Get current server stats (number of players)

[Kallb123]

Is there a way to get stats from a running server (from outside the game)? For example see how many players are connected?

You can check the servers through the Steam server list if you are hosting on a Steam version.
Go to your Steam client.
On the upper left part of the Steam window click "View" > Servers > Game > Select Project Zomboid

I specifically want to get information programmatically in a command line environment. What does the RPC do and how can I interact with it? I can't seem to find any documents about it.

If you have access to the server cmd line then you can use "players" to see which players are currently online.  Typing help on the command line gives you a list of most of the commands.

In the absence of an api, a quick and dirty solution was to count matching lines in the log file. It seems to have worked quite well over the last few days. 

 

echo $(( $(grep ' connected' /path/to/Zomboid/Logs/*user.txt | wc -l) - $(grep 'disconnected' /path/to/Zomboid/Logs/*user.txt | wc -l) )) > /path/to/output.txt

If you use this rcon tool you can issue the players or connections command to the server and parse the output however you'd like.
