Pliki Logów
Logfiles are an essential part when it comes to debugging your server and figuring what went wrong. This page contains logfiles from SpongeForge and SpongeVanilla servers including short descriptions.
Provided Logfiles
Configure Logging
Sometimes plugins log messages that the server owner does not need, or the sheer number of messages hide some more important information. In other cases, plugins or the server will log debug messages that normally don’t appear in any logs. This section explains how to configure the logging. It is also possible to configure the logging in a way that splits the logs in two or more separate files. One could be optimized for the moderators that pay attention to their users» activity/behavior and other logs could be used to monitor plugins that are important to the admins.
Informacja
If you think that a plugin logs too many/few messages or on wrong log levels, please report it to its author.
The simplest way to configure the logging is modifying the log4j2.xml
configuration file that will be used by
Minecraft/Forge itself. You can find and extract it from the root of the forge-...-universal.jar
and
minecraft_server.jar
. Do NOT edit the file inside the jar.
You can tell log4j2 to use the new config file by adding a start parameter to your server launch script.
java -Dlog4j.configurationFile=log4j2_server.xml -jar server.jar
The default configuration looks similar to the following example.
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" packages="com.mojang.util,net.minecraftforge.server.console.log4j">
<Appenders>
<TerminalConsole name="Console">
<PatternLayout pattern="[%d{HH:mm:ss}] [%t/%level] [%logger]: %msg%n"/>
</TerminalConsole>
<RollingRandomAccessFile name="DebugFile" fileName="logs/debug.log" filePattern="logs/debug-%i.log.gz">
<PatternLayout pattern="[%d{HH:mm:ss}] [%t/%level] [%logger]: %msg%n"/>
<Policies>
<OnStartupTriggeringPolicy/>
<SizeBasedTriggeringPolicy size="200MB"/>
</Policies>
<DefaultRolloverStrategy max="5" fileIndex="min"/>
</RollingRandomAccessFile>
</Appenders>
<Loggers>
<Logger level="info" name="org.spongepowered"/>
<Logger level="info" name="com.example.mod"/>
<Root level="all">
<AppenderRef ref="Console" level="info"/>
<AppenderRef ref="DebugFile"/>
</Root>
</Loggers>
</Configuration>
Informacja
This example lacks some comments that are present in the original, make sure you read them to understand why they are there.
The Appenders
section defines the output channels for the log messages. This could be a file, the console, or even
a central log collection and analysis server. Read more about configuring appenders
here.
The Loggers
section defines filters for loggers and to which targets the messages should be forwarded to. This is
usually the section you must edit if you want to mute a specific plugin in the logs. Let’s look into this
a bit more:
<Logger level="info" name="com.example.mod"/>
This will limit the logs of com.example.mod
to info
and higher messages. Beware, this affects all output
channels and also any logger that is created for a sub-package of the given path. Read more about filters
here.
<Root level="all">
<AppenderRef ref="Console" level="info"/>
<AppenderRef ref="DebugFile"/>
</Root>
This section configures two output channels. First, the appender called Console
with a log level filter of info
and higher, and last, the appender called DebugFile
. It is recommended to keep at least one logger to a persistent
target such as a file for later error search.
Informacja
If you are wondering why your new plugin’s log messages don’t seem to show up: The Console’s log level is configured to be at least info by default which hides your debug messages.
If you don’t want to reconfigure the entire logging, but want to hide a certain plugin from the logs you can also use composite logging options. This can be achieved by referencing both the original logging config and your specialized config that only contains the changed logging options. The following example shows this:
java -Dlog4j.configurationFile=log4j2_server.xml,log4j2_custom.xml -jar server.jar
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Loggers>
<Logger name="com.example.logspammer" level="off"/>
</Loggers>
</Configuration>
In this example all logs from the com.example.logspammer
package won’t be shown or saved. For debugging purposes, it
might be useful to include your plugin’s log messages in the console so you don’t have to tail
the debug log. This
can be achieved using the following example:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Loggers>
<Logger name="com.example.newplugin" level="all" additivity="false">
<AppenderRef ref="Console"/>
[...]
</Logger>
</Loggers>
</Configuration>
Wskazówka
Logging affects performance. If you log too much you might lose a small amount of tps. Also remember that it will become harder to reproduce errors if there are no/incomplete logs available.
SpongeForge logfiles
SpongeForge writes several logfiles to the /logs
folder located inside your server’s directory.
As of Forge 1.12.2 - 14.23.4.2705 these are:
debug.log
latest.log
debug.log

Only a few example lines are shown here. To read the full example log, follow this link:

If you’re unsure on how to read a common crashlog, you’ll find help here, but first we need a crashlog. For this short
introduction we will just use an example crash from the Debugowanie page:
Example crashlog of an outdated SpongeForge build
.
WARNING: coremods are present:
SpongeCoremod (sponge-1.8-1499-2.1DEV-575.jar)
Contact their authors BEFORE contacting forge
The first thing you’ll notice is a Warning
that coremods are present. Nothing to worry about here, that’s not an
error, just a warning to contact Sponge support, not Forge.
java.lang.NoClassDefFoundError: org/spongepowered/api/event/game/state/GameStartingServerEvent
A few lines below the actual error is found. In this case it’s a NoClassDefFoundError
If you’re unsure what that
means, head over to our Debugowanie page. If it’s a common error, it will be listed there. If it isn’t, you can
always ask on the forums for help! Make sure you provide the full crashlog.

Please note that the other three installed mods (mcp, FML, Forge) are required on every Forge server and necessary to run properly.
Teraz poniższe założenia mogą zostać przyjęte:
może wtyczka wyłączyła serwer
SpongeForge nie pasuje do wersji Forge: 1499 wymagane, 1521 zainstalowane
