# Agents generated by the plugin The plugin generates three types of agents: ● virtual machine (VM) ● storage disk (SR) ● XenServer (Host) **Storage Repository (SR) type agents** For each SR an agent will be generated, which will have a name of the type: XenSR\_<name\_of\_SR> **SR Agent Modules** For each agent of this type the following modules will be generated:

Name	Description	Data type	Unity
physical\_size	Physical space	generic\_data	GB
physical\_utilisation	Physical use	generic\_data	GB
free space	Free space	generic\_data	GB
used percent	Percentage of SR used	generic\_data	%

**Virtual Machine (VM) type agents** Each agent will have the IP of the virtual machine and its system operating (as long as you have XenServer Tools installed **VM Agent Modules** For each agent of this type the following modules will be generated:

Module name	Description	Data type	Unity
Status	Returns whether a VM is running or not	generic\_proc	-
Status description	state name	generic\_data\_string	-
Memory used	RAM percentage used	generic\_data	%
cpuX	CPU load percentage	generic\_data	%
Xenxerver Tools	Check if the VM has been installed and update XenServer tools	generic\_proc	-
VDI\_<nombre vdi>	VDI size	generic\_data	GB
Vbd\_XX\_write	Write speed in bytes per second	generic\_data	Bytes/sec
Vbd\_XX\_read	Reading speed in bytes per second	generic\_data	Bytes/sec

**XenServer-type agents** An agent will be generated for each host or server, which will have a name of the type: <XenServer\_name> Each agent will recognize your IP. **XenServer Agent Modules** For each agent of this type the following modules will be generated:

Module name	description	data type	unity
VMs running	Number of VMs running	generic\_data	-
VMs installed	Number of VMs installed	generic\_data	-
Memory used	RAM percentage used	generic\_data	%
Load CPU avg	Average load percentage CPU	generic\_data	%
