure Citrix XenServer dialog box, provide the following information:
   1. In the PoolMaster/Host text box, enter a name for the pool master or a standalone host (XenServer) that you want to monitor.
   2. In Username, enter user name for the pool master or host. Ensure that this user has at least Read-Only privileges.
   3. In Password, enter password for the user.
   4. In Confirm password, confirm password for the user.
   5. In Port, enter port number for the pool master or host.
3. Click Apply.

Removing a XenServer connection

Perform the following steps to remove a pool master or standalone host from the Citrix XenServer environment.

When you remove a pool master, all the other hosts that are part of the resource pool are also removed from monitoring.

1. Right-click the CitrixXenServers node and select KM Commands > Configure Citrix XenServer. 
2. In the Configure Citrix XenServer dialog box, select the appropriate pool master or host from the Select element to remove list.
3. Select the Remove option.
4. Click Apply.
