Netbox reports - Check IOS running on devices

[Donnchadh Woods]

HI there,

Just wondering if anyone knows if this is possible with Netbox...

Netbox is running and can query device status via NAPALM.

Is it possible to run a report that checks the IOS on a group of devices and spits it out into a report ? 

Cheers,

Donnchadh.

We ended up running a python script that uses Napalm to grab the current IOS version of all the IOS devices in Netbox and saving it to a custom field. You can run reports based on that.

import pynetbox

from napalm import get_network_driver

driver = get_network_driver('ios')

nb = pynetbox.api(url="http://netbox.domain", token="api-token")

devices = nb.dcim.devices.filter(platform="cisco", status=1, has_primary_ip="True")

for i in devices:

    device = driver(i.name, 'username', 'password')

    try:

        device.open()

        facts = device.get_facts()

        device.close()

        rtr = nb.dcim.devices.get(name=i.name)

        rtr.custom_fields['version'] = facts['os_version']

        rtr.save()

    except:

        print("Error updating ",i.name," version")

        print("")

Thanks Adrian..

Just got this working... Its brilliant.. 

Did you do anything similar to grab subnets from devices and add to Netbox by any chance ? 

New to python so I'm pretty limited at the mo..
