Unable to select host if the hostname in UI if is duplicate

[jemos]

Fleet version: 3.6.0
Operating system: macOS 10.15.7
Web browser: Firefox 86.0.1

---

🧑‍💻  Expected behavior

Trying to select an host from the list of Fleet hosts for making a query in the New Query page. If I have two hosts with the same name it doesn't let me select one of them. I suspect this could be a problem in the frontend UI.

💥  Actual behavior

When I put the mouse over the second item with duplicate name it will highlight the first instead.

More info

Probably the hostname is being used to identify the item to be selected instead of some unique ID.

@jemos are you observing this behavior in the target selector on the "New Query" page?

Do you mind sharing a screenshot of this behavior?

[jemos]

Yes, sure:

Having the mouse over the second item, it will highlight the first.

I noticed there were some recent updates regarding hostname identification, I tried to use different values in the past (few months ago) in osquery but didn't change the Fleet host identification column (which is what I wanted at that time.) If it's something necessary to also avoid this bad behavior, I could try.

Probably the hostname is being used to identify the item to be selected instead of some unique ID.

This is likely the issue which would make this a frontend bug.

[noahtalerman]

The updates to hostname identification included in 3.9.0 are improvements for managing duplicate enrollment scenarios. Utilizing these improvements may be helpful if duplicate enrollment is contributing to the issue here.

Do you intentionally have 2 hosts with the same hostname? Or, instead, is this the same host that happened to enroll to Fleet twice?

[jemos]

It was not intentional in this case but it can happen.

Anyway I just upgraded to the latest version of Fleet and now there is a search box that allows us to do queries on hosts from search results. This was not available in the version I was using as far as I know and I had to rely on that target selection control. For my use case it solves the problem at least! :)

Cheers for successfully upgrading!

I'm going to keep this issue open to track the frontend bug:

• In the target dropdown selector in which there are two hosts with the same hostname, hovering over the second host will produce the hover state over the first.
