Create a page to show centinel's deployed client base about centinel

• Is this visible to contributors or everyone?

There can be different levels of visibility in terms of details and aggregation. We can show everyone the number of clients in different countries, but show more details to administrators and registered users.

• How good is good enough for geographic aggregation?

When displaying the clients to the public, country-level should be good enough. We can store finer-grain location and IP address information on the server (e.g. city-level, /16 and/or AS number) that are only visible to users with higher privilege or trust level. @phillipa and I discussed this a bit with CitLab people, but didn't get to hammer out details.

• Are we giving out too much info if we say whether the node is a VPN or not? This is important from a network measurement perspective, but it may identify users of the tool.

When displaying to the public, whether or not a node is connected to VPN is irrelevant and I think shouldn't be displayed for the reason you mentioned. But we might want to show this to users with higher trust level (e.g. admins).

This seems non-trivial, so I'm moving it out of the alpha release.

Sure but I assume the server includes some logging of who contacts it/when for our purposes though so we can see whether RPi deployments in the near term have successfully started up/phoned home?

The page exists and looks decent.

I just wanted to flag that when folks have more time it would be nice to have some notion of timing out nodes that have not signed in for some predefined time threshold, e.g., 7 days. For our debugging we may want to maintain an internal page/list of clients that haven't phoned home in 3 or so days in case they are Pis/things we should investigate/debug.

We should also think about how to include the VPN nodes in this list (e.g., cycle through them each day). Also maybe chance "VPN" column to "type" (ideally our DB will log if a client is VPN, RPi, Mobile, or other install type).

This has been done.
