This is an Open Source ZenPack developed by Zenoss, Inc. Enterprise support for this ZenPack is available to commercial customers with an active subscription.
This ZenPack provides support for monitoring XenServer. Monitoring is performed using XenAPI.
The features added by this ZenPack can be summarized as follows. They are each detailed further below.
The following components will be automatically discovered through the XenServer host, username and password you provide. The properties and relationships will be continually maintained by way consuming events from the host. By default model changes will be polled every 60 seconds. This can be configured with the zXenServerModelInterval configuration property.
The following metrics will be collected every 5 minutes by default. This can be configured with the zXenServerPerfInterval configuration property. Any metric that is available either via a XenAPI get_record or rrd_updates call can be collected by adding a new XenServer XenAPI or XenServer RRD datasource to the appropriate monitoring template. Note that as of XenServer 6.2, all available metrics are collected by default.
Zenoss watches for XenAPI messages and creates Zenoss events when they occur. XenAPI messages are the system alerts you see in XenCenter. By default, Zenoss will poll for new messages every 60 seconds. This can be configured with the zXenServerEventsInterval configuration property.
The created Zenoss events will have the following fields set.
When combined with the Zenoss Service Dynamics product, this ZenPack adds built-in service impact and root cause analysis capabilities for services running on XenServer. The service impact relationships shown in the diagram and described below are automatically added. These will be included in any services that contain one or more of the explicitly mentioned components.
Use the following steps to start monitoring XenServer using the Zenoss web interface.
Alternatively you can use zenbatchload to add XenServer endpoints from the command line. To do this, you must create a file with contents similar to the following. Replace all values in angle brackets with your values minus the brackets. Multiple endpoints can be added under the same /Devices/XenServer section.
/Devices/XenServer loader='XenServer', loader_arg_keys=['name', 'address', 'username', 'password', 'collector']
my-xenserver-pool name='my-xenserver-pool', address='<address>', username='<username>', password='<password>', collector='localhost'
You can then load the endpoint(s) with the following command.
Installing this ZenPack will add the following items to your Zenoss system.
This ZenPack provides additional support for Zenoss Analytics. Perform the following steps to install extra reporting resources into Zenoss Analytics after installing the ZenPack.
You can now navigate back to the XenServer ZenPack folder in the repository to see the following resources added by the bundle.
Domains can be used to create ad hoc views using the following steps.
$ sudo su - zenoss
$ zenpack --install ZenPacks.zenoss.XenServer-*.egg
$ zenoss restart
In order to do a development mode installation you will want to clone the existing git repository, and then use the --link flag with the zenpack command:
$ git clone https://github.com/zenoss/ZenPacks.zenoss.XenServer.git
$ zenpack --link --install ZenPacks.zenoss.XenServer
