Extract useful information from an RVTools ESX inventory file

Project description

Extract useful information from an RVTools ESX inventory file.

Purpose of that module

Did you have ever ask to an VMWare administrator to have an access to his vCenter to run some scripts by API ? No ? Me yes and a least that can i say : it’s not easy ! ;-)

More seriously, it very often hard to get access to this kind of VM because it’s very sensitive part of the infrastructure and because the guys generally are not in the same team as you and they not trust you (neither in your scripts !), so it does not help. But, to be honest, you’ll probably do the same thing if the situation was reversed.

But sometimes, they can send you an RVTools extraction (so an Excel file) from that vCenter and you want to use it in a Python script. You’ll prefer have to access directly to the vCenter by API call to get fresh data but it’s better than nothing…

That’s why i coded this library : to help to use this kind of inputs to extract some useful information from it.

How to install it

You can install pyRvtools by using pip :

pip install pyrvtools

How to use it

You can search for 5 kind of major objects with that module: - DataCenter - Clusters - Hosts - DataStores - VirtualMachine

Each of them have a specific number of properties. You can iterate on all object or focus only on one of them giving his name.

Here is some examples (please refer to the list of properties below if you’re looking for a metric):

import os
from pyrvtools import PyRvtools

PATH = os.sep.join(['your_path', 'your_file.xls'])
rvtools = PyRvtools(PATH)

# For all the dataCenters
for dc in rvtools.get_datacenters():
    print('DC: %s Clusters: %s' % (dc, dc.clusters))

# Only for a specific DataCenter
one_dc = rvtools.get_datacenter_by_name('MY_DC')
print('DC: %s Clusters: %s' % (one_dc, one_dc.clusters))

# For all the Cluster
for cluster in rvtools.get_clusters():
    print('Cluster: %s Hosts: %s' % (cluster, cluster.hosts))

# Only for a specific Cluster
one_cluster = rvtools.get_clusters_by_name('MY_CLUSTER')
print('Cluster: %s Hosts: %s' % (one_cluster, one_cluster.hosts))

# For all the DataStores
for ds in rvtools.get_datastores():
    print('DS: %s Hosts: %s' % (ds, ds.hosts))

# Only for a specific DataStore
one_ds = rvtools.get_datastore_by_name('MY_DS')
print('DS: %s Hosts: %s' % (one_ds, one_ds.hosts))

# For all the hosts
for esx in rvtools.get_hosts():
    print('ESX: %s VM:%s' % (esx, esx.vm))

# Only for a specific host
one_esx = rvtools.get_host_by_name('MY_ESX_NAME')
print('ESX: %s VM:%s' % (one_esx, one_esx.vm))

# For all the VirtualMachine
for vm in rvtools.get_vm():
    print('VM: %s DataStore:%s' % (vm, vm.datastore))

# Only for a specific VM
one_vm = rvtools.get_vm_by_name('MY_VM')
print('VM: %s DataStore:%s' % (one_vm, one_vm.datastore))
