Modules generated by the plugin
An agent will be created for each machine in our openstack installation., with its metrics (to load the data of another instance, we will have to execute the plugin again, changing the id of the instance. Apart from this, an agent will be created for each hypervisor used in our installation.
Instance agent modules
| Nombre | Descripción |
| memory | memory used by the machine |
| memory-actual | memory actual used by the machine |
| memory-rss | Resident Set Size and is used to show how much memory is allocated |
| vda_errors | diagnostics for a libvirt based instance, vda receibed errors |
| vda_read | diagnostics for a libvirt based instance, vda dates read |
| vda_read_req | diagnostics for a libvirt based instance, vda dates requests read |

Modules generated in the hypervisor agents:
| Nombre | Descripción |
| free_disk_gb | avalaible disk space |
| free_ram_mb | available ram |
| disk_available_least | this value is dependent on over committed value of disk, disk_available_least = disk_free_gb - disk_over_committed |
| local_gb | the total available disk for the node's virtual machine, local_gb = local_gb_used + free_disk_gb |
| local_gb_used | the sum of the node's virtual machine disk |
| memory_mb | the total ram of the node, memory_mb_used + free_ram_mb |
| memory_mb_used | the sum of the rams of the node's virtual machine |
| vcpus | node physical cpu total threads |
| vcpus_used | the sum of the vcpus of the node virtual machine |
| current_workload | hypervisor current workload |
| host_ip | hypervisor host ip |
| hypervisor_type | hypervisor type |
| hypervisor_version | hypervisor version |
| running_vms | number of virtual machines running |
