I own one and it was a mistake to buy it. We thought the idea of it being a casting spot would be useful but having to approve the incoming stream every time was a deal breaker. Plus it totally sucked for multi user use. Why do I need to tap my profile to quick unlock with my fingerprint? In my opinion this thing was a total flop and I should have sought out a refund from Google given how useless this thing is. All it does now is sit on my counter and cycle my wife’s cell phone pics of our kids.
It’s an old school log aggragating service that used to be how most *nix distros collected logs in years past. As I understand it was generally replaced by systemd’s journald service. The only times I encounter it in the wild is on legacy systems that couldn’t or refused to adapt and chances are they’re paying a lot cuz it’ll be a painful support experience. Oh and for some it can be a useful way to sync logs up to monitoring services like Splunk but it’s effectiveness is debatable.
