DeltaLogger
A block, container and entity logging tool for the fabric mod loader
About this Mod
Block and chest/container inventory tracking tool for fabric that can be configured to use MySQL or SQLite.
Setup
DeltaLogger supports two types of database: MySQL and SQLite
Place the mod jar in the mods folder of your server directory and launch your fabric server once to make it generate a config/deltalogger.properties. Or make a file called deltalogger.properties in the config folder of your server directory. Put the following as the file content:
# DeltaLogger configuration
# Whether you want to use an SQLite database. Put false for MySQL.
use_sqlite=true
##! MYSQL ONLY BELOW. If you are using SQLite these are safe to ignore. !##
# Name of the MySQL database to use. If you do not have one, then do
# "CREATE DATABASE yourdbname" from a MySQL client first.
database=
# MySQL port
port=
# MySQL host/url
host=
# MySQL username
username=
# MySQL password
password=
# MySQL SSL configuration. You can leave this as false but the database
# connection will not be encrypted. If you are using MySQL across the open internet
# then you should strongly consider properly enabling SSL
useSSL=false
requireSSL=false
By default, SQLite is enabled. This means that your logs will be saved to a database found in world/deltalogger.sqlite. If you want to use MySQL, fill out the additional properties with the relevant information to access your database and set use_sqlite to false.
This mod also requires the fabric api mod, which you can find here.

DeltaLogger server crashes on startup – what to do?

Server lagging with DeltaLogger – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if DeltaLogger consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
