以上为日志
dashboard 版本 v5.3.2
请问有什么办法或者可以调整的参数， 让日志不被截断

这是日志追踪的打印限制，不是消息本身被 Broker 截断。The 1801 bytes of this log are truncated 表示 trace 输出超出上限。
先在 Dashboard 里新建一条 Trace（诊断工具 → 日志追踪），把这两个参数调一下再复现：

  • Payload 编码：Text（JSON payload 用这个）
  • Payload 限制：调大到 8192 或直接关闭限制（默认是 1024 B）

这个是最新版本上的图，如果你没有看到这个选项，应该就是旧版本上还没有这个功能。可以考虑升级版本。
