Showing Last Check-in Time

[FlareImp]

Is there a way to show when a client last communicated (checked in) with the fog server? I’d like to compile a list of all my clients showing their check-in times and see if any clients are no longer communicating.

@FlareImp While I don’t have a simple answer to approach, we do track the last time the security token was updated. Which I believe is set at 15-30 minute increments.

You could write a hook to expose that on the UI. Right now there isn’t a component that updates the last checkin time in the database though, so not quite sure if this will fit the needs.

I will try to mock up what a sample of the hook might look like that you could at least glean that last status time.

@Tom-Elliott This is completely untested and I’m sorry for that, but should give a potential way forward:

@Tom-Elliott Awesome, thank you very much! I’ll start playing around with this.

[FlareImp]

I gave your script a try and it crashes with web UI when set from active=false to active=true.

[Tom Elliott]

@FlareImp What’s the error log show?

It’s likely a call that I overlooked.

I just gave a quick baseline, not a tested instance as it’s been a while since I built a hook, and I don’t have my normal environment since years now.

[FlareImp]

@Tom-Elliott dumb question but where would I find the log file for hooks?

[Tom Elliott]

@FlareImp It wouldn’t be the hook specifically, but the general php/http logs.
