Netbox / Napalm Status tab not working

[Wes Hegge]

Hello,

Running Netbox 2.3.2 with Napalm 2.3.0.  I have the Napalm driver set to nxos_ssh for the Cisco Nexus switch.  When I click on the different tabs to get information on the Cisco device this is what happens.

Status - Does NOT Work, fails with the following error: {"detail":"Error connecting to the device at 10.220.164.31: "}

LLDP Neighbors - Works

Configuration - Works

I have raised the timeouts both in Gunicorn and Apache to 60 seconds and restarted Apache and Netbox, but that did not help.  If I use Napalm via Python cli and do get_facts I get information back.  I am assuming the Status tab is trying to execute get_facts.   Is that true?

Any ideas?

Thanks,

Wes Hegge

The status tab calls both get_facts() and get_environment(), the later of which can be hit-or-miss on different platforms. What happens when you call get_environment() on the device via CLI?

Looks like get_environment() is not there.

>>> driver = napalm.get_network_driver('nxos_ssh')
>>> device = driver(hostname='10.220.164.31', username='......', password='......')
>>> device.open()
>>> device.get_environment()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.6/site-packages/napalm/base/base.py", line 405, in get_environment
    raise NotImplementedError
NotImplementedError
>>> device.get_facts()

There is no get_environment in /usr/lib/python3.6/site-packages/napalm/nxos_ssh/nxos_ssh.py file.

Suggestion: Have Netbox check if the get_environment function returns anything, if not don't error out just display the get_facts info.

Thanks,

Wes

Here is what I did to "Fix" this issue.   I plan on implementing the function fully but for now this at least stops the error from appearing.

I created a dummy "get_environment" function based off the IOS driver.  I placed this function just before the "get_facts" definition.

This is on a CentOS 7 server with Python 3.6 and using the nxos_ssh driver.  This should also work for nxos in /usr/lib/python3.6/site-packages/napalm/nxos/nxos.py

vi /usr/lib/python3.6/site-packages/napalm/nxos_ssh/nxos_ssh.py

    def get_environment(self):
        """
        Get environment facts.

        Place holder for this function so netbox will not return an error
        when selecting Status tab on devices
        """
        environment = {}

        environment.setdefault('cpu', {})
        environment.setdefault('memory', {})
        environment.setdefault('temperature', {})
        environment.setdefault('power', {})
        environment['power']['invalid'] = {'status': True, 'output': -1.0, 'capacity': -1.0}
        environment.setdefault('fans', {})
        environment['fans']['invalid'] = {'status': True}

        return environment
