NoConsoleSpam
by MichaJDev
NoConsoleSpam filters repeated, low-value messages out of the Fabric server console so that real warnings and errors stand out.
What it does
The mod reads a configurable list of spam patterns and drops matching lines before they reach the log. Built-in patterns cover common noise such as Lithium messages, mismatched block errors, server overloading notices, player movement warnings and class analysis errors. Server owners can add their own patterns, written as regular expressions, through an external JSON configuration file.
Beyond pattern filtering, the mod can silence specific loggers completely and control exception logging. Each exception can be written to its own file inside a Console Errors directory, with default exceptions sorted into subdirectories by the source mod, plugin or class that produced them. That layout makes it simpler to track down which component is behind a given error. The mod runs on Fabric only and needs no client installation, since only the server side uses it. Files are published for 1.20.1, 1.21, 1.21.4, 1.21.5, 1.21.7, 1.21.8, 1.21.9 and 1.21.10, and snapshot builds are also published.
Key features
Built-in spam patterns
Common noisy messages from Lithium, block mismatches, overloading notices and movement warnings are filtered by default.
Custom regular expressions
Additional spam patterns are written as regular expressions and kept in a JSON file that server owners can edit.
Silenced loggers
Specific loggers can be ignored entirely, so none of their output reaches the console or the log.
Per-exception log files
Exceptions are written individually to files in a Console Errors directory, grouped into subdirectories by source mod, plugin or class.
Configurable exception logging
Several options control which exceptions are recorded and how much detail each entry contains.
Compatibility
