Filter or highlight devices in rack elevation based on device attributes

[ryanmerolle]

Environment

• Python version: 2.6.9
• NetBox version: 2.7.11

Proposed Functionality

Allow a device filter or highlight (ie fade devices not matching criteria) option in rack elevations based on device attributes like tag, platform, device type, manufacturer.

Use Case

This would be useful to view your racks and provide easier visibility of where devices of a similar attribute are physically racked.

Database Changes

N/A more of a front end tweak.

External Dependencies

Not a major request, and I understand if you think its not worth the effort. I just had a user who wanted to see where exactly all devices of a particular tag were racked. Currently, there is no easy way to view this all in the rack elevations view.

I don't think we'd be able to use the filtersets for this, so it would need some new mechanism for indicating which devices to highlight. It's probably too much to ask for in the API natively at this point, and better suited to implementation directly within the UI. (For example, to highlight all device elements with foo in their data-tags property.)

I could see a partial implementation where we pass device IDs in the form ?render=svg&highlight=123&highlight=456. This could be useful for providing a "view in rack" link for individual devices (or in the case of virtual chassis, multiple devices).

That does not sound like a bad approach at all.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. NetBox is governed by a small group of core maintainers which means not all opened issues may receive direct feedback. Please see our contributing guide.

Please consider including device status when implementing this feature... how great would it be to generate a rack elevation that highlights all devices with the planned status or the decommissioning status?

[ekrichbaum]

To avoid messing with the display of the rack elements themselves, set the color of the RU number background. I was originally thinking based on the role color and then having a role for deprecated, but assigning colors to the states of the device would work as well.

Per #9035 we should also support highlighting rack reservations.

It would be nice if you navigate to the rack page from a device page via the U position link for it to automatically highlight the device on the rack view.
