在解决Minecraft运行故障时，除崩溃报告外，运行日志是另一个分析Minecraft故障原因的有效途径。通过运行日志，我们可以得出故障发生的时机从而初步判断可能的故障原因。有时，日志中的报错能直接告诉我们故障的准确原因。
通常，日志文件被储存在游戏目录下的logs文件夹中，最近一次运行日志为latest.log，更早的日志可在名称类似于2022-12-17-7.log.gz的压缩包中找到。
如果游戏在本体启动前就发生了致命错误，那么此次运行很可能不会产生任何日志文件，而且有些严重的报错并不会出现在日志中文件中，但这两种情况下一些关键运行输出仍可在控制台输出和启动器中显示的日志中被找到。此时，我们应格外注意日志文件夹中的日志中显示的崩溃时机和修改时间与当前的运行是否匹配，因为不匹配的运行日志会对故障检修造成极大的误导。
随便选其日志中的一行，如下
[14:25:44] [Render thread/INFO]: Backend library: LWJGL version 3.2.2 build 10
可以将这样一行分为以下几个部分
[时间] [线程/日志类型]: 正文
其中，常见的线程有以下几种
常见的日志类型有以下几种：
一般而言，日志中很大的篇幅是可以忽略的，我们只需要关注少量的重点内容：
如果添加了Mod，还应尤其关注如下内容：
当然，如果没有相关的经验，这些建议也许并没有什么实际帮助，下面让我们在具体的情境下分析几个常见的原版Minecraft的运行日志（对安装有Mod的Minecraft的分析在另一节）。

下面开始具体分析。
[21:56:40] [Client thread/INFO]: LWJGL Version: 2.9.4
开始准备渲染系统和输入设备。这是游戏启动过程中的一大鬼门关，很多游戏崩溃就发生在这里，如LWJGL本地库链接异常，发现不支持的显卡和一些难以解释的JVM崩溃。

开始加载资源包，顺便初始化一下声音系统（OpenAL）。

继续加载资源包，这次是加载贴图。

复述功能初始化完成

内置服务端的启动，日志中体现出的是启动开始、生成通讯加密密钥、加载成就和生成出生点区块四个过程。
[21:58:11] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 2269ms behind, skipping 45 tick(s)
这是服务端卡顿的标志，倒数第二句为卡顿时长。
[21:58:12] [Server thread/INFO]: lovexyn0827[local:E:e164c517] logged in with entity id 1927 at (222.5, 68.0, 259.5)
客户端成功地连接到了内置服务端。
[21:58:12] [Server thread/INFO]: lovexyn0827加入了游戏
玩家加入游戏。这段时间前后如果因为某些原因导致连接断开，那么客户端可能会卡在加入世界的界面下。
[21:58:17] [Server thread/INFO]: Saving and pausing game...
[21:58:17] [Server thread/INFO]: Saving chunks for level '新的世界_1.12'/overworld

[21:58:19] [Server thread/INFO]: Saving chunks for level '新的世界_1.12'/the_end
暂停时内置服务端会进行自动保存。
[21:58:31] [Server thread/INFO]: Stopping server
[21:58:31] [Server thread/INFO]: Saving players
[21:58:31] [Server thread/INFO]: lovexyn0827 lost connection: 连接中止

[21:58:32] [Server thread/INFO]: Saving chunks for level '新的世界_1.12'/the_end
玩家退出时关闭内置服务端并保存世界。如果服务端因为某些原因被卡在某一游戏刻，那么当那一游戏刻结束后（有时可能需要数分钟）这几条日志才会被输出，服务端才会开始关闭，期间游戏会被卡在保存世界画面中。

由于没有网络连接，正版验证报错，联网后不会出现。能走到这一步，Java版本过低的问题就基本上可以被排除了。
[14:25:44] [Render thread/INFO]: Setting user: 用户名
正版验证过程结束的标志。
[14:25:44] [Render thread/INFO]: Backend library: LWJGL version 3.2.2 build 10
开始准备渲染系统和输入设备。这是游戏启动过程中的一大鬼门关，很多游戏崩溃就发生在这里，如LWJGL本地库链接异常，发现不支持的显卡和一些难以解释的JVM崩溃。
[14:25:46] [Render thread/INFO]: Narrator library for x64 successfully loaded
复述功能初始化完成。这条日志具体输出位置出现的很隐蔽，应该是打开进度条界面时（MinecraftClient:855, openScreen()）NarratorManager类被加载进而引发了复述功能初始化。

表明客户端与内置服务端成功取得联系，之后服务端会下发配方书、计分版、指令列表等一系列数据。
[14:26:42] [Server thread/INFO]: 用户名 joined the game
玩家正式加入游戏。这段时间前后如果因为某些原因导致连接断开，那么客户端可能会卡在加入世界的界面下。

[06:11:08] [Server thread/INFO]: Saving chunks for level 'ServerLevel[新的世界]'/minecraft:the_nether
玩家退出，内置服务端保存世界并关闭。只有在最后一个游戏刻运算完毕后这一过程才会开始，意味着如果那个游戏刻因为一些原因运算了很长时间，客户端在那些时间里就会被卡在保存世界界面中。
