How to monitor minetest server?

[vitaminx]

Hi everyone, how you are monitoring your servers? I saw some nice graphs around with the number of connected players and some other general stuff like CPU usage and such.
How do you pull the numbers out of the minetest server? Do you write a script that connects to the API and returns the values or are there already premade scripts or mods doing that?

The question is not about which monitoring tool to use (cactii, munin, nagios, zabbix, etc.) because I already have my favorite system (zabbix), but rather about how to pull all the numbers from the server.

Thanks!

You can have a Lua mod that writes e.g. the number of players into a file every 30 seconds.

VanessaE has some nice shell scripts that parse the log files to get all kinds of info.

some example which is running fine on our private server.. rest info about CPU usage, RAM usage etc. is gathered by standard linux tools

Awesome! That helped a lot and together with some logfile grep magic this is what I came up with.
