How to Reduce Console Spam on a Minecraft Server

A cause-by-cause guide to reducing Minecraft server console spam, covering Paper and Spigot logging settings, command blocks, spam exclusions, Multicraft /list output and advanced Log4j2 overrides.

Start by copying one complete repeated line from the console and identifying what generated it. Paper and Spigot expose separate controls for debug logging, player-command logging, command-block feedback and spam exclusions; a Multicraft-generated /list line needs a targeted filter instead. Use a custom Log4j2 configuration only when you control the server’s files and JVM startup flags. Broad suppression can hide warnings or remove an audit trail, so change the narrowest setting that matches the message.

Why identifying the exact line matters

“Console spam” is a symptom, not one setting. The same server can print several unrelated streams: debug events, commands typed by players, feedback from command blocks, a built-in spam filter’s messages, plugin output and commands issued automatically by a hosting panel. Silencing one stream does not silence the others.

Paper’s settings.debug option changes the logging level to ALL. Player commands are controlled separately by commands.log. Vanilla command feedback has its own commands.silent-commandblock-console switch, while known noisy command or chat prefixes can be handled with commands.spam-exclusions. Multicraft’s automatic player-count check is a different case again: it repeatedly runs /list, producing lines that begin with “There are”.

Do not start by deleting log files, editing the server JAR or disabling every warning. First capture the complete line, including its prefix, timestamp, logger name and command text. The wording usually tells you which control is appropriate.

Classify the message before changing a setting

  1. Copy the whole line. Include the part before the message, such as a logger name, plugin name or “issued server command”.
  2. Check when it appears. A line that repeats on a fixed interval may come from a panel or scheduled task; a line that appears only when someone types a command is player-command logging.
  3. Check whether it is actionable. A stack trace, warning or error should not be hidden merely because it is frequent. Debug output can be reduced during normal operation, but restore it while diagnosing a fault.
  4. Match the narrowest remedy. Use a Paper/Spigot option for server-generated categories, a prefix exclusion for one known command, Console Spam Fix for Multicraft’s /list text, and Log4j2 only for a deliberate logger-level or appender change.
  5. Restart after edits. Configuration changes are read when the server starts. If the panel offers separate stop and start controls, perform a complete stop before starting again.
Message pattern or source Likely control Access required Audit and risk
Large volume of diagnostic lines settings.debug: false spigot.yml Reduces debug logging; it does not fix the underlying fault. Keep diagnostic logging available when troubleshooting.
<player> issued server command: ... commands.log spigot.yml Turning it off removes that command audit trail.
Feedback generated by command blocks commands.silent-commandblock-console spigot.yml Suppresses console feedback from vanilla command blocks; command execution itself is not disabled.
One known command or chat prefix Enabled commands.spam-exclusions spigot.yml Narrow when the prefix is exact; broad prefixes can hide useful evidence.
Repeated Multicraft player-count output beginning “There are” Console Spam Fix plugins folder and generated plugin configuration Targets the known console text on Bukkit-based servers; it is not a general logger replacement.
Several logger categories or appenders Custom Log4j2 configuration Configuration file plus JVM startup flag Potentially broad and version-sensitive; the exact effect depends on the configured console and file appenders.

Reduce Paper and Spigot output with spigot.yml

Disable debug logging during normal operation

Paper’s current spigot.yml reference describes settings.debug: false as: “Enables debug logging, by setting the log level to ALL.” Keep this value false unless you are actively diagnosing a problem.

settings:
  debug: false

Open the spigot.yml belonging to the server instance you actually start, change only the value, save it and restart. This is a logging-volume control. It does not repair a plugin exception, a configuration error or another fault that caused the messages. If you need detailed evidence for troubleshooting, set it back while reproducing the problem, then return it to false after collecting the relevant lines.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Decide whether player-command logging is needed

Paper documents commands.log: true as logging commands executed by players in chat or on signs, with lines in the form <playername> issued server command: <command>. Set it to false only when you accept losing that audit trail.

commands:
  log: false

This setting is appropriate when the repeated text clearly identifies player-issued commands and you do not require a record of who ran them. It is not a substitute for fixing a command that is failing, and it does not necessarily affect unrelated plugin messages that happen to contain command text.

Silence command-block feedback without disabling command blocks

The commands.silent-commandblock-console value controls whether vanilla command feedback is logged to the console. The documented default is false. Change it to true when command blocks are the source of repetitive feedback and you still want the blocks to execute.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Use spam exclusions for a specific prefix

Paper’s commands.spam-exclusions list accepts command or chat prefixes for the built-in spam filter. The exclusions are applied only when commands.enable-spam-exclusions is enabled. Commands must include a leading slash to be treated as commands.

commands:
  enable-spam-exclusions: true
  spam-exclusions:
    - "/examplecommand"

Replace the example with the exact prefix you understand. A prefix should be as specific as practical: excluding one known noisy command is safer than excluding a short fragment shared by many commands. Add the entry, save the file and restart. If the line still appears, compare the printed text with the configured prefix, including the slash and any namespace or argument that the server emits.

Do not use exclusions to conceal warnings, errors or unknown plugin output. The point is to remove a known, repetitive category while preserving messages that may explain a crash, permission problem or broken automation.

Fix repeated Multicraft /list messages

Multicraft can run /list automatically to track the player count. The resulting output is commonly repeated in the console and begins with “There are”. On a Bukkit-based server—such as Spigot, Paper, Purpur or another Bukkit derivative—the documented targeted remedy is the Console Spam Fix plugin.

Install and generate the configuration

  1. Stop the server completely.
  2. Upload the Console Spam Fix plugin JAR into the server’s plugins directory.
  3. Start the server once. This first run creates the plugin’s configuration.
  4. Stop the server again before editing the generated file.
  5. Open plugins/ConsoleSpamFix/Config.yml.
  6. Under Messages-To-Hide-Filter:, add the quoted filter entry:
Messages-To-Hide-Filter:
  - 'There are'
  1. Save the file and restart the server.

The filter is intended for the /list output that starts with “There are”. Keep the phrase narrow and confirm that it matches the line you copied. Do not add generic words such as “error”, “warning” or “failed”; doing so could hide unrelated problems. If the server is not Bukkit-based, this plugin procedure does not apply, so use the server’s own logging controls or the panel’s supported configuration instead.

What this filter does—and does not do

Console Spam Fix is a text filter for the known Multicraft message. The documented behavior is that the matching /list output is filtered from the console. The procedure does not establish that every retained log file, web panel transcript or external log collector will be altered; check those destinations separately if preserving or reducing them matters.

Use Log4j2 only when you control startup and files

A custom Log4j2 configuration is the advanced option for administrators who need to change logger levels, filters or appenders beyond the Paper/Spigot settings. It is not the first choice for one repeated line, because a broad logger rule can remove useful output and the configuration is tied to the server build.

Place the configuration and pass the JVM property

Spigot’s logging guide describes placing a file named log4j2.xml beside spigot.jar and adding the system property before the -jar argument:

java -Dlog4j.configurationFile=log4j2.xml -jar spigot.jar

If the file is stored elsewhere, the documented pattern can use a relative path such as:

The property must be part of the JVM startup command, not typed as a Minecraft command after the server has started. Shared hosting panels may not expose startup flags, in which case this method may be unavailable. Do not assume that uploading the XML file alone changes anything.

Understand the maintenance cost

Editing the server JAR is possible, but it must be repeated after server updates and can make support and rollback harder. A separate configuration file selected with the JVM property is easier to replace, but it still needs review whenever the server software changes.

Paper’s shipped log4j2.xml is a version-sensitive baseline. The documented file uses an info-level root logger, an asynchronous appender, a rolling logs/latest.log file and a NETWORK_PACKETS marker filter that denies those events. Compare your custom file with the configuration shipped by the exact Paper build you run rather than copying an older file unchanged. A setting that is valid for one build may omit an appender or logger expected by another.

Choose filters conservatively

Log4j2 rules can affect whichever appenders you configure, including console output and retained log files. Make one narrow change at a time, keep the original XML as a rollback copy and restart to test. If the server fails to start after adding the JVM property, remove the property or restore the previous command and configuration before investigating the XML. A startup failure is more serious than noisy output.

Console suppression versus retained logs

“Not visible in the console” and “not recorded anywhere” are different outcomes. A panel may display the live console while the server also writes logs/latest.log or rotates older files. Paper/Spigot category settings change what the server emits through its logging system; the exact destinations depend on the server’s logger configuration. The Multicraft plugin procedure specifically documents filtering the console text, so do not presume that it rewrites every external copy. A custom Log4j2 file can deliberately change console and file appenders, which is why it deserves a narrower scope and a rollback plan.

The monitor stand offers +85°/-50° tilt, ±90° swivel and 360° rotation. Raise your monitor up to 15.75″ to support a healthy sitting posture. Whether you’re working from home, gaming through the night, or switching between video calls and documents, getting the screens to your natural line of sight helps relieve neck, shoulder and back strain so you can stay focused longer with less fatigue.
  • Keep Your Desk Organized: By lifting both screens off the desktop, this dual monitor stand opens up valuable space for your keyboard, notebook, docking station or a simple, clutter-free work area. Built-in cable management guides wires along the arms, keeping cords out of sight and out of the way. Enjoy a tidy, modern workstation that looks as good as it feels to use.

Before disabling a category, decide whether you need it for moderation, command auditing, incident analysis or plugin support. In particular, turning off commands.log removes the documented record of player-issued commands. If you only want a quieter live panel while retaining evidence, prefer a destination-specific logger or panel display control when your hosting environment provides one; the settings described above do not promise that behavior by themselves.

Troubleshooting when the spam continues

The setting appears to have no effect

  • Confirm that you edited the configuration for the server instance being launched, not a backup or a different world directory.
  • Check YAML spelling and indentation. The keys are settings.debug, commands.log, commands.silent-commandblock-console, commands.enable-spam-exclusions and commands.spam-exclusions.
  • Perform a full restart. A live reload is not a reliable substitute for restarting the logging subsystem.
  • Copy a fresh line after the restart. If its wording or prefix differs, it may come from another source.

The command-block line remains

Verify that the message is command-block feedback rather than a plugin’s own message. The silent-command-block option governs vanilla command feedback; a plugin can log separately. If the line names a plugin or includes a stack trace, investigate that component instead of broadening the suppression.

The /list filter does not work

  • Confirm the server is Bukkit-based and that the plugin loaded without an error.
  • Check that the generated path is exactly plugins/ConsoleSpamFix/Config.yml.
  • Place - 'There are' under Messages-To-Hide-Filter:, preserving YAML indentation and quotation marks.
  • Stop and start after saving. Then compare the remaining line character-for-character; a different player-count message may not match this filter.

The Log4j2 override is ignored or breaks startup

Make sure -Dlog4j.configurationFile=... appears before -jar in the startup command and that the path is readable from the server’s working directory. If a shared panel does not allow custom JVM arguments, use the supported Paper/Spigot settings or a panel-level filter instead. If startup fails, remove the override and return to the original shipped configuration before making further changes.

A practical decision sequence

  1. One repeated “There are” line from Multicraft: use the Bukkit plugin filter and keep the phrase exact.
  2. Diagnostic volume while the server is healthy: leave settings.debug at false; enable it temporarily only to investigate.
  3. Player command audit lines: decide whether the audit trail is required, then change commands.log only if its loss is acceptable.
  4. Command-block feedback: set silent-commandblock-console to true when you want execution to continue without vanilla console feedback.
  5. One known noisy command: enable spam exclusions and add the narrow, slash-prefixed command or chat prefix.
  6. Complex logger or appender requirements: use Log4j2 only with file access, a controllable startup command and a version-matched baseline.

This sequence keeps the remedy proportional to the source. It also leaves a clear path back: restore the original YAML value, remove the filter entry or remove the JVM property, then restart and verify the output.
