The plugin does not use the template interfacetypemapping.html in release 0.3.7. So it's odd that it is referenced in the error:

django.template.exceptions.TemplateDoesNotExist: netbox_librenms_plugin/interfacetypemapping.html

Did you upgrade from an earlier version of the plugin? It's possible that browser cache causing this. You can try any combination of:

Shift-refresh or Ctrl-F5
Using a different browser
Use “Incognito” or “privacy” mode.

Do you get the same result?

[felix068]

I also find it strange, I did not upgrade from a previous version of the plugin.
And I followed the installation documentation from the README.
NetBox tells me that the installed version of the plugin is netbox_librenms_plugin: 0.3.7, and the error on the web page also shows 0.3.7
And no matter if I use a different browser or privacy mode...

Hi,
I have exactly the same problem on a fresh install of netbox.
NetBox Community v4.2.2
NetBox Librenms Plugin 0.3.7
Debian GNU/Linux 12
Python3.11
librenms 25.1.0-85-gda0bbb817

The problem is present on several different computers and web browsers, so it looks like more server side than client side.
If there is some diagnosis i can run to help you don't hesitate to ask me.

[bonzo81]

Thanks @kurdam.

I've not been able to reproduce this yet.

I did check the 0.3.7 package on PyPi, and it has the correct code, i.e.It points to the correct template interfacetypemapping_list.html

So I don't know why after installing via pip it has a reference to the old template name from 0.3.6

Have you tried any of the following pip arguments when installing:

pip install --upgrade <package>
pip install --force-reinstall <package>
pip install --no-cache-dir <package>

Maybe pip install --vvv <package> might be helpful.

[kurdam]

Thank you for your quick answer.
I did what you recommended me without improvement.
From what i can find there is the file interfacemapping_list.html in my venv

Interface Type Mapping

This section allows you to map LibreNMS interface types to NetBox interface types.
When synchronizing interfaces from LibreNMS, these mappings will be used to ensure
correct interface type assignment in NetBox.

Example: Map LibreNMS type "ethernetCsmacd" to NetBox type "1000base-t"

I uninstalled the module following the documentation from netbox ( https://netboxlabs.com/docs/netbox/en/stable/plugins/removal/ ) and adding the verbose flag

I re-enabled everything following your documentation but still the same error.

Hope this helps.

I also looked for the string interfacetypemapping_list.html in all of the netbox folder and i found this :

root@netbox:/opt/netbox/netbox# grep -rnw '/opt/netbox/' -e 'interfacetypemapping_list.html'
/opt/netbox/venv/lib/python3.11/site-packages/netbox_librenms_plugin-0.3.7.dist-info/RECORD:66:netbox_librenms_plugin/templates/netbox_librenms_plugin/interfacetypemapping_list.html,sha256=wCJ5DYVymKJBR42NUOLGBpQ0c1F3Ztbit7b8LMmvmlw,522
/opt/netbox/venv/lib/python3.11/site-packages/netbox_librenms_plugin/views/mapping_views.py:18: template_name = 'netbox_librenms_plugin/interfacetypemapping_list.html'

[bonzo81]

Thanks for all the info @kurdam

So the template does exist and the view correctly references it. So the install package is correct.

Your screen shot shows another template not found: 'add_device_modal.html'. That would suggest the issue might be related to all templates used in the plugin.

There are other pages that use templates in the plugin such as 'Site & Location Sync' and 'Device Status' pages. Do they display correctly?

Thanks for your assistance.

[kurdam]

You are welcome. Thank you for your help.

They looks like they are working correctly. I'm still adding infos from our infrastructure to netbox.
I don't know what the device status is supposed to show but i have devices declared on both solutions so i don't think this page should be empty.

Edit: regarding the file add_device_modal.html it is not present on my server but is called in netbox_librenms_plugin/views/sync/devices_sync.py line 18

[bonzo81]

There is a new release 0.3.8. It might be worth trying an uninstall of 0.3.7 and an install of latest 0.3.8.

[kurdam]

Hi,
I just updated to the 0.3.8 but unfortunately i still get the same error.
What is weird is that some are detected as you can see in the screenshot, but some other are not and if i try to add them i get the error.

[bonzo81]

Thanks again @kurdam. Disappointing to hear it's still not fixed.

I'm going to spin up a virtual machine to see if I can replicate the issue, because I really don't understand why it's happening.

[bonzo81]

@kurdam

I have found a bug relating to the missing template add_device_modal.html when submitting the form to add the device to LibreNMS. PR #107 should fix that in the next release.

Are you still getting the missing template error when going to the interface mapping page?

[kurdam]

That's good to hear. Thank you again.
I'm still getting the error when i'm adding a device. What is strange is that for some "generic" devices like a PDU it seems to be working but for more complex devices like a router it's crashing.

[kurdam]

I can confirm you as well that i have an error if i try to do an interface mapping ex : ethernetCsmacd -> 1000BASE-T (1GE)

[bonzo81]

Hello again @kurdam Thanks for your patience. I have just released v0.3.9 which should finally resolve the template errors.

[kurdam]

Thank you, it looks more stable indeed. The only thing is that i'm getting an error "Unknown SNMP version". Do you know why ?

Regards.

[bonzo81]

I do know why - looks like I introduced a bug in the last release. It is fixed now in v0.3.10

[kurdam]

I'm getting an error 500 Server Error: Internal Server Error for url: http://librenms.mydomain.lan/api/v0/devices but if i curl this url with my api token i get the list of devices on my librenms.

No logs on librenms and nginx on librenms or netbox and apache on netbox regarding this error.

[bonzo81]

Hi @kurdam

I've changed this to a discussion as the original issues have been closed.

In my experience the 500 Server error is returned from the API because the LIbreNMS server can not ping the device with the given hostname/IP.

If you can add the same device using LibreNMS GUI using the exact details you entered into the 'Add to LIbreNMS' form, let me know, and we can see if there is a bug. Out of interest are your using SNMP v2 or v3?

[kurdam]

Sure, no problem.
Librenms can ping the device in question and is pulling informations from it via SNMP. I added it way before working on netbox.
I'm using SNMPv2 and i intend to switch to v3 later when i have time.

[bonzo81]

Ah, I understand now. The device already exists in LibreNMS but the plugin can't find it. That explains the 500 error when using the 'Add to LibreNMS' form - the device already exists and the API returns 500

For the plugin to match a device in LibreNMS, one of these identifiers must match the LibreNMS hostname used for polling:

• Primary IP
• Valid DNS name (set on the Primary IP)
• Device Name

One of the above values should find a match.

Alternatively, if you have created the librenms_id custom field you can populate that manually with the device ID from LibreNMS.

[kurdam]

It's working perfectly now.
thank you a lot for your help. You have no idea how much time this will save me.

[bonzo81]

Great! Glad it's working for you.

Thanks for reporting issues and giving feedback.
