Supported versions of Citrix XenServer: XenServer 5.6 and 6.2.
Follow the steps given below to create a new Citrix XenServer monitor:
Do not discover: Applications Manager will not discover VMs. You can monitor only XenServer Host and its performance.
Discover VM but do not monitor metrics (Will not count for licensing): Applications Manager will discover VMs and monitor its availability. You can also monitor XenServer Host and its performance.
Discover and monitor VM metrics:Applications Manager will discover VMs, as well as monitor the availability and performance for both XenServer Host and VMs.
Applications Manager automatically discovers the slave XenServer Hosts under the Resource Pool when adding the Master XenServer Host. Once the Master XenServer host is added, the resource pool will be discovered and added as a monitor group. The user must provide the credentials for the slave XenServer Host and manage the XenServer Host to collect the performance metrics. Adding a Slave XenServer Host is equivalent to a standalone XenServer Host and Applications Manager will not determine the master and other slave XenServer Hosts. Read more about XenServer monitor and metrics monitored.
Applications Manager provides monitoring support and virtual machine management of your Citrix XenServer infrastructure with a comprehensive view into individual components. You can monitor XenServer host metrics, virtual machines metrics for your XenServer 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 XenServer host and VM level. Once the XenServer 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.
The Availability tab shows the Availability history of XenServer for the past 24 hours or 30 days. The Performance tab shows some key performance indicators of theXenServer 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.
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 XenServer Host is added.
Once the Master XenServer host is added, the Resource Pool will be discovered and added as a monitor group. All the slave XenServer hosts under the resource rool will be discovered automatically and all the XenServer Hosts (both Master & Slaves) will be mapped to the Resource Pool.
The discovered slave XenServer hosts are added in 'UnManaged' state. To associate/dissociate any monitors to this Resource Pool, the user must provide the credentials for the Slave XenServer Host and change it to managed state. After providing the credentials, Applications Manager discovers the virtual machines under the slave XenServer Host and collects performance metrics.
The Resource Pool will have the separate details view which has the following list of information:
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.
